Germination
5-10 daysSeeds sprout with cotyledons (seed leaves) emerging, showing pale green color
Keep soil consistently moist; maintain temperature of 70-75°F; provide bright light immediately after germination to prevent leggy growth
Seedling
2-3 weeksFirst true leaves appear; plant develops stronger stem and root system; 2-4 true leaves visible
Provide bright light or grow lights; thin seedlings to proper spacing; avoid overwatering which causes damping off
Vegetative Growth
3-4 weeksPlant develops multiple stems and increasingly larger leaves; becomes bushy and full; no flowers yet
Pinch off flower buds and top 1/4 inch of stems regularly to encourage bushiness; fertilize lightly every 2-3 weeks; maintain warm temperatures
Flowering
2-4 weeks onwardSmall white or pale purple flower spikes form at stem tips; leaves may become slightly smaller and less flavorful
Pinch off flower buds promptly to extend leaf harvest and maintain leaf quality; if allowing flowers, deadhead spent blooms regularly
Decline
8-12 weeks from plantingPlant growth slows; foliage becomes sparse; stem becomes woody; flavor diminishes
Replace plant with fresh seedlings in midsummer for continuous harvest; can compost spent plants; collect seeds from late flowers if desired
