Grape planting zones

Table, wine or muscadine: which grape for your region

In the North, University of Minnesota Extension grows cold-hardy grapes, many of them its own releases: ‘Frontenac’, ‘Frontenac Gris’, ‘Frontenac Blanc’, ‘Marquette’ and ‘La Crescent’ for wine, most of which it says grow very well in zone 4 and do well in zone 3, and ‘Bluebell’, ‘Edelweiss’ and ‘Swenson Red’ among its grapes for eating fresh and for juice. It says seedless grapes generally do poorly in the North, and names ‘Somerset Seedless’ the hardiest of the seedless varieties it has tested in zone 4.

In the Southeast the bunch grapes run into Pierce’s disease. Clemson’s Home & Garden Information Center says South Carolina’s climate is not well suited to growing European wine grapes at home, but that American bunch grapes and some hybrids do well. For the mountains and Piedmont it suggests ‘Concord’, ‘Delaware’ and ‘Catawba’ for eating and wine, ‘Mars’, ‘Reliance’, ‘Saturn’ and ‘Interlaken’ for eating, and French hybrids for wine; for the Sandhills and Coastal Plain, where Pierce’s disease is common, only resistant ones such as ‘Blanc Du Bois’, ‘Lake Emerald’, ‘Conquistador’ and the seedless ‘Daytona’ and ‘Orlando Seedless’.

Further south the native muscadine takes over. UF/IFAS Gardening Solutions says muscadines grow in all parts of Florida and resist Pierce’s disease, and Clemson says they are best adapted from the Piedmont to the coast. NC State Extension’s plant toolbox rates the muscadine for zones 5a to 9b.

Muscadines: one vine or two

Muscadine vines are self-fruitful or female. Clemson says a self-fruitful (perfect-flowered) vine fruits alone, while a female vine must be planted near a self-fruitful one. UF/IFAS says to choose a self-fruitful variety if you have room for only one vine.

Clemson’s self-fruitful list includes ‘Carlos’, ‘Cowart’, ‘Nesbitt’, ‘Noble’, ‘Tara’ and ‘Triumph’, and its female list ‘Fry’, ‘Scuppernong’, ‘Supreme’, ‘Summit’ and ‘Darlene’. It calls ‘Nesbitt’ one of the most cold-tolerant cultivars and ‘Scuppernong’ very cold hardy. UF/IFAS grows ‘Black Beauty’, ‘Fry’, ‘Southern Home’, ‘Summit’ and ‘Triumph’ for eating fresh, and ‘Alachua’, ‘Carlos’, ‘Noble’ and ‘Welder’ for wine and juice.

NC State waits until there is little chance of sub-freezing temperatures before planting muscadines in spring, and the table above dates that for every zone where a muscadine is rated. Clemson sets bare-root vines in late winter, February or March, and says container vines can go in any time with irrigation. UF/IFAS plants bare-root vines from December through February in Florida, at least 10 feet apart.

Planting bunch grapes

University of Minnesota Extension plants in spring, so young vines have the longest time to settle in before their first winter. University of Illinois Extension plants in early spring as soon as the soil can be prepared, a little deeper than the vine grew in the nursery and about eight feet apart. Clemson plants in late winter and early spring.

Minnesota plants the vine with its lowest bud just above the soil and does not mulch, because grape roots like warm soil; it keeps grass and weeds out from under the vine for the same reason. Clemson wants a soil pH of 5.8 to 6.5 and plants away from low spots where cold air settles, since a late spring frost can cut the crop.

Build the trellis first. Clemson puts it up before the vines are planted, and Minnesota says any sturdy fence, arbor or post will do. Illinois uses the four-cane Kniffin system on two wires. Illinois also warns that grapes are among the plants most easily harmed by weed killers drifting from a nearby lawn.

Pruning: most of the vine goes

Minnesota says grapevines must be pruned every winter or spring, before growth begins, and that in an average vineyard 80 to 90 percent of the new growth is cut off each winter, because the fruit comes on new shoots that grow from last year’s wood. Table and juice varieties keep 40 to 60 buds per vine after pruning, and wine varieties 20 to 30.

In the first years Minnesota builds a straight trunk and then two to four arms (cordons) along the trellis. Clemson does the same over three years, and from the fourth year prunes every dormant season, cutting last season’s canes back to short spurs. It says pruning after growth starts makes the cuts bleed sap.

For muscadines, UF/IFAS prunes from mid-January to mid-March and Clemson every dormant season, keeping the trunk and arms and cutting the side shoots back to short spurs.

An old, overgrown vine can usually be saved: Minnesota cuts it back in stages, or to a few inches above the ground, and grows a new trunk from the shoots that come up.

Harvest

Taste first. Minnesota says many varieties turn color before they are ripe. Clemson says that on a vine that is not overloaded, black grapes lose their red tint, white ones turn from green to golden yellow, the berries soften and the seeds turn brown.

UF/IFAS says muscadines usually have at least two harvest windows, from July for some varieties to late September for others, and can be picked one by one or shaken onto a tarp.

Common problems

Clemson names Pierce’s disease, spread by leafhoppers and common in the Sandhills and Coastal Plain, as the disease that kills susceptible bunch grapes; downy mildew and black rot; and the grape root borer, which can destroy a planting. UF/IFAS says muscadines have few problems, occasionally aphids, thrips and the grape root borer, and plants them away from woods to keep deer, raccoons and crows off the fruit.

Do not let a young vine over-crop. Clemson allows only one cluster per two shoots in the third year, and thins clusters in heavy years so the rest ripen fully.

Common mistakes

• Planting European wine grapes in the Southeast. Clemson says South Carolina’s climate does not suit them.
• Planting one female muscadine. Clemson says it needs a self-fruitful vine nearby.
• Pruning too lightly. University of Minnesota Extension removes 80 to 90 percent of the new growth each winter.
• Pruning after growth starts. Clemson says the cuts bleed.
• Mulching under bunch grapes in the North. Minnesota says the roots want warm soil.
• Spraying weed killer on a lawn beside the vines. University of Illinois Extension says drift harms grapes.

Questions

What grapes grow in cold climates?

Cold-hardy hybrids. University of Minnesota Extension grows ‘Frontenac’, ‘Marquette’, ‘La Crescent’, ‘Edelweiss’ and ‘Swenson Red’, many rated for zone 3 or 4.

What grapes grow best in the South?

Muscadines and disease-resistant bunch grapes. UF/IFAS says muscadines grow in all of Florida and resist Pierce’s disease, and Clemson suggests resistant bunch grapes such as ‘Blanc Du Bois’ and ‘Conquistador’ for the Coastal Plain.

Do muscadines need a pollinator?

Female varieties do. Clemson says a female vine must grow near a self-fruitful one, and UF/IFAS says to choose a self-fruitful variety if you plant only one vine.

When should I prune grapevines?

While dormant. University of Minnesota Extension prunes every winter or spring before growth begins; UF/IFAS prunes muscadines from mid-January to mid-March.

How do I know when grapes are ripe?

Taste them. University of Minnesota Extension says many varieties turn color before they are ripe, and Clemson says ripe berries soften and their seeds turn brown.
