Germination
1-2 weeksSeeds sprout and tiny seedlings emerge with first true leaves appearing within 10-14 days.
Keep soil consistently moist but not waterlogged. Maintain temperatures between 60-70°F for best germination. Provide bright indirect light once sprouted.
Seedling/Young Plant
2-4 weeksPlants develop several true leaves and form a small rosette of delicate, arrow-shaped foliage.
Thin seedlings to 12 inches apart. Begin fertilizing lightly with balanced fertilizer. Protect from strong winds. Ensure consistent moisture.
Vegetative Growth
Ongoing; most productive 4-8 weeks after plantingPlant expands its rosette with increasing numbers of tender, pale green arrow-shaped leaves arising from the base.
Pinch off any flower buds to encourage leaf production. Regular harvesting promotes bushier growth. Maintain consistent moisture and moderate feeding.
Flowering
3-6 weeks (spring to early summer)Small, reddish or greenish flower spikes emerge on tall stalks above the foliage in late spring to early summer.
Remove flower stalks promptly to extend leaf production and prevent the plant from going to seed. If allowing seed production, cease harvesting.
Dormancy (Winter)
3-4 months (varies by climate)Plant dies back in severe cold or reduces growth dramatically; may retain some foliage in mild winters.
Reduce watering significantly. Mulch around base to protect roots in zone 3-5. Plant will regrow from roots in spring.

Harvest Tips
Begin harvesting leaves when plant is 4-6 inches tall, typically 30-45 days after planting. Pinch or cut outer leaves regularly, which encourages more growth. Harvest in the morning after dew dries for best flavor and texture. Remove flower stalks before they set seed to prolong leaf production. Continue harvesting throughout growing season; plant is most tender and flavorful in cool weather (spring and fall).
