Suggested Cultivars Broccoli For good side shoot production after harvest of the main head, try Green Comet and Packman. Two other excellent cultivars for the home garden are Green Hornet and Premium Crop. Cauliflower Snow Crown, Snow King, Snowball 123, and Imperial 10-6 are good cultivars for the home garden.

Broccoli transplants may be set out in the garden as early as April 1. For a fall cauliflower crop, set out transplants on July 1. Broccoli may be spaced 18 inches apart in the row with 24 inches between rows. Cauliflower requires a little more room. Set cauliflower plants 24 inches apart in the row with 30 inches between rows.
