What's killing my trees and shrubs?
I lost a mature flowering cherry last year - it was riddled with what looked like woodworm and was crumbly and desccicated. Once I removed it, I burned the wood, dug over the soil, put ericacious soil in the hole where I placed a Rhododendron, covered with weed suppresent mat and bark chippings. The Rhododendrom flowered beautifully earlier but now it looks exactly like the cherry, leaves are curled, dry and it looks dead. I don't know what to look for. Help greatfully appreciated.
