Step by step

  1. Start seeds indoors Feb 16 – Mar 2 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 27 – Jun 8, 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.
