Peony Irrigation Guide: Learn How Much To Water Peonies

The amount of water needed for peonies depends on many factors such as the type of soil, size of the plant, climate, etc. The following table gives some general guidelines. If you are concerned with specific requirements, consult your local extension service or visit a nursery to get advice.
