I planted a A. palmatum "Tamukeyama" about 2 months ago and now over a 3-4 day period some of the leaves are turning brown. I don't see any signs of pests. Is there any kind of disease that this tree is susceptible to? Could I have watered the tree too much? What can be done to save it? Thanks!
If you think you have been watering the tree too much you probably have These trees like good drainage and if the roots are too wet they suffer Give it a rest and keep a close eye on progress If in real doubt you could dig it up and examine the rootball to see if it is sodden. As it is only planted about two months this should not be too much of a shock to the tree See other threads on how best to plant a Japanese maple
Japanese maple cultivars are disease-susceptible. Questions about problems with them are frequent. Partial dieback involving whole branches is likely to be a pathogenic infestation. It has been claimed some stock is being sold already infected as the result of careless or uniformed production practices. For diagnosis of specific agent at work try Arkansas Cooperative Extension.
yes, take them fresh samples. it is free of charge. not only take them leaf samples, but also submit a cutting of a branch in an inconspicuous place. they will send if off to the plant disease clinic in Lonoke.
