How to Grow Watermelon Peperomia (Peperomia argyreia)

Light

Watermelon Peperomia prefers bright light away from direct. It will also thrive under artificial light. Too little light will result in leggy plants. Keep it away from direct sunshine as it can lead to scorching of the leaves. Learn how to ensure your plant receives the correct light in this guide on understanding light for houseplants.

Water

Water Watermelon Peperomia liberally during the growing season and allow the soil to dry out between waterings. Significantly reduce watering during the cold season to keep the soil barely moist. Avoid waterlogging as it can lead in root-rot. Learn more on how to water houseplants.

Temperature

Average warmth between 18-250C is ideal for Watermelon Peperomia. Protect the plant from cold draughts as they can cause leaf drop. Learn more on temperature for houseplants.

Humidity

Watermelon Peperomia thrives in a high humidity environment. You can employ these techniques to raise humidity for the plant. Watermelon Peperomia can also be grown in a terrarium as high humidity can be maintained.

Feeding

Feed Watermelon Peperomia with a balanced water-soluble fertilizer every 3 weeks during the growing period. Withhold feeding during the cold season as growth is minimal and feeding at this time may lead to fertilizer burn. Learn more on feeding houseplants.

Repotting

Repot Watermelon Peperomia during the growing season only when the plant has become pot-bound. However, the soil can be refreshed at the beginning of the growing season if not repotting. Use a rich, free-draining soil. Use a pot one size larger for repotting as the plant grows slowly. Ensure the pot has a drainage hole to prevent waterlogging which can lead to root-rot.

Pruning

Pruning Watermelon Peperomia involves regular removal of dead foliage to maintain the plant neat and tidy.

How to Propagate Watermelon Peperomia (Peperomia argyreia)

Watermelon Peperomia can be propagated from leaf cuttings or by division.

Propagating Watermelon Peperomia from leaf cuttings
Leaf cuttings root easily, use a rooting hormone to enhance rooting. Take leaf cuttings from a healthy Watermelon Peperomia. Ensure each leaf cutting has a petiole. Allow sometime for the formation of a protective callous tissue over the cuts. Place the leaf cuttings in a jar of clean plain water and change the water every 7-10 days. Place in warm shaded place until growth begins at the base of the petiole. Allow for substantial growth of the roots and new leaves. Transfer to individual pots and place in a cool shaded place. Maintain the soil moist until the plant is well established. For a fuller plant, plant several cuttings in one pot.

Propagating Watermelon Peperomia by division
Take out the Watermelon Peperomia from its pot and divide it into several sections. Pot up these sections in individual pots. Place in a cool shaded place. Maintain the soil moist until new growth emerges. Allow the new Watermelon Peperomias to be well established before transplanting.
