Cabbage in a Zone 6 season
Zone 6 gives about 179 frost-free days. Cabbage needs roughly 70 days from transplant. That leaves about 109 days of slack, so there is room for a late start or a second planting.
How to grow cabbage
Start seeds indoors about 4 weeks before planting out, and set the plants out in the cool part of the year. Steady moisture prevents split heads. Where winters are mild, plant in autumn and harvest before the heat.
