Crape Murder Is Not Bliss


Bliss is pruning your shrubs and trees correctly. Pruning isn't hard - it just takes forethought and understanding what you want to accomplish.  To prevent stress and diseases, make sure all pruning tools are sterile and kept sharp.

Reader's Digest Indigestion

I have been an avid Reader's Digest for over decades. I have been blessed to have my mother-in-law give us a gift subscription to RD every year for the last ten years. With my limited time to leisurely read, RD is perfect to take with me to my bath at the end of the day, and then over the month, I am able to read RD page by page till the next one lands in my mailbox.

The RD’s new feature, “13 Things Your _________ Won’t Tell You” is one of my favorite reads in the magazine now. With a different career or industry featured each month, I have learned something and at times, been horrified by the other blatant and honest responses the various industries have submitted.
Being a horticulturist/landscape expert, I was professionally disappointed in May’s issue of “13 Things Your Landscaper Won’t Tell You.” While half of the responses were good insights and tips for readers; Number 4,5, and 11 either provided misinformation or only half of the facts. With the other numbered points – some of them great selling points for the benefits of hiring a landscaper - if a landscaper doesn’t tell their clients Number 1, 3, 6, 12, or 20, then the landscaper doesn’t have their clients’ best interests at heart and shouldn’t be hired.

What am I talking about?

#1: Ditch the mower bag. Clippings do add nitrogen to the soil and can reduce the need for fertilizing is true and important to remember, but that’s not the dirty little secret of landscape maintenance. The real fact is that landscape maintenance lawnmowers can be the reason that clients, with maintenance contracts each month, have weeds in their lawn.

Helpful tip: Big question to ask before hiring a potential landscape service: Do you blow, sterilize, or clean off your equipment after each lawn mowing and pruning?

Helpful tip: Leaving the grass clippings on the lawn and fertilizing during the summer contributes to your lawn getting thatch. Grass clippings decompose and add nitrogen to soil. Fertilize in spring and fall, then don’t bag the grass clippings in the summertime. If you need to green up your lawn in summer, use an iron-only product, not nitrogen.

Helpful tip: If you have a severe weed problem, bagging your lawn clippings will keep the weed seeds from going back into the soil to re-germinate again next season.
What #1 should have said: “The reason your weed-free lawn (before you hired me) now has weeds is that my crew doesn’t have time to clean their equipment off after each mowing so weed seeds are spread from house to house and neighborhood to neighborhood.”
 #3: Don’t fill every inch of your space with plants and flowers. The real problem is that homeowners expect “instant landscapes” instead of waiting a short period for the plants to mature. Weeds aren’t an issue with filling every space – in fact – you’ll have less weeds because there will be more competition for water and nutrients from the ornamentals. Landscapers make their profit on installing more plants than is needed.
Helpful tip: Find out the mature size of the plant. Divide the mature width of the plant by half for installing on center and to determine the amount of plants needed for the size of the landscape bed.
What #3 should have said: Except for specimens and standard plants, you can take the estimated plants in your proposal and cut amount in half. Spaced appropriately you’ll have a more natural-looking, more water-conserving, low-maintenance, healthier landscape, within a year.
OR:
What #3 should have said: “Don’t ask me to overplant your landscape beds. By next year, you’ll be paying me more for pruning and chemical spraying that you didn’t want because of competition stress, insects and disease.”
#4: That “pretty”red mulch you love? This tip insinuates that red mulch is bad for the enviroment. Not all red dyed mulches have arsenic! The only mulches with arsenic in it are the CCA (chromate copper arsenate) wood mulches from plywood material. Not all red mulches are from CCA woods. In fact, the process of using CCA wood was made illegal in all states in 2003. Read the mulch bag label to find out where the wood in the mulch originated.

Helpful tip: Use organic mulches from virgin wood or trees from your own property or other locations that you know where they came from. If dyed with oxidized rust (harmless) or food coloring (think about your dog’s red food), they are safe. Look for any indoor or outdoor products you need with low VOC's. Wood mulch from recycled palettes, construction, or salvaged wood contains high percentage of arsenic even with food-safe dyes.

Worth knowing: Arsenic can be found naturally in rainfall and soils, or depending on location, also in major urban areas with history of agriculture and stormwater runoff.

Resources:

