Rose of Sharon wilting
We planted two Rose of Sharon on each side of our front stoop in spring of 2005. They both did well the first two summers. This year, one is great, and the other one looks like it's dying (wilting, leaves drying up). We added lots of good topsoil when we planted them. Upon reading about Roses of Sharon and their problems, I read nothing that relates to this symptom. Any idea what could be killing the one shrub? We did spray for ants around the foundation of house very close to both shrubs.
