Seedling
7-10 daysTiny cotyledons emerge, followed by first true leaves. Plant is delicate and pale green.
Keep soil moist, maintain warm temperatures (70-75°F), provide bright indirect light or gentle grow light. Thin seedlings to proper spacing. Avoid overwatering which causes damping off.
Vegetative Growth
10-20 daysPlant develops multiple sets of true leaves, becoming bushier and more robust. Stems strengthen and thicken.
Pinch top 1-2 inches when plant reaches 6 inches tall to encourage branching and compact shape. Ensure 6-8+ hours of full sun daily. Begin light fertilizing every 2-3 weeks with balanced fertilizer.
Pre-flowering
Ongoing until flowering begins or harvest desiredPlant reaches mature height (12-18 inches for Green Spell), becomes very dense and compact with abundant foliage.
Continue pinching flower buds as they appear to extend leafy vegetative growth. Maintain consistent watering and full sun. Monitor for pests.
Flowering
Variable; can be prevented with regular pinchingSmall white, purple, or pink flower spikes emerge from leaf nodes. Flowering can reduce leaf quality and flavor.
Pinch off flowers as they appear to prolong productive leaf growth and maintain superior flavor. If allowing flowers to bloom for bees, expect some reduction in leaf tenderness.
Harvest & Maintenance
4-8 weeks typically, until frost or plant senescencePlant is actively producing harvestable foliage; proper harvesting encourages further branching and bushiness.
Harvest leaves regularly from top, pinching off 1/4 to 1/3 of growth. This stimulates more branching. Continue pinching flowers. Keep fertilizing every 2-3 weeks. Water consistently.

Harvest Tips
Begin harvesting when plant is 6-8 inches tall by pinching off top 1-2 inches of stems. Always pinch from the top to encourage bushier growth. Harvest regularly (2-3 times per week) to maintain tenderness and prevent flowering. Leaves are most flavorful in the morning after dew dries. Cut just above a leaf node. For storage, harvest in the morning, rinse gently, and use fresh or freeze in oil/butter for preservation.
