Establish Green Foundations

http://www.gutenberg.org/files/19408/19408-h/19408-h.htm
19th c. home of George W. Cable, The Amateur Garden
During the late 19th century, suburban builders planted landscape plants around homes to highlight the grandeur of the property.  Frederick Law Olmstead, founder of American landscapes, advised to ‘take care of the corners, and the centers will take care of themselves.’ Installing opulent shrubs and trees around foundations not only accented homes but created the framework to showcase the architecture of a new century.

 After World War II, houses became less expensive and landscape packages adjusted to budgets of veteran first-time home buyers.  The next generation — baby-boomers— jumped into the middle class. The housing boom continued with smaller yards, less money for landscape budgets becoming the norm.  Today with savvy builders and 21st century science of water and energy conservation leads the way in offering ‘green’ landscapes with their showcase homes.  But for others, the Victorian trend of installing foundation plants continues with the 20th century artificial reality of zero-lot lines and instant landscapes.  You can easily tell the age of an instant landscaped community by the large trees, scantily grassed front yards from the lack of sunlight, and overgrown shrubs blocking the view of the doors and windows. Its five to ten years old.
Example of instant landscaping after one year.
Instant landscapes have a formula:  Pack as many colorful plants around the house as possible to give that WOW factor so you can sell the house quickly.  The buyers move in, loving the landscape, not realizing the costs and work ahead with high maintenance of pruning, pest control, and replacing stressed plants within a few years. 

The first six months is the honeymoon, landscapes look good.  But Olmstead’s advice that the centers will take care of themselves is a lie. Over the next two – three years though, the established landscapes mature and grow into their full size, requiring continual pruning to get to the door, or see out windows, or keep the trees from hitting the roof.  Mold and mildew become issues with the moisture of irrigation hitting the home and lack of air circulation from the shrubs. With bi-weekly or monthly pruning necessary to prevent shrubs and trees from taking over the home, the shrubs succumb to die-back or ‘bare-bottom syndrome’[1], leaving the shrub looking forlorn and sickly.

Bare-bottom syndrome with die-back issues. 
How do you prevent instant landscapes?
  • Use landscape plantings that allow for mature growth.  Take the full width of a plant and divide it by half.  If a tree grows 30 feet wide, plant it at least 20 feet away from house or overhead wires.  Hedge shrubs that will reach 6 feet wide within two years, plant three feet apart.
  • Do not cram perennials and ornamental shrubs together for the instant look.   Instead, plant more perennials and ornamentals appropriately, and then use seasonal annuals, containers, and hanging baskets to provide more color. 
  • Pruning foundation plants should not be necessary.  We shouldn’t put plants in to cut them unless it’s a formal landscape, a standard specimen, or a formal topiary.  If a window ledge is three feet up from the ground, then use a shrub that will only grow to three feet or grow very slowly, so that pruning is an annual landscape chore.
  • Install foundation plants at least two feet away from the foundation or outside of the roof line.  This will allow the foundation plants to receive rainfall, and therefore cut supplemental irrigation, but also keep the soil at the foundation dry.  Keeping the rootball moisture away around the home will also maintain the integrity of termiticide barrier, reducing susceptibility to termites. 
  • Shrubs should have three to four inches of mulch on top of the root ball, leaving the trunk flare visible but only use one to two inches of mulch around the foundation of the home. This will allow the moisture to dry around the house, again providing more termite protection.

How do you know how big a shrub or tree will get? A great landscape database to help determine appropriate size of shrubs and trees is the St Johns WaterManagement District’s Waterwise Landscapes website.   

Correct landscape installation 2008
Same landscape 3 years later.
Green builders want to provide better landscapes that will look great upon installation, are fabulous a year later, and within five years, look natural as if it had always been there.  Green landscapes mean lower upfront landscape budget costs for the builder, getting more bang for your buck while selling the benefits of less maintenance, lower water bills, for the home buyer, resulting in a quicker home sale!

Mother Nature's Cosmetic Peels


I love to get facials and using an exfoliating cream works wonders. It seems Mother Nature likes to get in touch with her feminine side as well and show off her lovely reddish-orange bark as well. 

Called exfoliation, the peeling of bark from trees can be occur normally to healthy trees or as a result of stress and cause decline.

Semi-dwarf Acoma Crape Myrtle
Tree species that normally peel their bark are birches, crape myrtles, Drake elms, paperbark maples, and sycamores.  The bark peels off, usually starting in the second or third year, at the end of its blooming period during late summer to early fall. Colorful smooth bark adds another dimension of interest to your landscape. The striking red orange tree trunk stands out against your evergreen shrubs and trees.


Ulmus parvifolia 'Drake' Elm
Bark can split from receiving too much rain or being overwatered. This can happen to citrus trees, who like their feet dry, when they are irrigated too often, but that is not the same thing as exfoliation.

