Spring Planting:

 

Amaranthus can be started either indoors or outdoors. Some experts recommend starting it indoors 6-8 weeks before your last frost date and transplanting it after the danger of frost has passed. You can direct sow, but wait until soil temps are warm and all danger of frost has passed.

 

How to Grow:

 

Direct sow or transplant in moist, well-draining soil in full sun to a depth of 1/8 inch. Thin or plant 18-24’’ apart. It is somewhat drought-tolerant. However, amaranthus likes moist but not soggy soil. It blooms in summer and continues to bloom until the first frost. Keep the beds weed-free while the amaranth are young. Once they are established, they will be able to outcompete any competitors.

Harvest:

 

Young greens are perfect for salads, while older greens are better when cooked like spinach. The seeds either raw or cooked “can be used as a cereal substitute. They can also be popped in much the same way as popcorn. The seed can be soaked for 12 hours in warm water and then allowed to sprout for about 11 days. [Then] they can then be added to salads. [The seeds are] very small but the seed is easy to harvest and very nutritious. The seed can be cooked whole and becomes very gelatinous like this. But it is rather difficult to crush all of the small seeds in the mouth and thus some of the seed will pass right through the digestive system without being assimilated.”¹

Seeds ripen about three months after planting. They are ready to harvest when they begin to fall from the flower head (tassel). Give the tassel a gentle shake. If you see seeds falling from the tassel, it’s Amaranthus seed harvest time.

Seed Saving

Isolation Distance

Insect and wind dependent for pollination. Isolate 1/4 mile to prevent cross-pollination.

 

Instructions

Select healthy, robust plants free of any signs of disease or insect infestation for seeds. Seeds carry the traits of the parent plant. Choose plants that exhibit the traits you wish to preserve. Consider bloom size, color and shape, as well as blooming time.

 

Allow the biggest and healthiest blooms to mature on the plant. Cover the seed head with a fine-mesh bag as soon as the flower petals shrivel and die. Use an elastic band to hold the bag in place. This prevents seeds from spilling onto the soil before harvest.

 

Clip the flower head from the main stem once the seeds are dry and dark. Separate plant debris from the seeds by removing the mesh bag and placing the flower head in a paper bag and shaking to loosen the seeds. Seeds settle to the bottom of the bag. Remove plant debris by hand.
