Appearance
Brussels sprouts grow on a tall, upright stem and can reach a height of two to three feet. The small, round leaf buds grow in a spiral pattern along the stem, with the largest buds at the bottom and the smallest at the top. The buds are typically one to two inches in diameter and are a bright green color. As the plant matures, the buds become more tightly packed and the lower leaves start to yellow and fall off. If left unharvested, the buds will continue to grow and eventually bloom into yellow flowers.

Water: Brussels sprouts require consistent moisture, so it is important to water them regularly. Keep the soil evenly moist, but not waterlogged.
Fertilization: Brussels sprouts are heavy feeders and require regular fertilization throughout the growing season. Use a balanced fertilizer every four to six weeks.
Soil: Brussels sprouts prefer well-drained, fertile soil with a pH between 6.0 and 7.5. Amend the soil with compost or aged manure before planting to improve soil fertility and texture.
Sunlight: Brussels sprouts prefer full sun, but can tolerate partial shade.
