Eggplants are a real heat lover, and grow best when transplanted between mid-April and the end of August. Eggplants usually hit their peak of production later in the growing season, between August and October, when the daytime temps are at their hottest and before the nights get too cold. When preparing your garden bed for eggplants, loosen the soil in an 18” wide circle and add 6 cups of compost, two cups of landscape mix and two cups of worm castings to each hole and thoroughly incorporate. Eggplants will want to be kept on the dry side and can be watered deeply, once a week. This means 30-40 minutes with a slow trickle, coming from a hose. Give each plant 18-24 inches of space.
