This native American vegetable is second only to tomatoes as a garden favorite, and it needs much the same care. Peppers are also ideal for spot planting around the garden. The brilliant colors of the mature fruit are especially attractive in flower beds and in container plantings.

New varieties of bell peppers are released every year, in mature colors ranging from bright red to orange to white, purple, and nearly black. If you've had past problems with diseases such as tobacco mosaic virus or bacterial spot, choose disease-resistant varieties.

Planting
Choose a site with full sun for your pepper plot. Don't plant peppers where tomatoes or eggplants grew previously, because all three are members of the nightshade family and are subject to similar diseases. Make sure the soil drains well; standing water encourages root rot.

Garden centers offer a good variety of transplants, but the choices are greater when you grow peppers from seed. Pepper roots don't like to be disturbed, so plant them indoors in peat pots two months before the last frost date, sowing three seeds to a pot. Maintain the soil temperature at 75°F, and keep the seedlings moist, but not wet. Provide at least 5 hours of strong sunlight a day, or ideally, keep the plants under lights for 12 or more hours daily. Once the seedlings are 2 to 3 inches tall, thin them by leaving the strongest plant in each pot and cutting the others off at soil level.

Seedlings are ready for the garden when they are 4 to 6 inches tall. Before moving the young plants to the garden, harden them off for about a week. Peppers are very susceptible to transplant "shock," which can interrupt growth for weeks. To avoid shocking the plants, make sure the soil temperature is at least 60°F before transplanting; this usually occurs 2 to 3 weeks after the last frost. Transplant on a cloudy day or in the evening to reduce the danger of sun scorch; if this is not possible, provide temporary shade for the transplanted seedlings.

When buying transplants, look for ones with strong stems and dark green leaves. Pass up those that already have tiny fruits on them, because such plants won't produce well. Peppers take at least 2 months from the time the plants are set out to the time they produce fruit, so short-season growers should select early-maturing cultivars.

Space transplants about 1½ feet apart in rows at least 2 feet apart, keeping in mind that most hot-pepper cultivars need less room than sweet ones. If the plot is exposed to winds, stake the plants, but put these supports in place before transplanting the seedlings to keep from damaging roots. To deter cutworms, place a cardboard collar around each stem, pushing it at least an inch into the ground. If the weather turns chilly and rainy, protect young plants with hotcaps.
