Grow peperomia in a medium or bright spot to keep the plant happiest. They can tolerate low light, but don't grow as well and their foliage may not be as interesting.
Water peperomia when the soil feels dry to the touch. Many varieties of this small houseplant can effectively hold water in their fleshy stems and leaves during times of drought, so they can hold their own if you forget to water or go on vacation.
You don't really need to fertilize peperomias, but you can if you'd like these easy-to-grow houseplants to grow a little faster. Use any fertilizer made for indoor plants and follow the directions on the packaging.
Because peperomias don't grow very fast, you don't need to worry about pruning them.
Note: Peperomias are not meant for animal or human consumption.
