Planting Amaranth (Grain)

Amaranth (Grain) is a warm season vegetable in the Amaranthaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.

Amaranth (Grain) is started indoors 3–4 weeks before your last spring frost date, giving seedlings a head start before they move outside.

Sow Amaranth (Grain) directly into the garden 1–2 weeks after your last frost, once the soil has warmed.

Amaranth (Grain) can be grown by direct sowing and starting indoors. Starting indoors gives the longest, most controlled season, while direct sowing is simplest where the season is long enough.

Conditions and Care

As a warm-season vegetable, Amaranth (Grain) needs warm soil and settled weather to thrive, and is set back or killed by frost. It is frost tender, so wait until all danger of frost has passed before planting out and harvest before the first fall frost.

Amaranth (Grain) needs full sun — give it at least six hours of direct light a day for the best growth and flavor. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.

Amaranth (Grain) belongs to the Amaranthaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Amaranth (Grain) is generally grown as a single planting each season rather than succession sown.
