The muscadine grape is a popular fruit that grows very well here in North Florida. It has smaller leaves than bunch grapes and fruit are harvested singly, rather than in bunches. Theses grapes can be enjoyed fresh and also be used for home wine-making. One of the nice things about growing muscadine grapes in Florida is that they’re rarely bothered by insects or diseases. They can easily be grown in your backyard garden.

Grapes will grow well in a variety of soils here in North Florida. Upland soils with clay underlying at about three feet are ideal. You should avoid poorly drained soils. If the grapes are grown on soil with very good drainage, they should be set in the ground deeper than they were grown in the nursery on land with a high water table. Grapes should be planted on raised beds at the same depth they were at in the nursery.
During the first year, grapes should be fertilized with a quarter pound of 8-8-8 or 10-10-10 fertilizer, applied in bands about a foot away from the plant, soon after growth begins. Repeat applications in April, July and September. Fertilizer rates increase each year, but they should never exceed six pounds per vine per year.
Weeds can sometimes be a problem with muscadine grapes. To get rid of weeds, you can use a good herbicide, or you can cultivate around the plants. The muscadine grape has a very shallow root system, however, so be careful when you’re weeding around the plants. Mulches can be helpful in controlling weeds, but be sure to leave a circle of at least six inches around each vine uncovered.
Grapes need a generous supply of water to survive here in North Florida. In fact, more first-year grapes die from a lack of water than from any other cause. Make sure the plant receives about an inch of water weekly. Muscadine grapes are rarely bothered by insects or diseases. However, a spray program is advised to protect plants from possible damage by black rot or bitter rot. Spraying should begin when the vines are in bloom, and continue a regular two week intervals until about a week before the harvest. For specific information on the proper spray to use, you should contact your local County Agent.
Muscadine grapes mature in August and early September. If you don’t plan to use them immediately, they should be picked from the vine when ripe and stored at 40 degrees Fahrenheit.

As our world and our lives become more centered on technology it seems that all the information we need is just a touch screen away. After all, you are most likely reading this article from a laptop, smart phone, or tablet. While convenient and portable, there are some places you might not wish to take your electronics and one of those places is in the garden. You may say, “Well Taylor, that’s what they make waterproof, shatterproof, dirt proof, etc. cases for!” and I would say that you’re right. However, technology has many limiting factors such as battery life and screen glare. Now believe me, I am by no means disparaging technology! I come from a generation that considers Wi-Fi as necessary as water and an outlet comparable to oxygen. But there is something to be said for having a book in hand when out in the garden. For one thing your neighbors won’t worry about you as they see you march around the garden with your phone in the air doing the “No Signal Dance”. Also, a book is great to have in order for you to jot down any notes or reflections. I would like to list for you a few books that I often reference when I receive calls from homeowners. These books will cover various topics and all of them can be found on the UF/IFAS Bookstore website, the links for each can be found below. If you have any questions contact your local Extension Office and, as always, feel free to contact me and I can give you a rundown on my collection of favorite reference books!

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.
Red Mulberry. Photo credit: Vern Williams, Indiana University, bugwood.org.
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.

One very popular herb for the backyard garden is the evergreen Rosemary, Rosmarinus officinalis which serves as an attractive landscape shrub in addition to its culinary uses. Rosemary grows best in full sun and well-drained soils. When planted in the ground, rosemary can grow 4-5 feet in height and spread. Plants do have beautiful bluish flowers that form in late winter and early spring, providing nectar for bees.
Rosemary is generally a pest free plant but some gardeners may find damage resulting from an insect pest. Rosemary is one of the hosts for the Southern purple mint moth, Pyrausta laticlavia which will lay eggs on several plants in the mint family. Caterpillars feed on leaves along the stems which become matted with silken threads and frass from the insects. As a result of the feeding, leaves are not useable and plants do not look attractive. Heavy populations will stress plants.
Since rosemary is often used to flavor many foods, many people do not want to use an insecticide on the plant. One least toxic option that can be used safely on edibles is Bacillus thuringiensis. The product is specific for caterpillar management and safe for predators that may help manage some caterpillars. Homeowners may also physically remove caterpillars or prune out damaged stems on larger plants.

