Two years ago I had to remove two peonies after having them for almost 25 years. They were in an area between the front sidewalk and the house. They were beautiful for many years but finally stopped doing well. Last year I planted replacement peonies I bought from a local greenhouse and they didn't do very well either. Only one of the two came up this spring and it looks very small. I have tiger lilies in this same garden and they do very well. Is it possible that the 25 year old peonies finally depleted the soil in this area? I've heard bone meal is good when planting peonies but couldn't find any when I put the new plants in. Any ideas on how to get peonies to grow again in this area.
