We have an area of Monarda 'Jacob Cline' on the south side of our house where the plants do not look healthy:
It almost looks like frost damage. Although we had some cool low's earlier this week (low 40's), we did not have any frost.
Does anyone know what is making our Bee Balm look sick?

Have you also had a lot of rain with the cooler temps. The Bee Bal;m may not have adjusted to the sudden cooler wet conditions after the heat.... Just a guess.
