Growth Stages

Seedling

2-3 weeks

Tiny plants with first true leaves appearing; foliage begins showing purple-red tint

Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing once 2-3 inches tall. Protect from slugs.

Vegetative Growth

4-6 weeks

Rapid height gain with deep red foliage becoming more prominent; leaves elongate and darken

Water regularly during dry spells. No fertilizer needed in fertile soil; avoid nitrogen excess which reduces color intensity. Support tall varieties if needed.

Flowering

3-4 weeks

Dense, plume-like flower heads develop at the top and sides; flowers are deep crimson to burgundy

This is peak dye harvest time. Reduce watering slightly. Monitor for pests. Flowers attract pollinators and beneficial insects.

Seed Development

2-3 weeks

Flower plumes transition to seed heads; color may fade to russet-brown as seeds mature and harden

Minimize watering. Allow plants to dry naturally. Seed heads become heavier; ensure staking if needed.

Harvest Ready

Varies; typically by September-October

Seed heads are completely dry and brittle; foliage may yellow. Seeds fall easily from plumes when rubbed.

Cut entire plant or remove seed heads. Dry completely before threshing. Store seeds in cool, dry location.

Uses

🍳

Nutritious Whole Grain

Culinary

Amaranth seeds are complete proteins containing all essential amino acids, along with high levels of magnesium, iron, and fiber. Cook like quinoa (1 part seeds to 3 parts water) or pop like popcorn for a nutritious snack. [source]

🍳

Leaf Vegetable

Culinary

Young amaranth leaves are edible and highly nutritious, with a mild spinach-like flavor. Harvest tender tops and use fresh in salads or cooked as greens. [source]

Harvest Tips

For dye: Harvest flower heads at peak color (mid-flowering stage), tie in bundles, and hang-dry in shade for 2-4 weeks. For grain: Allow seed heads to fully dry on plant until brittle, then cut and thresh by rubbing heads together over a cloth. Winnow to remove chaff. Wear gloves when handling fresh flowers as dye can stain hands.
