Hot Pepper Seeds,
Cayenne Long Thin

Start Cayenne Long Thin seeds indoors early, about 8–12 weeks before the last expected frost, for a head start in cooler climates. Once temperatures consistently stay above 65 F at night, seedlings can be transplanted outdoors. These plants prefer a hot climate, so wait until there’s no chance of frost before moving them outside​.

Sow seeds 1/4 inch deep in seed-starting mix, keeping them in warm conditions. Once seedlings develop several sets of leaves, transplant them outdoors, spacing them 14-18 inches apart in full sun. In containers, a 2-gallon pot is ideal, and bottom-watering can prevent overwatering issues. Enrich the soil with compost for an extra nutrient boost, as these peppers thrive in fertile soil​.

Cayenne peppers need 8-12 hours of sunlight daily and grow best in well-draining, slightly acidic soil. Water deeply but infrequently, allowing the top 1–2 inches of soil to dry out between waterings to avoid root rot. Mulch around the plants to help retain moisture, especially in hotter climates. Fertilize with a balanced fertilizer, but reduce nitrogen once plants start flowering to encourage more fruit production​.
