Hi all

Can anyone help me restore my 25 year old gorgeous money tree plant back to health.

About 18 months ago after bringing the plant indoors from its summer break, I noticed what looked like white dust all over the leaves. Six months later it was still there. So thinking it was dust I sprayed it with water. Made a big mistake didn't I. Since then it has got worse. It is now in the stem of the tree, leaves, root etc.. I used two different fungi remedies and added new soil. It does not want to go away. I recently moved, which I know stresses the plant but it is getting worse.

Does anyone know what this is, what has caused it and how to cure it. It is a lovely big plant and I don't want it to loose it.
