July always brings the blessing of abundant figs on my trees. A new crop waits to be picked and enjoyed every day for nearly a month. The tender sweet fruit can be enjoyed fresh, prepared into jams or used in a myriad of recipes.

The fig (Ficus carica) is native to Asia Minor and the Mediterranean regions of the world and has been cultivated for an estimated 7,000 years. Spanish explorers brought the fig with them to Florida in 1575 and it has had a presence here ever since. Since the fig is adapted to a dry climate in its native regions, the humidity it encountered in Florida can cause fruit to split; but new cultivars have been developed to minimize this problem.
Fig trees usually grow to a maximum of 25 feet and have large bright green leaves that fall in the autumn. Fruit develops from June to August, depending on the chosen cultivar.

Choose a spot for planting a fig tree that receives full sun and good drainage. Once established, figs are drought tolerant and only need supplemental irrigation if we have an extended drought. No structural pruning is required but you can prune to keep the tree from growing so tall that you cannot pick the delicious fruit. Be sure to do your pruning just after the fruit is gone as the fruit develops on the terminal ends of the branches from last year’s growth.
Many figs grow and fruit sufficiently without applied fertilizer, however, a light fertilization with a 10-10-10 with micronutrients can be helpful for small trees getting established and those with reduced fruiting. Young trees can benefit from a ½ pound three to five times from February to August while large trees could use up to 4 pounds per application on the same schedule.
There are a few pests that do damage figs; the most common, though, are the birds and squirrels that get the fruit before you do. Seldom do figs need to be sprayed when grown in the home garden.

There are a number of plants in my landscape that bring back fond memories – plants that I propagated.

There’s a mulberry tree in my backyard that I rooted years ago. I took the cuttings from an old mulberry tree in my hometown. As a boy, I climbed the tree, got in trouble once for coming home with mulberry stains on my clothes. I liked the berries and still do. I have good childhood memories about the tree.
About twenty years ago I visited the property adjacent to my childhood home. The tree was still there. It was during mulberry season. I enjoyed a few mulberries. I took about eight or ten cuttings from the tree. About a year after my visit, the property sold. The new owner bulldozed the tree.
But because of the cuttings that I rooted, the tree still lives and not just in my memory. The trees produced by those cuttings are genetically the same as the parent tree. Essentially, they are clones. The one in my backyard produces mulberries each year.
You too can propagate memories. Not all plants can be propagated from cuttings but many can be. Sometimes trial and error is necessary to learn proper timing in taking cuttings. But most reliable references will provide the time of year to take cuttings based on the plant species.
Stem cuttings should be removed from the parent plant with a clean, sharp knife or pruner. Ideally your cutting should be 4-6 inches in length and not much thicker than a pencil in diameter.
Take the bottom two-thirds of leaves off on each cutting. The cuttings should be stuck upright in a propagation medium. I usually use a good quality potting mix and mix in a little course sand or perlite for better drainage. The cuttings should be inserted deep enough to hold them upright, usually ½ to 1 inch.
To help promote rooting of moderate to difficult to root plants, wound the cuttings by scraping the lower ½ to 1 inch of the stem with a clean, sharp knife. The scrape should remove the bark or “skin.” Then dip the cutting in a rooting hormone covering the scrape with the rooting powder prior to inserting the cutting into the rooting medium.
I usually use a four inch pot, gallon size pot or bedding plant flat with drainage holes as a rooting container. I may stick as many as ten stem cuttings in a gallon size pot. I place the container of cuttings in a shady location outdoors and keep it moist. The cuttings should produce roots in two to sixteen weeks, depending upon plant species and the environment.
After the cuttings have rooted, carefully remove them and individually plant each rooted cutting in its own four inch to one gallon size pot. Keep the potting medium moist but not soggy. After the roots adequately fill the pot, the plant should be strong enough to be planted in the ground.
As your rooted cuttings grow, hopefully they will provide fond memories.

If you’ve been gardening for more than a few years, you may be confused by UF/IFAS recommendations that conflict with practices you’ve used for years. You aren’t imagining things, we do change recommendations based on the most current research available to help you with your agricultural endeavors.
I want to share a few common mistakes that gardeners make based on old recommendations but that research has shown are not the best choices. Check out the list below to see if you can break an old habit or two!
Old Habit |
Current Recommendation |
Throw a little “starter fertilizer” in the hole (or under new sod, seed, etc.) |
It is not beneficial to add fertilizer to plantinghole or under newly installed sod.Quick release (soluble) fertilizer may burn roots if added to planting hole.If applied properly, a slow release fertilizer may be applied to trees and shrubs but should be applied to the top of root ball or mulch following label instructions.Turfgrass grown from seed, sprig, or sod does not use fertilizer efficiently at planting. Wait 30 days to apply fertilizer – after roots have been established. |
Dig the hole twice as deep and wide as the root ball for trees and shrubs |
1.5 times the width of the root ball is good, but planting too deep can be a death sentence.Planting depth should be 10% shallower than the distance from the topmost root to the base of the root ball. |
Mulch 3-5 inches deep |
2-3 inches with a very thin layer directly over the rootball (less than 1 inch) and none touching trunk. This is the ideal amount to conserve water and suppress weeds. |
Native and drought tolerant plants don’t need water |
All plants need water until established – depending on the type and size of the plant, weather, and soil conditions this may take months.Always plan to give a little TLC to newly installed plants no matter how tough they are supposed to be. |

Hurricane Season began June 1. While storm experts are predicting a slower year due to El Nino conditions, it only takes a single storm landing nearby to cause millions in damage, uprooting trees and lives.
Tree damage to homes and property can be devastating, and one of the first instincts of many homeowners when they see a big storm in the Gulf is to start trimming limbs and removing trees. However, it is wise to fully evaluate one’s landscape before making an irreversible decision. Trees are crucial for providing shade (i.e. energy savings), wildlife habitat, stormwater management, and maintaining property values.

