Eggplants are heavy feeders and benefit from regular fertilization throughout the growing season. Fertilize with a starter fertilizer at transplanting and again at fruit set. Large fruited varieties should have their side branches supported to prevent broken branches. Tie the branches to the string for support. Plants grow to a height of 2 to 3 feet.
Eggplants have their best flavor when they are harvested young.
Early, repeated harvest also stimulates continuous fruit production. At harvest, the skin should be taut and shiny. Fruit that has lost its shine and has begun to change color is overripe and most likely bitter. Purple varieties take on a bronze appearance when overripe, while white eggplants begin to turn yellow. Press the fruit with your finger.
