Since the plant is Epiphytic, it has thick leaves, and it retains water. As a result, it desires well-draining soil to grow properly.

The best potting mix for this type of peperomia is a cactus mix, which is a mixture of perlite, garden soil, and gravel in a ratio of 2:3:3.

However, you can also thrive it well in a mix of cocopeat and perlite alone as well. It requires the PH of the soil to be acidic.

2. Standard Temperature for Watermelon Peperomia

A Watermelon Peperomia is the happiest in temperatures between 18C to 25C which is equal between 65F to 75F. It cannot withstand cold temperatures, and will not survive temperatures below 10C.

Due to this, you should consider keeping the plant in temperature and climate-controlled greenhouses, or under grow lights with similar tropical flora.

If you expose the plant to extreme cold drafts, the underside of the leaves may start to brown. In case, it is exposed to warm and dry air, the leaves may begin to crack and split on the edge.

So, you should be careful in ensuring a humid ambiance to help the plant stay healthy.

If you plant it in the landscape, it does very well in dappled light situations in a flowerbed. Because, here, watermelon peperomia remains shaded from the harsh sun for most of the day by the canopy of bigger trees, much like how it grows in the wild.

Indoors, the plant prefers to have indirect bright light. And while it thrives in bright light, it will begin to show signs of stress when placed in a darker spot with awfully low light.

Being kept in the dark, your plant may lose its variegation and the leaves will turn into a darker shade of green.
