Know your plant
Peperomia (radiator plant) 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. More than 1500 species have been recorded, occurring in all tropical and subtropical regions of the world, though concentrated in Central America and northern South America. A limited number of species (around 17) are found in Africa.
1. When growing a Peperomia, locate the plant in a medium to low light situation away from direct sun. You may also grow Peperomia plants under fluorescent lighting.
2. 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.
3. Water Peperomia houseplants sparingly and allow the soil to dry as deep as 5 inches between waterings.
4. 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.
