Wondering why are my chinese evergreen plant leaves turning yellow? Let’s diagnose this common problem and get your plant healthy again!
Chinese evergreen plants (Aglaonema) are a super popular houseplant. These plants grow low and wide and have beautiful variegated green leaves.
They are super easy to keep happy and propagate easily too.
So, if your chinese evergreen plant isn’t doing well, you might be a little puzzled.
Kind of like how snake plant was one of my first plants – it had a tag on it that said IRON PLANT HARD TO KILL – and I killed it within the month.
Even easy plants can have problems and need some troubleshooting.
So, today we are going to chat about yellowing leaves on a chinese evergreen plant and what to do about them!
Why is my Chinese Evergreen plant turning yellow?
Here are a few common reasons that you might get chinese evergreen plant yellowing leaves.
- Low humidity
- Inconsistant watering
- Insufficient light
- Root bound plant
- Bacterial Leaf Spot
- Old age
Overwatering is the #1 cause of yellowing leaves on most indoor house plants. In general, plants don’t like to sit in excess water. Pooling water can lead to root rot which will kill your plant.
If you suspect overwatering, stick your finger about 2 inches into the soil. Does it feel wet? Don’t water again until it dries out.
If your plant is way over watered, take it out of the pot. Dump out any excess water and wet soil and re-pot with fresh potting mix.
Be sure that your pot has drainage holes to prevent excess water from pooling in the future.
I find this to be MUCH less frequent than over watering, but low humidity can cause leaf drop. Usually the leaves will get brown, crispy spots on them (often on the tips). Then, the leaves might turn yellow.
These symptoms indicate that the plant is drying out. If it’s being watered well, misting the leaves can help to improve humidity in the air.
In my experience, chinese evergreen plants are NOT very picky. However, some claim that they like to be on a watering schedule.
For example, I water my plants every Sunday. There is a big asterisk there – if the pot still feels damp from last week, I don’t water again.
My husband used to keep plants in his cubicle and he watered them just a teeny splash five days a week.
Both plants were happy. But maybe they were like a toddler, just happy to be on a schedule.
Going from bone dry to soaking wet at random intervals could stress out your plant and lead to yellowing leaves.
If in doubt, establish a regular watering schedule and try to stick to it.
If your plant isn’t getting enough light, the leaves will start to turn yellow and drop. This will especially happen to older leaves towards the base of the plant.
The cure to this is to move your plant into brighter light. These plants can live in medium-low level light, but they still need some light to thrive.
Root Bound Plant
It is possible that your plant has become root bound. Basically, the roots are too big for the pot.
Pull it out of the pot and see! If it’s been there a while – this is a real possibility.
If the roots are tightly packed or even poking out the drainage hole – time for a bigger pot. Add fresh potting soil while you are at it for a happier plant!
Bacterial Leaf Spot
Soft, brown, mushy spots on a leaf are called Bacterial Leaf Spots. This come from water sitting on the leaves and rotting them.
Remove all effected leaves and avoid getting the leaves wet when you water it!
Spider mites, scale, and mealy bugs can get on the underside of leaves and suck the nutrients out of your plant.
If you suspect pests, isolate your plant to help prevent it from spreading to other plants.
As plants get older, it is natural for some of the older leaves to yellow and fall off, making room for new growth. Keeping a leaf green takes energy, and some plants decide to allocate that energy to new plants.
If this is the case, you will have yellowing of older leaves – near the base of the plant – only, and not new growth.
