Seedling
10-14 daysTiny seedlings emerge with cotyledons; plants are fragile and susceptible to damping off.
Maintain consistent moisture without waterlogging. Provide bottom heat (70-75°F) to improve germination. Thin seedlings to proper spacing once they have true leaves.
Vegetative Growth
25-35 daysPlant rapidly develops true leaves and stem; foliage begins showing pink and green coloration. Height increases significantly.
Maintain even soil moisture and provide consistent full sun. Apply balanced fertilizer every 3-4 weeks. Monitor for pests. Thin to final spacing of 12 inches.
Flowering & Head Development
15-20 daysDistinctive fluorescent pink flower heads emerge at the top and in leaf axils. Foliage becomes increasingly vibrant in color.
Reduce nitrogen to encourage flowering; apply phosphorus-rich fertilizer. Ensure adequate water during this critical stage. Stake taller plants if needed in windy locations.
Grain Maturation
20-30 daysFlower heads mature fully, developing the characteristic bright pink coloration. Seeds inside the flowers begin to harden and dry.
Continue regular watering but allow soil to dry between waterings. Reduce fertilization. Heads may be harvested for ornamental use at peak color.
Harvest Ready
OngoingFlower heads are fully mature with deep pink coloration. Seeds are dry and hard, and foliage begins to senesce.
Harvest grain by cutting flower heads and allowing them to dry completely in a warm, airy location. For fresh greens, can be harvested anytime from young plant stage.

Harvest Tips
For leafy greens: Harvest outer leaves once plant is 6-8 inches tall, pinching from the top to encourage branching. Continue harvesting until plant flowers. For grain: Cut entire flower heads once they are fully mature and bright pink (usually 90-100 days). Hang heads upside down in a warm, dry location for 2-3 weeks. Rub dried heads between your hands to release seeds. Winnow to remove chaff. Seeds store well for several years in cool, dry conditions.
