The parlor palm (Chamaedorea elegans) is one of the most popular houseplants, known for its elegant, feathery foliage and adaptability to indoor conditions. Originating from the rainforests of Southern Mexico and Guatemala, this plant is naturally an understory palm, which explains its tolerance for low light. While the parlor palm is a beautiful addition to any space, it is also a slow grower, typically taking years to reach its full indoor height of two to six feet. However, optimizing its environment and care can encourage a significantly faster growth rate compared to a neglected or stressed plant.
Optimizing Light and Placement
Light serves as the energy source for photosynthesis, directly correlating with the plant’s growth speed. Parlor palms can tolerate low light, but this environment will result in a much slower growth rate and potentially leggy, weaker fronds. To maximize growth, place the plant in a location that receives bright, filtered sunlight.
The ideal placement is near a north-facing or east-facing window where the light is gentle and diffused throughout the day. Direct, intense sun, particularly from a south or west-facing window, poses a risk of leaf scorch and should be avoided. If your home lacks natural indirect light, supplemental LED grow lights can provide the consistent energy needed to stimulate new growth.
Mastering Moisture and Humidity
Proper hydration is required for transporting nutrients and maintaining the turgor pressure necessary for cell expansion and new growth. Water thoroughly until it drains from the bottom of the pot. Allowing the top inch or two of the soil to dry out between waterings helps prevent the development of root rot, a common issue for this palm.
The parlor palm is native to humid tropical regions and thrives when ambient humidity levels are maintained between 50 and 60 percent. Dry air can cause the tips of the fronds to turn brown and crispy, signaling stress that inhibits growth. Practical steps to increase local humidity include placing the pot on a pebble tray filled with water or grouping several plants together to create a humid microclimate. Using a small room humidifier is the most effective way to ensure stable humidity levels, especially during winter months when indoor heating dries the air.
Providing the Right Nutritional Boost
Fertilization is the most direct way to accelerate the parlor palm’s growth by ensuring a steady supply of building blocks for new tissue. The palm requires a balanced fertilizer to support its foliage and root structure. A balanced NPK ratio, such as 8-8-8, 10-10-10, or a palm-specific fertilizer with a 3:1:3 ratio, is recommended for comprehensive nourishment.
Fertilize only during the active growing season, which generally spans from spring through summer. During the dormant winter months, when growth naturally slows, feeding should be stopped entirely. A highly effective strategy is to “feed lightly and often,” using a diluted liquid fertilizer every two to four weeks instead of applying a full-strength dose monthly.
This dilute, frequent feeding prevents the accumulation of salts that can lead to chemical burn on the sensitive roots while providing the consistent nitrogen needed for vegetative growth. The palm should be planted in a well-draining, peat-based potting mix, which supports healthy root function and efficient nutrient uptake.
Eliminating Physical Barriers to Growth
Two physical factors can halt the growth of a parlor palm: root constraint and pest infestations. Parlor palms tolerate being slightly root-bound, but if the roots are severely circling the pot, this restricts nutrient and water absorption. Signs that repotting is necessary include water running straight through the soil or roots pushing out of the drainage holes.
When repotting, select a container that is only one size larger than the current one, typically two to three inches wider in diameter. Moving to a much larger pot can cause the soil to remain wet for too long, potentially leading to fungal issues and root rot. Repotting should be done gently in the spring to minimize shock.
Common pests like spider mites and scale insects feed on the plant’s sap, draining its energy and resources, which stops new frond development. Spider mites manifest as fine webbing and speckling on the fronds, while scale appears as small, hard bumps. Regular inspection and prompt treatment with horticultural oils, such as neem oil, or insecticidal soap are necessary to remove these barriers and allow the plant to redirect energy back into growth.
