How to plant

Three steps to a strong start

  • 1. Start seeds indoors on a heat mat at 80–85°F 8–10 weeks before your last frost.
  • 2. Grow under strong light and keep warm — cold checks eggplant permanently.
  • 3. Harden off, then transplant only after nights are reliably above 60°F.

Common problem

Flowers drop without fruiting

Usually cold nights or extreme heat — it resolves as temperatures steady in the warm range.

Common problem

Flea beetles shotgunning the leaves

Cover young plants with row cover until they are established and outgrow the damage.

Harvest

Picking eggplant right

Cut (don’t pull) fruit with a short stub of stem while the skin is still mirror-glossy. Frequent picking keeps the plant productive; a dull, hard-pressed fruit has gone past its prime.

Gardeners ask

Why is my eggplant not setting fruit?

It needs warmth — nights below 60°F or days above 95°F cause blossom drop. Production picks up once temperatures settle into the warm range.
