My son moved into a new house 3 years ago and was the only one who had a tree planted in the street. Unfortunately we don't know the name of the tree, as his garden is small we assume it won't grow that large. After 3 years it has grown and now has a nice canopy and lovely dappled shade in one corner.
The problem he has with it that it seems to drop some sort of sap and his bench and slabs look dirty underneath, also he has noticed when sitting on the bench that there are a lot of bluebottles, wasps etc in the tree and underneath, I know we have flies etc in gardens but he says these seem unprecedented amounts, he's got to the point that he's thinking of having it cut down as it's really awful!! Anyone any ideas please.
