Ive just started to trim back the laurel hedge and got covered in a shower of extremely fine white dust.
On closer inspection the leaves are covered in large (10p) fairly round shaped blotches of powdery white mould(?). The exposed part of the leaves are less effected but the further in I go, the more the whole leaf is covered.
Any ideas what it is and how to treat it?
