Why Is My Aglaonema Turning Yellow?

Aglaonema is a group of plants that are often used as indoor houseplants. They are easy to grow and care for, but there might be times when an aglaonema will turn yellow. If you’re looking at your plant and it’s not so green anymore, read this article to find out why the leaves have turned yellow!

Why Is My Aglaonema Turning Yellow? 

Aglaonema leaves turn yellow when they have been overwatered, been kept in the dark, or due to stress. However, the most common reason for aglaonema leaves turning yellow is overwatering.

Let’s explore these causes in more detail and what you can do about them.

Yellow Aglaonema Leaves from Overwatering

If you have a plant that is turning yellow, check the soil. If it appears soggy and water runs through your fingers when trying to dig in for a finger test, then your aglaonema has been overwatered.

When plants are over-watered they begin to suffocate because there is too much moisture around their roots preventing air from getting in. This lack of oxygen will cause leaves to turn yellow or brown at the tips and edges with some discoloration appearing on leaf undersides.

To fix overwatered aglaonema plants, you should stop watering, then let the plant dry out for a few days or weeks – depending on how much water you were giving it before.

If the plant also has root rot from the overwatering, you will need to repot it into a new container with potting soil. Then, you should treat the plant by removing all of its old soil and replacing it with a new potting mix – which will help prevent future problems from occurring again.

Yellow Aglaonema Leaves from Too Little Sunlight

The second reason your aglaonema is turning yellow could be because it isn’t getting enough light.

Your plant needs bright, indirect sunlight every day in order to survive and grow properly so its leaves can stay green. If you’re keeping your plant indoors, make sure that there are at least four hours of exposure to the sun during the day – but never directly under a window as this may burn the leaves, rather than giving them their needed dose of healthy light.

If you don’t have access to natural sunlight for an indoor houseplant like aglaonema, then artificial lighting ( Amazon link) is a good alternative. These lights work by emitting the same type of light your plant would be receiving during the day if it was outside.

Yellow Aglaonema Leaves from Stress

If your plant has recently been moved to a new location, or if you’ve started fertilizing it for the first time ever – then this could be why its leaves are turning yellow.

When plants get stressed out they lose their healthy green color and may turn various shades of brown or yellow instead.

You can reverse this process by making sure that your aglaonema gets back to being comfortable again. This means no more re-potting or major changes to its environment.

Yellow Aglaonema Leaves FAQs

Aglaonema plants aren’t the easiest plants to take care of. As such, you may find yourself with a few more questions about why some of your aglaonema leaves may be turning yellow.

Should I cut yellow leaves off the aglaonema plant?

Yellow leaves on a houseplant like an aglaonema can simply be cut off and thrown away. The leaves are already dead and not serving the plant anymore, so you don’t have to worry about doing something else with them.

Can I use a yellow leaf from my aglaonema as compost?

Yellow leaves from your houseplant can be used in compost piles if that is an option for you! You should tear or cut away any remaining stems or veins before adding them into your pile, though.

Is it normal for my aglaonema to lose some of its lower leaves?

It is normal for aglaonema plants to lose some of their lower leaves. They are not as strong and healthy as the rest, so they can turn yellow or brown quickly when exposed to too much light, lack of water, or poor soil drainage.

Will too little light cause my aglaonema leaves to turn yellow?

Yes, if your plant is not receiving any natural or artificial light for an extended period of time it will begin to turn yellow. You can fix this problem by moving the plant near a window so that it gets at least four hours of sunlight every day.

Will too much water cause my cat palm leaves to turn yellow?

Yes, if your plant is getting too much water for an extended period of time it will begin to turn yellow. You can fix this problem by allowing the soil to dry out a bit more before watering it again.

Will yellow aglaonema leaves turn green again?

No, it is very rare for yellow aglaonema leaves to turn green again.


In conclusion, there are a number of reasons why your aglaonema plant may be turning yellow. The most common cause is overwatering, which you can fix by letting the soil dry out and giving it less water in the future. However, if this doesn’t work or if root rot has set in – then there’s repotting to consider as well!

If your plant was moved recently, had an adjustment period with new fertilizer or lighting – then that could explain its current color too. Stress makes plants lose their healthy green shade when they become overwhelmed due to change.
