Vegetative Growth
2-3 weeksPlant develops characteristic frilly, deeply lobed leaves. Foliage becomes darker green and more ornamental with each passing week.
Maintain consistent moisture. Apply balanced fertilizer at 2-3 week intervals. Mulch to suppress weeds and maintain soil temperature.
Mature Greens
1-2 weeksFull rosette of frilly, textured leaves 6-12 inches tall with tender, mild flavor. Plant is ready for leaf harvesting.
Begin harvesting outer leaves regularly to encourage continued growth. Water consistently; avoid letting soil dry out.
Flowering/Bolting

Harvest Tips
Begin harvesting outer leaves when plants are 4-6 inches tall for tender baby greens; mature harvesting at 40-50 days. Cut leaves at soil level or pinch off individual outer leaves to allow continued center growth. Morning harvest yields crispest leaves. Can be cut entirely at soil level for regrowth, or harvested leaf-by-leaf. Best flavor when tender; harvest before bolting in warm weather.
