Lancashire, United Kingdom
I have a Kilmarnock willow which I rescued from a well known DIY/Garden Centre store that was practically on its last legs. It's now a thriving mini tree with plenty of lush new growth. Unfortunately this morning I noticed that it has a rusty orange substance on some of its new branch growth and also on the underside of some older leaves. Can anyone tell me what this is and the remedy if any.
