Brown curling leaves on Oak Leaf
My oak leaf hydrangea has leaves turning brown with curling edges. A few weeks ago there were signs of insect infestation, so at the recommendation of my local coop, I sprayed with a product called Eight. Since then the brown areas are getting worse. Many leaves are dying. I'm thinking maybe a fungus that was untouched by the insecticide? Too much sun? It gets morning sun, but around here, that can be pretty darned hot. I'm tempted to cut it way back, but should I move it to a shadier location too? Spray for fungus? Thanks.
