Planting & Care

Start Calabrese broccoli seeds indoors 6 to 8 weeks before the last spring frost, or sow directly in the garden in late summer for a fall crop. Sow seeds about 1/4 to 1/2 inch deep in a seed-starting mix, keeping the soil consistently moist but not waterlogged. Germination typically occurs in 7 to 14 days at soil temperatures around 65 to 75°F. Once seedlings have two to three true leaves, harden them off and transplant into the garden.

Broccoli thrives in fertile soil with regular watering. Mulch around plants to retain moisture and suppress weeds. Fertilize lightly when plants begin to form heads. Harvest the central head while buds are tight and green, before they open into yellow flowers. After cutting the main head, continue watering and side shoots will develop for additional harvests. Watch for common pests like cabbage worms and use row covers or handpicking as needed.
