Grown for their ornamental foliage, Peperomia argyreia are a small plant, which is an excellent choice for uses in semi-shade, as it will thrive with regular watering, but also requires well-draining soil to ensure that the roots never sit in overly wet or boggy soil.
Native to South America, Watermelon Peperomia is hardy in USDA Zone 10-12, and they are very easy to grow in the right conditions. If a colder climate presents itself, plants can still be grown in pots, however careful attention and frequent monitoring will be required to adjust care due to weather fluctuations and seasons. When growing in pots for colder climates, it is important to keep an eye on soil moisture, as potted plants dry out more quickly than plants in the ground. While Watermelon Peperomia can handle drought for some time, consistent and regular watering is required in order for plant to thrive, as well as providing good drainage and a partially shady location.
Furthermore, it's important to perform regular pruning to keep the shrub looking its best, as well as removing any damaged or dead leaves to promote healthier growth. Due to low nutrient needs, this plant requires limited fertilization. For best results, use a balanced fertilizer rich in micro-nutrients and potassium, and water the plant after fertilization to avoid damage to the roots.
Ultimately, Watermelon Peperomia is an excellent choice for a variety of uses and landscaping, thanks to its beautiful foliage and demanding minimal care. With regular monitoring, this plant will thrive under the right conditions and bring beauty and life to semi-shaded areas in most USDA hardiness Zones.
