Seedling
2-3 weeksTiny seedlings with 2 cotyledons emerge within 5-10 days; first true leaves appear shortly after.
Keep soil warm (70-75°F) and evenly moist. Provide bright light to prevent leggy growth. Thin seedlings to prevent overcrowding.
Vegetative Growth
4-6 weeksPlant develops multiple sets of opposite-paired leaves; stems become woody and sturdy. Bushy, compact growth with lush green foliage.
Pinch off flower buds to encourage leaf production. Remove top 1/4 of stems regularly to promote bushiness. Fertilize every 2-3 weeks with balanced fertilizer.
Flowering
ongoing if not pinchedDelicate lavender, pink, or white flower spikes form at branch tips; flowers attract pollinators.
Continue pinching off flowers if you want to maximize leaf production. Allow some flowers to remain if you want seed production or wish to attract beneficial insects.
Seed Production
2-3 weeksFlowers mature into seed capsules; foliage quality declines as energy shifts to seed development.
Allow flowering to proceed if collecting seeds. Cut and dry entire flower heads over paper to collect mature seeds.
Decline
final 2-4 weeks before frostPlant becomes woody, less productive, and more prone to disease as season progresses or temperatures cool.
Replant with fresh seedlings in mid-summer for fall harvest. Frost kills basil at 50°F; harvest before first frost.

Harvest Tips
Begin harvesting when plant has 6-8 leaves (3-4 weeks after transplanting). Pinch off top 1/4 inch of stems regularly to encourage bushiness. Harvest in morning after dew dries for best flavor. Remove flower buds promptly to extend leaf production. Continue harvesting throughout season; basil is more productive when harvested regularly. Cut stems just above leaf nodes to promote branching.
Fun Facts
