The prayer plant has the ability to fold its leaves up at night, resembling hands clasped together praying. The lesser-known name of the prayer plant is the genus Maranta leuconeura (Marantaceae). The plant grows very well as an indoor plant with the proper temperature, watering, feeding and light conditions. The plant is native to Brazil and blooms in spring and summer with little white flowers with purplish spots. The oval leaves are about 8 inches long and 4 inches wide.
Keep the plant in a shady, but warm place. Indirect sunlight from an east or west window will keep the plant warm. The ideal temperatures will be between 60 degrees and 80 degrees Fahrenheit.
Mist the leaves several times a day so the plant has enough humidity, which it needs to grow and flourish. In its native Brazil, the plant grows in tropical conditions. Place a drainage tray under the pot with gravel in the tray to collect the runoff after watering. This will provide more humidity.
Water the plant when the soil---which should be one part sand, two parts peat and one part loam---becomes damp to the touch during spring, summer and fall. Allow the soil to become dry during the winter months before adding water.
Feed the plant once a month with 10-10-10 plant food, which has equal parts of nitrogen, phosphate and potassium. During the later fall and winter, feeding should stop; start again in April.
