Germination
7-14 daysTiny seedlings emerge with cotyledons (seed leaves). Plants are delicate and light-dependent.
Maintain 70-75°F soil temperature. Keep soil consistently moist. Provide bright light. Thin seedlings to proper spacing once true leaves appear.
Seedling
2-3 weeksFirst true leaves develop, plant grows to 2-3 inches. Purple-tinted stems begin appearing.
Gradually acclimate to outdoor conditions if starting indoors. Provide 12-14 hours of light daily. Water gently to avoid damping off.
Vegetative Growth
4-6 weeksPlant develops multiple stems and branches with characteristic dark purple coloring. Bushy foliage expands rapidly.
Pinch off growing tips regularly to encourage bushiness and delay flowering. Feed with balanced fertilizer every 3-4 weeks. Maintain consistent moisture.
Flowering
3-4 weeksSmall white to pale pink flowers appear in terminal spikes above the foliage. Aromatic intensity increases.
Harvest leaves before or as flowers appear to maximize flavor. Deadhead flowers if you want to extend leaf production. Allow some flowers for seed production if desired.
Seed Production & Maturity
3-4 weeksFlowers develop into small seeds enclosed in tiny capsules. Plant may begin to decline after heavy flowering.
Allow flowers to remain on plant if collecting seeds. Harvest seed heads when brown and dry. Allow 3-4 weeks for full seed maturation before collecting.

Harvest Tips
Begin harvesting leaves when plant is 6-8 inches tall by pinching off top 2-3 leaf sets. Harvest in early morning after dew dries for maximum essential oil content. Continue harvesting regularly throughout growing season to promote bushiness and delay flowering. For fresh use, pick leaves as needed. For drying, harvest just before flowers open. Cut stems 1/4 inch above leaf nodes to encourage branching.
