At a glance
- No new leaves in a dim location: Low light; move to moderate or bright indirect light (more for colored varieties)
- Colored variety losing color and not growing: Insufficient light; brightly colored aglaonema need bright indirect light
- Stopped with yellowing leaves and wet soil: Overwatering; let dry and check roots
- Stopped in autumn or winter: Seasonal slowdown; normal, resume fertilizing in spring
- Stopped in a cold room or near a drafty window: Temperature stress; keep above 65°F
- Stopped after years in the same pot: Root-bound or depleted soil; repot in spring
How fast aglaonema normally grows
Aglaonema (Chinese evergreen) is a slow to moderate grower with one of the best reputations for tolerating neglect of any houseplant. In good conditions during spring and summer, most varieties produce a new leaf every 3 to 5 weeks. Growth slows in autumn and may pause in winter. The green-leaved varieties are among the most shade-tolerant houseplants available and can grow new leaves in quite dim conditions, though more slowly than in better light. The brightly colored varieties (red, pink, orange, yellow, and silver-patterned types) need bright indirect light to grow actively and maintain their vivid coloration; in low light they revert toward greener growth and slow considerably. Understanding which variety you have significantly affects what light level the plant actually needs.
Cause 1: Low light
Signs: No new leaves during the growing season. The plant is in a dim position or far from windows. For colored varieties: the coloration has faded or new leaves are much less vivid than older ones. Growth was better before the plant was moved to its current location. For green varieties in genuinely very dark rooms: the plant has been static for many months.
Why it happens: Aglaonema's famous tolerance for low light is real but has limits. Green varieties survive in dim conditions and can still produce new leaves slowly. Colored varieties need more light to produce their vivid pigmentation and to grow actively. In dim conditions, all aglaonema varieties slow down; colored varieties also lose their distinctive appearance as they produce more green chlorophyll to compensate for insufficient light.
Fix: For green varieties, move to moderate indirect light — a few feet from a window with good natural light. For colored varieties, move to bright indirect light, within 2 to 3 feet of a bright window. Avoid direct sun, which scorches the leaves of all aglaonema varieties. New growth should appear within 3 to 5 weeks during the growing season after improving the light.
Cause 2: Overwatering and root rot
Signs: Growth has stopped and some leaves are yellowing, particularly older ones. The soil has been consistently wet or moist. The pot feels heavy between waterings. The plant looks generally unwell or dull. Roots, when inspected, are brown or black and mushy rather than white and firm.
Why it happens: Aglaonema prefers to dry out moderately between waterings. Consistently wet soil destroys the root system through rot, eliminating the plant's ability to take up nutrients and water. Root rot in aglaonema often develops gradually and is well established before the plant shows obvious symptoms, because aglaonema is so durable it can look acceptable for weeks while its root system deteriorates.
Fix: Allow the soil to dry out between waterings — check the top 1 to 2 inches and water only when that layer is dry. If root rot is suspected, remove from the pot, trim all dark mushy roots to firm tissue, and repot in fresh, well-draining mix. Recovery takes 4 to 6 weeks. Going forward, reduce watering frequency and adjust based on the season and light level: plants in low light or cool rooms need far less frequent watering than plants in bright warm positions.
Cause 3: Seasonal dormancy
Signs: Growth slowed or stopped in autumn or winter. The plant looks healthy. The care routine has not changed. New leaves were appearing regularly earlier in the year.
Why it happens: Aglaonema reduces its growth rate in winter in response to lower light intensity and shorter days. Because aglaonema is already a slow grower, even a slight seasonal reduction can make it appear completely static for months.
Fix: No action needed for a healthy plant in winter. Reduce fertilizing or stop entirely until spring. Reduce watering frequency since the plant's water needs are lower when it is not actively growing. Resume a monthly fertilizing schedule when new growth appears in spring.
Cause 4: Cold temperatures
Signs: Growth stopped or slowed during cool weather. The plant is near a cold window, exterior wall, or air conditioning vent. Temperatures regularly drop below 60 to 65 degrees Fahrenheit. Some leaves may have developed brown patches or drops from cold damage.
Why it happens: Aglaonema is a tropical plant from Southeast Asian forests and is particularly sensitive to cold, more so than many other houseplants. Below 60 degrees Fahrenheit, growth stops. Below 55 degrees, the plant starts to suffer cold damage. Air conditioning is a common summer culprit: a well-lit aglaonema near an air conditioning vent can stop growing in the middle of the growing season because the cold dry air is suppressing its root function.
Fix: Move to a consistently warm location, above 65 degrees Fahrenheit, away from cold windows, exterior walls, and vents. Growth should resume within 2 to 4 weeks of consistently warm conditions during the growing season.
Cause 5: Nutrient deficiency or root binding
Signs: The plant has been in the same soil for more than 1 to 2 years without fertilizing. Growth is slow despite adequate light and correct watering. New leaves are smaller than established ones. Roots may be circling or emerging from drainage holes.
Why it happens: Potting soil nutrients deplete within 6 to 12 months. Aglaonema is not a heavy feeder but does benefit from occasional fertilizing once the initial soil nutrients are exhausted. A severely root-bound plant also cannot take up water and nutrients as efficiently.
Fix: Begin monthly fertilizing from spring through summer with a balanced liquid fertilizer at half strength. If the plant is root-bound, repot in spring into a container 1 to 2 inches wider using fresh potting mix. New growth should increase in size and frequency within 3 to 4 weeks of fertilizing in good light.