When you see peeling, there's no need to do anything to the tree. The bark will come off as the tree is ready.  Enjoy the beauty of exfoliation - it does wonders for Mother Nature's complexion.

Bonsai Superstars

Breathtaking! I have always wanted to have the patience and the space (as funny as that sounds) to create bonsai works of art. They are fascinating to me. The eclectic environmental blog, WebEcoist highlights tree art with bonsai superstars, such as Masahiko Kimura, Ben Oki, Lindsey Bebb, Quinquan Zhao, world famous for his penjing (miniature landscapes that combine bonsai with soil, foliage, and rock), Robert Steven and John Naka, dec His most recognizable work, Goshin, resides at the US National Arboretum. It consists of 11 impossibly straight juniper trees.

Ireland's Planting of the Green

County Carlow

Update:  In the current environment about climate change, talk about the selfishly depletion of forest resources here in the United States and around the world is not new. I found that these genealogy archive documents show that 18th century Ireland had also depleted their forestlands for the use of fuel, construction, and industry. The local governments with assistance of English monies provided project grant funds to the Irish landowners and renters to encourage the replanting of two million trees. Despite lack of documentation that all 200,000 trees in Carlow were planted, the tree project seems to have been successful.

Update: With the assistance of Ian McDermott, (no relation) Executive Director of the International Society of Arborists UK, and Moray Simpson, we have found out the mysterious species "phillyears."  It is a misspelling or local colloquialism of the ancient species, Phillyrea latifolia, an olive-like small tree, or large shrub.  Moray found the Latin genus in her book Collins Guide to Trees for British and European trees. Many thanks to Mac and Moray, and I've put the Collins book on my must-have list for my library.



June 1, 2012. I often discuss my first and second generation Scottish and Irish roots. Not tree roots, but family tree roots. I also love researching my heritage and hearing stories of Irish immigrants coming to this country.  I receive genealogy notes from the Irish-American listserv on Rootsweb Ancestry website.  The following page is from the Pat Purcell Papers.  Pat Purcell was born in 1896 and died in 1995 at the age of 99 years old.  Purcell left a huge legacy of historical documents which are being transcribed to the listserv for all to read. They are fascinating. The legal document below is from 1828 and shows the amount and species of trees planted on the private estate of Thomas Bunbury, Esquire in County Carlow. The signed and sealed document's legal and Victorian phrasing is difficult to understand, so I'm not sure if the trees were advertised for documentation of the estate permanently, for the enhancement of the Esquire's rental properties, or for eventual sale to the public. 

I am amazed at the availability of 19th century varieties of trees, including foreign species like American, Dutch, Middle Eastern, Portuguese, and citrus trees.  Who knew we exported American trees to Ireland?  Most people I think, believe it was only potatoes and tobacco that sailed from the Americas.

I'm assuming the Aspalia apples is a phonetically spelled form of Espaliered apples and the Timber Sallow is a broad-leafed willow used for construction and woodworking.  Other misspellings are the Balm of Gilead, which is could be several types of poplar trees and Plumb, which is the spelling used when speaking of measurements.

Another newhorticultural term for me is Elm Quicks, which after researching long and hard, is a British term meaning a hedge-like row of elms.

A species I have not identified is the Phillyears. Is the spelling correct or is it earlier English spelling?  Is it a tree or a shrub? I have contacted Irish arborists and hope to have an answer soon.

Update - Explanation of all the Tree Planting Registrations.
TREE PLANTING In 1814, Benjamin Bunbury claimed : *'that I have caused the lands of Mortarstown, Carlow **to be planted*' with 52 beech and 13 sycamores. He was acting ‘*as immediate agent*’ for his nephew Thomas Bunbury Esquire. He stated that he planned to register the trees at the next general sessions of Carlow in order to avail of the grants. Corruption was clearly to the fore in local politics back then as it was claimed some one million trees were planted in Carlow during this period, which would have made the county one big forest. "By the end of the 17th century a great deal of Ireland's natural woodland had been cut down and timber was beginning to be in short supply. Sir William Petty suggested that two million trees should be planted. It would appear that over 200,000 trees were planted in Carlow between 1770 and 1890. In 1698, the first of seventeen Acts was applied to Ireland to enforce, or at least to encourage, the planting of trees. The provisions of the 1765 Act, stated that, on the expiration of his lease, a tenant could claim for the value of the trees that he had planted, provided that he certified this planting and then lodged the certificate with the clerk of the peace for the county. This exercise resulted in the Register of Trees which have survived for various counties in Ireland. The registrations were recorded at the quarter sessions and published in *The Dublin Gazette.* Subsequently this information was entered in the ledger entitled Register of Trees into which, depending on the diligence of the Justice of the Peace, the original affidavits were copied out in full or in summary form. This information can be useful to genealogists interested in a particular family who had long-established roots in a particular townland or county. Note added 2012 by Michael Purcell : I believe that many of the trees claimed for during this period were not planted, the application was a means of availing of the grant, all one needed was a friendly Justice of the Peace or a fellow Magistrate to witness your signature on claiming the grant.'

