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 April 1.

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

Step by step

  1. Start seeds indoors Jan 21 – Feb 4 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.
  2. Harden off the young plants: about a week before planting, set them outside for a few hours a day, a little longer each day.
  3. Plant them in the garden Apr 1 – May 13, 6 inches apart. Set seedlings in a hole about 6 inches deep so the stems grow long and white.
  4. Water deeply once or twice a week rather than a little every day, and mulch once the soil is warm.
  5. Harvest: Dig whenever stems are an inch or more across. West of the Cascades you can leave them in the ground and harvest all winter.

Varieties that do well here

  • King Richard (early)
  • Bandit (winter-hardy)
  • American Flag

Watch out for

Weeds crowd young leeks. Mulch and weed regularly while the plants are small.

Slow but nearly foolproof. West of the Cascades they stand in the garden all winter, ready to dig as you need them.
