I hate a tree.

If any branches come into your backyard, I believe you are allowed to cut them. My neighbor’s branches
used to come into my backyard and they were blocking the Succah, so after asking permission of the neighbor I had them trimmed,. You would have to call a tree guy and pay over $100 but it might be worth it for you, for menuchas hanefesh. We Yiden are not supposed to harbor enmity. When we have a problem with someone, we need to try to work it out, especially now in Elul.

Didn’t Yoshko (I think) curse a tree?!?

Our building has one tree growing on the shared building property, next to the parking lot. It gives a bit of green amidst all the grey concrete. It shades the parking spots, shades our windows and gives us a bit of privacy so the neighbors in the next building do not have a clear view of our windows.
Until… one neighbor decided to build his sukka last year in a public area next to the parking lot (right under our bedroom windows). And under the tree. So he cut down all the branches on 1 side. There were 3 limbs left. This year, he decided the largest limb was covering a corner of his very large sukka. He asked one neighbor if they minded if he cut down the tree. They said they did mind, but he can trim a bit if it blocks his sukka. He went and cut down the largest limb. Never asked us, even though that limb was closest to our apartment. Now we have no shade and no privacy, and while he may enjoy his super large sukka for 1 week of the year, we are left to suffer for all 52 weeks. I miss that branch. Now every time we hear the neighbor drilling on his sukka (last year it took him about a month to build it, usually around my kids’ bedtime) I will miss that tree even more.
