Tips & Best Practices
- Start seeds indoors 8–10 weeks before the last frost — eggplant is slow to grow.
- Do not transplant until nighttime temps are consistently above 55°F.
- Use black plastic mulch and row covers to boost soil and air temperature.
- Harvest when skin is glossy; dull skin indicates overripe, seedy fruit.