CCA Treated Wood Poster 
CCA Research On Red Mulch
What #4 should have said: “If the mulch is the most colorful thing in your landscape, you need to rethink your landscape design.” Mulch should be the aesthetic framework to your landscape picture. It should coordinate with your home design and flower colors. There are landscape design situations where red mulch works, there are many more landscape designs that red mulch does not work.
#5: Hate bagging leaves? You don’t have to. This can be true with understory or tropical trees with small leaves. If the tree is a large oak, elm, sycamore, or other tree species, or you have multiple trees within a close proximity, or you fertilize your lawn frequently with nitrogen applications, then you need to bag those leaves. Year after year, leaf litter can accumulate and decompose, block sunlight, increase soil over important surface roots, increase elevation of yard to create unlevel areas higher than nearby sidewalks and driveways, and cause thatch.
What #5 should have said: Hate bagging leaves? Use your mulching mower and bagger or reverse your leaf blower to suck up leaves during autumn and winter. Use your own bagged leaves in your compost pile and later reuse as mulch or soil amendments for your landscape beds in spring and summer.
#6: Send a sample of your soil to a local agricultural agency to have it tested. Soil samples can be taken to your local agricultural agency but they will usually only test it onsite for pH. Soil analysis to test for nutrient content and fertilization recommendations must be shipped or taken to a professional or land grant university soil lab. There are no soil tests for nitrogen calculations. So you are testing for macro-nutrients of phosphorus, potassium, sulfer, and micro-nutrients that are important for plants to be able to absorb the other nutrients.

Worth knowing: Mulch does not change the pH of soils and soil pH will always revert back to its’ original state. Unless you want to continually have to amend soils to correct pH (not referring to vegetable gardens which need correct soil pH), it’s better to work with the pH you have and select plants that will thrive in that soil condition.
What #6 should have said: Soil pH affects the way plants absorb nutrients. Before I install a landscape or fertilize, ask me to take a pH test of your soil from a local County Extension office or agricultural agency to determine right plant selection for location and correct fertilization applications.
#11: Watch out for a gorgeous plant called purple loosestrife. This tip could be important where loosestrife is invasive and still legal to sell. But loosestrife is illegal or listed as invasive in 34 states. Invasive plants differ from region to region, state to state so naming one plant when there are hundreds of invasive species is not helpful.

Worth knowing: Exotic and native trees or grasses (like bamboo) with underground rhizome root systems can spread hundreds of feet, or more near water bodies.

Check out the Exotic Pest Plant Council’s website for your state to review a landscape proposal or the plants in your yard.
What #11 should have said: Ask me if any of the plants I have on my landscape proposal are invasive or will take over your yard. You dont want the new landscape species to take over your yard and become a high maintenance issue or an issue where you have to apologize for making a problem for your neighbors.
Here are some other “things” your landscaper won’t tell you:
  • "We’ll send the most knowledgeable person to sell you our services, but we’re going to have to send an uncertified, hourly paid, member of the crew to mow your lawn and trim your plants but they don’t know how to identify diseases or insect problems. "
  • Helpful tip: Hire only certified and licensed contractors with crews that are knowledgeable about pest identification. It would be better for you and your landscape if you could hire a landscape professional to come by your house once a month to inspect your property and tell you plants are healthy or find a pest problem before it becomes a major expense and you need expensive renovation.
  • "When I say something needs done – like routine pesticide spraying – I’m not going to tell you that there is no pest preventative out there and routine pesticide applications kill beneficial bugs that could help you easily manage your minor pest issues."
  • Helpful tip: Ask your landscaper if there's an Integrated Pest Management (IPM) control that will be effective for your pest problem.  Declining turf and plants should only be spot-treated after determination pests are still in landscape. Most pests appear and disappear quickly and there is no need to treat with chemicals. Make sure any damaged areas of turf are replaced quickly so that weeds do not germinate and take over.
  • "When you ask me to perform certain tasks, like ‘crape murder,’ you don’t believe me when I tell you that it doesn’t need to be done. Now your crape myrtle looks like a dead stick for months, grows out in ugly, long, branches, suckers more around the trunk, and if it blooms normally in June, now it will bloom months later, and you paid me to do it."
  • Helpful tip: Unless it’s a topiary or bonsai plant, there is no need to prune plants on a monthly or bi-monthly basis. Routine pruning causes die-back and increases stress of the plant. Crape myrtles only need selective pruning if necessary for air circulation, improper direction of limbs, or to cut off seed pods. If a crape myrtle is hitting your house, it’s in the wrong place. No need to hat-rack dormant crape myrtles at the end of January – we don’t hack off the top of other dormant trees like maples, sycamores, or elm trees in early spring, do we?
  • "I’m not going to tell you that the fertilizer we apply too often and around your lakefronts and common areas during the summertime increases the algae bloom in your lakes and retention ponds making the top of the lake scummy; because you then hire us to help clear the algae up by spraying expensive chemicals."
  • Helpful tip: Install native wetland plant species around lakes and retention ponds to absorb excessive fertilizer run-offs and reduce algae blooms. Then show landscaping companies where the 10’ – 15’ buffer zone around lakefront and retention pond area where no fertilizer is to be applied at all. Your lake will be healthier, less maintenance, more natural, and more abundant with birds and wildlife.
The rest of the Reader’s Digest article's "13 Things” your landscaper won’t tell you are either good design tips, proper planting practices, or benefits to the homeowner in dollar value or beauty for their landscape, so why wouldn’t they tell you? A true professional landscaper knows the latest information in best management practices, beneficial and environmental pest control, and how to create a beautiful, low-maintenance landscape for their clients, and they can be trusted.
Homeowners should know how to make sure they get a licensed landscaper who cares about the environment and knows his industry well. They should ask and check references on anyone they interview and remember, the lowest price doesn’t ensure quality – you will get what you pay for. My clients' trust is very important to me and while I don't do landscaping maintenance, I help HOA communities and private clients with their landscaping contracts, issues, and designs.
I sadly doubt that I will hear a response from Liz Vaccariello, the Readers Digest editor-in-chief. Once articles are printed, there’s rarely interest in rehashing content, especially if it’s incorrect. The last time I wrote to a company regarding horticultural misinformation, Snapple advertising agency showed a Chinese panda bear eating the lucky 'bamboo' plant out of the porcelain pot from the middle of the board room desk. It was supposed to be funny (and it was, sort of) except that lucky 'bamboo' that florists and nurseries sell in this country is not real bamboo at all, but poisonous dracaena sanderiana that, if fed to a panda at a zoo by an unknowing person, could hurt them. The marketing company for Snapple never thought to make sure that the "plot" was feasible or correct, and obviously, Snapple thought the marketing company knew what it was doing. Luckily, I didn't hear of any pandas being hurt and, of course, "Don't Feed The Animals" is posted everywhere at zoos.

