Last week I planted two Sundrop plants. They were green when they went in the ground, now the leaves are turning red with white and brown spots. I’m not sure what the heck is going on? They’re in soil that’s quite clay-heavy and they receive full sun. I live in Pittsburgh. We had a really bad thunderstorm the other day... I’m not sure if they received too much water? Any help you guys can provide would be greatly appreciated! Thanks!
