Hi everyone! I purchased a small peppermint plant and transplanted it into a 6 inch pot. I realized that is probably too small and will be purchasing a new larger pot for it this weekend. It has been doing okay and then today I came home and the stems have started to turn brown. It’s set in a place where it gets full sun for about 6 hours. I did some research but it didn’t look like the fungal infection because there aren’t any yellow spots on the leaves. We are having a huge heat wave now where it’s getting up to 95 or higher during midday. Is it the heat or an infection?
