The majesty palm tree (Ravenea spp.) is a fast-growing, small- to medium-sized palm tree that's native to Madagascar. Majesty palms can grow 20 to 40 feet tall with massive, feathery fronds that grow from a smooth, flared trunk. Majesty palms are frost-tender and cannot tolerate temperatures below 30 degrees, so it's suitable for growing in the ground outdoors only in USDA hardiness zones 9 through 11. The majesty palm tree can also grow in containers indoors.
Water your majesty palm tree deeply and thoroughly during the summer when conditions are dry. You should water the palm when the soil feels dry to the touch or at least once per week in the absence of rainfall.
Feed your majesty palm once every three months from April through September with a 12-4-12-4 NPKMg (Nitrogen-Phosphorous-Potassium-Magnesium) palm tree fertilizer. Spread the fertilizer on the ground over the entire canopy area of the palm tree, keeping the fertilizer away from the trunk.
Spread a 3-inch-thick layer of mulch on the ground around the majesty palm tree to control weeds and grasses, as well as to retain soil moisture. Keep the mulch 2 to 3 inches away from the trunk.
Support your newly planted majesty palm tree for the first six to eight months, especially if you live in a hurricane-vulnerable area. Brace the palm by positioning three equally spaced 2-by-4 boards that are each 1 foot long vertically on the trunk, secured with two nylon straps. Place thick, folded layers of burlap between the boards and the trunk to protect the trunk from damage.
Lean longer 2-by-4 boards against the trunk onto the short boards at a 45-degree angle. Nail or screw the ends of the long boards into the short boards that are against the trunk. Don't nail or screw into the trunk.
