I have an invasive, fast growing, very coarse grass (?) appearing in spots throughout my lawn. It has a very shallow root system. I’m not sure what I’m dealing with and how I should be handling this. Would appreciate any thoughts you might have. Susan Gladstone
It sounds like crabgrass. It is an annual so it will die with frost after leaving behind a crop of seeds that will sprout next spring for the next cycle. The best control is crabgrass preventer applied at the right time in spring. HERE’S a link to explain the timing of crabgrass preventer in spring.
