Watering Watermelon peperomia must be allowed to completely dry out between watering. Peperomia have very fine delicate root systems. Do not allow to stay wet constantly.
Growing Spring and summer is growing season. They will flower in winter.
Potting: Keep peperomia in a plastic nursery pot and sit inside a cover pot unless growing outside. To help avoid rot issues, you may prefer to plant into a terracotta pot. This helps to dry the potting mix quickly.

Watch out Watermelon peperomia must be grown in a very bright, indirect light position. Just off to the side of a window is suitable and early morning sun is ok.
Allow peperomia to completely dry out between watering. Watch for them to droop a little before watering. Feel the foliage, it will feel slightly soft when needing water.
If there are black marks on the leaves or rotting stems, reduce water frequency. Try and purchase a reasonable sized plant. This will ensure you start with a decent root system.
