Problems with Quince
I have a large quince tree but rarely get to eat any of the fruit as it suffers very badly with brown rot. I religously pick off infected fruit as soon as I see it. I pick up and burn all the leaves and keep the area under the tree clear but the problem is geeting worse. Is it because the tree branches are covered in lichen and this is harbouring the spores? It is far too big to scrub free of lichen. Any thoughts please?
