Watermelon peperomia care: watering, light and repotting
Also called watermelon plant · Peperomia argyreia · Piperaceae family
14 d in winter
How often to water the watermelon peperomia?
Allow about 8 days between waterings in spring and summer, and 14 days in autumn and winter, when growth slows down. These rhythms apply to a room with its favourite light: in a darker room the plant drinks less; in a brighter one, it drinks more.
Its fleshy leaves store water: let half the pot dry out between waterings.
What light does it need?
The watermelon peperomia likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Repotting and fertiliser
Repot every 3 years, ideally in April, into a pot only slightly bigger than the last one. As for fertiliser, from April to September, feeding every 30 days is enough; the rest of the year, let it rest.
Adult size: 8–12 in (20–30 cm).
Safe for cats and dogs, according to the ASPCA.
Common problems
Soft stems collapsing
Cause: Too much water. What to do: Let it dry out and water less often.
Leaves curling up
Cause: Thirst or very dry air. What to do: Water it and keep it away from radiators.
Frequently asked questions
How often should you water the watermelon peperomia?
About every 8 days in spring and summer, and every 2 weeks in autumn and winter, in a room with its favourite light. The darker the room, the longer you wait between waterings. Before watering, check that the top inch of soil has dried.
Where should you put the watermelon peperomia?
The watermelon peperomia likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Should you mist the watermelon peperomia?
There's no need: indoor air suits it. Wetting its leaves for no reason can even encourage disease.
When should you repot the watermelon peperomia?
Every 3 years, ideally in April, or sooner if roots come out of the drainage hole. Choose a pot only slightly bigger, 1 to 1.5 in (2 to 4 cm) wider, always with a hole in the bottom.
Cats, dogs, children: is the watermelon peperomia safe?
The watermelon peperomia is listed as non-toxic to cats and dogs by the ASPCA. A pet that eats a lot of it may still vomit, so it's best not to let it nibble.
Is it an easy plant to care for?
Yes: the watermelon peperomia forgives a missed watering and adapts well to the home. A good plant to start with.
These are guidelines for an indoor plant in a temperate climate. Trust the soil too: a finger pushed an inch into it will tell you whether it's thirsty.
