I grew up with muscadine grapes. I liked them as a kid and still enjoy them today. In my opinion, they are a southern late summer and fall treat.
Not everyone shares in my fondness for this native fruit of the Southeastern United States. If you did not grow up here, muscadines may be an acquired taste. They are different than the bunch type grapes that most are accustomed to eating. As a matter of fact, most first timers require some instructions in how to eat a muscadine. Nowadays you can search “how to eat a muscadine” on the internet and find written instructions and even short videos on how to eat this grape.

Muscadines have thick skins (hulls) and contain fairly large seeds. Some muscadine purist may pop the entire fruit in their mouth, bite down and eat hull, pulp, juice and seeds. The few people that eat hull, seeds and all may do it for health benefits. The skin and seeds are full of antioxidants and nutrients. But most people do not like the thick and sometimes bitter hull or seeds. So, one technique is to place the grape with the stem scar facing upward in your mouth and squeeze or bite the grape. The sweet juice and pulp will burst into your mouth. The thick skin is then removed and discarded. The seeds are contained in the pulp. It can take some practice removing the seeds from the pulp while in the mouth. Some people enjoy the juice and spit out the pulp with seeds. Others use their teeth and tongue to remove the seeds and then eat the pulp. Some swallow pulp with seeds.
Apparently, muscadines were a pleasant find by the early European explorers to our area. Many names have been used to denote this native grape in the wild including Bullace, Bullis and Muscadine. ‘Scuppernong’ was the first named variety of the bronze muscadine discovered growing in the wild in North Carolina in the mid-1700s. Even though there are now numerous named varieties of the bronze muscadine such as ‘Carlos’, ‘Fry’ and ‘Summit’, many southerners still refer to all bronze types as Scuppernong. Purple or black varieties are commonly called muscadines.
Muscadines range from bronze to dark purple to black in color when ripe. There are more than one hundred improved varieties from which to choose.
There are fruit types that grow well in North Florida and that do not require a lot of space. For high yields they do need a spot that gets direct sun for at least half the day. An area only 10 by 10 feet can support a gratifying amount of fruit production.
Some of the best fruit choices for small areas are rabbiteye blueberries, blackberries and muscadine grapes.
The rabbiteye blueberry is native to the Southeastern United States. Blueberries require a soil pH below 5.3. So, it’s advisable to have your soil tested to find out what the pH is before planting. Mixing peat moss into the soil can lower the pH, if needed. There are many rabbiteye blueberry cultivars. Be sure to plant at least two cultivars together for pollination. Here is a link with more information on blueberries for Florida. https://edis.ifas.ufl.edu/publication/MG359
All of the other fruits like a soil pH of 6.0 to 6.5. Garden lime can be used to raise the pH but only if you have the results of a reliable soil test indicating how much lime is needed. Your County Extension Office can help you determine how to have your soil tested.
Blackberries are productive if you select the correct cultivars. Cultivars adapted to Florida produce large, attractive fruit. Some are self-fruitful while others require a pollinator. Some have thorns while others are thornless. Some grow more erect while some have a trailing growth habit, requiring trellising. ‘Brazos’ is a late fruiting cultivar that does well in our area and does not require cross-pollination but it does have thorns. Here is a link with more information on blackberries for Florida. https://edis.ifas.ufl.edu/publication/hs104
The muscadine grape was one of the pleasant surprises found by the early colonists in the Southeastern United States. An extensive breeding program has resulted in many improved cultivars. Scuppernong is a variety of muscadine. Other popular varieties include ‘Cowart’, ‘Fry’, ‘Carlos’, ‘Summit’, ‘Higgins’, and ‘Nesbitt’. There are many others. Some are self-fruitful while others require a pollinator. There are cultivars that produce bronze, black, red or purple fruit. Some cultivars produce larger fruit, some have a higher sugar content and are sweeter. Muscadines are ready to harvest in late summer to early fall. Some mature early season, mid-season or late season, based on the cultivar. Here is a link with more information on muscadines for Florida. https://edis.ifas.ufl.edu/publication/HS100
Even though these fruit plants can be grown with limited space, they do require some care, including correct fertilization and pruning. Mid-December to mid-February is the best planting time for these fruit plants.

This is the time of year to be on the watch for purple-stained sidewalks and driveways – a sign that ripe muscadine grapes are falling from above. The muscadine grape (Vitis rotundifolia) is a native Florida vine that has been enjoyed by Native Americans, colonists, and contemporary Floridians alike. In addition to the classic muscadine and scuppernong, a light-colored variety of muscadine, there are five other native species of grape (Vitis spp.) to be found growing in natural areas or along woodland edges. All are edible, however, the muscadine has the largest, tastiest fruit.
Many north Florida gardeners have some species of grape growing in their landscapes and consider it a weed due to its aggressive growth. Unfortunately, since the vines are functionally dioecious (separate male and female plants) and most wild plants are male, it is unlikely that those annoying grapevines at the garden’s edge will ever bear fruit. But every now and again, luck strikes! That’s why finding a purple-stained sidewalk or parking area is such an exciting event. I have some of these locations saved in my memory to visit this time of year, especially since all the grapevines in my own property have yet to bear one fruit! If necessary, control methods for grapevine in a landscape include repeated pruning back or the use of herbicides. Muscadines and other grapes are intolerant of shade so will eventually perish if cut back and located under a canopy of trees or shrubs.

