Everything it needs
9 essentials at a glance
Watering
Aglaonema rotundum prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf droop and browning tips.
Light
This plant thrives in low to medium indirect light but can tolerate brighter conditions as well.
Ideally, place it near a window with filtered light or in a bright room away from direct sunlight. It can handle 4-6 hours of light daily but avoid harsh afternoon sun to prevent leaf scorch.
Soil
Aglaonema rotundum prefers a well-draining potting mix that retains some moisture.
A mix of peat, perlite, and orchid bark works well, with a pH range of 5.5 to 6.5. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This plant enjoys high humidity levels, ideally between 50-70%.
To increase humidity, consider using a humidifier, placing a tray of water with pebbles under the pot, or misting the leaves regularly. Signs of low humidity include browning leaf edges and leaf drop.
Temperature
Aglaonema rotundum thrives in temperatures between 65-80°F (18-27°C) and is hardy in USDA zones 10-12.
It can tolerate occasional dips to 60°F (15°C) but should be protected from frost and extreme heat.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor leaf coloration.
Pruning
Prune Aglaonema rotundum in spring to remove any dead or yellowing leaves and to shape the plant.
Use clean, sharp scissors or pruning shears to avoid damaging the plant. Regularly check for any leggy growth and trim back as needed to encourage bushier growth.
Repotting
Repot 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, carefully remove the plant from its old pot, and place it in fresh soil, ensuring the root ball is level with the new soil surface.
Propagation
Propagation can be done through division or stem cuttings.
For division, carefully separate a healthy section of the plant with roots during repotting. For stem cuttings, take a 4-6 inch cutting with a few leaves, allow it to callous for a few hours, and then place it in water or moist soil. Best timing is during spring or early summer.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks and consider repotting if needed.
Summer
During summer, maintain consistent moisture and humidity levels. Ensure the plant is not exposed to direct sunlight, which can scorch the leaves.
Fall
In fall, gradually reduce watering as growth slows. Continue fertilizing every 2-3 months and monitor for pests as indoor conditions change.
Winter
In winter, reduce watering to every 2-3 weeks and avoid fertilizing. Keep the plant in a warm location away from drafts and cold windows.
Toxicity & Safety
Aglaonema rotundum is mildly toxic to pets and humans if ingested. The leaves contain calcium oxalate crystals, which can cause irritation, swelling, and digestive discomfort. Symptoms of ingestion include mouth and throat irritation, nausea, and vomiting.
