Peperomia Care
The short answer
Peperomia is a large genus of small, easygoing foliage plants (also called radiator plants) whose thick, fleshy leaves store water like a succulent. Clemson Extension notes that because of those water-storing leaves they need less frequent watering, and if overwatered they drop their leaves.
Give them bright indirect light from an east or south window, a well-drained potting or cactus mix, and let the top of the soil dry before watering again. Root rot from staying wet is the most common problem.
They rarely need repotting and can stay in the same pot for years, and they are simple to multiply from stem or leaf cuttings.
Light
Clemson Extension recommends bright indirect light from an east- or south-facing window; peperomias also tolerate the dimmer light near a north window, though growth and variegation are stronger in brighter light. Keep them out of harsh direct sun, which can scorch the leaves.
Water like a succulent, not a fern
The single most useful fact about peperomia care: the thick, fleshy leaves act as water storage, so the plant behaves more like a succulent than a thirsty tropical. Let the soil dry between waterings and empty the saucer after watering so the pot never stands in water.
Clemson Extension is direct that overwatering is the leading problem and that an overwatered peperomia will drop its leaves, with root rot the most common cause of decline. When in doubt, wait a day. See watering-houseplants for judging soil moisture reliably.
Soil, potting, and humidity
Use a well-drained houseplant mix or a cactus mix. Peperomias have small root systems and dislike being over-potted, so they can remain in the same container for years and rarely need repotting; when you do, go up only one pot size (see repotting-houseplants).
Average indoor humidity is fine, though a little extra humidity helps in dry winter months. If your home runs very dry, see how-to-increase-humidity-for-houseplants.
Feeding and propagation
Feed only during active spring and summer growth with a diluted liquid fertilizer, or use a slow-release product once a year; these are light feeders.
Propagation is easy. Clemson Extension describes stem cuttings, leaf cuttings (including the petiole), and water rooting for types like the baby rubber plant. For general technique see how-to-take-cuttings.
