Cover crops build soil while you’re not looking. Sow them to protect bare ground, feed soil life, fix nitrogen, loosen compaction, and hold nutrients through our rainy winters. This collection includes both traditional European workhorses—clovers, vetches, grains—and Pacific Northwest natives such as blue wildrye and native annual flowers that support pollinators while improving structure and organic matter. Plant in fall to overwinter, or in spring as a short rotation between food crops. Cut, mulch, or incorporate before seed set, and let your soil do what it was designed to do.
