Sunlight: Cayenne peppers thrive in full sun, requiring at least 6-8 hours of direct sunlight daily. Ample sunlight is essential for producing spicy, well-developed fruits.

Soil: Prefers well-drained, fertile soil with a pH between 6.0 and 7.0. The soil should be rich in organic matter, so amend it with compost or well-rotted manure before planting. Peppers also prefer loose, well-aerated soil to encourage healthy root development.

When to Plant: Cayenne peppers are warm-season crops that should be planted after the last frost date in spring when the soil has warmed to at least 60°F (16°C). Start seeds indoors 8-10 weeks before the last expected frost date, as peppers require a long growing season.

Starting Seeds Indoors: Sow seeds 1/4 inch deep in seed-starting mix. Keep the soil moist and maintain a temperature of around 75-85°F (24-29°C) for optimal germination, which can take 7-14 days. Using a heating mat can help maintain consistent warmth.

Transplanting: Transplant seedlings outdoors when they are 6-8 inches tall and the danger of frost has passed. Space plants 18-24 inches apart in rows spaced 24-36 inches apart. Harden off seedlings by gradually exposing them to outdoor conditions over a week before transplanting.

Watering: Keep the soil consistently moist but not waterlogged. Water deeply to encourage deep root growth, especially during dry periods. Mulching around the base of the plants can help retain soil moisture and regulate soil temperature.

Fertilization: Cayenne peppers benefit from regular fertilization. Apply compost or a balanced fertilizer at planting time. Once the plants begin to flower, switch to a fertilizer higher in phosphorus and potassium to encourage fruit set. Side-dress with compost or a suitable fertilizer every 4-6 weeks during the growing season.

Mulching and Weeding: Apply a layer of mulch around the plants to retain soil moisture, suppress weeds, and keep the soil temperature consistent. Hand-pull weeds carefully to avoid disturbing the shallow roots of the peppers.

Staking: Cayenne peppers can become heavy with fruit, so consider using stakes, cages, or trellises to support the plants and prevent them from toppling over.

Pest and Disease Management: Peppers can be susceptible to pests such as aphids, spider mites, and whiteflies. Use organic pest control methods like neem oil, insecticidal soap, or beneficial insects to manage infestations. Ensure good air circulation around the plants to prevent fungal diseases, and avoid overhead watering to keep the foliage dry.

When to Harvest: Cayenne peppers are typically ready to harvest 70-80 days after transplanting, depending on growing conditions. The peppers will turn from green to a bright red color when fully ripe. You can harvest the peppers at any stage, but they will be hottest when fully red.

How to Harvest: Use scissors or pruning shears to cut the peppers from the plant, leaving a small portion of the stem attached to the fruit. Handle the peppers gently to avoid bruising. Harvest regularly to encourage continued fruit production.

Storing Fresh Peppers: Fresh Cayenne peppers can be stored in the refrigerator for up to 1-2 weeks. To store them longer, consider drying, freezing, or making hot sauce or chili powder. Dried peppers can be stored in an airtight container in a cool, dark place for several months.

Culinary Uses: Cayenne peppers are versatile and can be used in a variety of dishes. They are perfect for adding heat to sauces, soups, stews, salsas, and marinades. The peppers can also be dried and ground into cayenne powder, which is commonly used as a spice in cooking.
