My Japanese Maple leaves seemed to shrivel up last year. The tree has buds this year. It is planted near to a Black Walnut. Could that be the problem?
Japanese Maples can tolerate the Juglans secreted by Black Walnuts but these trees take a lot of moisture out of the soil. I wonder if your Japanese Maple is suffering from lack of moisture. Can you move it farther away from the Black Walnut?
Provide dappled shade, soil replenished with organic matter, protection from severe winds and cold, and make sure the soil does not dry out completely during hot dry spells. Young foliage can be affected by late spring frosts.
