We have a japenese maple that is about 5 years old and it did not make it thru the winter. Also a Plum ? (purple leaves) that did not make it either. One is in the front and the other in the back but in a straight line from each. A nursery suggested we get in touch with you . Also had to cut back our fig tree. All the branches were dead but something seems to be coming out of the ground. Thanks, Eleanor DePhillips
I would recommend that you contact your local Extension office in Lehigh County. Their telephone number is 610-391-9840. They will likely ask you to submit a sample of the trees to them for diagnosis of the problem.
Have a great day!
