Pear tree had black leaves
I have inherited 2 pear trees with my new house. The leaves are going black and I don’t know what to do. I think they appear to be 3-4 years old about 6’ tall. Lots of flower and now fruit beginning and I’ve kept it watered it’s in a raised bed against the house. Could someone give me advice and hopefully I can save them. One is much worse. I don’t know how I didn’t notice this sooner. See the pictures I’ve added. Branches seem ok just leaves.
