Watermelon peperomia care tips

Even though this is a tropical plant, peperomia argyreia is relatively easy to care for. It is tolerant of different light conditions and adapts to the average humidity in most homes.

Here are some growing tips to get the most out of  your plant.

Watermelon peperomia light conditions

In its native environment, the plant receives filtered or dappled sunlight which comes through the dense canopy above, resulting in moderate light conditions.

Indoors, try to provide bright, indirect light. Avoid direct sunlight, which can scorch its leaves.

Readers often ask “Can peperomia grow in low light?”. 

Although it can tolerate lower light conditions, the plant may grow more slowly in darker rooms. The plant will retain its striped pattern even in lower light conditions, but the intensity of the stripes might diminish slightly compared to medium light conditions.

Insufficient light can also cause the leaves of the plant to droop.

Temperature and humidity needs for peperomia argyreia

Maintain temperatures between 65-75°F (18-24°C) during the day. Avoid exposing the plant to cold drafts or temperatures below 50°F (10°C) since the plant is  sensitive to cold.

Although higher humidity is always appreciated by tropical plants, watermelon peperomia can tolerate average indoor humidity levels.

You can increase humidity by misting the plant occasionally or placing a humidifier nearby. Grouping it with other plants, or using a humidity tray, will also raise the relative humidity.

Soil needs

Watermelon peperomia doesn’t like to be waterlogged, so use well-draining soil. If your soil is poor quality, add peat moss, perlite, or sand to help improve drainage.

Regular potting soil mixtures for houseplants work well. Watermelon Peperomia likes to sit in snug pots.

If it becomes too pot-bound, repot in the spring using fresh, well-draining soil.

Watering and fertilizer requirements for watermelon peperomia

Allow the top inch (2.5 cm) of soil to dry out before watering again. When watering, do so thoroughly, but ensure the pot has drainage holes to prevent waterlogging, which can cause root rot.

Drooping leaves can result from both overwatering and underwatering. 

During the growing season (spring and summer), apply a balanced, diluted liquid fertilizer every 4-6 weeks to support growth.

Reduce or stop fertilizing during fall and winter when the plant’s growth slows down.

Pests and diseases

Keep an eye out for common pests such as spider mites, mealybugs, or fungus gnats. Treat any infestations promptly using natural remedies or insecticidal soap.
