The seeds are edible and have been used as a grain in Germany and especially Poland, where it is sometimes cultivated.   This has earned it the name Polish Millet, and it was brought to the United States by some emigrants to serve as hand-foraged grain. The grass is also highly nutritious, especially before the plant exhausts itself producing seed. It is frequently sown in fields to provide graze for animals, or clipped and bundled as hay. Compared to other grasses, it has a relatively high protein percentage. Farmers will sometimes till patches in their pastures in the late spring, with the intent of encouraging crabgrass seed.

For human consumption, crabgrass necessarily must be harvested by hand, because it produces grain throughout summer, rather than simultaneously. Machine harvesting would require monthly passes, and even then much of the seed would go to waste. This said, crabgrass produces an exceptionally high amount of grain, it smothers other weeds, it acts as its own mulch, and it can survive both heat and drought. Its adaptability makes it a candidate for environmental small-farming.

Its usefulness to nineteenth-century homesteaders, however, has made its seed widespread, and today is considered an unattractive nuisance. Crabgrass takes advantage of low fertility and drought, since this tends to weaken other grasses. It is difficult to kill, as it will regenerate, and chemicals will likely harm surrounding grasses. The most efficient means of control is to pull patches, and keep the rest of the lawn watered and mowed at a height of two-three inches.

Prefers a sandy soil. Requires a warm sheltered position. This species is occasionally cultivated, especially in Poland, for its edible seed. Special Features: Invasive.

Propagation :
Seed – best sown in situ in the spring. Only just cover the seed.

Medicinal Uses:
A decoction of the plant is used in the treatment of gonorrhea. A folk remedy for cataracts and debility, it is also said to be emetic.

Other Uses: A fibre obtained from the plant is used in making paper.

Known Hazards : There is a report that the leaves might be cyanogenic.
