Seedling
7-10 daysFirst true leaves appear with characteristic feathery texture; seedlings are delicate and bright green
Thin seedlings to spacing if overcrowded; maintain consistent moisture and cool temperatures; provide good air circulation to prevent fungal issues
Vegetative Growth
10-20 daysLeaves expand and develop the distinctive fine, lacy foliage; plant grows rapidly with multiple leaf stems
Water regularly; side-dress with compost or balanced fertilizer if desired; keep area weed-free. Can harvest outer leaves at this stage for baby greens
Harvest Ready
Ongoing; 2-4 weeks of harvest windowPlant reaches 6-12 inches tall with full, feathery leaves ready for cutting; does not form a tight head

Harvest Tips
Begin harvesting baby greens at 20-25 days when plants are 4-6 inches tall by cutting outer leaves, or harvest the entire plant at soil level. For continuous supply, pick leaves from the outside first. Harvest in the morning for best crispness and flavor. Early morning harvest captures peak tenderness before heat stress. Can be harvested repeatedly by cutting 1-2 inches above soil for regrowth.
