Marte Brussels Sprouts
Plant seeds 1⁄4-1⁄2 inches deep. Transplant or thin small plants to 15-18 inches apart in rows 32-36 inches apart. Transplants can be started in April for May planting. Transplant after 4-6 weeks. Use a starter fertilizer, soaking the root ball thoroughly prior to transplanting. Direct seed in late spring, as seedlings can tolerate a light frost. Brussels Sprouts can be direct seeded up until mid-late June for a continuous harvest. Soil temperature should be 21-26 degrees C for optimal germination in 4-7 days.
Brussels Spouts prefer full sun, but will tolerate part shade. Prepare a rich, loose soil that holds moisture well and has pH level of 6.0-6.5. Brussels Sprouts are heavy feeders and will also benefit from applications of boron, calcium and magnesium, particularly during the early stages of growth.
