Do you have a picture? If getting yellow leaves it could be a watering issue. The leaves foldedup before? Where was it when the leaves would fold?

It seems that prayer plants are happiest when left alone, not moved, not in drafts, not too much sun, and out of the way of normal household traffic. In summary, they are picky. If the plant looks fine to you otherwise, then I would try not moving it around for a while and only pay attention to it when watering.

Welcome to the world of the prayer plant. I've been there several times. You buy a pretty maranta. After a few weeks: yellow leaves, dried leaf tips, etc. I'm thoroughly convinced unless you can simulate the rain forest on your home that you will have some type of problem. Tip:. They cannot be in direct sun. Best spot is indirect, bright window. Watering is also a challenge. Overwatering can cause yellow leaves but underwatering causes dry leaf tips. Best bet: Water when the first inch of soil is dry. PS. Don't feel bad. You are not alone, it is difficult finding the right balance but it is possible. Just takes time. :)

Are you still spraying the leaves? I seldom spray the leaves as it can cause problems with fungus and it only last for a brief time anyway. For humidity use a pebble tray ( the tray is filled with water but not above the level of the pebbles, so the pot never sits in water) and group it with other plants with similar humidity needs.
