Step by step

  1. Start seeds indoors Mar 31 – Apr 14 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 May 12 – Jun 23, 18 inches apart. Plant starts at the depth they grew in the pot.
  4. Water deeply once or twice a week rather than a little every day, and mulch once the soil is warm.
  5. Plant again Jul 10–24 for a fall harvest.
  6. Harvest: Pick the lower leaves and let the top keep growing. Plants often produce from fall through spring west of the Cascades.
