I'm trying to control Bitter Pit in my Jonagold apples. Do you have any suggestions on what to use and when to use it?

Hello, my question is how detrimental would it be to trim a large limb on a sugar maple at a fence line right now in the winter or really anytime given the size of the limb? A small ADU house was built right at the lot line under our maple tree about two years ago this kind was already grown over the lot line. Now the owner of this house wants to cut a major limb (that was there when she bought the house) because she is afraid it will damage her house. What will this do to our tree? Especially cutting it now in the winter? I have attached a photos of where the neighbor wants to cut the tree.

Hello, I live in Mt, Airy, MD. I have a variety of trees including apple, peach, pear, plum, and cherry. They are 2 years old now give or take. I have noticed that there is some scabbing and curling on a lot of the leaves during the season, especially with the peach trees. I don't use any chemical fertilizers, herbicides, or pesticides. I am curious what this is and what I can do about it? I wrote a question before, but not sure if a reply came back through or not. Thank you for your help.
