When to Plant Cabbage in Washington

A satisfying crop that stores well. Plant in spring or fall for crisp, dense heads.

The Short Answer

Western Washington is exceptional cabbage country — the cool maritime climate produces some of the finest cabbage in America. The crop can be grown nearly year-round in the Puget Sound region, with winter storage varieties maturing in fall and overwintering types surviving through mild maritime winters to produce spring heads.