The Reader’s Digest article "13 Things… series" is a little bit more important and should be reliable and fact-based. Homeowners and everyone who needs to hire a landscaping maintenance service across the country need to really know the facts so they can make good decisions on the lawn care.

Cordylines and Crotons Galore

Scouting for awesome plants at the booths at the Leu Gardens plant sale, I met Mark Peter, grower-owner of Peters Croton Nursery in Fort Pierce, Florida.  He had a magnificent display of cordylines and crotons.

Colorful foliage is a great way to bring light to a shady corner. Cordylines and crotons cover the color spectrum with splashes of whites, creams, and pinks, to red, yellow, orange, and black frilly, elliptical, or piecrusted foliage.  Used in the Florida landscape frequently, both types of plants are often seen painfully in full sun conditions during the harsh hot summers, but cordylines and crotons thrive better and need less water when they get bright morning light but afternoon shade.

Do you know your cordyline or croton's cultivar name?  Their botanical names are cordyline fruticosa and codiaeum variegatum. When I worked in nurseries, I was just used to seeing and hearing Mamay crotons on labels or from the box store order sheet.  But there are several hundred named cultivars of crotons and cordylines.

My favorite cultivars out of Mark Peter's available product?  The creamy white and yellow or pink foliage varieties. I have never seen them for sale in the garden centers.  I do love to use the Picasso's Paintbrush and Zanzibars planted in chimeras representing a blazing fire.  Very nice accent for warm Spanish-themed outdoor rooms.








Both ornamental shrubs need partial sun or shade, moist, rich soils - do not let them dry out, even in winter - and can be fertilized on a monthly (or as fertilizer label recommends)  basis with slow release fertilizer.  They are tropical plants suited best for Zone 10 - 11 but can be grown in Zone 9A and 9B if protected in temperatures below 50 degrees.  Above Zone 9, plants should be grown indoors or in a greenhouse.

Take a look at these fancy plants:

Leu Gardens Plant Sale Spectacular

The annual spring plant sale at Leu Gardens, in Orlando, never fails to be spectacular.  We went with wagon in hand looking for a plant we couldn't live without.  Hundreds of people were there, scooping up plants as fast as they could because if you blinked, someone might buy the plant you were looking at.  On sale were tropical fruit trees, ferns,  succulents, roses, herbs, orchids, flowering tropical and subtropical shrubs and trees, and many more types of plants.

We were able to get nice international variety of herbs:  African blue basil, French thyme, Spanish lavender, dill fenneleaf, pennyroyal, lemon-scented thyme, chives, extra triple curled parsley, and Foresteri rosemary ,that I'm going to add to flowering containers, while Tony found 'Window Box Roma' tomatoes, cubanelles, serrano 'del Sol', and banana peppers for his raised vegetable beds.

I was going to be stalwart and not buy anything else, but I eventually succumbed to getting Kangaroo Paws, Macropidia fulginosa an unusual Australian  xeric native in full bloom and a lovely  'Green Velvet' Alocasia, Alocasia frydeck. 


Kangaroo Paws

My determination to not buy any more plants was easy to keep under control through most of my search until I came to the Orlando Area Rose Historical Society's boothAntique roses are great to grow in Florida with very low maintenance, no pest - no disease issues. Depending on the variety, they can bloom over and over again all year round.  Reading the sign's descriptions, one caught my eye:  "Heavily fragrant, long-lasting pink cabbage roses." I fell for the 'Duchesse de Babrant' tea rose.  Into the wagon it went with my other terrestrial indulgences.

Another unique find was a bamboo obelisk that folded up easily.  Tony was adamant that the $15 cost was a bargain for all the details, material, and labor involved in making it.  We'll use it to allow our beans to grow up.  

Unusual plants and finds were the 'Mammalaria plumosa' and Episcia  cupreata 'Pink Brocade' hanging baskets, terrariums with fluttering butterfly devices, pvc bird garden accents and wrought iron plant holders.

