Seedling
1-2 weeksTiny leaves emerge with two cotyledons; plant is delicate and small

Maturity
1-2 weeksPlant reaches 6-12 inches tall with fully formed heads; white stalks are crisp and tender, leaves are dark green
Reduce nitrogen fertilizer to avoid excess leaf production. Harvest outer leaves or whole plant as needed. Can begin selective harvesting while plant is still growing.
Flowering/Bolting
