Three primary species of bunch grapes are grown in the United States the European bunch grape (Vitis vinifera), the American bunch grape (Vitis labrusca) and the Summer grape (Vitis aestivalis). Bunch grapes are often called “pod” grapes in rural Georgia since they produce large clusters of fruit. Georgia”s climate is not well-suited to home garden production of European bunch grapes, but American bunch grapes and hybrids between the two species (French hybrids) grow well in Georgia. If grapes are well cared for and sprayed when diseases and insects threaten, you can expect yields of 20 to 30 pounds of fruit per vine. The Summer grape is also an American species and is represented by a few varieties good for wine production. If you want to grow European bunch grapes, consult www.smallfruits.org for the Mid-Atlantic Wine Grape Growers Guide. This is also a good source for more detailed information on growing French hybrid grapes. The spray program to produce good quality European bunch grapes is intensive and generally impractical for home gardeners.

Pierce”s Disease is a bacterial disease spread by leaf-hopper insects that kills susceptible bunch grape varieties. It is very common in middle and south Georgia. Pierce”s Disease has not been a significant problem in areas of Georgia above 1,300 feet elevation (high mountain area). Between 1,000 and 1,300 feet (upper Piedmont area), disease pressure varies greatly from site to site, but home garden plantings of Pierce”s Disease susceptible bunch grapes are generally feasible. Between 700-1,000 feet in elevation, Pierce”s Disease will often destroy the vines of susceptible cultivars within 5 years. Below 700 feet elevation, Pierce”s Disease often destroys the vineyard within 3 years. These boundaries can shift with climate variation from year to year. Below 1,000 feet elevation it is recommended that primarily Pierce”s Disease resistant cultivars be planted.

Best Place to Plant

In the Mountain and Piedmont areas of Georgia, late spring frosts can reduce yields significantly, so plant bunch grapes on elevated sites if possible. In all areas, avoid low spots where cold air settles. The site should be in full sun most or all of the day. Well-drained, loamy sand, sandy loam, loam or clay loam soils are best for grape production. Avoid areas where water stands after heavy rains.


American type bunch grapes and Summer grapes are usually grown on their own roots in North Georgia. European grapes and French hybrids are usually grafted on rootstocks such as SO4 or 3309 to provide increased Phylloxera resistance. On sandy sites (especially in South Georgia), test for the presence of root knot nematodes. If they are present, grapes should be grafted on nematode resistant rootstocks such as “Tampa,” “Florilush” or “Dog Ridge.” Low vigor varieties are often grafted to improve their vigor, this noted in the tables.


Many varieties of American type bunch grapes will perform well in Areas 1 and 2 in Georgia. Also, certain selections of French Hybrid grapes (wine grapes) are suggested for trial in these areas. Several hybrid bunch grapes are worthy of trial in Area 3 of Georgia. (See tables 1 and 2.)

Varieties Suggested for Home Garden Trials in Area 3 in Georgia

Several hybrid bunch grape varieties have been developed which are worthy of trial plantings in middle and south Georgia. All of these have good resistance to Pierce”s Disease, the primary limiting factor to bunch grape culture in the middle and southern portion of Georgia. Table 2 lists suggested varieties for home plantings.

Purchasing Plants

Bunch grapes, unlike muscadines, do not require cross-pollination, so it is not necessary to buy two or more varieties for pollination. You may, however, want several varieties to extend the fruiting season.

Most bunch grapes are sold as 1-year-old or 2-year-old plants. Generally, the 2-year-old plants grow off better and are worth the small extra investment. Be sure to purchase them from a reliable source.

Planting the Vine and Plant Spacing

It is easiest to construct the trellis before planting, but it can be done after planting. Since most bunch grapes are somewhat less vigorous than the native muscadine grape, only 8 to 10 feet of row will be required for each vine. Lay off the rows at least 10 feet apart (12 feet on hilly land). Use straight rows for level or slightly rolling land and contour rows for hilly terrain. Prior to setting the vines, soil test and adjust the soil pH to 6.0 to 6.5 with dolomitic limestone. Most Georgia soils are low in magnesium, thus the need for dolomitic limestone.

To plant, prepare a hole large enough to accommodate the entire root system in its natural spread. Set the plant at or slightly below the level it grew in the nursery. Fill the hole with the natural topsoil and firm it. Do not place fertilizer in the hole. (See section on fertilization.) After firming the soil, water liberally.

Following planting, cut the vine back to a single stem with two to three good buds remaining. After growth begins, select the main trunk of the vine from the stronger of these shoots.

Trellis Systems and Trellis Construction

Normally number 9 wire is used for grape trellis construction. All posts should be pressure treated or made of termite/rot resistant wood such as heart of cedar.

American Type Bunch Grapes

American type bunch grapes are vigorous and have a trailing, downward growth habit. Three high trellis systems are commonly used to train home garden American type bunch grapes in the south: the double curtain (two wire horizontal system), the two wire vertical and the single wire. The top wire is typically 5 feet to 5½ feet above ground level in all three systems.

The Double Curtain Trellis — This trellis system is usually the most desirable of the three systems because of increased yields. The trellis system has two wires 4 feet apart and 5½ feet above the ground. Figures 1 and 2 show details of how to construct the double curtain trellis. A simple T-bar trellis constructed from treated 4″ x 4″ posts can also be used.
