Potted palm trees add a tropical style to an indoor space while filtering out indoor air pollutants. Indoor palm trees can also establish traffic patterns in a room, add decoration to a sterile area, and reduce noise by absorbing sound. Only certain varieties of palm trees grow well indoors, such as the parlor palm, reed palm, lady palm and areca palm. In order for palm trees to increase in height, they must be cared for properly.
Plant the baby palm tree in a clay pot with well-draining potting mix. The pot should have functioning drain holes, with a saucer beneath it to catch water drips.
Place reed palms and parlor palms at least 6 feet from windows, in indirect sunlight. Areca palms and lady palms require brightly lit areas and should be placed within 3 feet of south-, west- or east-facing windows. Potted palm trees require proper amounts of sunlight in order to grow properly.
Water the palm tree thoroughly, as soon as the soil becomes dry under the surface. You know you have watered enough when water seeps out of the bottom of the pot, onto the saucer. Water the tree less in winter, to prevent damaging the root system.
Keep the indoor palm tree away from air vents, as blasts of cool or warm air can stunt its growth. The humidity level in the room should be kept at 40 to 60 percent to prevent the plant from losing water through its leaves. If you have trouble maintaining an adequate humidity level in the room, place a humidifier near the plant.
Fertilize the actively growing palm tree three to four times per year with controlled-release fertilizer. Follow the manufacturer's directions when fertilizing. Fertilizing should be reduced in winter, and a complete palm fertilizer formulated for potted plants can be used according to the manufacturer's instructions.
Repotting Palm Trees
Prepare to repot the palm tree once the root system completely fills the container. Water the plant for several hours. Slow-growing palm trees should be repotted every two to three years, while fast-growing palms should be repotted yearly.
Find a pot with a diameter measuring half the height of the palm tree. Fill the pot with potting mix, then press the mix down with your hands.
Invert the old pot to remove the palm tree and root system. Plant the palm tree with the root system in the new pot.
Pour more potting mix around the root ball, and then press the mix down firmly. Water the palm tree thoroughly until water seeps out from under the pot.
Continue to care for the potted palm tree as you always have. Keep transplanting the palm tree as it grows taller.
