Peperomia is one of the two large genera of the Piperaceae family, with more than 1000 recorded species. Most of them are compact, small perennial epiphytes growing on rotten wood.
Peperomia plants grow well in the bright indirect light provided by a west or east-facing window. These plants even grow under fluorescent lights. Insufficient light causes the slow-growing peperomia plant to stop growing altogether. Direct sunlight burns the leaves.
Allow the top 50% of the soil to dry out before you water. Over-watering, resulting in root-rot, is the main cause of serious peperomia plant problems. It’s best to water these plants from the bottom. This technique keeps the leaves dry and helps prevent plant diseases. The thick leaves of peperomia plants hold water and allow the plant to withstand long periods without moisture.
Warm temperatures between 60°-80° F are best. Temperatures below 50°-55° F and cold drafts from windows and doors damage peperomia plant leaves.
