Peperomia Rosso prefers bright, indirect light. It can tolerate lower light conditions, but growth may slow. Water your Peperomia Rosso when the soil is about 50-75% dry. Water thoroughly, until excess water flows from the drainage hole into the saucer, but do not allow your Peperomia to sit in excess water or soggy soil. Peperomia Rosso will tolerate average household humidity. However, like most tropical plants, it will benefit from added humidity.
