Seedling
2-3 weeksSmall plants with 2-4 true leaves emerging, tender and delicate
Keep soil consistently moist. Provide bright, indirect light. Maintain 65-75°F for best germination. Thin seedlings to prevent crowding
Vegetative
4-8 weeksRapid leaf growth with expanding stems; plant becomes bushy and full. Foliage colors and patterns become distinct
Pinch growing tips every 2-3 weeks to encourage bushiness. Maintain consistent moisture and bright light. Begin diluted fertilizing every 2 weeks
Established Growth
Ongoing during growing seasonMature plant with dense foliage, ready for regular harvesting. Leaves are fully colored with characteristic texture and variegation
Continue regular pinching to maintain shape and promote branching. Harvest leaves frequently for culinary use. Fertilize every 2-3 weeks with balanced feed
Flowering
2-4 monthsSmall tubular flowers appear in terminal spikes, typically white, pink, blue, or purple depending on species
Pinch off flower buds if growing for foliage only, as flowering reduces leaf production. Allow flowers to develop if seed collection is desired
Senescence/Dormancy
3-4 monthsPlant growth slows significantly in fall and winter; older leaves may yellow and drop
Reduce watering frequency. Cut back or prune hard in late winter to rejuvenate. Move indoors or reduce outdoor exposure in cold climates
Common Pests

Harvest Tips
Harvest leaves and stem tips regularly once plant is established (4-6 weeks after planting). Pinch 0.5-1 inch from stem tips to encourage bushiness. Morning harvest after dew dries yields best flavor and aroma. Remove no more than one-third of plant at a time. Can be harvested continuously throughout growing season
