Temperature

• Low temperatures may cause leaves to turn brown and shrivel. It is essential to keep the plant warm in winter.
  
  

Moisture

• The soil should be slightly moist all year. Misting the leaves, particularly if there is little moisture in the air, can help keep leaves green.
  
  

Light

• The prayer plant requires light shade. The leaves of plants in direct sunlight may become bleached, especially during the summer.
  
  

Age

• Prayer plant leaves naturally turn brown with age. If browning is isolated to just a few leaves, it may be from natural aging. These leaves can simply be removed.
