Peony Problems

We suspect that it's too late for your peony, but just in case... do NOT fertilize it at this point. Wait for active growth. Right now it's just trying to survive and feeding will cause it to spend its last reserves on new foliage. Water when soil is dry several inches down. Saturated soil will kill the roots, resulting in wilting. Was the soil amended prior to planting? Organic matter will create air spaces and allow for good drainage. Peonies like soil high in humus. Mulch to mitigate soil temperatures and water levels. The sun/shade balance is fine. Peonies need to be planted fairly shallowly, or they will not bloom.

Not sure what is going on with your peony. Water when soil is dry several inches down. Saturated soil will kill the roots, resulting in wilting. It could also be transplant shock. Hopefully you used a well-draining, commercial and sterile potting soil for the container because native soil compacts too much and the plant was planted at the same level as its original container. The other problem may be that this specific cultivar does better in cool climates and will not adapt to Southern California's mild weather conditions. Suggest you go to the nursery where you purchased it to find out. Other tips: Peonies like soil high in humus or organic material, mulch to mitigate soil temperatures and water levels and provide afternoon shade if the weather turns hot and dry. Peonies need to be planted fairly shallowly, or they will not bloom. Also check out online resources to grow peonies in southern California such as: ilovepeonies.com
