Most gardeners will tell you that transplanting grape vines is a risky proposition. Grape vines can live for more than 40 years, and some plants have lived more than 100 years. Older plants can die from shock if they are transplanted. If you must move a grape vine, a new vine or one that has remained in its location for only a few years stands a better chance of survival.
Wait until early spring before the plants wake from their period of dormancy to begin transplanting process.
Prune old hardwood grape vines to within 2 feet of the soil. Make all pruning cuts just above a stem node, which is the point at which a plant's leaves, fruit stems and tendrils emerge.
Insert a shovel into the ground 1 foot from the central vine. Work the shovel around the vine in a circle, remaining 1 foot from the central vine.
Insert a shovel into the groove at the base of the grapevine. Work the shovel under the rootball and gently lift it out of the ground.
Transplant the vine in full sun. Dig a planting hole that is slightly larger than the width of the root ball and slightly deeper.
Pile compost into the center of the planting hole. Scratch compost into the sides and bottom of the hole using a cultivating fork.
Place the rootball into the new planting hole and cover it with dirt. Pat the dirt around the rootball to dislodge air pockets from the sides.
Give the grapevine approximately 4 gallons of water.
