Why these dates

Forks's typical last spring frost is April 20. 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.

Difficulty: Easy
Sun: Full sun in spring; afternoon shade in summer
Spacing: 8 to 10 inches apart for heads
Planting depth: ¼ inch deep (it needs light to sprout)
Frost: Handles light frost
First harvest: About 50 days after planting

Step by step

Start seeds indoors Feb 11–25 in trays or small pots under a grow light or in your sunniest window. Or skip this step and buy young plants (starts) at a garden center.
Harden off the young plants: about a week before planting, set them outside for a few hours a day, a little longer each day.
Plant them in the garden Mar 25 – May 20, 8 to 10 inches apart for heads. If you plant seeds instead, sow them ¼ inch deep (it needs light to sprout).
Water deeply once or twice a week rather than a little every day, and mulch once the soil is warm.
Plant again Aug 20 – Sep 3 for a fall harvest.
Harvest: Pick outer leaves as needed, or cut whole heads when full. Harvest in the morning for the crispest leaves.
