How to grow…Brussels Sprouts

Our pre started plants did not do so good last year. The sprouts were very small. We’re hoping that our Nautic Organic Brussels Sprouts seeds turn out better this year.


  • Plant seeds ¼-½” deep. Transplant or thin small plants to 15-18″ apart in rows 32-36″ 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°C (70-80°F) for optimal germination in 4-7 days.


  • Brussells Sprouts prefers full sun, but will tolerate part shade. Prepare a rich, loose soil that holds moisture well and has a pH
    level of 6.0-6.5.
  • Brussels Sprout is a heavy feeder and will also benefit from applications of boron, calcium and magnesium, particularly during the early stages of growth.


  • To encourage development of the upper sprouts, pinch out the growing tip of the plant in late summer.
  • Harvest sprouts as needed from the bottom of the stalk when they are about 1-1½” in diameter.
  • The spouts will develop a sweeter flavour after a few light frosts.
