Germination & Seedling
10-14 daysSeeds sprout within 7-10 days in warm soil (70-80°F). Tiny seedlings emerge with cotyledons and first true leaves appearing within 2 weeks.
Maintain warm, moist soil; thin seedlings to proper spacing when 2-3 inches tall. Remove weaker seedlings to reduce competition. Keep soil consistently moist but not waterlogged.
Vegetative Growth
20-30 daysPlant develops multiple stems and abundant foliage; characteristic red coloration intensifies in leaves and stems. Bushy growth habit with 6-12 inch plant height.
Water regularly; fertilize every 2-3 weeks with balanced fertilizer or compost tea. Pinch off flower buds if growing solely for leaves to extend leaf production. Thin crowded plants to improve air circulation.
Leaf Development & Continuous Harvest
30-60 daysPlant reaches harvestable size; outer leaves mature while center continues producing new growth. Red coloration deepens; plant may be 12-18 inches tall.
Begin harvesting outer leaves when 4-6 inches long. Regular harvesting stimulates more leaf production. Continue moderate watering and fertilizing. Monitor for pest pressure.
Flowering & Seed Production
20-30 daysIf allowed to mature, plant produces tall flower spikes with small red or crimson flowers. Grain-like seeds develop in dense panicles.
For seed saving, allow select plants to flower and mature completely. Leave one or two plants unharvested to produce seeds. Harvest seed heads when they turn brown and begin to dry.
Harvest & Season End
Varies by climatePlant becomes woody and flavor deteriorates in extreme heat; new growth slows significantly. Plants may decline in late season.
Increase watering frequency during peak heat; provide afternoon shade in very hot climates. Replant in succession for continuous supply. In cool climates, plants may produce into fall.