University of Florida researchers Mary Duryea and Eliana Kampf have done extensive studies on the effects of wind on trees and landscapes, and several important lessons stand out. Keep in mind that reducing storm damage often starts at the landscape design/planning stage!
- Select the right plant for the right place.
- Post-hurricane studies in north Florida show that live oak, southern magnolia, sabal palms, and bald cypress stand up well compared to other trees during hurricanes. Pecan, water and laurel oaks, Carolina cherry laurel and sand pine were among the least wind resistant.
- Plant high-quality trees with strong central trunks and balanced branch structure.
- Longleaf pine often survived storms in our area better than other pine species, but monitor pines carefully. Sometimes there is hidden damage and the tree declines over time. Look for signs of stress or poor health, and check closely for insects. Weakened pines may be more susceptible to beetles and diseases.
- Remove hazard trees before the wind does. Have a certified arborist inspect your trees for signs of disease and decay. They are trained to advise you on tree health.
- Trees in a group (at least five) blow down less frequently than single trees.
- Trees should always be given ample room for roots to grow. Roots absorb nutrients, but they are also the anchors for the tree. If large trees are planted where there is limited or restricted area for roots to grow out in all directions, there is a likelihood that the tree may fall during high winds.
- Construction activities within about 20 feet from the trunk of existing trees can cause the tree to blow over more than a decade later.
- Plant a variety of species, ages and layers of trees and shrubs to maintain diversity in your community
- When a tree fails, plant a new one in its place.

Considering planting a tree in your landscape, but not sure what will do well?
Baldcypress, Taxodium distichum, is one tree you should consider for your Florida landscape. This deciduous conifer is native to North America and is suited to a wide variety of situations, even difficult ones!
Baldcypress is found naturally along stream banks and in swampy areas, but also performs well in dry situations once established. Not many trees can tolerate standing water or flooding situations, but baldcypress is well adapted to these tough spots. In areas that flood or remain wet the tree will form “knees” that project out of the ground and add a beautiful feature – just don’t plan to mow in areas where these develop. Not restricted to wet areas, baldcypress also performs well as a street tree or in limited root zone situations such as parking lot islands.
This tough tree has a soft, delicate leaf texture and interesting globular cones that start out green then turn brown as they mature. The foliage is light green through the spring and summer then turns a coppery gold before the needles fall in the winter. The trunk has a reddish color that is also attractive and will grow branches low to the ground, but can easily be maintained with a clear trunk in a street tree form.
Baldcypress will grow in full sun to part shade and is adapted to all soil types except highly alkaline (over 7.5 pH). Sand, loam, clay, or muck can all sustain this native tree. Few pests bother baldcypress, but it can be affected by bagworms and mites. Mature size can be in excess of 100 feet, but trees typically grow 60-80 feet tall in Florida.

Uninvited guests can sometimes be fun and entertaining, bringing spontaneity to an otherwise predictable schedule. Sometimes the surprise guest is just an unpleasant distraction with no redeeming virtues.
The unanticipated knock on the door can bring both scenarios to mind. Almost everyone has an enjoyable cousin who regales listeners with amusing tales, and picks up the check for dinner.
Likewise, there are those potential callers with parasitic qualities, the appetite of a market hog, and initiative of a sloth. The Eastern Tent Caterpillar is one such visitor in north Florida.
These native caterpillars build large, thick nests on the branch forks and crotches of many kinds of trees, seeming to always choose the prized specimens highly valued by the homeowner. The silky tent shaped nests are easy to see and identity in host trees.
The caterpillars emerging in the spring of 2015 were laid in the spring of 2014. The adult moth lays her eggs in a single batch in May to July in the panhandle. There are 200 to 300 eggs laid in the group.
The mass of eggs are shiny, reddish-brown and look like dried foam. They are ordinarily about six inches back from the tip of a thin twig in host tree.
In approximately three weeks the eggs contain fully formed caterpillars, but the small caterpillars remain in the eggs until the following spring.
In late-February to mid-March they chew their way through their egg shells ready to eat their host tree that is entering the spring budding period with plentiful tender vegetation.
The voracious larvae immediately infest and, if in sufficient numbers, defoliate plum, cherry and many others. Normally the trees recover after a few weeks, but weakened or diseased trees may die.
When not eating, the newly hatched caterpillars construct their silk tent. The caterpillars use a pheromone trail to guild them back home when foraging is done.
A social insect, the eastern tent caterpillars congregate at their specific tent during the night and in rainy weather, expanding it to accommodate their growing size. These caterpillars do not feed within their nests.
The caterpillars disperse to colonize new areas when maturity is reached. They construct cocoons in protected places once they have sufficiently scattered.
Birds are not attracted to these hairy caterpillars. If they have a heavy concentration of black cherry leaves in their diet, the caterpillars will have a bitter acrid taste.
Parasitic wasps and weather are the two most common causes of caterpillar death. These caterpillars are especially susceptible to cold weather once they have emerged from their eggs.
About two weeks later, an adult moth emerges to begin the process again. Mating and egg laying commonly occur within 24 hours of the moths emerging from their cocoons
These brown moths are nocturnal and are seen flying only at night. They are an inch to two inches wingtip to wingtip at maturity and easy to overlook.

Tent Caterpillars are quick to hatch and eat their way through home landscapes.
Unfortunately, once they arrive for a visit they always overstay their welcome.
