Too much sunlight, probably. The plant is curling inward to reduce the surface of the leaves that gets hit by sunlight. If it curls outward it’s the opposite.
Thanks, I’m gonna move it :D. Any Idea why it would primarily do that on the back leafs? The front should get more sunlight.
It’s hard to tell from a picture, but it could still mean it’s underwatered. How frequent do you water it and how much water do you give it?
Also, which direction is it facing and how close to the window is it?
The last weeks/months water should have been fine, but she definitely had some dry stretches last year. The window is like half a meter away and facing south (although the plant itself is facing east).
Should be okay. I would definitely experiment a bit with less sun and more water to see if that improves it!
Yeah my Pilea constantly did this and other more wacky curling. I moved it further away from the sun so it got indirect light and it liked that better.
Damn, I have both inwards and outwards curling leaves on my plant
It could also mean a lack of water if they are curling, but I think it’s a different kind. Lack of water is more like a droopy folding, while the curling as shown in OPs picture is like the leaves are rolling up