Great start to our spring garden.

Install Your Own Rain Barrel

We haven't had a lot of rain, but now is the time to start thinking of all the rain we get in the summertime and make good use of it. A great way to harvest the rainfall is with rain barrels.  They are easy to install and are now legal for use in all communities including HOA's.  The Florida-friendly statute states that HOA's cannot prohibit rain barrels. 


We'll be talking to Jerry Butler today from Industrial Containers Services in Zellwood.  His company recycles 55 gallon drums as rain barrels available to homeowners inexpensively.

 
The rain barrels cost $38 plus tax.  Very reasonable, especially when purchasing multiple barrels to irrigate your lawn compared to a water bill. To contact Industrial Container Services and purchase a rainbarrel, call 407-889-5500.

Jerry Carris, The Master Gardener



Jerry Carris, harvested more than vegetables and flowers.  An Orange County master gardener for over 20 years, Jerry harvested love, good will, and friendships. He loved everybody and encouraged them to be their very best. My heart ached when I heard that Jerry passed away yesterday.

Jerry, a redhead - with freckles, too - would stop by my office at the Orange County Extension office and give me hugs and encouragement. He was a strong supporter of myUF/IFAS Florida Yards & Neighborhoods program through the City of Winter Garden, and of my weekly gardening radio show, "In Your Backyard. Jerry would call in frequently into "In Your Backyard" with answers to my audience's vegetable questions and to promote the Master Gardener clinic open on Tuesdays at the Mid-Florida Research Center in Apopka.

Jerry was recognized in November 2009 as the Florida Master Gardener of the Year by the University of Florida.

I will miss you, Jerry. God speed home.

NASCAR's Tidy Track

Juan Pablo Montoya #42
Crashes during a NASCAR race usually means oil spills which endanger the professional drivers. Before the race can continue, the NASCAR officials clean the track with TIDE granular detergeant. Years ago, that would have meant phosophorus pollution from the watered down soap product but due to the Clean Water Act, detergeants no longer contain phosphorus pollutants.



What tickled me is how they put the detergeant on the oily track.  They used a garden fertilizer spreader. It did the trick! The race continued with Matt Kensath winning the Daytona 500.

Fruitful Signs of Spring

Having an edible landscape requires patience or a love of seasonal changes. Non-tropical plants that produce fruits usually go dormant in the fall and winter season. With warmer temperatures, the plants emerge from their sleep with lovely flowers. This landscape plant palette includes apples peaches, plums, nectarines, persimmons, pomegranates, carambola, and was just installed at the end of November.

No Rain? Best Way To Help Your Plants

I think I saw a rain drop yesterday.  That was it.  A rain drop.  Here in Central Florida we are now facing our third month with below normal rainfall and heading into a dry spring season.  Add summer time temperatures to the lack of rain and we have stressful conditions for our landscape. 

The good news is that we know that with these weather patterns that we can control how we take care of our landscape.  We can adjust our irrigation, reduce our fertilization and pruning, replenish our mulch, but what else can you do to help your plants handle the temporary drought cycle?

You can add amendments to your garden beds and surrounding shrubs and young trees. Adding organic materials to your sandy soils will help keep the moisture in the ground, provide nutrients that will help plants thrive, and reduce the amount of garden chores that usually come from having 'less than optimum' sand.

Myakka Sand
Our state soil 'Myakka' was designated in 1989, because Florida (an Indian word for 'Big Waters') has more total acreage of Myakka sand than any other soil type. This native soil which is wet sandy soil with an underground layer of organic subsoils is not found in any other state. 

While most new residents from up North like to complain about our dirt. Its not bad. It just is. Myakka sand can provide good drainage, easy to dig in, and does have macronutrients and minerals in it.

Yet sandy soils do not retain moisture very long and can have microbacterial conditions that allow for quick decomposition, leaching nutrients, and nemotodes. Adding organic amendments to your soils is a great way to help your plants survive easier during hotter, dryer periods.

How much should you add?  For a typical 10 square feet, you can add one bag (20 lbs) of top soil, one bag of peat moss, and one bag of manure.  Or you can substitute similar amounts of mushroom or your own seasoned compost.  Work the amendments into the top six to eight inches of your garden bed or apply it around to your shrubs and trees and work it into the ground.

Be careful not to add green compost ingredients, i.e. coffee grounds, manure, in large amounts to your plants as they can have unintended consequences such as increasing acidity or binding nutrients up.  Add fresh coffee grounds, tea leaves, etc to your compost pile and let them age.

New USDA Plant Hardiness Map

After years of discussion and debate, the new USDA Plant Hardiness Map is ready. The previous map was developed in 1990. The new gardening zone map, broken into zones of ten and five degree termperature increments, now has thirteen zones with the newest zones 12 and 13 having low winter temperatures  of (50-60 degrees F) and (60 - 70 degrees F). For background on how the new map zones were arrived at, Tony Avent with Plant Delights Nursery in Raleigh, NC, one of my favorite plant catalog nurseries in the world, was a part of it from the beginning and provides history:
On August 18, 2004, USDA formed a technical review committee of 23 people including yours truly. The group consisted of nurserymen, crop researchers, foresters, climatologists, and others. The committee had a number of meetings at the USDA headquarters in Maryland and many subsequent meetings by phone.

