Description
Long and thin or round and fat, eggplants range from egg- to melon-sized and come in a rainbow of colors, including purple, pink, white, orange, and green. They're used in hors d'oeuvres, main courses, grilled dishes, and pickled condiments.
Care and cultivation
Eggplants are attractive, tender herbaceous perennials normally grown as annuals. Their purple flowers and large, purple-tinged leaves combine with colorful fruit to make them a stunning addition for a vegetable or flower garden. Eggplants are a warm-weather crop, thriving in heat and humidity that makes other crops wilt. It's best to grow eggplants in a part of the garden where you haven't grown related crops, including tomatoes, potatoes, and peppers, within the last 3 or 4 years. Many pests of eggplants are pests of these related plants too.
Site Selection
Select a site with full sun and fertile, well-drained soil. repare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.
Planting Instructions
Start plants indoors in flats or peat pots about 2 months before the soil warms up in your region, or buy nursery transplants just before planting. Cover planting beds with black plastic to warm heavy clay soils. Set out the transplants when all spring frost danger is past, spacing plants 18 to 24 inches apart.
Care
Add an organic mulch to retain moisture and control weeds after the soil has completely warmed up, about 1 month after setting out transplants. Water plants during the summer if rainfall is less than 1 inch per week. Contact your local County Extension office for controls of common eggplant pests such as flea beetles, Colorado potato beetles, and tomato hornworms.
Harvesting
Most eggplants can be harvested when they are 4 to 5 inches long. The skin should be shiny; dull skin is a sign that the eggplant is overripe. Use a sharp knife and cut the eggplant from the plant, leaving at least 1 inch of stem attached to the fruit.
Days to Maturity: 100 to 150 days from seed; 70 to 85 days from transplants.
Harvest: Fruit should be large, shiny, and uniformly deep purple in color. When the side of the fruit is pressed slightly with the thumb nail and an indentation remains, the fruit is ripe. Long, slender, Japanese eggplant may be ready to harvest from finger or hotdog size. When fruit is dull in color and has brown seeds, it is too ripe and should be discarded.
