The Aglaonema ‘Moonstone’, or Chinese Evergreen, is a popular houseplant known for its striking foliage. Its large, lance-shaped leaves display a vibrant mix of colors, typically featuring light green or silvery bases accented with darker green edges and speckles of pink or red. Native to the humid regions of Asia and New Guinea, this tropical plant’s lush appearance and adaptability make it a favored indoor choice.
Aglaonema Moonstone Care
Light Needs
Aglaonema ‘Moonstone’ thrives in bright, indirect light. Placing it near an east or north-facing window that receives filtered sunlight is ideal. Direct sunlight can scorch its delicate leaves, causing brown spots or fading colors. Conversely, insufficient light leads to leggy growth, smaller leaves, and reduced variegation intensity. If the plant appears to be stretching or its colors are dulling, adjust its position to a brighter, yet still indirect, location.
Watering Practices
Proper watering is important for Aglaonema ‘Moonstone’ health. The soil should dry out partially between waterings, typically when the top inch or two feels dry to the touch. When watering, thoroughly drench the soil until water drains from the bottom of the pot, ensuring the entire root ball receives moisture. Avoiding overwatering is important, as soggy soil can lead to root rot, manifesting as yellowing leaves and a mushy stem. Underwatering, indicated by drooping leaves or dry, crispy leaf edges, means the plant needs water more frequently.
Soil Requirements
A well-draining potting mix is important for Aglaonema ‘Moonstone’ to prevent waterlogged roots. A suitable mix includes peat moss, perlite, and vermiculite, providing both moisture retention and aeration. The soil pH should be slightly acidic to neutral for optimal nutrient uptake. Good drainage prevents excess water accumulation, which can suffocate roots and promote fungal diseases.
Temperature and Humidity
As a tropical plant, Aglaonema ‘Moonstone’ prefers warm, consistent temperatures, between 65°F and 80°F (18°C and 27°C). It is sensitive to cold drafts and sudden temperature fluctuations, which can stress the plant and cause leaf damage. Maintaining higher humidity levels benefits this plant. Increase humidity by placing it on a pebble tray filled with water, grouping it with other plants, or using a room humidifier.
Fertilizing
During the active growing season, spanning spring and summer, Aglaonema ‘Moonstone’ benefits from regular fertilization. A balanced liquid fertilizer, diluted to half strength, can be applied every four to six weeks. Reduce or cease fertilization during fall and winter months when the plant’s growth naturally slows. Signs of nutrient deficiency include stunted growth or pale, yellowing leaves, while over-fertilization can lead to fertilizer burn, characterized by crispy leaf edges and root damage.
Repotting and Propagating
Aglaonema ‘Moonstone’ requires repotting every two to three years, or when root-bound, indicated by roots growing out of drainage holes or circling tightly within the pot. Choose a new pot only one to two inches larger in diameter than the current one to avoid overwatering issues. When repotting, gently remove the plant, loosen any circling roots, and place it in the new pot with fresh, well-draining soil.
Propagation of Aglaonema ‘Moonstone’ is achieved through stem cuttings. Select a healthy stem with several leaves and at least one node. Cut the stem just below a node using a clean, sharp tool. The cutting can then be rooted in water, where roots typically emerge within a few weeks, or directly in a moist, well-draining potting mix. For soil propagation, ensure the cutting is kept in a warm, humid environment until new growth appears, signaling successful rooting.
Troubleshooting Common Issues
Yellowing leaves on an Aglaonema ‘Moonstone’ can indicate several issues, including overwatering (if soil is soggy) or underwatering (if leaves are drooping and crispy). Browning leaf tips point to low humidity or an accumulation of salts from tap water or excessive fertilizer. Increasing humidity and flushing the soil with distilled or filtered water can help alleviate this.
Stunted growth suggests a lack of nutrients, requiring regular fertilization during the growing season. It can also indicate the plant is root-bound and needs repotting into a slightly larger container. Pest infestations, such as spider mites, mealybugs, or scale, can also hinder growth and cause leaf discoloration. Inspect the plant regularly for small insects or sticky residue, and treat affected areas with insecticidal soap or neem oil for effective pest control.
