Gardeners with a short growing season will want to start seedlings inside and transplant with other warm crops like zucchini. In a warm climate, plant seeds directly in ground approximately 60-70 days before last frost date. Broccoli is a moderate to heavy feeder and would benefit from occasional feedings of manure tea. Keep evenly moist, especially while forming flower heads. Harvest before buds open.
