We have this section of trees we didn't clear when we built our house. We love them for a bit of privacy/noise/light filter but every year the weeds grow up so tall and dense I feel like its a bit of an eye sore. I was wondering if I sprayed it now with a weed killer before they start growing (in Wisconsin so snow just left) and then put a couple inches of mulch down, would it keep most of the weeds away? And I guess more importantly, would it look good/is that a normal thing to do or do people just leave clusters of trees like this on their property alone?
