Growing Tips

  • Loves heat even more than peppers — wait until soil is 70°F.
  • Use black plastic mulch.
  • Harvest while skin is still glossy — dull skin means overripe.
  • Stake plants when young.
  • Rotate with non-solanaceous crops.

Common Mistakes

  • Transplanting in cold soil — just sits and sulks.
  • Letting fruit overripen — seeds become hard, flavor turns bitter.
  • Not staking — eggplant can produce 10–15 heavy fruits.
  • Planting near tomatoes or peppers year after year.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
