seiryu japanese maple
I have a seiryu japanese maple that has been in the ground for 3 years. It's always been really beautiful, healthy tree but this year in early April it started to get leaves and then just stopped. These new leaves were about half the size of what they should be and have now all completely died, turning reddish brown.
The tree hasn't done anything at all in over a month but the branches are still very flexible and green on the inside.
Anything else I can do to see if it's alive?
Thanks, don't know what I'd do without all your help.
