Totally Excellent Eggplants

When you think of eggplants, you probably picture the large purple fruits that have been a garden favorite for generations. But these days, eggplants come in different tastes, colors, shapes and sizes, from snow white ‘Casper’ to bright red ‘Goyo Kumba’ to light purple and white streaked ‘Rosa Bianca’. Regardless of your climate or garden size, there’s an eggplant that’s just right for you.

Eggplants (Solanum melongena)are essential in culinary dishes around the world, such as baba ganoush, eggplant parmigiana, and moussaka. Believed to have originated in India, eggplants were cultivated in ancient China and enjoyed for centuries in the Middle East, Asia, and Africa.

In Europe and the United States, however, eggplants were long considered dangerous, because they belonged to the nightshade family (Solanaceae). This botanical family contains poisonous plants like angel’s trumpet and belladonna. But it also includes edibles like tomatoes. Fortunately, eggplants have earned a solid spot in our kitchens, and deserve a prominent place in our gardens, too.

Sowing seeds

You can start eggplants as seeds or purchase them as transplants. Cold-climate gardeners should consider cultivars with shorter ripening times, such as ‘Bambino’ (45 days) or ‘Little Fingers’ (65 days).

It can be tricky to germinate eggplant seeds, but the advantage is that you’ll find a larger selection in seed catalogs than in garden centers. Start seeds indoors two months before transplanting. Eggplants need at least 72°F to germinate, and bottom heat can help. In the right growing conditions, seeds germinate in seven to 10 days. Place under fluorescent lights when seedlings appear.

Before transplanting outside, harden off your seedlings. This means leaving them outside in a protected place for several hours a day, adding more time each day. They should be sturdy enough to plant in two weeks.

Growing eggplants

Eggplants require warm weather and at least six to eight hours of sun. Transplant eggplants only after temperatures are above 70°F during the day and above 45°F at night. You may need to wait several weeks after the last frost date.

Prepare soil by adding organic matter like composted manure or well-rotted compost. Feed with a well-balanced fertilizer when planting and when plants flower.

Space transplants 2 feet apart, although smaller varieties need only 12 to 18 inches. Water 1 inch weekly. As plants grow, support them with tomato cages, stakes, or wire rings. Mulch well to prevent evaporation, maintain soil temperature, and reduce weeds.

Colorado potato beetles and flea beetles are common pests on eggplants. Try putting up fabric row covers when you transplant seedlings. Dislodge aphids and mites with a strong spray of water. Do this in the morning, so plants dry before evening. If this fails, try insecticidal soap.

Prevent soil-borne fungal diseases such as verticillium wilt by rotating crops. Avoid growing eggplants, tomatoes, peppers, potatoes, and other family members in the same spot more than once every three years. If you don’t have enough space to rotate crops, consider growing eggplants in containers. Cultivars with smaller fruit, such as ‘Hansel’ and ‘Gretel’, are ideal for small-space or balcony gardeners.
