Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout within 7-10 days. True leaves emerge within 2-3 weeks with characteristic triangular or arrow-shaped foliage.

Keep soil moist but not soggy. Thin seedlings to proper spacing once true leaves appear. Provide bright light to prevent leggy growth.

2

Vegetative Growth

3-4 weeks

Plant develops multiple stems and increasingly robust foliage. Leaves grow larger and more numerous with vibrant color intensification.

Pinch off top growth to encourage bushier plant. Water consistently. Apply light fertilizer every 2-3 weeks. Keep soil consistently moist.

3

Baby Leaf Harvest

Ongoing from week 3-4

Young tender leaves are ready for picking. Plant has 4-8 true leaves and is lush but not yet mature.

Begin harvesting outer leaves as soon as they reach desired size (2-4 inches). This encourages continued leaf production and delays bolting.

4

Mature Growth & Full Harvest

Weeks 5-8

Plant reaches full height (2-4 feet depending on variety) with abundant foliage. Leaves are larger, more developed, and intensely colored.

Continue harvesting outer leaves regularly to extend season. Watch for flowering spikes. Water deeply during hot spells to slow bolting.

5

Bolting & End of Season

Week 8 onward

Plant produces tall flowering spikes with inconspicuous flowers. Foliage becomes tougher and flavor may become bitter.

Once bolting is evident, remove entire plant or continue harvesting lower leaves. Allow one plant to flower and go to seed for next season if desired.

Harvest Tips

Begin harvesting baby leaves when plant has 4-6 true leaves (20-30 days), picking outer leaves regularly to encourage bushy growth and extend the season. Harvest in the morning when leaves are crisp and full of moisture. For full-sized leaves, wait until plant reaches 12+ inches tall. Continue regular harvesting to prevent bolting. Flavor is best in cool weather; harvest before hot spells hit. Cut leaves at the base or pinch from the top. Most productive in spring and fall.

Fun Facts
