Should I rotate flowers to different areas in my garden each year?

Crop rotation - planting a particular plant in a different location each year - is a good gardening practice. When you grow the same type of plant year after year in the same spot diseases and insect problems often develop. To avoid problems it's wise to grow something different periodically to break the pest cycle. On the other hand, if you're having success with a certain variety of flower, you could continue to grow it until a problem occurs, then switch to something else.
