How to care for Watermelon Peperomia
Peperomia argyreia · Piperaceae
One of the most charming small houseplants: rounded leaves striped silver and green exactly like a watermelon rind, held on red stems. It stays compact and is listed as non-toxic to cats and dogs. Slightly fussier about watering than other peperomias, but not difficult once you find its rhythm. Water roughly every 7 days while it's growing (about every 13 in winter), give it bright, indirect light, kept above 59°F (15°C) — average room humidity suits it.
Care at a glance
Water when the top few centimeters are dry; the leaves go subtly limp when thirsty, and firm up within a day of watering.
Bright indirect light near a window keeps the watermelon pattern crisp; direct sun fades and scorches it.
Quarter- to half-strength balanced fertilizer monthly in the growing season.
Mistakes that kill this plant
- Overwatering, which melts the petioles and crown almost overnight.
- A big deep pot of heavy soil around its tiny root ball.
- Cold, wet conditions in winter.
Seasonal tips
- Keep it in a smallish pot; it flowers and looks best slightly snug.
- Propagate spare leaves in spring: even half a leaf can grow plantlets.
- Reduce watering noticeably in the darker months.
