I was given some spirea plants recently. They were in rough shape when I got them and since they've been planted the leaves have begun to turn brown and fall off. The plants are now in various stages with some still having a few green leaves, the rest having all brown leaves. I assume this means the plants are dead and I should get rid of them.
