Majestic palm plants (Ravenea rivularis) are slow-growing palms that can reach up to 40 feet tall in the wild, according to information published by the University of Oklahoma. Also sometimes called "majesty palms", these tropical beauties are native to Madagascar. Although they are sometimes marketed as houseplants, these palms develop a large, thick trunk over time, making them difficult to grow indoors.
Plant your palm outdoors in the ground only if you live in United States Department of Agriculture (USDA) growing zones 9 through 11. These climates have the warmth and humidity required for the majestic palm to grow correctly, according to information published by the University of Oklahoma. Otherwise, grow your palm in a container and bring it indoors when cool weather threatens.
Place or plant your majestic palm in a location where it will receive either full sunlight or a small amount of light or dappled shade. These plants need a lot of light in order to thrive.
Use a potting medium that contains large amounts of peat moss and sand or perlite to help drain the water. Or, amend your garden soil with these ingredients.
Keep the soil consistently moist. These plants need moist, but not soggy, soil for optimum growth, according to the University of Oklahoma. Water when the plant begins to dry out, but do not over-water. Too much water, and the plant may develop root rot, a fungal disease. For that reason, do not plant this palm in locations that are prone to flooding.
Fertilize once a month with a balanced (10-10-10 or 20-20-20) fertilizer that includes micro-nutrients, especially iron. If you do not feed this plant on a regular basis, the deep green color of the graceful fronds will fade, according to information published by Floridata.
