Seedling
2-3 weeksTiny cotyledons emerge with minimal true leaves; delicate and light green.
Keep soil warm (70-75°F) and consistently moist. Provide bright light. Thin seedlings to appropriate spacing once first true leaves appear.
Vegetative
3-4 weeksPlant develops multiple true leaves and a bushy branching habit. Leaves are large, slightly wrinkled, and deep green.
Pinch out growing tips regularly to encourage bushiness and prevent flowering. Maintain consistent moisture and warmth. Feed with diluted balanced fertilizer every 2 weeks.
Pre-flowering
2-3 weeksPlant reaches mature size with dense foliage; flower buds begin to form at stem tips.
Pinch off flower buds as soon as they appear to extend the harvest period and maintain tender leaf quality. Continue regular watering and fertilizing.
Flowering
2-4 weeksSmall white or pale purple flowers appear in terminal clusters above the foliage.
Once flowering begins, the plant begins to decline in leaf quality. Pinch flowers off to encourage more leaf production, or allow flowering if collecting seeds.
Decline
VariablePlant becomes woody, leaves may taste more bitter, and flowering intensifies.
At this point, harvest the remaining leaves or remove the plant and start fresh with new seedlings. Genovese basil is typically grown as a single-season crop.

Harvest Tips
Begin harvesting leaves once the plant has at least 6-8 true leaves. Pinch off the top 1-2 inches of stems regularly to encourage bushiness. For best flavor, harvest in the early morning after dew dries. Remove entire stem sections rather than individual leaves. Never remove more than one-third of the plant at one time. Continue pinching off flower buds to extend the harvest season.
