Soil, care & harvest

Prepare rich, well-draining soil with a pH between 6.0 and 7.0 to ensure healthy root development. As a warm-season crop, you must start seeds indoors only after the last spring frost date when soil temperatures are consistently warm. Sow seeds about one-quarter inch deep; they typically germinate in ten to fourteen days under proper warmth.

Space plants ten to twelve inches apart to maintain their compact habit and allow airflow. While these peppers generally do not require staking, provide support if vines become top-heavy with fruit. Water consistently to provide one inch per week, ensuring moisture levels remain steady for vibrant foliage. Apply mulch around the base and feed regularly during the growing season.

Watch for aphids, spider mites, and whiteflies, which can be managed by inspecting leaves frequently and using insecticidal soap if infestations occur. Diseases are rare in container culture, but good air circulation helps prevent issues. Harvest the peppers sixty to seventy days after transplanting when they reach full size and desired color.
