The Ideal Soil for Peonies
Peonies love moist and rich organic nutritious soil. It should also be taken into consideration that on clay soil the harvesting of roots is much more difficult than on sandy soil. Clean roots are a big advantage and will save a lot of time.
On the other hand, the main advantage of clay soil is that the roots grow bigger and much faster due of its high nutritious character. It’s all a matter of priorities.
