Hello all, I am a first time poster to this board! I was hoping to find some good advice and discussion. Last year, I purchased a house that came with some great landscaping (which I know absolutely nothing about). To my surprise, one of the trees has given me some delicious citrus fruit! It looks like lime, but tastes like lemon.

Several of the branches on this tree have wilty leaves. I tried applying neem oil but didn’t notice much difference. Could anyone help me identify this tree, and if so does anyone have any idea what might be causing the leaves to wilt?
