Germination & Seedling
2-3 weeksSeeds sprout within 5-10 days, producing first true leaves. Seedlings are small and delicate with cotyledons followed by deeply lobed brassica leaves.
Keep soil moist. Thin seedlings to proper spacing when 2-3 inches tall. Protect from heavy rain or strong wind.
Vegetative Growth
2-4 weeksRapid leaf development with multiple lobed leaves emerging. Plant develops dense foliage and reaches 6-12 inches in height.
Maintain consistent moisture and steady nitrogen supply. Begin harvesting outer leaves when plant is 6-8 inches tall. Side-dress with compost if needed.
Full Canopy
3-6 weeksPlant reaches mature height of 12-18 inches with abundant thick, tender leaves ready for harvest. Foliage is dark green and vibrant.
Continue regular harvesting of outer leaves to encourage more production. Water regularly. Watch for bolting in hot weather.
Bolting (in warm weather)
Variable; occurs in late spring/summerPlant may produce a central flower stalk and small yellow flowers if temperatures exceed 75°F or days lengthen significantly.
Harvest remaining leaves before bolting occurs. Bolt-tolerant plants can still be eaten but leaves become tougher and slightly more bitter.
Harvest to End of Season
4-8 weeksContinuous harvesting phase where outer leaves are picked regularly while plant continues producing new growth from the center.
Cut outer leaves 2-3 inches above soil line. Never remove more than 1/3 of plant at once. Continue until first hard frost or bolting occurs.

Harvest Tips
Begin harvesting outer leaves when plant is 6-8 inches tall. Cut leaves 2-3 inches above the soil line using a sharp knife or by snapping off by hand. Harvest in early morning for best flavor and texture. Outer leaves are most tender; inner leaves will regenerate for continued harvests. Plant is best used fresh but can be lightly cooked. Most tender and flavorful before plant bolts or reaches 4-6 weeks of age.
