Brown Spots on Japanese Magnolia
I'm cross posting this to see if I get any better response here. I tried on the pest board, but got nothing.
I planted this Japanese Magnolia back in April. It seemed to be thriving until just recently.
It has been pretty wet and rainy the past few weeks, and the other day, I noticed the leaves were looking a little yellower than normal. I looked at them closer, and noticed they were covered in these tiny brown spots that don't rub off of the leaves.
The tree isn't losing leaves, in fact they hold pretty strong when you tug on them. Any ideas on what this is? Is it just cosmetic or is it a more serious disease? Thanks!
