About eggplant

Eggplant is a tender, warm-season cousin of the tomato and pepper that craves heat even more than they do. Cold soil and chilly nights stall it badly, but a long, hot summer brings a steady set of glossy fruit. It thrives in containers and raised beds that warm quickly.

How to grow eggplant step by step

  1. 1

    Start seeds indoors on a heat mat at 80–85°F 8–10 weeks before your last frost.

  2. 2

    Grow under strong light and keep warm — cold checks eggplant permanently.

  3. 3

    Harden off, then transplant only after nights are reliably above 60°F.

  4. 4

    Use black mulch or a container to keep the root zone warm.

  5. 5

    Stake taller varieties and feed lightly once fruit sets.

  6. 6

    Pick fruit young and glossy for the best texture.

Common problems growing eggplant

Flowers drop without fruiting

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

Flea beetles shotgunning the leaves

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

Dull, seedy, bitter fruit

Overripe — harvest while the skin is glossy and the flesh springs back to a light press.

🧺 Harvesting eggplant

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.

Eggplant: frequently asked questions

When should you plant eggplant?

In most regions you start seeds indoors 8–10 weeks before last frost, then transplant 2–3 weeks after last frost, once nights stay above 60°F. Timing is relative to your last frost, so find your USDA hardiness zone for the exact planting dates where you live.

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.

Do I need to salt eggplant?

Modern varieties picked young are rarely bitter, so salting is optional — it mostly helps reduce oil absorption when frying.
