Seedling
1-2 weeksTiny cotyledons emerge with first true leaves appearing within 7-10 days. Seedlings are delicate and light green.
Keep soil consistently moist but not soggy. Provide bright light and warm temperatures (70-80°F). Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
2-3 weeksRapid leaf development with multiple branches forming. Plants become bushy and vigorous with increasingly larger leaves.
Maintain consistent moisture and warmth. Apply balanced fertilizer or compost tea every 2-3 weeks. Begin harvesting outer leaves once plant reaches 6-8 inches tall.
Leaf Production
3-4 weeks and ongoingPlant reaches mature height (1.5-3 feet) with dense foliage. Continuous leaf production throughout the season.
Regular harvesting promotes bushier growth and extends productivity. Water deeply and maintain consistent fertilization. Mulch around base to retain moisture and regulate soil temperature.
Flowering
Variable; delay with proper careSmall, inconspicuous greenish flowers appear at stem tips as plant matures or if stressed by temperature/drought.
Pinch off flower buds to encourage continued leaf production and delay maturity. If flowering occurs, plant quality declines for harvesting.
Seed Production
2-3 weeks after floweringIf allowed to flower, tiny brown or black seeds develop in clusters. Plant becomes less palatable.
Allow to fully mature only if collecting seeds. Otherwise, continue harvesting or remove plant to prevent self-seeding.

Harvest Tips
Begin harvesting when plants are 6-8 inches tall by pinching off outer leaves and stem tips, leaving the central growing point intact. Harvest regularly (2-3 times per week) to encourage bushier growth and prolong production. In warm climates, plants can produce for 2-3 months or longer. Pick young, tender leaves for best flavor. Early morning harvesting yields the crispest leaves.
