Scoville heat units 2,500 to 5,000
Planting Space 12 to 48 inches apart, depending on type.
Soil requirements Peppers need well-drained, nutrient-rich soil. Amend soil with 3 to 5 inches of compost or other organic matter prior to planting. Soil pH should be 6.2 to 7.0. Water requirements Keep soil consistently moist throughout the growing season. Mulch soil to reduce water evaporation.
Common issues Plants drop flowers when daytime temps soar above 90º F. Few pests bother peppers, but keep an eye out for aphids, slugs, pill bugs, and leafminers. Humid weather (especially in gardens with heavy soil that doesn’t drain well) can invite fungal diseases like leafspot. Harvesting Check image on plant tag (or at the top of this page) to learn what your pepper looks like when mature. Some peppers turn red, yellow, or other colors at maturity. Others are ready in the green stage, but will turn red if left on plants. Use pruning shears or a sharp knife to cut peppers with a short stub of stem attached. Pulling peppers by hand can cause entire branches to break off. Fruits store longer for fresh use if you don’t remove the stem, which can create an open wound that’s ripe for spoiling.
