Germination & Seedling
2-3 weeksTiny cotyledons emerge within 5-10 days. First true leaves develop, showing initial purple coloring.
Keep soil warm (70-75°F) and consistently moist. Provide bright light immediately after sprouting. Thin seedlings to prevent damping off.
Vegetative Growth
3-4 weeksPlant develops multiple sets of true leaves with characteristic ruffled edges and deepening purple color. Bushy growth begins.
Pinch off top growth when plant reaches 6 inches to encourage branching. Feed with balanced liquid fertilizer every 2 weeks. Maintain consistent moisture.
Flowering
Ongoing from week 8+Purple-pink flower spikes emerge at branch tips. Flowers are attractive but drain plant energy if not harvested.
Pinch off flower buds promptly to extend leaf production and flavor. If allowing flowers for ornament or pollinators, reduce watering slightly.
Mature Harvest
4-8 weeks or until frostPlant is full, bushy, and at peak leaf production. Purple foliage is vibrant and ruffles are most pronounced.
Begin regular harvesting from top to maintain shape. Remove leaves from top down, leaving lower stems intact for regrowth.
Senescence
Until first frost or end of seasonPlant slows growth as temperatures cool or in response to stress. Leaves may become less tender.
