Everything it needs
9 essentials at a glance
Watering
Aglaonema Commutatum prefers to be watered when the top inch of soil feels dry.
In general, water every 1-2 weeks, adjusting frequency based on humidity and temperature. During the growing season (spring and summer), increase watering slightly, while in fall and winter, reduce it. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf curling and browning tips.
Light
This plant thrives in low to moderate indirect light but can tolerate bright, indirect light.
Avoid direct sunlight as it can scorch the leaves. Ideally, place it near a north or east-facing window, where it can receive 6-8 hours of filtered light daily. It can adapt to lower light conditions but may grow more slowly.
Soil
Aglaonema prefers a well-draining potting mix with a pH range of 6.0 to 6.5.
A mix of peat, perlite, and pine bark is ideal for good aeration and drainage. Ensure the pot has drainage holes to prevent water retention, which can lead to root rot.
Humidity
This plant enjoys high humidity levels, ideally between 50-70%.
To increase humidity, consider using a humidifier, placing a tray of water near the plant, or misting the leaves regularly. Signs of low humidity include browning leaf tips and edges.
Temperature
Aglaonema thrives in temperatures between 65-80°F (18-27°C) and is hardy in USDA zones 10-12.
It is sensitive to cold and should be protected from temperatures below 50°F (10°C). During winter, ensure it is kept away from drafts and heating vents.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or similar, diluted to half strength.
Fertilize every 4-6 weeks during the growing season and reduce to once every 2-3 months in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Aglaonema as needed to remove yellow or damaged leaves, ideally in spring.
Use clean, sharp scissors or pruning shears to make clean cuts at the base of the stem. Deadheading is not necessary, but removing spent leaves can promote a healthier appearance.
Repotting
Repot Aglaonema every 1-2 years or when it becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter than the current one. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix, ensuring the root ball is at the same depth as before.
Propagation
Aglaonema can be propagated through stem cuttings or division.
For stem cuttings, take a cutting with at least one node, place it in water or moist soil, and keep it warm and humid until roots develop. For division, carefully separate the plant into sections during repotting, ensuring each section has roots and leaves. The best time for propagation is in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.
How to fix it
Check soil moisture and adjust watering frequency. Move the plant to a brighter location if it is in low light.
Browning leaf tips
Why it happens
Low humidity or under-watering.
How to fix it
Increase humidity levels around the plant and ensure consistent watering.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location to encourage more compact growth.
Root rot
Why it happens
Over-watering or poor drainage.
How to fix it
Allow the soil to dry out before watering again and ensure the pot has adequate drainage.
Pests (e.g., spider mites, aphids)
Why it happens
Dry conditions or stress.
How to fix it
Inspect the plant regularly, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives adequate light and humidity. Monitor for pests and increase watering as needed.
Fall
In fall, gradually reduce watering as growth slows down. Continue to fertilize until late fall, then cut back during the winter months.
Winter
In winter, keep the plant in a warm location away from drafts. Reduce watering and stop fertilizing until spring.
Toxicity & Safety
Aglaonema is considered mildly toxic to pets and humans. Ingestion of the leaves can cause irritation, vomiting, and difficulty swallowing. Keep it out of reach of children and pets.
