Mint

Question

Some of the leaves on my mint plant are showing signs that something is happening to the middle of the leaves. The leaves are getting super paper thin in the middles and slightly see through and sheer. I don’t see any bugs or any sign of a powdery mildew. What could this be?

Answer 1

It sounds like fungal leaf spot. If possible, trim away infected leaves and make sure the leaves stay dry. Normally this issue will clear up on its own if you do this. Keep it away from other plants though as it can spread.
