Hi GerI have a weeping willow (planted in May) which is now full of this unsightly yellow powder and the leaves seem to be drying up and dying. What is it and is the tree any good or will I have to take it up. Will this disease affect the bulbs I have planted around it?Many Thanks

We have a large hedge of viburnum tinus. Some plants have wilted, the leaves have gone brown and the shrub eventually dies. We replaced these. Now the same thing is happening to a number of them. Is there anything to do to save them as they are 6 years old? What could be causing the problem?
