Why these dates

Astoria's typical last spring frost is March 26. As a cool-season crop that handles light frost, this crop doesn't need to wait for that date. On the coast, though, the soil usually isn't ready to work until about March 25.

Coast. Mild winters but cool, foggy summers. Frost is rarely the problem; warmth is. Pick early, cool-tolerant varieties of tomatoes and squash.
