Hi I hope someone can give some advice. My Mum's neighbour has always been really helpful in looking after her garden and about 2 years ago he decided to pollard her Oak tree. He also treated with "tar oil" as there was apparently an insect infestation on the tree. Since this was done the tree hasn't really recovered, has been some green growth on the tree, but this appeared to die off in August.
The oak is nearly 50 years old so I’d like to try and do my best to try and save this if I can. Any suggestions on how to remove the oil off the tree?
I'm not sure if it makes any difference but the tree is on a slight incline.
The photo with the green shoot was taken in May, the later one was in August this year. Any advice would be greatly appreciated.
