Hello, We have a young maple tree in our backyard which has been growing taller for the last 2 years since first discovered as a sapling. My concerns are that there are multiple trunks and it's not shaped properly. Not knowing much about this, it seems it is in dire need of some pruning. I'm not certain on approach, even after spending some time on various sites and reading other threads on this forum. I'm trying to understand is now a good time to prune? I'm in the suburbs of Chicago. What and how much should I prune? What areas would make the most sense to do first? Thanks.
