Start seeds indoors 5 to 7 weeks before your transplant date, maintaining soil temperatures between 65 and 75 degrees Fahrenheit for reliable germination. Keep seedlings under bright light once sprouted and harden off for 7 to 10 days before moving outdoors, exposing them gradually to wind and direct sun.
Transplant seedlings outdoors when they have 4 to 6 true leaves and soil has warmed to at least 50 degrees Fahrenheit. Space plants 18 to 24 inches apart in rows 24 to 30 inches apart, taking care to bury the stem slightly deeper than it grew in the pot to promote sturdy root development. Kariba reaches harvest in 66 days from transplanting.
Harvest Kariba heads when they are firm, compact, and dark green, typically 66 days after transplanting. Cut the main head with 5 to 6 inches of stem using a sharp knife while the buds remain tightly clustered and before any open into yellow flowers. Side shoots will often develop after the main head is removed, extending your harvest window if conditions remain cool.
