Why are my peonies not doing well?

I have a peony bed which does get full sun, these plants have not bloomed for several years and I know peonies are usually low maintenance. Any suggestions to help with my sick bed? I live in Three Rivers, MI.

Hi, Well if you are sure they are getting enough sun, then it could be a couple of other things. Problem is, I don't have all the information I need. If, they have been in the same place for many years it could mean they are overdo to be divided. Although peonies can go years without division, they do best whend divided every 5 or 6 years. So, perhaps if your plants are quite old, they need to be divided. Fall is the ideal time to dig an divide them. Or, if you just planted your peonies a year or so ago, it could be that they are too young to bloom well. It often takes a couple years for a peony to put on a show after planting. Or, it could be, if your plants are on the young side that they were planted too deeply. Peony roots should be planted just an inch or two below the surface of the soil. If planted much deeper they might not bloom at all. Or, they are older plants that haven't been fed for a long time. You don't say if you've fertilized these plants or not. Peonies benefit from a yearly sprinkling of slow-release dry, granular fertilizer in the early spring just as they pop out of the ground. Again, lack of flowers could be caused by a number of issues. I just don't have enough information to go on here. And, I just have to remind you that the number one reason peonies don't bloom is lack of sunlight. Be sure your planting bed gets at least 6 to 8 hours of direct (not filtered) sunlight per day.
