Canadice is a cold-hardy red seedless grape that thrives in zones 4 through 8, making it one of the most winter-resilient table grapes for northern gardeners. This Vitis labrusca hybrid delivers sweet, crisp fruit with genuine seedless convenience, a rarity for regions where most grapes struggle through harsh winters. Plant it in full sun with 6 inches of spacing and expect vigorous vining growth that rewards you with harvestable fruit within your first growing season.

Highlights
What sets Canadice apart is its remarkable hardiness paired with genuine seedless fruit quality. Unlike many cold-tolerant grapes that sacrifice flavor, this variety maintains a distinctly sweet taste and crisp bite. The vines are perennial workhorses that establish quickly and produce reliably across the colder half of the country where seedless grapes are otherwise impossible to grow.
Common Uses
Canadice shines as a fresh eating grape, pop them straight off the vine for an immediate snack. Their seedless nature and crisp texture make them equally suited to dried preparations as raisins, or for pressing into juice and jelly. The versatility across fresh, dried, and cooked applications gives gardeners multiple ways to use a single harvest.

Care Instructions
Transplant Outdoors
These are perennial grapevine roots intended for direct planting in spring. Expect shipment in mid-March for spring planting season. Prepare your outdoor bed with well-draining soil and space roots 6 inches apart in rows 120 inches apart, allowing ample room for the vining growth habit to establish.
Harvesting
Harvest Canadice grapes when they reach full red color and taste distinctly sweet, the berries should come away from the vine easily when fully ripe. Expect harvestable fruit within one growing season of planting, making this an unusually quick-producing grape variety. Pick entire clusters or individual berries as needed once they've achieved their characteristic red hue and crisp texture.
Pruning
As a vigorous vining perennial, Canadice benefits from annual pruning to maintain structure and maximize fruit production. Prune during dormancy in late winter, removing dead, diseased, or crossing canes and training the remaining growth along your trellis. Regular pruning encourages stronger cane development and improves air circulation, which helps prevent fungal issues.
