Magnolia Disease

Question

I have a couple of problems with a beloved Magnolia tree. It appears to be two different types of disease. One giving the leaves a lacey appearance which spreads to the whole leaf; the other rust coloured spots. The tree is well watered and drained, shaded from wind and flowered well this summer. Any advice gratefully received.

Answer 1

Most likely fungal leaf spots which don't require any intervention. Just pick up the fallen leaves and discard them in the trash so as not to spread the fungus.
