I need help with my pear tree. We moved into our house and it has a pear tree. First August the pears were plentiful, huge, and juicy. Last year the pears barely grew then shriveled and turned black on the tree. This year the pears are growing so far but the pears have spots on them and some of the leaves have spots too. Any idea what could be wrong with the tree? I have no idea how to take care of a pear tree. I just want the tree to be healthy and have amazing pears again!!
