I have some wild mint under a couple T-8s that I'm attempting to carry through the winter. Discovered these spots beginning to accumulate on the leaves.

Any ideas?

These plants were in rough shape when I dug them up two weeks ago. Wondering if I should just chop them back to soil level, and let them re-sprout.
