Growing Conditions

This type of peperomia is suitable for containers and hanging baskets. The most essential factor to consider is drainage. As said before, make sure there are some holes in the bottom of the pots.

Watermelon Peperomia can grow healthy in any commercial potting soil or DIY mixture that contains loam, peat moss, and compost. This easy-growing plant will not be a hassle to deal with.

The use of sand or vermiculite will give the great drainage it needs. It is better to avoid using the overly-fertile soil. Thus, it would make the peperomia grow excessively.

Sun Requirements

Watermelon Peperomia grows the best in indirect sun exposure. If you expose it with too much lighting, the beautiful bright shade will fade. It will not be something you expect on this houseplant.

Indoor seems to be the perfect place for the plant. If you have a window with exposure from the east, that would be perfect. 

Moreover, for outdoor gardening, you have to make sure the plant is located in filtered light.

Watering Tips

As a tropical plant, peperomia is prone to stem rot in wet soil. So, it is important to water it deeply. Do it when you feel the soil surface a little bit dry. After watering, let the container drain completely.

Even though it needs soggy soil, it does not mean you can let the plant stand in water. If you have the plants outdoors, check them every day in warm weather. 

During fall and winter, give more time to spare in between to let it dry a bit more. When the summer hits, set the pot on a humidity tray with wet pebbles.

Cold Temperature in Winter

Watermelon Peperomia cannot handle really cold conditions. So, if the plants are outdoors during warm weather, place them all inside the house at night. 

Therefore, the temperature would drop drastically on a winter night.

Although Freezing temperatures will kill the plant, it is still able to handle cool weather. If the temperatures are below 50 F, the leaves will start to drop one by one.

Minimum Fertilization

Watermelon peperomia does not need to feed much. It is a light feeder houseplant. Absorbing too many nutrients will make it growing excessively.

It will lose its beauty since it will be a leggy, spindly plant. Besides, minimum fertilization is very important.

If you give the plant a lot of fertilizer, you will not be getting the compact, bushy plant you want. The best frequency for that is once in summer and spring.

Use the balanced, water-soluble product. The granular one would be too strong for the peperomia.

Pests and Diseases

It is an essential aspect to know about any plants. In fact, Watermelon Peperomia does not have any serious diseases. 

However, spider mite, whitefly, and mealybug infestation can be a dangerous threat to the plant.

To deal with those pests, just remove them physically. Using a jet of water is also appropriate. Another thing you can do is to provide great ventilation in the area where you place the plant.


In order to deal with the problems, do some troubleshooting to the plant regularly. Check out the leaves, it will be looking a bit dull or washed out when the plant gets sunburned.

When you see the lower leaves dropping, it needs watering right away. It is better to place it in a small bowl full of water.

If you find the tips of leaves growing brown, it means you give too much water. So, stop the watering schedule for a couple of days.
