Hampshire, United Kingdom
hello, i have a small salix tree in my front garden. it has been there for 7 years nearly. this year i noticed that all the branches have some sort of algae on them. a friend said this hapens when its dry and warm. he said that there was something i could spray on that would bring it back to normal. can you help and do you know what that might be?
