A very popular landscape shrub installed by both professionals and homeowners is Loropetalum or Chinese fringe. This shrub offers attractive foliage and flowers along with being evergreen.
When you visit a nursery to select this plant for your landscape, realize that there are now many selections of Loropetalum available. Learn about a few of the common selections in this recording of ‘In the Garden’, with UF/ IFAS Extension Escambia County Horticulture Agent Beth Bolles, so that you are successful at matching the appropriate plant with your landscape needs.
Air potato leaf beetle attacking the invasive air potato plant.
Air potatoes got you down? Have no fear, for the Air Potato Challenge is coming to Leon County!
Register now to attend the Air Potato Challenge event on May 18, 9 a.m. to 12 p.m. at the FAMU Center for Viticulture and Small Fruit Research (6361 Mahan Drive, Tallahassee, FL) and receive a supply of air potato beetles to use on your property.
After years of testing, air potato beetles became available as a biological control in 2012 to help combat the invasive herbaceous perennial air potato vine (Dioscorea bulbifera). Air potatoes arrived in south Florida from China in the early 1900s and have steadily crept north until they are now invading the Panhandle Region. Fortunately, air potato beetles have dietary requirements that are very specific, relying strictly upon air potatoes to complete their life cycles.
This is why a team of researchers and Extension agents have come together to help spread air potato beetles as a biological control strategy. Many agencies and counties are involved in this effort, including UF/IFAS Extension St. Lucie County, UF/IFAS Indian River Research and Education Center, the Florida Department of Agriculture Division of Plant Industry, the USDA, Florida Fish and Wildlife, UF/IFAS Extension Leon County, and Florida A&M University.
A healthy lawn is a joy to stroll, relax and play on. It can also be part of an environmentally friendly landscape. But, sometimes it can seem to be a mystery on how to achieve that lush, healthy lawn in the Florida environment. Since we have lots of sandy soils and experience long periods of warm and hot weather, many suppose that giving the lawn lots of water will help do the trick. Not so.

But what harm can it cause to give the lawn plenty of water all the time? Isn’t that a good thing? No! Overwatering your lawn can lead to the following problems:
Development of fungal diseases (fungi love a moist environment!)
Increased insect pest pressure
More rapid thatch development
More weeds (those little emerging weed seedlings thrive on consistent moisture!)
Some weeds, like dollarweed and sedges, can be an indication of overwatering
A shallow root system when frequent, light watering is applied
Washing away of fertilizer down into the soil past the root system
Higher water bills.
Our lawns need, on average, about 1/2 to 3/4 “of water a week during the summer. This recommendation changes depending on soil type, shade, temperature, wind, and season. To figure out how long to run your sprinklers, watch this YouTube video from UF/IFAS.
We recommend running your automated system only when your lawn shows signs of needing water such as:
Bees, butterflies and other insects play important roles as pollinators in our environment. Over 50 major crops in the United States and at least 13 crops in Florida depend on honey bees. Many native plants in natural areas also depend on insect pollinators for reproduction. In Florida, over 300 bee species play a role in pollination!
Many factors affect the health of our pollinators. One of those factors we can easily control in our own landscapes is exposures to pesticides. How are bees and other pollinators exposed to pesticides? Here are some of the major routes:
Drift of pesticides sprayed in breezy/windy conditions
The erosion of contaminated topsoil blowing in the wind
Direct feeding on pollen and nectar of treated plants
Contact with pesticides that have blown onto plant surfaces
Contact with water transpired by leaves of treated plants
Pesticides that move down through the soil to affect ground dwelling bees and other insects
Did you know that bees become statically charged when they fly causing particles in the air to attract to them?
What are some ways that we can reduce the risk of exposure to pollinators in our landscapes?
Avoid treating areas containing flowering weeds/plants with insecticides. If you must treat your lawn with an insecticide, and it contains flowering weeds, mow the lawn and remove the flowers just before applying the insecticide.
If you must apply a systemic insecticide to your lawn, leave a buffer strip of several feet between the lawn and the border of landscape beds with flowering plants. This will prevent the flowering plants from up taking the systemic product.
Postpone any insecticide treatment until after all blooms have fallen from flowering ornamentals. Never apply an insecticide to blooms or flowering plants.
Avoid the use of neonicotinoids as this class of insecticides can be more toxic to bees than other classes of insecticides. There are many effective alternatives.
Pruning is one of the most controversial aspects of maintaining crapemyrtle. Traditionally, many crapemyrtles are routinely topped, leaving large branch and stem stubs. This practice has been called “crape murder” because of the potential impacts on the crapemyrtle health and structural integrity. Topping is the drastic removal of large-diameter wood (typically several years old), with the end result of shortening all stems and branches.
Hard pruning (topping) stimulates crapemyrtle sprouting from roots, upper stems, or the base of main stems. If basal and root sprouts are not removed, one or more may form woody stems that eventually compete with existing main stems. These additional or competing stems may result in poor form and structure, such as stems that rub against each other.
Topping typically delays flowering up to one month compared to unpruned crapemyrtle. On some cultivars, topping also shorten the season of bloom. Long-stem sprouts emerge just below large-diameter cuts that result from topping. These sprouts usually develop into upright, unbranched stems that eventually flower, often bending under their own weight. Rain or wind storms can cause extreme bending and some will break because they are weakly attached to the main stem.
Topping removes large amounts of starches and other food reserves stored within branches. Topping dramatically reduces the size of the plant canopy, ultimately decreasing the plant’s ability to produce food (starches) through photosynthesis. The large branch stubs caused by topping result in large areas of exposed wood that allow access by insects and wood-rotting organisms, weakening the plant’s structure. Finally, topping results in many dead stubs throughout the tree.
Proper pruning may be needed, just like any other tree. Lower limbs of crapemyrtle are removed to increase clearance for pedestrians or vehicles. Stems are cut to increase branching. Other pruning may be conducted to direct growth away from structures, stimulate flowering, and remove spent flowers, seed capsules, and dead or damaged branches and twigs.
Properly placed, crapemyrtle is a low-maintenance plant needing little or no pruning. Problems with overgrown, misshapen, or misplaced crapemyrtle can be greatly reduced with proper selection of crapemyrtle cultivars, proper plant selection at the nursery, and proper placement in the landscape. For more information on cultivar selection go to: http://edis.ifas.ufl.edu/mg266.
If pruning is necessary, use the following recommendations:
Pruning for safety may be done anytime. This may involve removing damaged or weak branches or pruning lower limbs for pedestrian and vehicle clearance and visibility.
Pruning to improve plant structure, redirect growth, or alter plant shape and appearance should occur when plants are leafless and dormant–typically December through February. Although this can be accomplished at any time, without leaves, the branching structure is clearly visible to more easily determine appropriate branches for pruning.
Prune to remove crossing or rubbing branches.
Prune dead, damaged, or diseased branches at the branch collar.
Remove vigorous branches growing toward the center of the canopy.
Severe pruning should be performed late in the dormant period. Pruning too early might stimulate new growth that could be damaged by low temperatures.
Every gardener should know a thing or two about farming. Join UF/IFAS Extension at the 2018 Panhandle Fruit and Vegetable Conference to not only learn about market vegetable production, fruit and nut production, and much more, but also to attend the pre-conference farm tour and listen to a speech by the Keynote Speaker, Dr. Joy Rumble, an Assistant Professor in the Department of Agricultural Education and Communication at the University of Florida.
