Need help with this watermelon peperomia. I bought her about a month ago at a plant store’s annual sale. She has been dropping leaves. I had her hanging in a screened porch area where she probably wasn’t getting enough sun. And I think I was overwatering her. I have moved her indoors to an area of partial sun. She was hanging outside in the sun at the store but I thought these didn’t need full sun. She is still in her original pot and soil. What can I do for her?
