Germination & Seedling
2-3 weeksTiny seedlings emerge with initial small oval leaves. Growth is slow initially.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing after 2-3 weeks.
Vegetative Growth
4-8 weeksBasal rosette expands with multiple large, ribbed oval leaves growing close to the ground. Leaves are deep green with prominent parallel veins.
Water regularly, maintain consistent moisture. Remove any competing weeds. Mulch around base to retain moisture and suppress weeds.
Mature Foliage
Ongoing, 2+ monthsFull rosette of large, harvestable leaves (4-8 inches long) with dense foliage. Plant is established and vigorous.
Begin selective leaf harvesting. Ensure adequate water during hot weather. Apply mulch if growing in poor soil.
Flowering
4-8 weeksTall, thin flower spikes (6-12 inches) emerge from center of rosette with densely packed tiny greenish-white flowers arranged in cylindrical clusters.
Flowers are secondary to leaf production. Allow some flowers to mature for seed collection if desired, or remove to encourage continued leaf production.
Seed Production & Harvest
4-6 weeksFlowers develop into small capsules containing numerous tiny black seeds. Seeds mature and dry on the plant.
Allow seed heads to fully dry on plant. Collect seed heads before they shatter and disperse seeds. Dry completely before storage.

Harvest Tips
Begin harvesting outer leaves when plant is 2-3 months old by pinching or cutting them close to the base. Harvest regularly to encourage continued leaf production. For medicinal use, harvest leaves in early morning after dew dries. Leaves are best harvested before flowering for optimal potency. Can harvest continuously through growing season; perennial plants will regenerate. For culinary use, younger, tender leaves are preferred. Remove flower spikes if leaf production is the goal.
