Trim up around it and put a heavy layer of mulch down. Be careful when blanket spraying the area to not use something that the tree will be sensitive to. I would just put down the mulch and spot treat anything that pops up. Some cardboard under the mulch would help, but don't use landscaping fabric or you will be kicking yourself in the future. Been there, done that.
Mulch for weed control around existing trees
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?
