Easy Plant seeds or young plants

Why these dates

Yakima's typical last spring frost is May 8. As a cool-season crop that handles light frost, this crop can go in about 4 weeks before that.

Columbia Basin and low eastern valleys. Hot, dry summers and quick spring warm-up. Warm crops go in earlier than west of the Cascades, and irrigation matters more than rain.

Step by step

  1. Start seeds indoors Feb 13–27 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 10 – May 29, 8 inches apart. If you plant seeds instead, sow them ¼ inch deep.
  4. Water deeply once or twice a week rather than a little every day, and mulch once the soil is warm.
  5. Harvest: Cut outer stems at the base and let the center keep growing.
