Q.Red Maple tree brown edge leaves
Planted a 5‘ Red Maple a few months ago. When I water it (2x per week depending on weather), it seems that the leaves curl up and turn brown on the edges. ALL of the leaves on the tree have brown edges. OR is it because I don’t water it enough? The tree gets nothing but water. I live in southeast Wisconsin. All help appreciated.

It is because the tree is not getting enough water. The first year, trees need an enormous amount of water to establish well. Unless they are in standing water, you can't over water them. I would recommend increasing water to the tree for the remainder of the growing season.
