I have a japaneese acer tree 12 years old and have noticed this last few weeks it has developed a type of rust on the leaves and a white powder substance on the stem.Can anyone please tell me what this is,what is suddenly causing it and can i cure it.

Hi Dickvandyke: I googled your problem. It sounds like BOTRYTIS -grey mildew. If you go to www.gardenaction.co.uk/plantfinder/japanese_maple-4.asp, you'll find lots of info on Acers.
Hope you cure your tree, Acer are so lovely.