The details of the map making process was quite fascinating. The first few meetings were spent hashing out what we wanted in the map. Several of us had pushed for a 30-year map, which would more closely echo short term natural temperature fluctuations, and the USDA agreed. Another of my requests to create an a, b, c, and d breakdown for each numbered zone was delayed until the future.

We also wanted a map that would allow more temperature interpolations between weather stations, which would take into account things like lake and mountain effects which were missing in the previous map. The process then progressed to the USDA to gather the data and create the map with their in-house staff. A complication arose when their in-house algorithm specialist was commandeered by the Department of Defense and sent to Afghanistan to run algorithms to locate Osama bin Laden. During this time, the specialist would join us via conference call from a safe place in Afghanistan...I’m not making this up.

After two years, the map was supposedly ready as the committee members gathered in Maryland for the unveiling. We were never privy to exactly what went wrong, but the map we saw showed all of the US getting colder, which was certainly not the case. My best guess is that someone reversed all the data. After this debacle, the map trail went cold for nearly a year, during which time the USDA decided in 2007 not to complete the map in-house, but instead to outsource the project to the PRISM (Parameter-elevation Regressions on Independent Slopes Model) Climate Group at Oregon State.

After PRISM completed their initial map, we were shown a draft map via phone conference. The rest of the year was spent going back and forth about areas which the review team felt were not zoned correctly. During this time, more data sites were added to those regions of concern, either from Canadian, Mexican, or military data. Finally in April 2008, the technical review team finished their work and the map was back in the lap of the USDA for publication. The subsequent 3 years and 9 months were spent by USDA trying to figure out what colors to make the zones and then finding a website that could host the map without crashing like their previously launched food pyramid...I’m not making this up. Whoever said that the Federal Government moves slowly was spot on...hence the reason the most recent climatic data in the map is 6 years old.

The USDA map has two versions, a static map where you can select your state and zone or the interactive map where you can input your zip code and you go right to your city and find your gardening zone.

The new map reflects the warmer temperatures from microclimates from winds, bodies of water, slope of the land, and urban heat islands but the USDA makes a valid point that this new realignment should not be used as an indication for global warming.

I agree. The previous USDA map from 1990 used data from a twelve year time period of 1974 to 1986.  The new map uses data from the years 1976 to 2005. The weather is cyclical and since 2005 I've seen even colder temperatures during the winter here locally than normal.  It will be interesting to see the next gardening zone map to see if the two-thirds degree higher temps reach one degree.

The Best Time To Plant A Tree Is Now

Myrtle Oak
Teresa Watkins copyright 2012

Florida's Arbor Day, the third Friday in January was designated as a holiday to celebrate trees. I was asked to speak at the City of Mount Dora's tree planting ceremony at the historic Simpson house.  The following is from my speech:

Trees are the oldest living organisms on earth. Trees produce many of our basic necessities in life. Trees fulfill our lives 24 hours a day with better goods, food, entertainment, sports, and communication. In the 17th century, when the first settlers came to our east coast shores, they were amazed and thankful for the bountiful forests. Over a century later, millions of acres of trees had become homes, buildings, churches, and transportation. When the pioneers ventured west, they encountered for the first time, our prairie ecosystems. There was no protection from shade or winds. There were no trees for construction or fuel. They had to build their homes out of prairie sod. Agriculture was hampered by soil erosion. It was a hard life being a pioneer on the prairies.

In 1872, J. Sterling Morton, editor of Nebraska’s first newspaper, went to the Nebraska State Board of Agriculture and proposed a holiday and contest to plant trees on April 10, The holiday was called Arbor Day. Prizes were awarded to cities, counties and people who had planted the most trees. That first Arbor Day, over one million trees were planted in Nebraska. It changed the state forever. Today Nebraska has over 1million acres of forests.

In 1885, Arbor Day became a legal holiday and other states adopted the practice of planting trees on their own designated Arbor Day. In 1970, President Richard Nixon proclaimed the last Friday in April as National Arbor Day. Florida celebrated Arbor Day for the first time in 1886. Later, state foresters changed the date of Florida’s Arbor Day to the third week in January because it’s an optimum time to plant trees. Because of the great work, the city of Mount Dora has done over the years in protecting and planting trees, Mount Dora has received designation as a Tree City USA community.

The United States contain 8 percent of the world’s forests. And because of Arbor Day and an awareness of the valuable resource of trees through conservation and education, there are more trees in the United States then there were 100 years ago. We now use renewable species of trees for manufacturing.

“According to the (FAO) the Food and Agriculture Organization, forest growth has exceeded harvest since the 1940s…by 1997; the volume of forest growth was 380 percent greater that it had been in 1920.”

