Growing Tips

  • 1Plant Brussels sprouts in a spot with full sun and well-drained, fertile soil.
  • 2Water consistently to keep the soil moist but not waterlogged, especially during dry spells.
  • 3Space plants about 18-24 inches apart to allow for good air circulation, which helps prevent diseases.
  • 4Keep an eye out for pests like aphids and cabbage worms, and use row covers or natural predators to manage them.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from your Brussels Sprouts plant is a rewarding and simple process that any new grower can master! Allow your healthiest plants to flower and form seed pods, which look like small, thin beans. Once the pods turn brown and dry on the plant, gently snip them off and place them in a paper bag to finish drying. After a week or so, simply crush the pods to release the seeds. Store your seeds in a cool, dry place in a labeled envelope or jar, and they’ll be ready for planting next season—just imagine the satisfaction of growing your next crop from seeds you saved yourself!
