Place your Watermelon Peperomia in bright, indirect sunlight. In fact, the peperomia plant even tolerates low light at times.  However, avoid placing the shiny plant in direct sunlight as it can sunburn. Alternatively, if the plant is not provided with enough bright light, it will tend to become leggy. Specifically, stretching itself towards the available light. Definitely prune it back to retain the compact appearance of the plant. Nevertheless, move the plant to a brighter location if this happens.
Water your Watermelon Peperomia thoroughly. In particular, make sure that the soil is evenly moist. If the top 1-2 inches of soil is dry to the touch, then it is time to water. Next, allow water to flow through the pot’s drainage holes. Furthermore, avoid overwatering your plant. Whereas, it will bring about root rot problems.
Alternatively, the plant has almost little to no watering needs in winter. Therefore, water your peperomia plant sparingly. Finally, use a moisture meter if you are unsure.
Watermelon Peperomias prefer high humidity and temperatures from 55° to 80° F (13°-27° C). During colder months with low humidity, set the plant on a pebble tray of water. Or, place it near a humidifier. In addition, the indoor plant is winter hardy to USDA zones 10 to 12. 
Like most Peperomias, argyreia grows best in fertile, well draining soil. Be sure to not use soil that is too compacted or heavy. In fact, this can result in prolonged periods of water retention. Specifically, resulting in root rot. Furthermore, improve the texture and fertility of your soil by adding compost or top soil at planting time. 
During the growing season, Watermelon peperomias will appreciate a diluted liquid fertilizer. Specifically, every two weeks or once a month in spring and summer. However, no feeding is required in the cold, chilly season.
When your peperomia is ready for repotting, be sure to add some fresh potting soil. Additionally, this will replenish the peperomia’s nutrients. Furthermore, repot your Watermelon Plant after it doubles in size, or every 2-3 years.
Genus name Peperomia comes from 2 Greek words. Peperi meaning pepper and homoios meaning resembling. The plants resemble, and are closely related to, true black pepper (Piper nigrum). Furthermore, the specific epithet argyreia means “silvery”. As well as that, common names include the watermelon peperomia or watermelon begonia.
