Loads of flies and leaves shedding off Salix Kilmarnock
Hi, I purchased two Salix Kilmarnock trees in April, they have grown so well, although not had the white fur bits on end. Recently, the leaves had started to go brown, crispy and fall off but so have other leaves which aren't brown and crispy. I've noticed in the last two days the leaves that are on the tree, are swarmed with flies, they are like blue bottles. Is the tree dying? Should the leaves be shedding? How do I get rid of the flies?
