Hello, I am Nutgrass
I am called Nutgrass as I am tall grass-like plant with a deep-rooted nut. However I am not actually a grass but a sedge. I have triangular leaves instead of flat blades like grasses do. As a weed, I spread mainly through underground runners, which connect a network of nuts. However I will also flower and disperse seeds through wind dispersion and by sticking to clothes or animal fur. I can be very difficult to eradicate. If you just pull me up by my leaves, I release the leaves but leave the underground nut. Unless you also dig out this nut, I will replace those leaves and grow stronger in the process.
WHAT I’M TELLING YOU
I grow best in acidic, compacted.soils that are deficient in clacium. Correct your soils and I will no longer be a problem.
I am best controlled by hand weeding. Just make sure you dig deep enough to remove all my underground nuts, as I will reproduce from any corm left behind. This can be a difficult job as the nuts need to be dug up and can be 20cm or more below the surface. I am very good at releasing my leaves to trick you into believing you have killed me, but return even stronger. I do not respond to being sprayed with any weed killers. However, I can be controlled using biodynamic peppers. See Magical Biodynamics
