Amaranth

Amaranth plants should be watered regularly throughout their growing season with about 1 to 2 inches of water per week. Water deeply once a week to ensure that the soil in your garden is completely saturated. Water your amaranth plants in the morning, and avoid wetting the foliage directly as this can lead to disease. During periods of intense heat and drought, increase the amount of water you give your plants to 1 to 2 inches per day. If you live in an area with high humidity, you may need to decrease the amount of water you give your plants.

Amaranth (Amaranthus hybridus x var. tuberculatus) grows best in full sun, which would be at least 6 to 8 hours of direct sunlight per day. Optimal growth for Amaranth takes place in warm climates with sunny days and cool nights. Exposure to morning sunlight and afternoon shade is ideal, as the cooler temperatures of evenings and mornings are beneficial for many varieties of Amaranth. Too much direct sun or heat can cause foliage to become scorched, so afternoon shade can help protect against such damage.

Amaranth (Amaranthus hybridus x var. tuberculatus) should be pruned in the late spring or early summer after the plant has flowered. The aim of pruning is to help remove damaged or diseased stems and leaves, and to control the shape and size of the plant. Prune only 8-12 inches of the plant at 1 time, as this should be enough to keep the plant healthy without significantly reducing its size. Pruning should be done with a pair of sharp scissors, and any dead or damaged stems should be removed. If the plant is too large, or if intensive pruning is required, it is best to prune it in stages over the course of several weeks.
