Seedling
2-3 weeksTiny cotyledons emerge, followed by first true leaves; plant is delicate and light green
Keep soil warm (70-75°F) and consistently moist. Provide bright light or grow lights. Thin seedlings to prevent overcrowding.
Vegetative Growth
3-4 weeksPlant develops bushy, compact form with multiple stems and increasingly abundant small leaves; no flowers present
Pinch off growing tips regularly to encourage bushier growth. Ensure adequate light to prevent leggy growth. Begin regular harvesting of leaf tips.
Pre-flowering
2-3 weeksPlant reaches mature compact size with dense foliage; flower buds begin forming at stem tips
Pinch out flower buds promptly to extend leaf production and prevent plant from becoming woody. Continue regular harvesting.
Flowering
3-6 weeksSmall white, pink, or purple flowers appear in terminal spikes if not removed; leaves may become slightly tougher
Remove flower spikes to redirect energy into leaf production. If allowing flowers for seed saving, reduce harvesting to support reproduction.
Decline/End of Season
Varies with seasonPlant becomes woody, less productive; leaves smaller and flavor diminishes. Growth slows significantly in fall or approaching frost
In cool climates, plant will decline with first frost. Collect seeds before frost if desired. Replace with new plantings for continuous supply.

Harvest Tips
Begin harvesting when plant has 6-8 true leaves (pinch off top 1/4 inch of stems). Harvest regularly to encourage bushiness—remove leaves from the top down. Morning harvest after dew dries yields best flavor. Pick flowers before they fully open. Continuous harvesting extends productive season. For maximum flavor, harvest before midday heat.
