Prayer Plant Leaves Getting Brown Edges and Curling. Hi Judy I have a tricolor prayer plant Iâve done everything they have said bout care and the edges of the leaves are getting brown and curl. There are several reasons why Prayer Plant leaves get brown edges and curl. A Prayer Plant likes a very humid environment and the humidity in ours homes is often too low. You can increase the humidity by grouping plants together, putting a small humidifier or bowl of water near the plant, or setting a Prayer Plant on a tray filled with water and small stones or pebbles. Be sure the plant is sitting on the pebbles and not in the water. Other causes are: the leaves of your plant may be touching the cold glass of the window: too much plant food. Prayer Plants should not be fertilized very often since excess plant food can cause brown edges. Always dilute the plant food to 1/2 the recommended strength.
