Eggplant is a slow, deliberate grower. It needs a longer head start indoors than tomatoes or peppers, and it won't hurry once it's in the ground either. The payoff is a long, steady harvest of glossy fruit through the hottest part of summer, once the plant finally gets going.
How eggplant fits zone 10's season
Zone 10b's frost-free window runs about 324 days, from January 30 to December 20. Eggplant needs about 75 days from transplant to first harvest.
