Brown Spots on pilea peperomioides
What's Happening
Direct sunlight exposure. Pilea peperomioides has thin, peltate leaves with an underdeveloped cuticle that cannot handle the thermal load of direct UV rays, leading to rapid cell death (necrosis) appearing as black or brown spots.
How to Fix It
- 1
Move the plant immediately to a location with bright indirect light (e.g., 2-3 feet away from a window or behind a sheer curtain).
- 2
Trim severely blackened leaves to stop the spread of opportunistic fungi in dead tissue.
- 3
Monitor new growth; if it comes in healthy, the location is correct.
How to Prevent It
Avoid placing Pileas in south-facing windows without protection. Aim for 2000-5000 lux of indirect light.
