Start seeds indoors 6-8 weeks before your last spring frost. Use a warm seed starting mix and maintain soil temperature between 70-85°F for optimal germination. Keep the soil consistently moist but not waterlogged, and provide bright light once seedlings emerge.
Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant outdoors after the last frost date when soil temperature has reached at least 60°F, preferably warmer. Space plants 18 inches apart in full sun locations with well-draining soil adjusted to pH 6.0-6.8.
Pick peppers when they reach full size and desired ripeness, typically 80-90 days after transplanting. Manganji peppers can be harvested at the mature green stage or left to develop deeper color for sweeter flavor. Use clean pruning shears or a sharp knife to cut peppers from the plant rather than pulling, which can damage branches.
