Moderate Plant young plants (starts)

Why these dates

Spokane's typical last spring frost is April 26. As a cool-season crop that handles light frost, this crop doesn't need to wait for that date. In the Inland Northwest, though, the soil usually isn't ready to work until about April 15.

Inland Northwest. Higher, colder interior valleys. Cold springs and an earlier fall mean a shorter season; quick-maturing varieties pay off.

Step by step

  1. Start seeds indoors Feb 25 – Mar 11 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 15 – May 20, 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 20 – Aug 3 for a fall harvest.
  6. Harvest: Cut when heads feel firm when squeezed. Water evenly to keep heads from splitting.

Varieties that do well here

  • Golden Acre
  • Early Jersey Wakefield
  • January King (winter)

Watch out for

Cabbage worms and root maggots. Row cover from planting day prevents both.

Even watering prevents split heads.
