The most common problem with eggplant are flea beetles which eat tiny holes in the leaves. Too small to hand pick, the beetles are easily controlled with insecticides labeled for use in the vegetable garden.

Use pruning shears to harvest the fruit. The stems are tough; twisting and pulling to harvest will only damage the plant. Plan on harvesting when the fruit is still small, about 6-8", and the skin is shiny. Over mature fruit with dull skin and a spongy interior should be discarded. 'Black Beauty' is a standard color and shape. 'Ichiban' is long and thin, and 'Casper' a white-fruited variety.
