The leaves on our plants that were planted last fall are turning yellow. We replaced one this spring and some of its leaves are turning yellow. We water and fertilize but doesn't seem to help. We have huge ones in the backyard we planted 7 years ago and they are fine. They are in bloom right now and no yellow leaves. What could be the problem?
