Gardening in the Pacific Northwest

A region with lush greenery, rain aplenty, mild seasons, gray days, no shortage on slugs, and some of the best soil in the country comes with many challenges — and many opportunities. Gardening in the Pacific Northwest means cool-weather crops such as greens, root crops and cabbage-family crops will generally thrive, but you may have to take extra care to get high yields of heat-loving crops such as tomatoes and peppers. Starting these summer crops plenty early indoors can give you a jump start. 

Giving cool-weather crops an early start in spring and keeping a later planting going into fall and winter can be easier in the Northwest gardening region because winters are typically mild. Try cold frames, low tunnels or a hoop house for all-season growing (these resources on year-round gardening can help).
