Prayer Plant (Maranta) Plant Profile

The Maranta genus includes a few dozen low-growing plants native to the American tropics. Maranta leuconeura prayer plants have some of the most strikingly beautiful, decorative leaves in the plant kingdom. The popular tricolor variety has deep green, velvety leaves with yellow splotches down the midrib and arching red veins traveling to the leaf margins. A well-grown maranta should have full, 6-inch-long leaves rising from a short center stem and draping down. They are fairly common as houseplants, but not necessarily easy to keep growing over the long-term.

How to Grow Prayer Plants

Maranta are all fairly low-growing, spreading plants with none reaching over about 8 inches tall, making them excellent for grouped displays of low plants on a windowsill.​ They thrive best when provided with greenhouse-like conditions: warm, moist, gentle airflow, and plenty of fertilizer. Plants that are kept too cool or too dry are likely to lose their leaves or suffer from fungal infections that will cause the plant to die from root rot or collapse. Plants that are exposed to too much sun are likely to become washed out and develop brown blotches on their leaves.

Light

You can hang or set your prayer plant near a window where it will get indirect sunlight. Never set your plant in direct sunlight as the sun will scorch the plant’s leaves, leaves will develop blotches or patches and will fade in color intensity. It is generally tolerant of lower light areas. In the winter, when the plants go into dormancy (and sometimes die back completely), give them bright light to maintain growth.

Soil

This plant prefers acidic soil. Use a peat-based potting mix with a pH of 5.5 to 6.0 or mix two parts sphagnum peat moss, one part loamy soil, and one part perlite or coarse sand together. It is best to get only clean, pre-packaged materials that have been commercially processed and are free of insects and weed seeds.

You can also use a general purpose houseplant potting soil, as long as it is well-draining. If you are using soil that does not drain well, add perlite or coarse sand to the mixture. To improve drainage, add rocks or gravel to the bottom of your pot and be sure that the pot has a drainage hole.

Water

During the growing season, water frequently and never allow the potting soil to dry out. Water the prayer plant when the top of the potting soil is just starting to get dry. They are very susceptible to drought. However, to avoid fungal problems, try not to get water directly on the leaves or let it sit or get soggy. Not enough water and overwatering can cause the leaves to turn yellow and drop from the plant. When watering, use water that is at least at room temperature if not slightly warm. In the winter months, reduce watering.​

Temperature and Humidity

A prayer plant prefers normal household temperatures between 60 F and 80 F. Lower temperatures can damage the leaves. A prayer plant likes a very humid environment, and the humidity in homes is often too low. Increase the humidity by grouping plants together, put a small humidifier or bowl of water near the plant, or set a prayer plant on a tray filled with water setting the pot atop small stones. You can also mist the leaves with room temperature or warm water.

Fertilizer

Fertilize your prayer plant every two weeks from early spring through fall. Dilute a balanced, water-soluble houseplant fertilizer (10-10-10) to half strength. If you use too little fertilizer, your plant will grow slowly or hardly at all. Too much fertilizer can burn the roots, leaves will start to brown, and you can even kill the plant. Cut fertilizer back to once a month or so in the winter.

Potting and Repotting

You should not need to repot your prayer plant often. But, if it becomes root-bound or pot-bound, it will grow much slower. If you repot, choose a pot that is only one to two inches wider than the existing pot. During repotting, gently remove the plant from its old container, shake roots clean, and place into a new container with fresh potting soil. Water well.​ Best time to repot is in the spring before the growing season starts.

Propagating Prayer Plants

Propagating prayer plants is surprisingly easy. Some Maranta species can be propagated by stem cuttings or rhizome division. The most common (and easiest) way to propagate this plant is by division at repotting.

  • Division: When repotting, you can divide your prayer plant into several smaller plants by gently shaking the soil off the roots and working them apart. Each new plant should have a good mass of roots and several stems. Pot these new smaller plants up separately in small, shallow pots. Keep new divisions very warm and moist during the first few weeks until new growth emerges.
  • Cutting: Make a stem cutting below a leaf node. Dip the cutting in a rooting hormone and place in a glass of water, making sure to change it every two days or so. Once roots form, add the cutting directly into potting soil. Keep the soil moist and mist the plant from time to time.​

Toxicity of Prayer Plants

The prayer plant is non-toxic to humans and animals. Prayer plants are not meant to be consumed, so do not allow curious pets or children to sample the leaves.

Varieties of Prayer Plants

There are many varieties of Maranta, but the most popular by far is the tricolor variation that pops up in garden centers. Alternatively, Maranta and Calathea plants are so closely associated with one another that its not uncommon for them to be mislabeled. Within the Maranta genus, a few species are seen more commonly:

  • M. tricolor: This is the most common prayer plant variety. It may be also be called the herringbone plant.
  • M. leuconeura kerchoveana: This is a variation with cream leaves and darker green splotches. It does not have red veins.
  • M. leuconeura massangeana: This variety has a darker leaf background with silvery leaf blotches along the midrib and white leaf veins. It is easily confused with the Calathea species.
