Needs even more heat than peppers. Small-fruited, early varieties do best west of the Cascades, helped by black plastic mulch or a warm wall. Hot eastern valleys grow them easily.

How to grow eggplant

  1. Start seeds indoors on your city's dates 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 on your city's dates, 18 to 24 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. Harvest: Pick when the skin is glossy and springs back when pressed. Dull skin means it's overripe and seedy.

Varieties that do well in the Northwest

Watch out for

Flea beetles riddle young leaves, and cool nights stall growth. Keep row cover on until plants are growing strongly.
