Grape in a Zone 11 season
Zone 11 gives about 365 frost-free days. Grape needs roughly 150 days from transplant. That leaves about 215 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.
