Peperomia is a genus of herbaceous perennials consisting of more than 1,000 species. The plants, which are members of the pepper family, are native to tropical areas. They typically grow about 12 inches in height, but they are widely varied in appearance. Peperomia is commonly grown for its ornamental, usually variegated, leaves. Despite its tropical origins, peperomia can be successfully grown indoors in any climate.
Plant peperomia in a container filled with one part potting soil and one part peat moss for adequate drainage. Keep your peperomia plant in a location that receives bright, indirect sunlight throughout most of the day. Avoid direct sunlight, which could burn the tender leaves.
Keep peperomia plants at a temperature of between 65 and 85 degrees F. Peperomia cannot tolerate temperatures below 50 degrees F for any length of time. Move the plant away from cold or drafty windows in the winter, if necessary.
Water peperomia once every seven to 10 days. Allow the soil to dry out between watering to prevent root rot. Soak the soil during each application to ensure that plenty of moisture comes into contact with the roots.
Mist peperomia with a spray bottle filled with lukewarm water once every three days during spring and summer. Spray only during the morning hours so the foliage will dry out thoroughly before nightfall.
Feed peperomia plant once per month using a 20-10-20 NPK fertilizer. Water both before and after applying the fertilizer to prevent root burn. Follow the instructions provided by the manufacturer for proper application and dosage.
Transfer peperomia to a new planter once every two years to refresh the soil and to prevent the plant from becoming completely root bound. Increase the size of the container by 2 inches each time peperomia is re-potted.
