Capsicum annuum 'Red Delicious' is a sweet bell pepper grown for its flavorful, blocky fruits that can be picked green or allowed to mature to a rich red. Treat it as a warm-season annual: it grows fast in summer and slows quickly when nights cool or frost threatens.
Set plants outside only after frost danger has passed and the soil has warmed. Choose a spot with full sun for best growth and fruit quality, or use a large container placed where it will get strong daily light. Provide fertile, well-drained soil and steady moisture so the plant does not stall or drop blossoms.
Expect a compact plant about 18-24 inches tall and roughly 24-30 inches wide, making it easy to tuck into the edible garden, a sunny border, or patio pots. Keep weeds down by hand and avoid disturbing the roots; peppers can be temperamental when their roots are stressed.
Feed lightly at planting and again as flowering begins, following your fertilizer label. Water deeply when the top inch of soil dries, and mulch to reduce swings in moisture. In containers, check moisture often during heat and wind.
Harvest fruits with pruners or scissors to avoid tearing stems. Pick regularly to keep production going. At season's end, remove plants after frost and compost only healthy material.
