Seedling
2-3 weeksTiny leaves with rounded cotyledons emerge; plant is delicate and light green
Keep soil consistently moist; provide 12-14 hours of light daily; maintain 70-75°F temperature; thin seedlings to proper spacing once true leaves appear
Vegetative Growth
3-4 weeksPlant develops sturdy stems and increasingly larger leaves; bushy growth pattern emerges
Pinch out growing tips regularly to encourage bushiness; maintain consistent moisture and warmth; fertilize every 2-3 weeks with balanced fertilizer; ensure 6+ hours of sunlight
Leaf Production (Harvestable)
4-8 weeks or morePlant reaches 8-12 inches tall with abundant leaves ready for picking; foliage is full and aromatic
Begin regular harvesting by pinching off top leaves and stem tips; this stimulates more branching and delays flowering; continue fertilizing; water consistently
Flowering
2-4 weeks (can be delayed by deadheading)Small white or pale purple flower buds form on stem tips; leaves may become slightly tougher and less flavorful
Pinch off flower buds immediately to extend leaf production and maintain tenderness; if you allow flowering, reduce harvesting to prevent plant stress
End of Season/Decline
1-2 weeks or ongoing declinePlant bolts fully, flowers mature, growth slows as temperatures drop or plant energy goes to seed
In fall, cover with row cloth in cool zones to extend season; water less frequently; pull plant and compost as productivity declines
Common Pests
-
Hand-pick beetles in early morning; use row covers in spring; spray neem oil or insecticidal soap if infestation is heavy
-
Increase humidity by misting leaves; spray with water to dislodge; use neem oil or insecticidal soap; isolate infected plants
-
Use yellow sticky traps; spray insecticidal soap or neem oil; improve air circulation; remove heavily infested leaves
-
Spray with strong water stream; use insecticidal soap; apply neem oil; introduce ladybugs or lacewings
-
Improve air circulation; avoid overhead watering; spray with sulfur or baking soda solution (1 tbsp per gallon water); remove affected leaves

Harvest Tips
Begin harvesting when plant is 6-8 inches tall by pinching off the top 2-3 sets of leaves; continue pinching throughout the growing season to promote bushiness and prevent flowering. Harvest in the morning after dew dries for best flavor and aroma. Remove flowers immediately to extend leaf production. Classic basil will produce prolifically for 2-3 months in ideal conditions.
