Broccoli, Brussels Sprouts, Cabbage, and Cauliflower are all in the brassica family and as such have similar growing requirements and needs.  Typically planted into your garden between mid-August and early May.  Each of these varieties wants to be planted into a rich garden bed and have full access to the sun.  Before transplanting, prepare the soil, by digging and loosening the soil 8-10 inches deep and 12-18 inches in diameter.  Add to this zone, 6 cups of finished compost, 3 cups of Landscape Mix and 3 cups of worm castings.  Thoroughly incorporate the ingredients and then transplant the seedling.   For optimum growth, allow two feet of space per plant.   These plants want are continually growing and expanding and as such, need adequate moisture.  Water slowly and deeply once every 5-7 days during the growing season.  It is possible that you will not need to water during the winter months if we are having a cool, wet winter.
