Seed germination
5-10 daysSeeds germinate on the soil surface, developing tiny seedlings with cotyledons visible within 5-10 days.
Keep soil warm (70-75°F) and consistently moist. Provide bright light or grow lights. Don't cover seeds as they need light to germinate.
Seedling to Young Plant
2-3 weeksFirst true leaves appear, plant develops 2-3 sets of leaves and grows to 2-3 inches tall.
Thin seedlings to 2-inch spacing if direct sown. Provide bright light to prevent legginess. Begin fertilizing weakly once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops 6-8 inches of height with multiple leaf sets; full lime aroma develops. Bushy growth with dense foliage.
Pinch off the terminal growing tip to encourage branching and bushier growth. Remove flower buds if you want to extend the vegetative, leafy stage. Water consistently.
Flowering
4-8 weeks (ongoing if not pinched)Small white, pink, or purple flowers appear on spikes at stem tips, plant reaches mature size (12-18 inches).
Pinch off flowers to redirect energy to leaf production and prolong harvest window. Allow some flowers if you want seeds or for pollinators. Aroma intensity may concentrate in flowers.
Maturity and Decline
Until frost or plant exhaustionPlant continues flowering; leaves may become slightly less tender and more woody if left unpruned. Plant begins setting seed.
Continue harvesting leaves to stimulate new growth. Pull plant before hard frost or as productivity declines. In warm zones, may persist into next season.

Harvest Tips
Begin pinching leaves when plant is 6 inches tall, harvesting from the top down to encourage branching. Harvest in the morning after dew dries for maximum aroma and flavor. Pinch off flower buds to extend leaf production. Continuous harvesting of small amounts promotes bushier growth. For bulk harvest, cut stems 1/3 of the way down. Never remove more than 1/3 of the plant at once.
Fun Facts
