Seedling
3-4 weeksSmall plants with 2-4 leaves, tender and delicate appearance
Keep soil consistently moist; provide bright indirect light; protect from strong winds; maintain temperatures above 70°F
Vegetative Growth
4-6 weeksRapid shoot and leaf development with increasingly bushy appearance; plant reaches 12-18 inches
Begin light harvesting of outer leaves once plant has 6-8 leaves; provide regular watering and humidity; apply balanced fertilizer every 2 weeks
Established Bush
Ongoing for months to yearsFull, bushy plant 2-3 feet tall with abundant tender leaf shoots ready for regular harvesting
Harvest outer leaves regularly to promote bushiness; pinch growing tips to encourage branching; maintain consistent moisture and humidity; fertilize monthly
Flowering
Variable, flowering occurs periodicallySmall greenish flowers appear in leaf axils; tiny round fruits may develop but are not primary focus
Continue regular leaf harvesting; fruits are rarely eaten; maintain consistent care routine
Mature Production
6+ months to several yearsLarge established shrub producing abundant harvestable leaves continuously; may reach 4-6 feet if unpruned
Continue regular harvesting and pruning to maintain shape and encourage tender new growth; provide consistent nutrients and water; can be grown as long-term perennial

Harvest Tips
Begin harvesting leaves when plant is 8-10 weeks old and has established 6-8 leaves. Pinch off tender outer leaves and growing tips regularly (every 5-7 days) to encourage bushiness and continuous production. Harvest in early morning for best flavor and nutrient content. Remove yellowing or damaged leaves. Can be harvested continuously for months to years; the more you harvest, the bushier the plant becomes. Leaves are best eaten fresh or lightly cooked within a few days of harvest.
Fun Facts
