Peonies can be fed with Osmocote Plus in late spring just after they bloom. Cut off the faded flowers but leave as much foliage as you can. The remaining leaves make next year's flowers. Remember not to put a mulch or extra soil on top of peonies as they need to be planted shallow or they will produce greens but no flowers. They also hate to be moved. To keep any leaf blight from forming cut peony plants back in the fall once the leaves turn yellow. I see some beautiful blooms in your future. Keep growing, Marianne Binetti
