General Care and Maintenance
Watering and Fertilization: Broccoli needs regular watering to stay healthy, particularly during dry periods. Water at the base of the plants and use a balanced vegetable fertilizer to promote strong growth.
Pest and Disease Management: Keep an eye out for pests such as aphids and cabbage worms. Use row covers and organic pest control methods as needed. Practice crop rotation and clear away plant debris to minimize disease risk.
Harvesting Broccoli: Harvest the heads when they are firm and tightly closed. Cut the main head with part of the stem, and you may get additional smaller side shoots from the plant for further harvest.
