Growth Stages
Seedling
3-4 weeksYoung plants with 2-4 true leaves, fragile and tender
Keep soil moist but not soggy. Provide 12-14 hours of bright light daily. Maintain 65-70°F temperatures. Thin seedlings if crowded.
Vegetative Growth
4-6 weeks after transplantingPlant develops 6-8 true leaves and strong root system. Growth is vigorous with lush foliage
Harden off gradually before transplanting outdoors. Plant out when 4-6 weeks old, spacing 18 inches apart. Apply balanced fertilizer every 2-3 weeks. Monitor for cabbage worms.
Stalk Development
4-6 weeksTall central stalk (2-3 feet) elongates with leaves spaced along the stem
Support plant if needed in windy locations. Remove lower leaves as sprouts develop below them. Continue consistent watering and fertilization. Watch for pest pressure.
Sprout Formation & Sizing
6-8 weeksAxillary buds swell into small, compact green heads (sprouts) along the stalk, beginning at bottom
Pinch off growing tip 4-6 weeks before first expected frost to redirect energy to sprouts. Remove yellow or damaged lower leaves. Apply nitrogen-based fertilizer if needed.
Harvest Ready
4-8 weeks of continuous harvestFirm, dark green sprouts 1-2 inches in diameter ready to pick from bottom upward

Harvest Tips
Begin harvesting when sprouts reach 1-1.5 inches in diameter, typically 90-110 days after transplant. Pick from the bottom of the stalk upward as sprouts mature.

Cut sprouts cleanly with a sharp knife, leaving the base of each sprout to allow secondary growth.
Fun Facts
- 🌱 Brussels sprouts are actually miniature cabbage heads that grow as buds along a central stalk, and the plant itself resembles a small tree.
- 🌱 The flavor of Brussels sprouts sweetens noticeably after exposure to frost, as cold temperatures trigger the conversion of starches to sugars for plant protection.
- 🌱 Brussels sprouts are named after Brussels, Belgium, where they became popular in the 16th century, though they likely originated in the Mediterranean region.
