Broccoli is usually green while cauliflower is white although there is green cauliflower. Broccoli florets are spread out while the cauliflowers are tightly bunched. The spacing depends on the variety, soil fertility and water availability. Mulching helps in keeping the soil moist hence maintaining the soil temperatures. The broccoli head should be harvested at a slant by cutting the stalk about 2-3cm below the head.
