Planting & Care

Start seeds indoors 6-8 weeks before the last frost date, sowing ¼ inch deep in seed-starting mix. Keep soil moist and maintain temperatures around 65-75°F for optimal germination, which typically occurs in 7-14 days. Harden off seedlings before transplanting outdoors after the danger of frost has passed. For fall crops, sow seeds directly in midsummer.

Broccoli requires consistent moisture and regular feeding for best growth. Mulch to retain soil moisture and suppress weeds. Harvest the main head when buds are tight and before flowers open; side shoots will continue to produce smaller heads for weeks. Watch for common pests like cabbage worms and aphids, and practice crop rotation to maintain soil health.
