What do you do when you have patches in your lawn of a thick-bladed grass? There are various types of grasses that can spoil the appearance of your lawn. With the touch of snow this clump of grass seems to stand out more than it might if the snow wasn’t there. Some people say, “at least it’s green and doesn’t have yellow flowers.” Some, however, are adamant that the grass has to go.
By the way, if this unwanted grass is visible at this time of year (April, May or early June), it is NOT crabgrass, and putting on a crabgrass treatment will not do anything to help.
There are a number of thick-bladed grasses that can grow in lawns around here. Quack grass or twitch grass, brome grass, orchard grass, timothy , and others as well. The names are less important than what one does to tackle the issue.
Since these are perennial grasses, there isn’t a selective treatment that you can apply to the whole lawn and make only the grasses we don’t like disappear. A herbicide containing glyphosate was the best in the past, but can no longer be used in Ontario.( Roundup is the most common brand name for such a product.)
By the way, (again), I don’t recommend trying to dig up the thick-bladed grasses. Several years ago, I went to give a lawn quote. The homeowner met me and showed me his lawn. He had at least fifty nice round spots of fresh soil on his lawn. “What happened here?” I asked. He told me he had dug up all the areas of the thick-bladed grasses on his lawn. “Did you spray the grasses first?” When he said that he had not, I told him that unfortunately the roots on these grasses can be deep and if a small piece of root was left it could grow back again. Sure enough, a few months later, around the edges of the spots he had dug out, there were little sprigs of the thick-bladed grasses starting to grow back.
Without herbicides, there is no easy way to get rid of Quack Grass.