Trees provide us with nearly half of the materials the United States manufactures. And actually, the average American uses the equivalent of a tree about 100’ tall and 18’ in diameter. Over 5,000 products that we use on a daily basis come from trees. You can easily recognize building materials, furniture, paper products, but did you know the following products also come from trees?

Chemicals and resins from trees are used as key ingredients for paint, varnish, adhesives, asphalt, artificial vanilla flavoring, cereals, chewing gum, hair spray, mouthwash, soaps, shampoos, tires, and toothpaste.

Cellulose, found in tree cell walls, is used as a food thickener for snacks, milk shakes, ice cream, cake frosting, and pancake syrup. Cellulose is also used in items you can’t eat such as eyeglass frames, egg cartons, steering wheels, hairbrush handles, cellophane, and camera film.

Some little known facts about trees:

• One large tree can lift up to 100 gallons of water out of the ground and discharge it into the air in a day.

• Trees are in essence big batteries. They trap more of the sun's energy than any other group of organisms on earth.

• Only one tenth of the sun's energy is trapped by organisms -- trees account for 50% of all energy trapped by organism.

• If you take its weight into consideration, almost 98% of a tree is made up of six elements: carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur.

• If a birdhouse is hung on a tree branch, it does not move up the tree as the tree grows.

• Different parts of the tree grow at different times of the year. A typical pattern is for most of the foliage to grow in the spring, followed by trunk growth in the summer and root grow more in the fall and winter.

• Most trees do not have a tap root.

• Tree roots do not grow very deep. Most tree roots are in the top 12 inches of soil.

• Tree roots often extend two to three times the width of the tree.

• There are over 400 billion trees on the planet or to personalize it, there are about 61 trees per person.
With the increased promotion and appreciation of trees from Arbor Day, Americans began to select their state trees. While I won’t expound on the fact that palms are not trees, our state tree is the Sabal Palm, Sabal palmetto. Our national tree is the oak tree, which Mount Dora has many magnificent examples. The century-old live oak trees that you see throughout Mount Dora are endemic to the soils surrounding the city and had to be one of the many reasons the Simpson family decided to homestead here in 1874.

Sabal palmetto

 The significance of trees can be seen in our literature, songs, national parks, vacation memories, and the heart-wrenching sadness people feel when massive oak trees are ripped down by hurricane-like storms as they were here in Mount Dora in the spring of 1993 and historic ancient trees, such as the Senator are destroyed by fire last week. 

Chionanthus virginica
by Teresa Watkins copyright 2012
Planting trees is a wonderful way to celebrate humanity and the earth It’s important to teach the value of native ecosystems and the proper locations for trees to create healthier and waterwise landscapes. It’s important for Floridians to protect and plant more native species as we are doing today. The Lake and Hills Garden Club, researched the planting site, and selected a native tree that would thrive in Central Florida with low maintenance. The Chionanthus virginica, the American Fringetree is zoned for 9a, grows to be 12’ to 20’ tall and 10’ wide. It needs moist to dry soils with an acidic pH. It thrives in full sun or morning sun and afternoon shade. The Fringetree produces white flowers in early springtime. Another reason, the garden club members liked the native tree, also called Old Man's Beard, because it not only provides food but also nesting resources for wildlife.

Native plant species are important to keep ecosystems and habitats diverse and healthy. Native trees from the time they emerge as seedlings to the time they are mature provide environmental niches for many types of wildlife in various phases of their lives. Young seedlings are of greatest value to early-successional wildlife that requires thick brushy cover, such as rabbits and songbirds. Young trees do not produce a significant amount of mast (fruit) until maturity, usually around 20 years old, but young trees can seen as important places for resting and insect foraging.

Florida pines and other fast growing trees provide little food sources but are an excellent source of winter and roosting cover, and they can provide important foraging substrate for insect-eating birds, especially migrating warblers like woodpeckers and warblers .

If we lose our native plant species, we will endanger valuable wildlife and bird populations. The creatures and habitat that awed and inspired the first settlers in the 19th century and the 20th century tourists seeing Florida for the first time could disappear.

How do trees benefit humans? One large tree can provide a day's supply of oxygen for up to four people. Trees in our landscapes reduce air conditioning and heating bills by providing shade from the sun and windbreaks from the cold winds. Shading windows and walls can lower AC costs by 25 percent. Landscapes with mature trees can increase property values by 25 percent. Seven year old boy and girls climbing and sitting in a tree canopy contemplating life or looking through the air at the rooftops has immeasurable benefits. We should all climb and sit in trees more. The world would be a better place.

I hope today that this celebration of Arbor Day will increase awareness of the beautiful native tree species we have here in Florida. I wish that everyone attending will go home and assess their yard for the proper site conditions and plant a native species that will enhance their landscape and increase the multiple benefits that trees provide Mount Dora.

As the Chinese proverb says: “The best time to plant a tree was 20 years ago. The next best time is now.”

