Q.Why the leaves of my prayer plant turn yellow?
I water the plant twice a week, as soon as thee soil has dried completely. It isn’t exposed to sunlight directly. I spray the leaves with water for extra moisture 3-4 times a week. However, some leaves keep turning yellow, but new leaves keep growing back.
