When growing a Peperomia, locate the plant in a medium to low light situation that does not get direct sun. You may also grow Peperomia plants under fluorescent lighting.
Grow Peperomia plants in a light houseplant mixture with perlite or coarse gravel included to allow roots to receive air circulation, necessary for the health and development of your plant. If your peperomia plants are wilting, in spite of regular watering, the plant is likely not getting enough oxygen to the roots.
Water Peperomia houseplants sparingly and allow the soil to dry as deep as 5 inches between waterings. Fertilize occasionally with a balanced houseplant food after watering.
Leach the plant in summer by flushing with water to remove the salts left behind by fertilization. Repot Peperomias in spring, but keep pots small, unless you are growing Peperomia as part of a container combination.
