"In tropical and subtropical climates, eggplant can be sown directly into the garden. Eggplant grown in temperate climates fares better when transplanted into the garden after all danger of frost is passed. Seeds are typically started eight to 10 weeks prior to the anticipated frost-free date.
Many pests and diseases which afflict other solanaceous plants, such as tomato, pepper (capsicum), and potato, are also troublesome to eggplants. For this reason, it should not be planted in areas previously occupied by its close relatives. Four years should separate successive crops of eggplants. Common North American pests include the potato beetles, flea beetles, aphids, and spider mites. Good sanitation and crop rotation practices are extremely important for controlling fungal disease, the most serious of which is Verticillium.
Spacing should be 18 inch to 24 inch between plants, depending on cultivar, and 24 to 36 inch between rows, depending on the type of cultivation equipment being used. Mulching will help conserve moisture and prevent weeds and fungal diseases. The flowers are relatively unattractive to bees and the first blossoms often do not set fruit. Hand pollination will improve the set of the first blossoms. Fruits are typically cut from the vine just above the calyx owing to the somewhat woody stems. Flowers are complete, containing both female and male structures, and may be self-pollinated or cross-pollinated."