Herbs are plants that are grown for the special flavor and aroma of their various parts. They are used mainly to season, enrich, or otherwise improve the taste or smell of certain foods. Since they are not classified as vegetables. Since their growth habits and cultural requirements are similar, herbs are often included with vegetables in the garden.
One of the best ways to enjoy year round gardening is to plant an herb garden. Herbs are easy to grow, they require very little care, and they don’t take up much room. Even if you don’t have a large backyard, you can still grow herbs successfully. A small garden bed, a window box, or even a few clay pots, can provide you with fresh, aromatic herbs year round. Herbs are rapid growers and they have a wide variety of uses in the home. They can be used either fresh or dried and when dried they’ll keep for long periods of time.
Herbs are fairly easy to grow. A good garden soil that’s free of weeds and close to a water supply will keep your herbs healthy and growing rapidly. If you can, plant herbs on a narrow strip of land, preferably at the border of your vegetable garden. This will keep your herbs easy to reach. If you scatter them across a wide garden plot, you’ll end up having to walk over the plants to reach and gather them unless you can provide some pathways within your garden. Of course, if you’re growing herbs in window boxes or clay pots, this won’t be a problem.
Dill is probably the easiest and the hardiest herb you can grow. It’s usually planted in late fall and early winter because of its ability to withstand cool temperatures. It may also be planted in the spring. Dill isn’t particularly fussy about its soil so any all-purpose soil that’s suitable for your regular garden vegetables is fine for dill. Another plus is that dill is rarely bothered by any diseases or insects. Fresh dill leaves add excellent flavor to salads and cream sauces, and as a dried herb, dill is well known for the distinct flavor it gives to pickles.
Another popular herb enjoyed by gardeners is sweet basil. This herb is an annual, and it can be replanted in the same area year after year. Basil is also used both fresh and dried. It is widely used as a flavoring for soups, meats and fish. One word of caution: don’t over plant this one. A few basil plants will usually provide more leaves and flowers than an entire family can use in a year.
A few plants, such as sage, balm, and rosemary can be propagated best by cutting. Stems from new growth or the upper parts of older stem make the best cutting for easiest rooting. Cut the stem into 3 to 4 inch pieces each containing a set of leaves or leaf buds near the upper end. To prevent wilting place the cutting in water as soon as they are removed from the plant. A shallow box filled with 4 to 5 inches of a mixture of clean sand, peat, and perlite makes a good root bed. Insert the cutting to a depth of one half-to two thirds their length in the moist mixture; then saturate the mix with water. Place the box in a protected place and keep moist (but not sopping wet) continuously until roots develop in about two weeks. Continue to water until the cuttings are ready to set out in pots or in the garden.
Such plants as thyme, winter savory and marjoram can be propagated by simple layering, which consist of covering the lower portion of the side branches with soil, leaving much of the top of the plant exposed. When the covered part of the stem have rooted, they can be cut from the parent plant and set as individual plants.
Older plants of chive, rosemary and tarragon can be multiplied by dividing the crown clumps into separate parts. These divisions can be set as individual plants.
Mint spreads rapidly by means of surface or underground runners that may grow several feet from the parent plant. The runners, with roots attached, can be removed and transplanted to other locations
Obviously, the list of herbs which grow very well in Florida is quite lengthy, so we won’t be able to go into all of them here. If you can keep in mind just a few points about herb gardens, maybe you can enjoy the virtues of some of these herbs yourself. Remember that herbs are generally very easy to grow and can be adapted to either outdoor garden or indoor container growing conditions. For just a small amount of effort, growing herbs can provide you with year-round gardening satisfaction.
