Winter Vegetable Production on Small Farms and Gardens West of the Cascades

By Nick Andrews Heather Stoven Heidi Noordijk Lane Selman Kelly Streit Brooke Edmunds Neil Bell and Victoria Binning

The mild climate west of the Cascades allows farmers and gardeners to grow many winter-hardy crops in the field for winter and spring harvest. A wide range of alliums, leafy greens, brassicas and root crops do well. For farmers, winter vegetable production can provide cash flow outside the normal summer cropping season, more consistent work for employees and year-round relationships with direct-market customers.
