Why peony bushes grow large and do not bloom at all or blooms very poorly with just a fewer flowers on the entire bush. The standard explanation may be fine for beginners, but I also know that when planted correctly, peonies very often do not bloom also. It is known that the pieces of roots remaining in the ground after transplanting a peony at a depth of even 30-40 cm can regrow again and form a bush and bloom on their own after 2 years. And sometimes properly buried buds can be on the surface when the soil is washed out or eroded and require hilling and adding soil. In short, the plant can choose a comfortable position for optimal growth and flowering even on its own.
