Order grapevines in the Fall or early Winter for delivery for early Spring for planting. Some Grape cultivars sell out fast, so order early.
Grapevines are sold in three ways:
Bare Root - these are directly planted in the ground in early Spring.
Cuttings - these must first be rooted by you, then planted.
Pots - these can be transplanted into the ground at anytime during the growing season.
