Indoor environments are relatively closed, and water evaporates slowly. Therefore, it's important to manage the amount of water you give your peony. Excessive soil humidity can affect the plant's ability to breathe, leading to leaf and flower dropout.
When growing peonies indoors, light is crucial. If the plant doesn't receive enough sunlight each day, the flowers and leaves will wilt. Place your peony on a south-facing balcony or windowsill to receive diffused light.
