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.

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.
✗ Keep away from
🧺 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
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.
