The fastest way to propagate your peperomia is by getting cuttings. Cut an inch of a stem with a leaf on it and put it in a small container with potting soil. • Insert the cut part into the soil and then cover the entire pot with plastic wrap. Doing this will keep the moisture in. • Be sure to water the cutting consistently and be careful that the soil never dries out. Roots will emerge in a few weeks. • Once you see the roots, transplant your peperomia into a bigger pot.
