Evidence of Native Bees





Pink Knock Out Roses

You can easily notice a friendly visit from a native pollinator, the leafcutter bee.  Identifying which species is harder since there are nine different species endemic to Florida.

 

Good news is that leafcutter bees are beneficial as pollinators for crops such as commercial blueberries and vegetables.  In residential landscapes, inviting ornamental plants with thin leaves such as bougainvillea, roses, and redbud trees are more susceptible to the leafcutter.  The visible damage of circular cuts on the outside edges of leaves will be used to build up their nests and usually will not harm the plants, but this non-aggressive bee species can sometimes nest in hollow rose canes, causing the rose to decline.

Basil Spots

With my mindset lately, when I saw the subject line on Chris's (a loyal listener of In Your Backyard heard on My790am.com) email, I thought to myself, "Oh no, Chris has melanoma..."  Thankfully, Chris does not but his basil isn't feeling well lately.

Here's his question: 

I planed sweet basil (from __________ )  about 3 weeks ago.  Looks like I am doing good, but I noticed some brown spots.  The soil was amended some with compost and ______________ soil for vegetables and flowers. The plant did stress/droop within the first week of initial planting, bounced back up after watering but is doing good now.  Watering is done by hand now at the base of the plant.
 Are the brown spots normal?  Due to fungus? Nutrition deficiency?
 
Thanks, Chris

Chris, good question and the photograph helps answer the question.  Your basil definitely is suffering from Colletotrichum disease.  The disease is identified by the black spots, black haloed rings, and black stems. It occurs when there is a combination of high humidity, lack of air circulation, and the plants are watered often. You will want to get rid of the basil plants that are affected and plant another herb or plant in that location.

When you use plant with soil amendments, especially ones that hold water well, gardeners can overwater plants.  Always check the soil before watering to ensure that you really do need to water.  Never water the soil if the ground is wet, cool, or damp.  Twice a week watering should be enough for amended garden beds in full sun.   Space plants far enough apart that they have plenty of air circulation. 

Thanks for writing Chris!

Free Guide To Identifying Southern Invasive Plants

The USDA Forest Service Southern Research Station has created a free pdf download of invasive plant species, “A Field Guide for the Identification of Invasive Plants in Southern Forests.”

The book is a more comprehensive identification guide to nonnative trees, shrubs, vines, grasses, ferns and forbs invading the region’s forests and other natural areas. The revised guide includes 23 more plant species with updated information on the original 33 species; 241 new photos and images and a new “Resembles” section so users can identify plant “look-alikes.”

The book’s appendix contains the most complete list of nonnative invasive plants in the 13 Southern states, providing common and scientific names for 310 other invading species including, for the first time, aquatic plant invaders.

Complete with color high density photographs, it takes a few minutes to download or you can email:
