General Care and Maintenance

Watering and Feeding: Broccoli requires consistent moisture, especially during dry spells. Water at the base to avoid wetting the leaves, and use a balanced vegetable fertilizer as needed.

Pest and Disease Management: Be aware of pests like aphids and cabbage worms. Use floating row covers and organic pesticides if necessary. Rotate crops and remove plant debris to prevent disease.

Harvesting Broccoli: Harvest the heads when they are firm and tight, before the flowers start to open. Cut the main head with part of the stem attached, and the plant will often produce smaller side shoots for a continued harvest.
