Concord grapes are a full-flavored grape preferred for jelly and juice. The vines grow wild in many parts of the country and can be propagated by seeds, cuttings or layering. However you obtain your vines, transplant them in the spring as soon as the soil can be worked to allow plenty of time for the roots to establish and the trunk to develop before the first frost.
Prepare a well-drained location with full sun or light shade. Perform a soil test and adjust the pH to between 5.0 and 6.0.
Dig a hole large enough to accommodate the spread-out roots. Soak bare roots in a bucket of water containing a small handful of bone meal for one to two hours. Loosen pot-bound roots of container-grown plants.
Place the concord vines in the hole at the level the originally grew. Spread the roots in the hole and cover with soil.
Prune the vine to one vigorous cane. This cane will become the trunk. Shorten the cane, removing all but two strong buds. Remove all sprouts during the first year, until the trunk reaches the height of the trellis. Tie the cane loosely to a stake using cotton twine.
Wait until two weeks after planting to fertilize. Spread 8 oz. of 10-10-10 fertilizer beneath each vine, approximately 6 to 12 inches away from the trunk.
Water the vines regularly during the first spring and summer. Established vines need to be watered only during dry weather. Apply 4 to 6 inches of organic mulch at the base of the vines. Drip irrigation or a soaker hose is ideal for providing even moisture to concord grapes.
