Seedling
7-14 daysTiny cotyledons emerge with thin stems. First true leaves appear after 7-10 days.
Keep soil consistently moist. Thin seedlings to proper spacing when 2-3 inches tall. Avoid direct sun stress with shade cloth if needed.
Early Vegetative
2-3 weeksTrue oak-shaped leaves begin to form. Plant develops a rosette pattern of 6-8 leaves.
Maintain consistent moisture and cool temperatures (60-70°F ideal). Apply balanced fertilizer every 2-3 weeks. Remove any yellowing outer leaves.
Mid-Vegetative
2-3 weeksDense rosette of deeply lobed leaves develops; plant reaches 8-12 inches diameter. Leaves are increasingly tender and full-flavored.
Continue regular watering. Mulch around base to retain moisture and cool soil. Monitor for pests. Begin light harvests of outer leaves.
Mature Harvest
3-4 weeksFull-sized rosette with abundant tender, lobed leaves ready for harvest. Plant maintains productivity with proper leaf removal.
Harvest outer leaves from bottom up 2-3 times per week. Keep plant consistently watered. In hot weather (above 75°F), plant will begin to bolt and turn bitter.
Bolting
1-2 weeks onwardPlant sends up central flower stalk; leaves become smaller, tougher, and distinctly bitter. Not recommended for harvest at this stage.
Remove bolting plants or allow to set seed for next season. Plant succession crops for continuous harvest.

Harvest Tips
Begin harvesting outer leaves when plant is 6-8 inches tall, about 30-45 days from transplanting. Pinch or cut leaves 1-2 inches above soil line from the outside of the rosette, working inward. Harvest in early morning for crispest texture. Regular harvesting encourages continued leaf production. Can harvest until plant bolts. For whole-plant harvest, cut at soil level when fully mature.
