How to Grow Watermelon Peperomia

Watermelon peperomia can be planted from the leaf or stem cutting. Cut the leaves with stalks (petioles) 2-3 cm (1 inch) and dab it in the rooting hormone before planting. Keep the soil moist and warm.

If you are propagating the plant from stem cuttings, either grow it in soil, the way, you usually do or place the stem in clean water. Change the water every 2-3 days. You will notice new roots emerging from the stem in 2-4 weeks.


Container Size

If you’re growing dwarf watermelon peperomia, a 3-4 inches pot should be fine. For a usual watermelon peperomia, select a decorative 4-6 inches container, it can work for more than a year before the next pot upsize.

Tip: Select one or two sizes bigger pot than the size of the rootball of your peperomia plant. It grows best when it’s slightly rootbound!


Requirements for Growing Watermelon Peperomia

Location

The plant performs well in bright, indirect sunlight. Avoid exposing it to the direct, harsh sun to save the foliage from burning and heat stress, especially in a hot climate. While planting indoors, place the plant on an east or west-facing window. Outdoors, grow the plant in the shade.

Soil

Use any regular houseplant potting mix. You can also prepare your own with the help of some suggested recipes here. Just remember, your substrate must be loamy and well-draining.

Water

Water the plant when the top 1 inch of soil looks dry and never allow the pot to sit in water. Keep an eye on the outdoor plant in warm weather as it may need more frequent irrigation. During fall and winter, reduce watering.

Temperature and Humidity

This plant cannot withstand freezing temperatures. Bring your outdoor plant indoors when the night-time temperature falls below 50 F (10 C). The ideal day time temperature is 60 F (15 C). If you live in a hot climate, bring it indoors when the temperature starts to exceed above 100 F (37 C).

Watermelon peperomia is a tropical plant, and it loves a humid surrounding. To maintain it, place the pot on a tray filled with water and pebbles. For tips for raising humidity, click here.

Fertilizer

This beautiful specimen is a light feeder. Extra supply of nutrients may result in a weak, leggy, and excessive growth instead of a bushy, compact plant.

Fertilize the plant every 5-6 weeks during spring and summer and every 2 to 3 months in fall and winter (don’t fertilize in winter, if you live in a really cold climate) with a balanced, water-soluble fertilizer. Feed with half or one-quarter strength of the quantity suggested by the manufacturer. Avoid using granular fertilizer!

Repotting

The plant doesn’t require repotting, as it likes to live in a slightly pot-bound state. Repotting can be done after two-three years to 1 or 2 sizes bigger pot during the spring.
