Insufficient Light (Etiolation)

Aglaonema are shade-tolerant but require moderate indirect light; when light levels are too low, the plant rapidly elongates its internodes to reach for a light source, resulting in weak, stretched stems.

Very Common

How to confirm: Observe if the new leaves are significantly smaller or further apart on the stem than older leaves.

1 Move your Aglaonema to a spot with brighter, indirect light to stop the stems from stretching further.

Overwatering and Root Suffocation

Excessive moisture in the substrate can lead to root decay, which prevents the plant from supporting structural integrity, causing stems to lose turgor pressure and appear limp or 'leggy'.

Common

How to confirm: Check the base of the stems for any signs of softening or dark, mushy discoloration.

1 Immediately reduce watering frequency and allow the top inch of soil to dry out completely before watering again to prevent further root rot.

2 Repot the plant in a well-draining, fresh potting mix and consider adding perlite to improve aeration and prevent future root suffocation.

3 Ensure the plant is in a pot with adequate drainage and use a saucer to catch excess water, making sure the plant is not sitting in stagnant water.

Improper Nutrient Regimen (Nitrogen Excess)

An overabundance of nitrogen-rich fertilizer can stimulate rapid, succulent vegetative growth that lacks the lignin strength needed to support the plant's weight.

Common

lightbulb

How to confirm: Review your fertilization schedule to see if high-nitrogen fertilizers were applied recently during a period of low light.

1 Flush the soil with water to leach out excess nitrogen salts from the root zone.

2 Switch to a more balanced fertilizer to support structural strength and reduce rapid, weak growth.
