Sorry you had to try again to get a reply to your query
Many acers have suffered over the past winter because of the constant rain. I myself have lost an acer this year because of being saturated.
Your acer with its fine leaves is a particularly vulnerable plant ....it doesn't like direct hot sun or cold winds. Is yours in a windy position? Can you move it to a more protected spot?
Every spring I would cut out any dead wood and trim back to healthy shoots.
I would not feed too much either as I sense ??ou may have overdone this. Feeding isnt a solution to damage caused by growing conditions. Do you tend to water it a lot?
So. I would cut out dead wood, make sure it's in a sheltered spot and resist watering too much. Also check for vine weevils...acers in pots are susceptible to these pests. You can buy vine weevil killer to apply to your tree
Good luck Sue
