 Let me show you how to turn this watermelon pepperomia into many pepperomias. First, prepare the pot with all-purpose houseplant pot and mix and add water for humidity. Cut healthy leaves from your pepperomia and then cut them in half, making sure that you cut through the lines on the leaf. Add some cinnamon to prevent fungi and stick your leaves in the soil. Then cover with a plastic bag or a transparent lid. This will maintain humidity inside while letting the sunlight in. Make sure you uncover for an hour every day. This will help with air ventilation and you can also check if you need to add more water. And my friends, you will see roots in a month or so.
