About An Acer Tree

Question

I have a 12yr old acer tree. It was repotted about 18 months ago. It gets aphids every spring. At the moment big chunks of the tree are dying and the leaves are dropping. I’ve tried cut off the dead areas and sealed the cuts with an anti fungal powder but I don’t think I can’t keep doing that there will be nothing left. I’ve now bought a product to kill weevils (nemasys). Can I save my acer?

Your tree could have borers. They eat inside the tree so are hard to control. Here are other possibilities you can check for:
