Hi there, I live in scotland and i recently bought a apple and pear trees, about 12 inches in height, but lately they both have had problems. The apple tree leaves seem to have a white powder on it and the leafs are curling up and falling off, the pear tree leaves have started going brown around the side till they are totally brown and just fall off, and the branch at the top where the bud is seems to be going black!! I need help urgently please!
