Growing Tips

  • Eggplant loves heat even more than peppers — wait until soil is 70°F to transplant.
  • Use black plastic mulch to keep soil warm and moist.
  • Harvest while skin is still glossy — dull skin means overripe and seedy.
  • Stake plants when young — heavy fruit can snap branches.
  • Rotate with non-solanaceous crops to prevent verticillium wilt.

Common Mistakes

  • Transplanting too early — eggplant planted in cold soil just sits and sulks.
  • Letting fruit overripen — seeds become hard and flavor turns bitter.
  • Not staking — eggplant can produce 10–15 heavy fruits per plant.
  • Planting near tomatoes or peppers year after year — all are in the nightshade family.

Companion Planting
