help to identify the problems with a 2 year old apple tree
Please help me to identify the problem with my 2 year old apple tree. I am very inexperienced gardener, so any help will be much appreciated.
It looks like some insect colony.I have attached the three photos which I hope will help you to identify the problem. I would be extremely grateful if any of the more experienced gardeners would advice me on the best way to solve this.
