Germination & Seedling
7-14 days to germination; 2-3 weeks to thinning stageTiny seedlings emerge with oval cotyledons and initial true leaves. Red coloring begins to appear on stems early.
Keep soil warm (70-80°F) and evenly moist. Thin seedlings to proper spacing when 2-3 inches tall. Provide bright light to prevent leggy growth.
Vegetative Growth
2-4 weeksPlant develops multiple stems with increasingly vibrant red coloring and lush green foliage. Stems thicken and elongate.
Maintain consistent moisture and warmth (65-85°F). Apply compost mulch to retain moisture and suppress weeds. Begin light harvesting of outer leaves once plant is 6-8 inches tall.
Leaf Development & Maturity
2-4 weeksPlant reaches productive size (12-24 inches tall) with abundant tender leaves and prominent red stems. Foliage darkens and develops rich red veining.
Continue regular watering and begin harvest cycle. Pinch out flower buds if growing for foliage only. Side-dress with compost or balanced fertilizer if needed.
Peak Harvest
4-8 weeksPlant is in full production, offering abundant harvestable leaves and tender stem segments. Red coloring is most intense.
Harvest outer leaves and stem tips regularly to promote bushier growth and extended production. Maintain moisture during hot weather.
Flowering & Decline
2-4 weeks until end of seasonIf not harvested heavily, plant produces small inconspicuous flowers and seeds. Foliage may become tougher and less palatable.
Pinch back flowering stems to extend leaf harvest. Plan succession plantings in long-season areas. Plant naturally declines as temperatures cool.
