Plant Needs
Sunlight
Full sun to partial shade; requires at least 6 hours of direct sun for optimal bud development
Watering
Keep soil consistently moist but not waterlogged; avoid drought stress during bud formation
Temperature
Tolerates light frost (improves bud flavor); optimal growth at 10–18°C; bolts in temperatures above 25°C
Characteristics
- Leaf: Glaucous blue-green, oblong to lanceolate leaves forming a basal rosette
- Flower: Small four-petaled yellow cruciform flowers on tall bolting stems
- Stem: Thick rigid upright stem bearing dense axillary Brussels sprout buds
- Buds: Round cabbage-like buds (1–4 cm diameter) clustered along upper stem
Care Guide
Watering
Maintain even soil moisture; mulch to reduce evaporation
Fertilization
Side-dress with compost every 3 weeks during active growth. Avoid high-nitrogen fertilizers that promote leaf growth over bud development
Banana peel compost tea：Fully compost banana peels; dilute 1:20 for root drench to support bud formation and overall plant healthPruning
- Remove lower yellowing leaves to improve airflow and light penetration to developing buds
- Pinch off top stem growth 3 weeks before first frost to encourage uniform bud ripening
- Remove bolting stems if not saving seeds to redirect energy to bud production
- Thin overcrowded seedlings to 30–45 cm spacing at transplant to reduce competition
