pH: 6.0–7.5  ·  Well-drained; tolerates poor soil

Low nitrogen; too much N reduces seed production

Amaranth is a heat-loving annual grown for both its nutritious grain-like seeds and colorful edible leaves. The plant produces dramatic flower spikes in red, gold, or burgundy and is valued by gardeners for its drought tolerance, prolific yields, and dual-purpose harvesting. It's a staple in traditional cuisines and increasingly popular with home growers seeking grain crops and nutrient-dense greens.

Amaranth germinates in 7 to 10 days at soil temperatures between 70 and 85°F, with 75°F optimal. Seeds are tiny and prefer light to germinate, so sow them on the soil surface or press them in lightly without covering. No pre-treatment is needed. Start seeds indoors 4 to 6 weeks before the last frost, or direct sow after frost danger has passed and soil has warmed.

Cover the seeds lightly with a thin layer of seed-starting mix, as amaranth seeds require light to germinate.

Plant amaranth in full sun and well-draining soil enriched with compost; it tolerates poor soil but produces better in fertile conditions. Water regularly during establishment and dry spells, though established plants are quite drought-tolerant. Thin seedlings to 6 to 18 inches apart depending on variety; leaf varieties can be closer. Fertilize lightly every 3 to 4 weeks with a balanced fertilizer or side-dress with compost. Amaranth rarely needs staking and has few serious pests, though leaf beetles and spider mites may appear in hot, dry weather—spray with neem oil if needed.

Harvest leaves continuously once plants are 6 inches tall by pinching off the top 2 to 3 inches, which encourages bushier growth and extends productivity. For grain, wait until flower spikes turn brown and dry (usually 90 to 110 days), then cut entire heads and hang in l a dry place to cure for 2 to 3 weeks before threshing. Strip seeds from dried heads by rubbing gently, then winnow away chaff. Store dried seeds in airtight containers in a cool, dry place for up to a year.
