📏
Spacing: 12-18 inches apart depending on variety; thin seedlings to prevent crowding inches
📅
Days to maturity: 50-80 days for leaf harvest; 120-150 days for seed production
🌱
Planting depth: 1/4 inch; seeds are tiny and prefer light coverage

Soil

Type: Well-draining loamy soil with moderate fertility
pH: 6.0-7.5
Amendments:
Compost Aged manure Perlite for drainage Avoid excessive nitrogen which promotes foliage over seeds

Growth Stages

1

Germination & Seedling

2-3 weeks

Tiny leaves emerge within 7-10 days; seedlings are delicate with 2-4 true leaves visible

Keep soil warm (70-85°F optimal) and consistently moist. Provide bright light to prevent leggy seedlings. Thin overcrowded seedlings early; thinned greens are edible.

2

Vegetative Growth

3-4 weeks

Rapid leaf expansion with characteristic colors deepening; plant develops 6-12 inches in height with visible leaf variegation becoming pronounced

Begin harvesting outer leaves when plant is 8-10 inches tall. Water consistently and fertilize every 2-3 weeks with balanced fertilizer or compost tea. Remove competing weeds.

3

Flowering & Seed Production

4-6 weeks

Dense flower spikes (inflorescences) emerge from stem terminals; grain varieties produce dramatic upright or drooping seed heads; ornamental value peaks

For seed harvest, allow flowers to mature fully and dry on plant. Stop harvesting leaves to redirect energy to seed production. Protect from birds with netting if desired.

4

Seed Maturation & Harvest-Ready

2-3 weeks

Seed heads darken and dry; seeds become hard and fall readily when rubbed; foliage may begin to senesce

Cut seed heads when fully dry and brown; thresh and winnow to separate seeds. Store dried seeds in cool, dry conditions. Entire plant can be dried for seed harvest.

Harvest Tips

For leaf harvest: Pick outer leaves when plant is 8-10 inches tall, allowing inner leaves to continue growing; harvest regularly (every 2-3 weeks) to encourage bushiness and prevent bolting. Leaves are tender and best when young. For seed harvest: Allow entire plant to dry on plant or cut seed heads when brown and dry; thresh and winnow to separate seeds; seeds store 3-4 years in cool, dry conditions. Best flavor and nutrition in young leaves; older leaves become slightly bitter.

Fun Facts

  • 🌱 Amaranth was a sacred crop of the Aztecs and has been cultivated for over 8,000 years; it was banned by Spanish conquistadors but has experienced a modern revival as a superfood.
  • 🌱 Despite being called a grain and cooked like one, amaranth is botanically a seed and is technically gluten-free, making it valuable for those with celiac disease.
  • 🌱 A single amaranth plant can produce 60,000+ seeds, making it extremely efficient for seed-saving and explaining its historical importance as a survival crop in harsh climates.
