Few things are more alarming than watching your Pilea peperomioides — the Chinese money plant, pancake plant, or UFO plant — start shedding leaves. The good news is that Pileas are dramatic communicators: leaf drop is almost always a fixable response to something in their environment, not a death sentence.
Here are the most common reasons a Pilea drops leaves, and exactly what to do about each one.
1. Overwatering and root rot
This is by far the most common cause. Pileas store water in their thick stems and coin-shaped leaves, so they hate sitting in soggy soil. When the roots stay wet too long, they begin to rot — and the plant sheds leaves (often yellowing first, starting from the bottom) because damaged roots can no longer support them.
The fix: Let the top inch or two of soil dry out before watering, and always empty the saucer so the pot never stands in water. If the soil is staying wet for days, slide the plant out and check the roots — healthy roots are firm and white, while rotten ones are brown, mushy and smelly. Trim any rot away and repot into fresh, well-draining soil. Our guide on saving an overwatered Pilea walks through the rescue step by step.
2. Underwatering
The opposite extreme causes trouble too. A Pilea left dry for too long will droop, its leaves will curl, and eventually the lower ones drop as the plant conserves resources.
The fix: Check the soil with your finger — if the top few inches are bone dry and the leaves look limp, give it a thorough drink until water runs from the drainage holes. For a full routine, see how often to water a Pilea.
3. Cold drafts and temperature swings
Pileas are comfortable in normal room temperatures (around 60–75 °F / 16–24 °C) but dislike sudden change. A spot next to a drafty window in winter, an air-conditioning vent, or a heater can chill or dry the plant enough to trigger leaf drop.
The fix: Move the plant away from drafts, vents, and cold glass. Aim for a stable, moderate temperature.
4. Environmental shock
Just brought your Pilea home, repotted it, or moved it to a new room? A burst of dropped leaves in the days afterward is often simple acclimation shock. The plant is adjusting to new light, humidity and temperature.
The fix: Resist the urge to fuss. Keep care consistent, give it a stable spot with bright indirect light, and let it settle. Most Pileas recover on their own within a week or two.
5. Too little (or too much) light
In low light, a Pilea grows leggy and sheds its lower leaves as it stretches toward the window. In harsh direct sun, the leaves can scorch and drop instead.
The fix: Give it bright, indirect light and rotate the pot a quarter-turn every few days so it grows evenly rather than leaning and dropping leaves on the shaded side.
6. Natural aging
Sometimes there's no problem at all. Pileas naturally shed the occasional old leaf from the bottom of the stem as they put out fresh growth on top. If it's just one older, lower leaf now and then — and the new growth looks healthy — that's completely normal.
7. Pests or overfertilizing
Less commonly, sap-sucking pests (like spider mites or fungus gnats) or a buildup of fertilizer salts can stress the plant into dropping leaves. Inspect the undersides of the leaves for pests, and only feed with a diluted houseplant fertilizer during the growing season — never a struggling plant.
The bottom line
Work through the list from the top: check your watering first (it's usually the answer), then look at temperature, recent changes, and light. Once you've matched the symptom to the cause and corrected it, a healthy Pilea bounces back quickly. For everything else about keeping this plant happy, see our full Pilea peperomioides care guide.
