Growth Stages

1

Seedling

1-2 weeks

Tiny seedlings emerge with cotyledons (seed leaves) and develop first true leaves within 5-7 days.

Keep soil consistently moist. Provide bright light. Thin seedlings to proper spacing once they develop true leaves.

2

Vegetative Growth

2-3 weeks

Plant develops multiple stems and a bushy appearance with increasingly larger, tender green leaves.

Water regularly, maintain consistent moisture. Fertilize every 2 weeks with balanced fertilizer or compost tea. Pinch growing tips to encourage bushiness.

3

Leaf Production

Ongoing, 3-4+ weeks

Plant reaches harvestable size with abundant tender leaves and young stems; continuous leaf production occurs.

Begin harvesting outer leaves regularly to encourage new growth. Maintain consistent watering and nutrition. Harvest frequently for tender leaves.

4

Bolting/Flowering

6-8 weeks

If left unharvested, plant develops flower spikes and seeds; leaves become tougher and less palatable.

For continuous leaf harvest, pinch off flower buds as they appear. If allowing to seed, let mature and dry for seed collection.

Harvest Tips

Begin harvesting leaves 30-40 days after planting when plants reach 6-8 inches tall. Harvest outer leaves and tender stem tips regularly to encourage bushiness and prevent bolting. Pinch off top 2-3 inches of stems for maximum leaf tenderness. Best harvested in early morning. Young leaves are most tender; harvest before plants flower. Can harvest continuously for 2-3 months with proper care.
