Aglaonema nitidum
Aglaonema nitidum
Aglaonema nitidum, commonly known as the Chinese evergreen, is a stunning houseplant prized for its lush foliage and adaptability. Native to tropical regions, it thrives in low light and is perfect for beginners looking to add greenery to their indoor spaces.
Everything it needs
9 essentials at a glance
Watering
Aglaonema nitidum prefers to be watered when the top inch of soil feels dry to the touch.
Typically, this means watering every 1-2 weeks, allowing excess water to drain out. During the growing season (spring and summer), increase frequency slightly, but reduce in the fall and winter. 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 medium indirect light but can tolerate bright, filtered light.
Ideal placement is near a window with sheer curtains or in a well-lit room. It can handle 4-6 hours of indirect sunlight daily, but prolonged exposure to direct sunlight can scorch the leaves.
Soil
Aglaonema nitidum prefers a well-draining potting mix with a pH range of 6.0 to 6.5.
A mix of peat, perlite, and orchid bark is ideal for drainage and aeration. Ensure the pot has drainage holes to prevent water accumulation, which can lead to root rot.
Humidity
This plant enjoys high humidity levels of around 50-60%.
To increase humidity, consider using a humidifier, placing a pebble tray with water beneath the pot, or grouping it with other plants. Signs of low humidity stress include browning leaf edges and drooping leaves.
Temperature
Aglaonema nitidum prefers temperatures between 65-80°F (18-27°C) and is hardy in zones 10-12.
It is sensitive to cold drafts and should be kept away from temperatures below 50°F (10°C). During winter, ensure it is not exposed to cold windows.
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 or stop in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Aglaonema nitidum as needed to remove yellow or damaged leaves, which can be done at any time of year.
Use clean, sharp scissors or pruning shears to make clean cuts. Regular pruning helps maintain shape and encourages bushier growth.
Repotting
Repot Aglaonema nitidum every 1-2 years or when the roots outgrow the pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter, and gently loosen the root ball before placing it in fresh soil.
Propagation
Propagation can be done through stem cuttings or division.
For stem cuttings, take a 4-6 inch 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 root ball during repotting, ensuring each division has roots and leaves. The best time for propagation is in spring.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow actively. Fertilize every 4-6 weeks with a balanced fertilizer to promote healthy growth.
Summer
During summer, ensure the plant receives adequate indirect light and maintain humidity levels. Water more frequently as the soil dries out faster in warmer temperatures.
Fall
In fall, gradually reduce watering as the plant's growth slows down. Monitor for pests and adjust humidity levels as indoor air becomes drier.
Winter
In winter, keep the plant in a warm location away from cold drafts. Water less frequently and avoid fertilizing until spring, as the plant enters dormancy.
Toxicity & Safety
Aglaonema nitidum is mildly toxic to pets and humans if ingested. Symptoms may include oral irritation, swelling, and difficulty swallowing. The leaves and stems are the most toxic parts.
