Germination & Seedling
2-3 weeksSeeds sprout within 5-10 days; seedlings develop cotyledons and first true leaves
Keep soil consistently warm (70-75°F). Provide bright light immediately after sprouting. Water gently to avoid damping off.
Vegetative Growth
3-4 weeksPlant develops multiple stems and increasingly dense foliage; leaves grow fuller with characteristic orange-scented aroma
Pinch off top growth when plant reaches 6 inches to encourage bushiness. Feed with balanced fertilizer every 2-3 weeks. Keep consistently moist.
Pre-flowering
2-3 weeksPlant reaches mature size; leaf production continues but flowering buds begin to form at branch tips
Continue pinching off flower buds to extend leaf production. Harvest regularly to maintain vegetative growth and prevent bolting.
Flowering
4-6 weeks (ongoing if not removed)Small white or pale purple flowers appear on terminal spikes; flowering can reduce leaf flavor intensity
Pinch off flower buds to maintain leaf quality and encourage continued foliage production. If allowing flowering for seed, reduce nitrogen fertilizer.
Decline & End of Season
Variable, 1-2 months before frost or natural declinePlant begins to slow growth; leaves may become less tender; plant weakens as it transitions to seed production
In cool climates, plant dies back with frost. In warm zones, can be overwintered. Pull plant if productivity drops significantly.
Common Pests

Harvest Tips
Begin harvesting when plant reaches 6 inches tall by pinching off top leaves and stem tips. Harvest regularly (2-3 times per week) to encourage bushiness and prevent flowering. Pick leaves in the morning after dew dries for best flavor. Remove upper leaves first; the plant will branch at the pinch point. Can be harvested continuously until frost or plant decline. Leaves are most flavorful just before flowering.
