Broccoli is a nutrient-rich vegetable which can be used in a variety of ways. It can be eaten fresh, lightly sautéed or used in stir fry, soup and pasta or rice-based entrees. Wait until frost-free weather has arrived before transplanting spring seedlings in the garden. Be sure to harden plants off by gradually exposing broccoli seedlings to direct sunlight and wind. Try growing broccoli in an organic, rich soil and fertilize seedlings and young transplants to maintain steady growth. Use a balanced fertilizer, as too much nitrogen promotes excessive leaf growth. Potassium and phosphorus encourage bloom development. Water regularly since broccoli grows best in moist, but not soggy, soils. Mulch to control weeds and retain soil moisture levels. To harvest, use a sharp knife to remove the central flower head. Leaving the broccoli plant in the ground encourages side shoots (flower heads) to develop. Although smaller than the central head, these side shoots allow gardeners to continue harvesting broccoli for a longer period of time.
