Nut grass is called 'the world's worst weed'. It is a tough competitor for nutrients and it's roots release a substance called allelopathic which is harmful to other plants. Weed pulling is not effective for nut grass as the breakage of roots resulted in leaving it's tuber underground. New plant will then emerge quickly. Most of the herbicide have no effect against nut grass tuber and roots but only kill the leaves.
