Planting Amaranth

Prefer a well drained rich loam soil or compost. Amaranth plants are susceptible to frost; if sow seeds outdoors, wait until soil has warmed and any chance of frost passed. It is safer to start indoors about 6 to 8 weeks before the last frost. Space seeds or seedlings 10 to 12 inches apart; cover seeds lightly with soil.

Growing Amaranth

Water them during dry periods, once or twice per week. Add a general purpose fertilizer once or twice a season. Mulch plants to minimize weeds.

Harvesting and Storing Amaranth

Seed will be ripe in about 3 months.To check if seed is ready to harvest, gently but briskly shake or rub the flower heads between your hands; ripe seeds easily fall off the plant. You can gather ripe grain by using the same technique over a container as you rub with your hands.
