Magnolia Disease

Zone DH1 2SH | Anonymous added on August 24, 2019 | Answered

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.

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.
