I have an old willow tree in my garden which historically has been quite magnificent, however this year it didn’t leaf up as abundantly as in the past and by late August had shed all its leaves. There was no sign of blight or canker. A few days ago, on the north facing side of the tree, masses of honey mushrooms have sprouted up. Is anyone able to offer advice on what I should do ? Obviously, as the tree has never shed it leaves so early not grown mushrooms on it’s tree trunk then I suspect the two are connected.
