I have a lovely miniature weeping willow in a container. The container stands approx 3ft high and the tree is a foot tall with the branches hanging down the sides of the pot.
Unfortunately the leaves seem to have developed a vivid bright orange powdery disease - it practically covers whole leaves and some twigs. It has only appeared in the last week at the most and is spreading madly.......is it rust or something else?
Please tell me the tree can be saved!!
Any help or suggestions gratefully received.
(I would rather not use chemicals but if i were to remove every infected leaf i doubt there would be anything left )
