Most likely cause
Light is the most common driver of curling in a Chinese Money Plant, and this plant is unusually expressive about it. Too much intense direct sun or a hot, bright spot makes the leaves cup upward into the classic dome shape to shield themselves, while too little light makes them stretch and the leaves curl downward and droop as they reach for more.
Confirm it by reading the curl and the growth. Upward doming next to a sunny window almost always means the light is too strong, especially if the leaves also feel warm or look bleached. Downward curl paired with leggy stems and small, pale new leaves means the spot is too dim. Move the plant to bright indirect light and the new leaves should emerge flat and well-coloured within a few weeks.
Other causes
These rank below light but often overlap with it.
- Watering problems. Underwatering curls the leaves with dry, bone-dry soil; overwatering causes a soft downward curl with yellowing and soggy soil. Let the top inch dry and water when the top 1 to 2 inches are dry.
- Temperature stress. Sudden swings or cold drafts from doors, AC, or vents make leaves curl and droop; keep the plant in a steady 65 to 75F (18 to 24C).
- Low humidity. Very dry air gives crispy, curling leaf edges; this is a minor cause, but lifting humidity toward 50% helps if your home runs dry.
- Normal new-leaf curl. The newest leaves emerge slightly curled and flatten as they mature; if only the youngest leaves curl, this is normal and needs no action.
How to fix it
- Read the curl direction. Upward doming means too much light or heat; downward curl means too little light or overwatering. Let this guide every other step.
- Adjust the light. Move the plant to bright indirect light, out of harsh direct sun but well away from dim corners. An east window or a few feet from a bright window is ideal.
- Check the soil. Feel the top inch or two. Water thoroughly when it is dry; hold off while it is still wet to avoid soft, droopy overwatering curl.
- Stabilise the temperature. Keep the plant in a steady 65 to 75F and away from cold drafts, heaters, AC, and vents that cause sudden swings.
- Lift humidity if needed. If the air is very dry and edges are crisping, raise humidity toward 50% with a nearby tray of water or a humidifier.
- Feed lightly in growth. During spring and summer, feed at quarter strength every few weeks to support healthy, flat new leaves.
- Leave new leaves alone. Let the smallest, youngest curled leaves mature on their own; they flatten naturally.
| Cause | Tell-tale sign | Fix |
|---|---|---|
| Too much light | Leaves dome upward, may look bleached | Move to bright indirect light |
| Too little light | Downward curl, leggy stems, pale new leaves | Brighten the spot, avoid dim corners |
| Underwatering | Curl with bone-dry soil, limp leaves | Water thoroughly, then when top 1 to 2 inches dry |
| Overwatering | Soft downward curl, yellowing, soggy soil | Let top inch dry, improve drainage |
| Temperature or draft stress | Sudden curl near a door, vent, or AC | Keep steady at 65 to 75F, away from drafts |
