& died. The plant is not completely dead, it is still trying to grow, but the leaves are smaller with not much mint flavor. I water plant at the base instead of on top to keep down gnat infestation. What to do to save the plant?

I would cut it way back, just a few inches from the soil, to remove most of the pests and disease.

Then you can spray the remaining leaves with Neem oil, which should help with pests or fungal disease.
