How deep do itoh peonies need to be planted?
This is my 15 gallon itoh peony which has 16 stems, and I plan to split it into 4 by around fall, and plant them into the ground. When is the best time to split it?
How deep should I put them? This is the Keiko pink type, and this type of itoh peony produces all woody stems so I'm guessing that it probably behaves just like a tree peony. My goal is to make it produce as many new shoots as possible so I'm wondering if it will help to plant it deeper.