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.”

Landscape Designing With Trees


Placement of trees is an integral component of landscape design. Trees provide shade, nesting and food resources for wildlife, and aesthetic architectural beauty for the home. Having a long range vision of what the tree will eventually look like needs knowledge of the species' growth habit to maturation.

You can search for native and non-native trees suitable for your landscape at Waterwise Landscapes. Make sure that when you plant your trees, that proper space is available for root growth, canopy spread, and wild fire protection.

Logger Calls Himself A "Forest Gardener"

In September 2010's issue of Family Handyman , there's a great story about Tim Carroll, an old-fashioned horse-logging operator in Minnesota. Working with clients to reduce the amount of construction impact on building sites, Carroll uses horses to haul away logs instead of modern tractors.
"Conventional logging calls for skid loaders. they not only tear up the woods but also require a lot of trees to be cut down for manuevering room. The horses, on the other hand, just leave a nice, long trail of road apples, and luckily, the remaining trees appreciate those." ~ Trace Larsen
Tim Carroll, a woodworker who also builds custom cabinets says about his work, "We're not loggers - we're forest gardeners."

In Your Backyard: Preparation Is Critical

June 1st signals the first day of hurricane season in the Atlantic Basin. This year NOAA has issued their projections of fifteen hurricanes with eight major storms. The hurricane names will be:

1. Hurricane Alex
2. Hurricane Bonnie
3. Hurricane Colin
4. Hurricane Danielle
5. Hurricane Earl
6. Hurricane Fiona
7. Hurricane Gaston
8. Hurricane Hermine
9. Hurricane Igor
10. Hurricane Julia
11. Hurricane Karl
12. Hurricane Lisa
13. Hurricane Matthew
14. Hurricane Nicole
15. Hurricane Otto
16. Hurricane Paula
17. Hurricane Richard
18. Hurricane Shary
19. Hurricane Tomas
20. Hurricane Virginie
21. Hurricane Walter

How many will hit Florida is yet in Fate's hands. But you need to be prepared!

By June 1st, all your preparations to weather a Category 1-5 hurricane should be completed. That means that you have enough food and water to last a few days, that weather stripping and house renovations are finished, and that your landscape and yard have had a walk-through to remove anything that could damage your house or be windblown during a storm.

Have you inspected your trees? Large limbs in older trees that form a vee and deep crotch could be weak and break or mask a hollow interior that will easily uproot with strong winds. Check out any limbs hanging over homes or are growing together. Look closely for heavy limbs that hang over homes, cross or rub together.

It's important to understand that it's not just pruning a tree, or cutting off limbs that will make it safe and healthy. Cutting trees improperly can make them more dangerous in a storm or and actually reduce the life of the tree. Never try to cut large trees yourself. Always use a certified arborist.

A certified arborist is the only person who should help homeowners make a decision on what limbs to prune or if a tree should be removed. You can easily find certified arborists through the International Society of Arborculture. By inputting your zip code, city, you can find several qualified arborists in your area. If you have an arborist's name or license number, you can verify his certification and good standing.

Before hiring an arborist, it's always a good idea to get three bids so that you feel comfortable that the service is actually needed and with the cost. Professionals understand that you will be calling other arborists for bids. That's part of the business. Don't be afraid to say that you need to check them out or get other bids to price check.

The best advice is to make sure that you're planting the right tree in the first place. The University of Florida/IFAS has enough studies that they now have determined which trees are the most wind-resistant. You can read that study here. It will save a lot of work and money in protecting your home during hurricanes if you select properly for your site.

Planting Trees In Cooler Climates Could Be Hot Issue


National Academy of Sciences has published a study that makes note that planting trees in colder hemispheres could acerbate global warming. Researchers from Stanford University and Universite Montpellier II in France partnered with the Academy.

"Our study shows that only tropical rainforests are strongly beneficial in helping slow down global warming," Govindasamy Bala, an atmospheric scientist who led the research, said.

"It is a win-win situation in the tropics because trees in the tropics, in addition to absorbing carbon dioxide, promote convective clouds that help to cool the planet.

"In other locations, the warming from the albedo effect [sunlight absorption] either cancels or exceeds the net cooling from the other two effects."

[...] "When it comes to rehabilitating forests to fight global warming, carbon dioxide might be only half of the story; we also have to account for whether they help to reflect sunlight by producing clouds, or help to absorb it by shading snowy tundra," study co-author Ken Caldeira said.

However, the authors did not endorse deforestation of the boreal forests as a measure against global warming.

"Preservation of ecosystems is a primary goal of preventing global warming, and the destruction of ecosystems to prevent global warming would be a counterproductive and perverse strategy," Mr Caldeira said.

Makes sense to me. Allowing sunlight to filter through in the wintertime is why Mother Nature provides deciduous trees.
