What direction is the window facing? How often are you watering it? And what season is it where you live? At first glance, the pot looks like it might be too big for the plants that are in there.

Thank you so much! I will do all the tips you gave me!!

Too much light. Marantas prefer a shaded light and if you get afternoon sun; that's too much sun (tis why it's leaves are curling inward). I would move her to almost a ambient light setting where it's shaded indirect light :) 

Secondly, that pot may be too large. I would recommend putting her in a 4" pot or something that fits around her rootball. 

Lastly, Marantas need distilled or rain water. Tap water is too harsh for them and their leaf tips may brown with hard water :) hope that helped!!!

I keep it at a window that gets sun in the afternoon but nothing very direct. I water it and it gets new shoots but then they don’t do very well. Am I over or under watering?

What am I doing wrong with this prayer plant?
