Aglaonema Cecilia, or Chinese Evergreen ‘Cecilia’, is a popular houseplant known for its striking foliage and ease of care. This variety features wide, silvery-green leaves with dark green speckles, making it suitable for both novice and experienced plant enthusiasts.
Caring for Aglaonema Cecilia
Light Requirements
Aglaonema Cecilia thrives in bright, indirect light. An ideal spot is near a north or east-facing window, providing ample light without harsh direct sun. Direct sunlight, especially through glass, can scorch leaves. While it tolerates lower light, growth may slow and variegation lessen.
Watering Needs
Water thoroughly when the top inch or two of soil feels dry. Too much dryness causes wilting. Overwatering leads to root rot, so ensure drainage holes and discard excess water. Inconsistent watering, alternating between very dry and wet, also stresses the plant.
Humidity and Temperature
Aglaonema Cecilia prefers warm, consistent temperatures (65-75°F / 18-24°C). Below 60°F (15°C) is detrimental, as the plant is not cold-tolerant. Avoid cold drafts, air conditioning vents, or heaters to maintain a stable environment. Moderate to high humidity is beneficial; if dry, increase humidity through misting, a pebble tray, or a humidifier.
Soil Mix and Fertilization
A well-draining potting mix is suitable, such as a peat-based mix amended with perlite, vermiculite, or sand. A cactus/succulent blend also works well for drainage. During the active growing season (spring-summer), fertilize monthly with a balanced, half-strength water-soluble houseplant fertilizer. Fertilization is not needed in winter when growth slows.
Troubleshooting Common Aglaonema Cecilia Problems
Yellowing leaves often signal improper soil moisture, commonly from overwatering and root rot. Consistently wet soil deprives roots of oxygen, causing leaves to yellow and become mushy. Crispy, yellow leaves with dry soil indicate underwatering. Brown leaf tips often indicate low humidity or insufficient watering; increasing humidity can help.
Stunted growth can occur from nutrient deficiency or being root-bound. If roots circle the pot or grow from drainage holes, repotting is likely needed. Pests like spider mites, mealybugs, and scale insects can affect Aglaonema Cecilia. These sap-sucking insects cause yellowing and wilting. Regular inspection and prompt treatment with insecticidal soap or neem oil manage infestations.
Propagation and Repotting
Aglaonema Cecilia propagates via stem cuttings or division. For cuttings, take a healthy 4-6 inch segment with leaves and at least one node. Root cuttings in water (roots form in 3-4 weeks) or directly in moist, well-draining potting mix. Change water regularly to prevent algae.
Division is another effective method, often done during repotting. Gently separate offshoots or “daughter plants” from the main plant, ensuring each has its own roots and leaves. Plant these divisions into their own pots with fresh soil.
Repotting is generally needed every 2-3 years, or when the plant becomes root-bound. Signs include roots growing from drainage holes, stunted growth despite care, or soil drying quickly. Choose a pot one size larger for new growth. The best time is spring or summer, during active growth.
Is Aglaonema Cecilia Toxic
Aglaonema Cecilia, like other Chinese Evergreens, is toxic to humans and pets if ingested. It contains microscopic, needle-shaped calcium oxalate crystals. If consumed, these crystals cause irritation and a burning sensation in the mouth, throat, and digestive tract, leading to symptoms like swelling, redness, discomfort, excessive drooling, and vomiting. Keep Aglaonema Cecilia out of reach of children and pets.
