About Eggplant

Eggplant needs a long warm season and maximum heat — more demanding than tomatoes but highly productive in the right conditions.

Start indoors 8 weeks before last frost — eggplant needs a long head start. Needs hot conditions to set fruit. Use black plastic mulch to warm soil. Very productive once established in heat.