The Secret of Cyclamens


Fanciful cyclamens are associated with our holiday season. Blooming in winter, these beautiful red, fuschia, pink, and white, woodland bulb plants remind me of our native columbine that seems to hang upside down with their petals reaching up to the sky.

Cyclamens can seem difficult to maintain and are often treated as annuals and tossed away after they start to decline but if you understand their needs and their growth pattern, you can keep the plant for several years.

Cyclamens need bright sunlight, moist but not wet soils, and cool temperatures. Do not place near heating vents or under hot lights. Since the biggest cause of decline is rotting from excessive moisture, its important to allow the plant to dry out between waterings. So if you water the top of the plant, just make sure it doesn't stay on the crown long or keep the soil wet.  Like African violets and primroses, this African native benefits from high humidity and watering from the bottom, although the cyclamens do not get the foliage damage when their leaves get wet. 

Fertilize with a diluted solution of liquid fertilizer every two weeks while blooming.  Cyclamens like temperatures in the 70's and unless a hardy species, do not take temperatures under 50 degrees.  They do not like hot summertime weather.

After flowering, cyclamens should be placed in a cool, shaded location with good air circulation. Do not water and allow the plant to go dormant during the summertime. Keep the tubers and soil dry.  At the end of this dormant period before you start watering again, you can transplant into a larger pot or change out the soil in the existing pot. 

If you continue to water the plant during the summertime, and you do it correctly, the plant may not go into dormancy.  In September, resume watering and place in bright light.  The cyclamens should reappear for another new year holiday season.

Free Gold For Your Garden




One of the best soil amendments you can add to your yard is mushroom compost.  A by-product of mushroom farming, mushroom compost is rich with macro and micronutrients, good bacteria, and organic soil enhancements that improve water infiltration and retention. Its great to add to sandy and clay soils.  And while this soil amendment is one of the best, its not the cheapest to add to your soil. 

But not this week! Today through Saturday from 7:00am to 3:00pm, the Monterey Mushroom Farm in Zellwood, Florida is giving away free mushroom compost.  Bring your own containers or truck beds.

Their location is 5949 Sadler Rd Zellwood, FL 32798, and their telephone number for more information is
(407) 905-4000.

Mushroom compost is derived from all organic materials such as hay, straw, horse bedding, chicken litter, cottenseed meal, cocoa shells, and gypsum.  It can used to amend soils before sod laying, adding plants to your garden beds, prevents destructive artillary fungus from establishing, decreases the need for liming soils, and reduces the need to fertilize for a year.

Simple Resolutions and Smart Solutions for 2012

Happy New Year! I hope this season of reflection and assessment will help you garden with soul and create an environment that will help you become healthier, wealthier, and wise. My four part series of resolutions this year are simple. With the economic times, I’m looking to working smarter in my yard, invigorate myself and my landscape, and recycle what works to save dollars and time.  Here's the first of the New Year series - the three areas of my landscape I need to work on:

Resolution: Use my compost pile more often.
I have a great compost bin that holds a bounty of hardworking earthworms and humus. But because my yard is already at a level elevation, I don’t usually take the time to incorporate the wonderfully organic matter into my soil as much as I should. It’s ridiculous to have this valuable resource and not use it. This year I’m going to use compost more to replace my tired soil with the nutrient rich humus. I’m going to put those good earthworms to work in my yard. 

Resolution: Spiffy up a boring corner with an easy care, low water use container garden.

It’s been six years since I designed my front landscape and it is in need of rearranging and invoking new life. I’m going to dig up my northwest corner “foundation” shrubs and move them around the yard like sofa furniture till I’m happy. Then I’m going to add a new colorful container with colorful xeric perennials, annuals, and a vine or groundcover that spills over, to the corner like a new end table with a beautiful lamp. Oh, that gives me an idea… solar lighting for an uplifting night time display.

Resolution: Create a seating area in my garden.

While I have “floors” of walking paths in my front and backyards, and “walls” of foundation plants, I haven’t decided on seating. Do I want wrought iron, cement or wood furniture? I have wrought iron rocking chairs that are ideal for the garden but do I want to take them off the patio? I also have wood that Tony could make into a swing. I sometimes see aged cement benches in yard sales and on Craig’s list. Don’t pass them up. Deciding on what type of chair I want will help me select the flooring underneath, whether it’s recycled bricks, pavers, or flagstone.

 If I do those two garden projects and incorporate my compost, I will be very satisfied at the end of the year to achieve those goals. Stay tuned for the after pictures!

What are your gardening New Year Resolutions?

Tomorrow, will be the second part for getting off to a good start in the New Year.  I'll provide some simple solutions to help you save money, make better use of what you have, and take time to enjoy living in your garden.

Are You Ready For Some Winter?


In Florida, we can always wear shorts on Christmas Day, but we must not forget that we have a winter season. In the Sunshine State, our winter arrives with a cold front either in the two weeks before Christmas or within the following two weeks after the New Year. With the La Nina weather pattern this year, Central Florida's coldest temperatures so far will occur tonight and Tuesday night. Is your landscape ready for freezing temperatures?

