An easy plant to grow, but it requires a long growing season if you want seed and will only germinate above 10C, preferably above 20C, so you will need to start them off indoors early in the season. Hardy to zone 5. Amaranth accumulates nitrates in its cells when grown non-organically, so it is advisable to grow your own without chemical fertilisers. Prefers a light well-drained fertile soil in a sunny position, though it does succeed in heavier soils. Tolerates fairly acid soils. Tolerates a pH in the range 4.3 to 7.8. This is basically a tropical plant and so requires a hot sheltered position in temperate climates if it is to do well.
