2. Watermelon Peperomia Care & Growing Requirements

  • Watering

The Watermelon Peperomia thrives with moderate watering, so make sure to allow the top of the soil to dry out between waterings.

From personal experience, bottom watering every two weeks or when the soil feels dry to the touch has worked wonders.

  • Light

Bright, indirect light works great for this peperomia. Itโ€™s also important to strike a balance โ€“ while direct sunlight can scorch the leaves, too little light will dull the watermelon patterns.

  • Soil

For soil, a mixture that promotes good drainage is best. A blend of peat and perlite is recommended as it allows for proper aeration and moisture retention.

  • Temperature

The ideal temperature range for Watermelon Peperomia is between 18-26ยฐC. Keep the plant away from areas with drafts or sudden temperature changes, such as near air conditioning units or heaters, as this can stress the plant.

  • Humidity

Moderate humidity suits this plant well. If your house is on the drier side, you can increase the humidity levels by using the popular pebble tray method or grouping plants together. However, make sure not to overdo it, as excessive humidity can lead to issues such as mold or pest infestations.

  • Fertilizer

During the growing season (spring and summer), fertilizing every 2-4 weeks with a diluted liquid fertilizer can benefit the Watermelon Peperomia.

3. Watermelon Peperomia Maintenance and Propagation

  • Repotting

Repotting can be done every 2-3 years. The Watermelon Peperomia prefers to be somewhat pot-bound, which promotes better growth. When repotting, choose a pot only slightly larger than the current one and use fresh, well-draining soil mix. The best time for repotting is during the spring, which aligns with the plant’s natural growth cycle.

  • Pruning

Pruning is mainly for aesthetic purposes. Regularly removing dead or yellowing leaves helps maintain the plant’s health and appearance. Occasional trimming can also encourage bushier growth.

  • Propagation

Propagating Watermelon Peperomia can be done through leaf cuttings or division.

For leaf cuttings, select a healthy leaf, cut it with a bit of stem, and plant it in moist soil. Keep the soil slightly damp and in a warm, bright area without direct sunlight for root development.

Division is best done during repotting. Simply separate the plant into smaller sections, ensuring each has roots, and plant them in individual pots.

4. Common Issues

  • Leaves Turning Yellow: This usually indicates overwatering. Adjust the watering schedule as needed.
  • Leaves Turning Brown: Brown leaves can be a sign of too much direct sunlight or improper watering.
  • Drooping Leaves: If the plant appears thirsty, bottom watering is a quick fix.
  • Curling Leaves: Curling may occur due to excessive light or low humidity.

5. Watermelon Peperomia Diseases & Pests

Common pests include mealybugs and aphids. Overwatering can lead to root rot, so ensure the plant is not sitting in water.


The Watermelon Peperomia is a resilient and attractive indoor plant. It’s surprisingly sturdy despite its delicate appearance. With proper care and attention to its moderate watering and lighting needs, it can be a vibrant addition to any indoor gardening collection.
