Hi. This apple tree was new when I moved here 9yrs ago. But I had no idea I had to prune it๐. I read through other questions and it seems I need to first move the tree obviously. Then find a central leader branch, and remove any water sprouts etc. I have already cut crossing branches also . The pic shows that there are 3 main branches! How much more can be trimmed without killing it? So Im stumped. Hahaha. Thank you.
