I recently moved to a new house. One of my first things I did, of course, was clean up the flower beds and put in new plants. Some of the new plants are doing very well, but several have leaves that are changing colors. The affected plants are both in the ground and in buckets. The worst hit are my geraniums, gerbera daisies, and salvia, but I have some of each of these that are growing vigorously, as well. The new growth seems to grow normally, then turn as it gets older.

The leaves of the geraniums are turning copper...
