Grow Capsicum annuum 'Cayennetta' (Pepper 'Cayennetta') for dependable, slender cayenne-type peppers on a compact plant that fits easily in beds, raised gardens, and containers.
Give it full sun for best flowering and fruit set. Plant outdoors after danger of frost has passed and nights are consistently warm. In containers, use a quality potting mix and a pot with drainage; in the ground, choose fertile, well-drained soil and enrich with compost if needed.
Keep moisture steady, especially once fruit begins to form. Water deeply when the top inch of soil dries, and mulch to reduce evaporation and keep roots cooler. A light feeding at planting and periodic feeding through the season helps maintain growth and production without pushing overly leafy plants at the expense of fruit.
At maturity this selection typically reaches about 20-24 inches tall with a similar spread. If branches become heavy with fruit, stake or cage lightly for support. Harvest peppers as they color and reach the size and heat you prefer; frequent picking encourages continued production. In very warm climates it can persist longer, but most gardeners treat it as a warm-season annual.