Good News! There are plenty of varieties bred for the backyard and commercial fruit grower. Since muscadines are native, they require little, if any, pesticides, making them a great choice for a sustainable landscape or orchard. The vines can be grown up an arbor or a complete vineyard trellis system can be built for maximum harvest. A UF/IFAS fact sheet called “The Muscadine Grape” (publication #HS763) contains all the information needed to choose the right variety, design a vineyard, and implement the best pruning, irrigation, and fertilization schedule.
Whether fresh off the vine or in jams or wine, muscadines are a sweet, summery treat for Floridians.
Every winter season in the Florida Panhandle is different. It can be wet or dry, frigid cold or unseasonably warm. We may have early frosts and early springs, or cold snaps in late march after fruit trees flower.
While we cannot determine the exact time to prune the dooryard fruit trees in our rather variable region, here are some tried and true guidelines for pruning the most popular edible garden plants in northwest Florida.
Blackberries
Blackberries are unusual in that they do not build a large structure and fruit for years on the same branches (in general). They actually fruit on previous years’ growth which then die after fruit production. The canes that produce fruit are called the floricanes. As the floricanes are producing fruit, the blackberry plants are growing primocanes. These are the new canes that will produce fruit for the next season. By then, these canes will have matured in to floricanes. A few new blackberry cultivars exist that produce fruit on new growth as well, but most Florida adapted cultivars are of the standard type. For pruning purposes, it is best to remove the floricanes just after fruiting, but be sure not to cut the new growth (primocanes) because that wood will bear next year’s fruit. For more information about the blackberry, please see publication HS807.
Blueberries
With blueberries older canes need to be removed to make room for younger, more productive canes. When a plant reaches four to five years old it is permissible to remove about 1/4–1/5 of the oldest canes each year which amounts to about one to three of the oldest canes. Performing this task will ensure that no cane is more than three or four years old. Thus, blueberry plantings will be in a constant state of renewal and not become excessively woody and nonproductive. To keep plants from becoming too tall, mature plants can be topped in the summer directly after fruit harvest. Removal of a few inches to a foot, depending on the cultivar, will stimulate the new growth that will bear the next year’s fruit. See CIR 1192 for more information
Temperate Fruit Trees
Pruning of temperate fruit trees (Peaches, Apples, Pears, Persimmons) should be done during the winter dormant period in most cases. This period, generally between December and February allows for some latitude. Pruning later in the dormant season is better in most seasons since trees are more susceptible to freeze damage after pruning, and pruning stimulates the growth of the trees. In Northwest Florida, a February pruning is usually most desirable, depending on the season (namely average high temperatures). Pruning for shape is also done in the summer months if necessary. This task should be limited to removing excessive growth and dead / diseased wood. See HS1111 and HS14 for more information.
Muscadines
Once harvest concludes, it is usually a grower’s natural inclination to immediately prune their muscadine vines. Pruning after harvest in early fall is not, however, best for maintaining plant condition and optimizing next year’s yield, especially if there is an early frost. Early frosts can surprise the plant before sugars have been moved to the roots for storage during dormancy. Therefore, waiting to prune in mid-January to mid-March will ensure that the vine has had adequate time to go dormant and acclimate to the winter season. For more information please see this article titled “Tips for Properly Pruning Muscadines”.
Citrus
Pruning is not necessary for citrus in every case, as it is in many temperate fruits, to have excellent production quality and quantity. Citrus trees perform excellently with minimal pruning. The only pruning necessary for most citrus is removing crossing or rubbing branches while shaping young trees, removing dead wood, and pruning out suckers from the root-stock. Homeowners may choose to prune citrus trees to keep them small, but this will reduce potential yield in a commercial setting, since bigger trees produce more fruit.
Often, maturing Satsuma trees produce long vertical branches. It is tempting to prune these off, since they make the tree look unbalanced. To maximize yield, commercial Satsuma growers allow these branches to weep with the heavy load of fruit until they touch the ground. This allows increased surface area for the tree, since the low areas around the trunk are not bare. Additionally, weeds are suppressed since the low branches shade out weed growth. The ground under the trees remains bare, thus allowing heat from the soil to radiate up during cold weather events. The extra branches around the trunk offer added protection to the bud union as well. If smaller trees are desired for ease of harvest, ‘flying dragon’ root-stock offers dwarfing benefits, so that the mature scion cultivar size will only grow to 8-10 feet tall.
Fig
Figs should be pruned after fruit production, which usually occurs in early summer. In the winter it is fine to remove dead or diseased wood, but drastic trimming will reduce yield since fruit is borne at the terminal of the previous year’s growth. For more information, please consult publication HS27.
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.
