I divided some peonies 2 years ago and they haven’t bloomed since – neither last year, nor this year. Did I do something wrong?
Peonies are notorious for going extended lengths of time without blooming, especially following division or transplanting. They can go up to four years until they bloom again. They are exceptionally hardy, but sometimes take a little while to get their bearings after the roots are disturbed.
One thing to check, however, is the depth at which they are planted. The fleshy part of the roots should be only 1 to 2 inches below the soil surface. If planted any deeper, the plant will not bloom at all. If they are at the proper depth, getting adequate water, and receiving at least 6 hours of sunshine a day, then the best advice is to just sit tight – they will come around.
