Growth Stages
Seedling
1-2 weeksTiny seedlings with first true leaves emerging; delicate appearance with minimal red coloration
Keep soil consistently moist; provide bright light; thin seedlings to proper spacing once first true leaves appear
Vegetative Growth
2-3 weeksPlant develops multiple stems and leaves; red coloration becomes more prominent; reaches 6-12 inches tall
Water regularly; apply balanced fertilizer every 2-3 weeks; remove any flower buds if focusing on leaf production
Leaf Production Peak
3-4 weeksFull-sized leaves with deep red veining; plant reaches 12-24 inches; dense foliage forms
Begin regular harvesting of outer leaves to encourage continued growth; maintain consistent moisture and nutrition
Flowering
2-3 weeksTerminal flower spikes develop; plant may grow taller (up to 3-4 feet); flowering indicates energy shift from leaves to reproduction
Harvest leaves before heavy flowering for best tenderness; can deadhead to prolong leaf production
Seed Production
3-4 weeksFlower spikes mature into seed heads; plant becomes coarser; production efficiency declines
Allow to mature if saving seeds; otherwise, pull plant and replant for continuous harvest

Harvest Tips
Begin harvesting tender leaves when plant reaches 6-8 inches tall by pinching off top growth or cutting outer leaves with scissors. Regular harvesting (every 3-4 days) encourages bushier growth and tender leaves. Harvest in early morning for best quality. Can harvest continuously for 6-8 weeks; entire plant can be cut if desired. Younger leaves are more tender than mature ones.
Fun Facts
