Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Sow seeds 1/4 inch deep in warm starting mix and maintain soil temperature above 80°F for the best germination rates. Eggplant demands the warmest possible spot in the garden; cold soil stunts growth significantly, so do not rush transplanting. Mulch heavily to hold soil warmth and moisture, and fertilize with a phosphorus-rich blend to promote flowering. Harvest fruits while the skin is still glossy, as dull skin signals over-maturity and bitterness.
