How to Grow Amaranth from Seed

Bed Preparation

Amaranth is a frost sensitive annual that prefers full sun and tolerates a wide variety of soils. Drought tolerant once established, but most productive in moist rich soil.

Planting

Amaranth can be direct seeded outdoors once the danger of frost has passed. Seeds can also be started indoors 4-6 weeks before the last frost. Sow seeds 1/8” deep and 1-2” apart. Seeds will sprout in 8-12 days. Thin seedlings so that mature plants are 6" apart.

Harvest

Harvest amaranth greens in 30-40 days after planting. Flowers can be harvested in 45-70 days and grains in 75-110 days.

How to Save Amaranth Seeds

Amaranth is self-pollinating, but will also readily cross with other varieties and the wild-type amaranth, which is quite common. Flowers should be bagged to prevent cross-pollination and maintain seed purity. Collect the seed heads as they begin to dry on the plants and store in closed paper bags to finish drying. Most of the seeds will shed on their own into the bags. Don’t let heads get wet after they dry. Chaff easily blows away after seed heads are crumbled. Watch for thorns and prickles in some plants!