  • Make sure your plants are hydrated before a freeze.
  • Do not run sprinklers systems during freeze.
  • Use frost blankets or large boxes to keep plants insulated.
  • If using anything other than frost blankets, ensure that the material is not touching the plants' foliage.
  • If boxes, sheets, or other material is used, it must be removed each morning and replaced before sundown.
  • Don’t overwater palm trees before or after a freeze.
  • If palms are damaged - use a copper fungicide as soon as possible.
  • Healthier plants and palms survive winter better.
While meteorologists are predicting a mild winter, this only means that we won't be seeing many freezing nights. Make sure you have frost blankets on hand for those tender tropical plants.  If any plant damage is noticeable, try to resist the urge to prune plant vigorously until until mid-February. 

California Scientists Release Citrus Psyllid Predator

Tamarixia radiata
California scientists just released the Tamarixia radiata - a predator wasp that attacks our dreaded Asian citrus psyllid.

UC Riverside Executive Vice Chancellor Dallas Rabenstein and Mark Hoddle, the director of the Center for Invasive Species Research, released Tamarixia radiata – tiny, stingless parasitic wasps that lay eggs in ACP nymphs – in a citrus grove near the UCR Botanic Gardens. A total of 281 wasps (95 males and 186 females) were released.



Over the next several years, UCR and California Department of Agriculture Food and Agriculture (CDFA) scientists will raise thousands of Tamarixia for release throughout California. The Tamarixia larvae will eat the ACP nymphs, killing them, and emerge as adults about 12 days later. Adult female Tamarixia also eat other ACP nymphs, killing many in the process.

Why Are My Citrus Leaves Curling?

Ring Around the Carrot


A Swedish woman harvesting carrots in her vegetable bed, also found her jewelry.  Lena Pahlsson lost her wedding ring sixteen years ago. Despite looking high and low for it, she never found it until last week when digging in her garden.

What a lucky day for her!  I wonder how many other jewelry pieces have been lost while digging in their backyard? This is where a metal detector would have paid off!

Medieval jewelry found in Vienna garden.

Things I've found in my garden.

Interesting things found digging.

Myself personally, I've found marbles, old plastic army toys, golf balls in my yard (I think they flew off an I-4 truck and bounced into my garden.)

Garden Furniture For The Ages

Found these lovely romantic armchairs at Lukas Nursery in Oviedo.  The comfortable, blue chairs made out of a cement resin, look like they were designed for an Alice in Wonderland fantasy.   I can picture them sitting on a lakefront landscape of a picturesque mansion.  The price would require a mansion. They are selling for just under $1000 for the pair.

Tis The Season For Christmas Bird Counting

"And a partridge in a pear tree."


Its' time for the Christmas Bird Count again! The Audubon organization sponsors the annual event each year during the Christmas holidays. Happening from December 14, 2011 through January 5, 2012, the volunteer army of bird-watchers count the various species seen in their yards, cities, and wildlife preserves.  The festive activity to involve people to help birds with a friendly bird experience. 

The data collected will help provide information on species populations and migration trends. Over 50,000 observers in 2000 locations from the Artic Circle to South America's Tierra del Fuego will participate.

You still have opportunity to get involved by contacting your local Audubon group.  You must be 19 yeas old to register and participate and there is a $5 fee which helps defray local expenses of counting equipment and materials.


I wonder if someone will see a partridge in a pear tree?  Probably more like cardinals with snow expected on Christmas Day for our northern feathered friends.

Here's a slideshow I took of birds visiting my mother-in-law's birdfeeder on New Year's Eve 2008.

Mistletoe - Friend or Foe?


Celtic and European traditions have long associated mistletoe with our Christmas holiday.   The American oak mistletoe, Phorandendron serotium, is found in deciduous trees, mainly laurel oak trees, making it easy to see in the wintertime.  Mistletoe can also infest elms, hackberries, sycamores, and wild cherry trees. 

Mistletoe is a friend of butterflies and birds. The epiphyte is the sole host plant for the blue hairstreak butterfly.  The evergreen succulent leaves hold berries that are spread from tree to tree by birds and wind.

Despite the wildlife benefits and jolly seasonal use, mistletoe is a parasite.  Sapping the water and nutrition from its host, mistletoe can kill stressed trees.  Deciding on whether to remove mistletoe should be based on the location of the pest. If it is located in the tree close to the ground, then a homeowner should be able to remove it easily. The mistletoe roots must be removed to eradicate it.  Cutting the branch off six inches below the mistletoe's location.  But if it is in the higher branches of the tree, have it removed by a certified arborist to prevent damaging the tree's structure.

Mistletoe is easily seen in autumn.
The other method of removing mistletoe is by using a chemical growth regulator, Ethephon, that can only be applied in winter time when the tree is dormant. Ethephon is only available thought a licensed pest control operator. 

Mistletoe is poisonous, so be careful to keep out of range of pets and animals. Wash hands and clothing with hot soapy water after pruning or touching.

So is mistletoe friend or foe?  I'll let you decide.
