Belstar Organic Hybrid Broccoli

Belstar Organic Hybrid item #04914


Broccoli is a popular, delicious, and nutritious cool season vegetable. It is available in both standard large-headed types and "sprouting" forms with small heads and long, tender stems. Both forms are excellent eaten raw, steamed, in soups, and stir fried. Broccoli can be grown for both spring and fall harvest.

How to Plant

Sow seed indoors 6 to 8 weeks before the last frost in sterile starting mix kept at 70-76ºF. Expect germination in 10-17 days. For fall harvest, sow seed indoors in summer and plant outdoors in late summer to early fall. Cover seed with about ¼ inch of soil. Transplant to a larger pot when there are 2 sets of true leaves. Transplant seedlings in the garden 1 to 2 inches deeper than when growing in pots.

Broccoli is a cool season crop and can planted outdoors up to 1 month prior to last frost, but benefits from being hardened off before planting. Space plants 12 to 18 inches apart with 18 to 24 inches between rows. Seed packets contain a generous count of 150 seeds, unless otherwise noted.


Plant in full sun and well-drained soil. Harvest large-headed types when heads reach a good size and before buds open. A second flush of smaller secondary heads will form after the main head is harvested. Sprouting or broccolini types continue to produce over a long season after the main stem is harvested. Broccoli benefits from mulching to help keep the soil moist and cool.

Fertilizer Recommendations

Broccoli is a heavy feeder that benefits from regular fertilization. Use full rates of AlgoPlus All-Purpose Liquid Fertilizer 6-6-6 or Neptune Fish & Seaweed Fertilizer 2-3-1.

Common Problems

Usually one of the easiest of the crucifers to grow and not seriously troubled with pests or diseases. Aphids, caterpillars, flea beetles, slugs, whitefly, and leaf spot are occasional problems. In extremely hot weather, broccoli heads may be loose and flower early.
