The Philippine Evergreen (Aglaonema) is a popular indoor plant known for its vibrant, decorative foliage. Hailing from the tropical and subtropical rainforests of Southeast Asia, this plant has adapted to the shaded understory, making it an excellent choice for indoor cultivation. Its striking appearance, which includes patterns of silver, pink, and red across its leaves, makes it a resilient and beautiful houseplant for growers of all experience levels.
Ideal Lighting and Temperature
The Aglaonema thrives in bright, filtered light. While the plant tolerates lower light, this slows growth and may cause the loss of vibrant coloration and variegation. To maintain striking patterns, medium to bright indirect exposure is required. Avoid direct afternoon sun, as intense radiation can easily scorch the leaves.
As a tropical species, the Philippine Evergreen requires consistently warm temperatures. The ideal range is 65°F to 80°F. Temperatures below 60°F cause significant stress, leading to potential leaf damage and stunted growth. Protect the plant from sudden temperature fluctuations, such as drafts or cold air conditioning vents.
Watering and Soil Requirements
Watering the Philippine Evergreen requires allowing the upper layer of the substrate to partially dry between applications. Check the soil moisture and water thoroughly only when the top one to two inches of the potting mix feel dry to the touch. This prevents the roots from sitting in saturated soil, which is the primary cause of root rot and subsequent plant decline. When watering, allow the liquid to flow freely out of the drainage holes before discarding any collected excess water from the saucer.
A quality, peat-based potting mix amended with materials like perlite or orchid bark provides the necessary aeration while preventing compaction. While the plant tolerates average household humidity, it benefits significantly from higher levels. Increased humidity can be achieved by placing the pot on a pebble tray filled with water or by using a dedicated humidifier.
Essential Maintenance Tasks
Provide periodic nutritional support during the active growth period. During spring and summer, apply a balanced liquid houseplant fertilizer diluted to half the recommended strength once a month. Suspend feeding entirely during the winter months when the plant’s growth naturally slows.
Remove any foliage that has turned yellow or brown, as this redirects the plant’s energy toward new, healthy growth. The leaves should also be wiped gently with a damp cloth every few weeks to remove accumulated dust. Dust buildup can impede the leaf’s ability to photosynthesize. Repotting is necessary only every two to three years, or when the plant becomes visibly root-bound. The new container should only be one size larger than the previous one to avoid excess soil volume.
Identifying and Addressing Common Issues
The Philippine Evergreen can occasionally develop issues that require intervention. Yellowing leaves, particularly on the lower stem, often signal overwatering or poor drainage, requiring an adjustment to the watering schedule or inspection of drainage holes. Conversely, brown tips or edges on the leaves indicate low atmospheric humidity or a buildup of mineral salts from tap water.
Regularly inspect the undersides of the leaves and stem junctions for common houseplant pests such as spider mites and mealybugs. If an infestation is detected, use a mild application of insecticidal soap or neem oil. Note that Aglaonema contains insoluble calcium oxalate crystals, making all parts of the plant toxic if ingested; place the plant out of reach of pets and small children.
