Step by step

  1. Start seeds indoors Mar 24 – Apr 7 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 28 – Jun 2, 6 to 10 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. Plant again Jul 24 – Aug 7 for a fall harvest.
  6. Harvest: Cut baby bok choy at about 6 inches tall, or whole heads at full size. Harvest before a flower stalk appears.

Watch out for

Flea beetles and slugs chew the leaves. Row cover and iron phosphate slug bait handle both.

Bolts as days lengthen, so get spring sowings in early. Fall crops are the easiest.
