Planting & Care

Start Long Island Improved Brussels Sprouts seeds indoors 6 to 8 weeks before the last expected frost, or sow directly in the garden in late summer for a fall crop. Plant seeds about 1/4 to 1/2 inch deep in a seed-starting mix or prepared garden bed. Keep the soil evenly moist during germination, which typically occurs in 7 to 14 days at soil temperatures around 65 to 75°F. Once seedlings have several true leaves, harden them off and transplant to the garden, spacing plants 18 to 24 inches apart in rows 24 to 36 inches apart.

Brussels sprouts grow best in full sun with consistent watering and fertile, well-drained soil. Side-dress with compost or a balanced fertilizer during the growing season. As the plants mature, remove lower leaves to encourage stalk development and harvest sprouts from the bottom up when they are firm and about 1 to 1.5 inches across. A light frost can enhance flavor, so leave plants in the garden into cool weather for the best taste.
