Germination & Seedling
2-3 weeksSeeds sprout in 5-10 days. Seedlings develop 2-4 true leaves and are delicate, with fine root systems.
Keep soil consistently moist. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once they have 2 true leaves. Maintain temperatures between 60-70°F.
Early Vegetative Growth
2-3 weeksPlant develops 4-8 true leaves and establishes a stronger root system. Petioles begin thickening slightly. Growth is rapid in cool conditions.
Water regularly and maintain even soil moisture. Begin light fertilizing with balanced or nitrogen-rich fertilizer every 2 weeks. Mulch around plants to retain moisture and suppress weeds.
Vegetative Expansion
2-3 weeksPlant grows substantially with multiple thick, white petioles and a rosette of glossy dark green leaves. The plant reaches 8-12 inches tall.
Continue consistent watering. Maintain soil fertility with regular feeding. Monitor for pests, especially flea beetles and cabbage moths. Provide afternoon shade in temperatures above 75°F to delay bolting.
Pre-Harvest Maturity
1-2 weeksPlant reaches full size with tender, succulent petioles and a tight rosette. Petioles are white and crisp, leaves are deep green and unblemished.
Reduce nitrogen to prevent excessive leafiness that reduces quality. Maintain consistent moisture to ensure tender texture. Check daily for pest damage. Harvest before any flower buds form.
Harvest & Decline
VariablePlant is ready to harvest at peak tenderness. If not harvested, plant begins to bolt, producing flower stalks and bitter compounds.
Harvest immediately when mature to ensure best flavor and texture. Cut at soil level or harvest outer leaves for continued production. Use immediately after harvest for best quality.
