Soil: Brussels sprouts are heavy feeders and require nutrient-rich, calcareous, and well-drained soil. Work in plenty of compost or well-rotted manure before planting.
Watering: Keep the soil moist, especially during dry spells, to keep the sprouts firm.
Fertilizing: During the growing season, apply organic fertilizer or compost tea to provide the plant with sufficient nutrients.
Care: Regularly remove yellowed leaves to improve air circulation and prevent disease.

Harvest tips:

• Harvest from the bottom up once the florets feel firm.
