Grape in a Zone 8 season
Zone 8 gives about 224 frost-free days. Grape needs roughly 150 days from transplant. That leaves about 74 days of slack, so there is room for a late start or a second planting.
How to grow grapes
Plant dormant vines in the cool part of the year on a sturdy trellis. A perennial that rewards patient pruning with fruit in a few years. Give the vines good air flow, since humid, rainy weather invites mildew.
