Cascabella Pepper

Start Cascabella pepper seeds indoors 6 to 8 weeks before your last spring frost, sowing seeds at a depth of 1/4 inch in warm, moist seed-starting mix. Maintain soil temperatures between 70 and 85 degrees Fahrenheit for reliable germination. Transplant seedlings into larger containers once they develop their second set of true leaves, and harden them off gradually over 7 to 10 days before moving them outdoors.

Transplant hardened-off seedlings outdoors after all danger of frost has passed and soil temperatures have reached at least 60 degrees Fahrenheit, though 65 to 70 degrees is ideal for more vigorous growth. Space plants 18 inches apart in rows 36 inches apart, whether in garden beds, raised beds, or in greenhouse structures. Handle seedlings gently, as pepper transplants can be sensitive to root disturbance.

Cascabella peppers are ready to harvest 70 to 79 days after transplanting, and they're at their peak when the skin develops a bright yellow color and feels waxy to the touch. Pick peppers at this yellow stage if you intend to pickle them with turmeric, as this is when they're most visually striking and their flavor profile is most characteristic. You can also allow peppers to mature further on the plant if desired, though the yellow stage is when they're traditionally harvested. Use a clean knife or pruners to cut peppers from the stem rather than pulling, which can damage the plant.

Cascabella peppers have an upright growth habit and generally need minimal pruning. You may remove any lower leaves that touch the soil to improve air circulation and reduce disease pressure, and pinching out the central growing tip when plants are young can encourage bushier branching and more flower production. Avoid heavy pruning once flowering begins, as it will reduce your harvest.
