About 6 years ago I took some peonies from my son’s garden. I planted them where there wasn’t much sun and the next year I replanted them in a sunny area. The bush is growing very well; however, they haven’t flowered. What’s the problem?

Try giving the plant some phosphrus-rich fertilizer or add bone meal to the soil around your plant to help encourage blooming.
