Grow peppers in full sun (at least 6 hours per day) in soil that is rich in organic matter, moisture retentive but well draining.
Choose a site protected from wind.
Keep peppers evenly moist but not wet particularly when blossoms appear and fruit begin to form. Soil that goes too dry can result in flower drop. Keep the soil evenly moist just after transplanting peppers to the garden; avoid under or over watering peppers early on. Add aged compost to planting beds before planting and again at midseason.
Once hot pepper plants are established you can vary the watering. Hot peppers that are deprived of water and become slightly stressed will produce more pungent fruit.
Companion plants. Beets, garlic, onions, parsnips, radishes.
Pests. Peppers can be attacked by aphids, cutworms, flea beetles, and hornworms. Discourage cutworms by placing a collar around each transplant at the time of planting; hand pick hornworms off of plants. Flea beetles and aphids can be partially controlled by hosing them off the plants and pinching out infested foliage.
Diseases. Peppers are susceptible to rot, blossom end rot, anthracnose, tobacco mosaic virus, bacterial spot, and mildew. Plant disease-resistant varieties. Keep the garden clean and free of weeds where pests and diseases can shelter. Remove infected plants before disease can spread. If you smoke, wash your hands before working with the plants to avoid spreading tobacco mosaic virus.
