This is your ULTIMATE, complete care guide for Aglaonema or Chinese Evergreen!
In this post, you will find comprehensive care tips, solutions to frustrating problems you may be having, instructions on how to revive your plant, and an introduction to the huge array of the varieties out there that you will drool over!
Truly an amazing, versatile and easy to grow houseplant, Aglaonema is no longer the boring dark green plant that you see planted in shopping malls!
Although slow growing, Aglaonema, commonly known as Chinese Evergreen, tolerates poor light extremely well, comes in a staggering array of leaf colors, and is among the easiest houseplants you can grow!
Now let’s dive into how you can make your Chinese Evergreen or Aglaonema thrive!
CHINESE EVERGREEN CARE
This is an amazingly versatile plant when it comes to light conditions. Aglaonema species are native to humid and shady tropical forest habitats in Asia, so this gives you clues on care.
Fortunately for us, this is one of the best plants for low light inside the home. These plants are perfectly happy in front of a Northern exposure, or even Eastern exposure (morning sun) window.
Don’t let these plant sit in full sun though, and avoid any sun in the middle part of the day! A couple hours of morning sun or late afternoon sun is perfectly fine, and even beneficial.
Although it is preferable to have these plants right in front of a window, they are one of the few plants that will also do fine a few feet from a window.
If you think about the jungle floor where these grow, it can be pretty dim!
Aglaonema will even do pretty well in office settings that have no windows present, as long as there is fluorescent light on during the day. I used to have this plant in a windowless office and it did just fine!
And of course, if you have grow lights, they will thrive under these.
Be sure to turn your Aglaonema every week or two to encourage even growth and a more balanced plant.
If you keep them in the same orientation for too long, all the leave will bend towards the light (a phenomenon known as phototropism) and your plant will look unbalanced.
One word of advice though, if you have a highly variegated or particularly colorful variegated Aglaonema, such as a pink one in the photo below, these varieties will need a little more light than darker green ones in order to maintain their beautiful color.
If you keep these in conditions that are too dark, their colors will wash out and become “blah.”
Chinese evergreens are definitely freeze babies, so always avoid any cold rooms.
They will sit and sulk, and worse yet, if you keep your plant cold AND wet, you’ve set up prime conditions for root rot.
Ideal temperatures are 70-85F (21-29C). Try and avoid temperatures below 60F (16C), especially for long periods.
In addition, avoid areas in your home or office that have heating or cooling vents and keep away from any drafty windows and doors.
If you live in a climate that has cold winters, and you have rooms that are particularly cool during the winter, you may want to move your plant to a warmer room.
My “standard” blend that I use for most of my leafy tropicals works beautifully for Aglaonema.
This provides a nice, all-purpose mix for most tropical houseplants and works exceedingly well!
This section is critical so please read this carefully. Actually, all the advice on this page is important because having a beautiful specimen is all about consistency in care and having various aspects of care correct!
Always water your Aglaonema thoroughly. Make sure that you moisten all of the soil ,so circle that watering can all around the pot and keep watering until water comes out through the drainage holes.
Drainage holes are a must. Don’t let anyone tell you otherwise.
You should allow the top 1-2 inches of your plant’s soil to dry out before thinking about watering again.
I’ve included a section on problems near the end of this post, but this plant does not like to dry out completely. In fact, it hates it. Nor does it like to stay wet all the time, so you’ll have to strike a happy medium.
And please, for your own sanity and health of your plants, do not use moisture meters. They are junky and drive the wrong behavior.
I feel so strongly about this that I wrote a blog post explaining the 3 big dangers of using soil moisture meters.
For all my tropical foliage plants, I use an amazing fertilizer called Dyna-Gro Grow.
It is a premium, complete fertilizer that contains all the micro and macro nutrients that a plant needs to grow and thrive. With consistent use, alongside good growing conditions, you will see a big difference in your plants!
I highly recommend Dyna-Gro Grow and use it for the majority of my own houseplants.
In general, I like to fertilize most of my tropical foliage plants dilutely with every watering by adding 1/4 teaspoon per gallon of Dyna-Gro Grow during the active growing season.
For Aglaonema, which is a relatively slow growing plant in general, it is probably better to use my fertilization method described above for every other watering.
Don’t fertilize in the winter when your plant is not growing.
Aglaonema is native to very warm and humid areas in nature. High humidity indoors would benefit these plants, however they are very tolerant of average indoor humidity!
In my sunroom, where I keep the majority of my plants, I do run a humidifier during the months when we heat our home.
There are various ways to increase humidity for houseplants. Contrary to popular belief, misting does not increase humidity!
Read all about this topic, as well as my recommended humidifier, in my blog post on how to increase humidity for houseplants.
There are a few ways to propagate your plant.
The quickest way, if your plant has multiple stems growing out of the pot, is to simply take the plant out of the pot and carefully separate the rootball so that you have multiple plants to pot up.
If your plant has become leggy, you can cut off a stem to make a cutting, and root it either in soil or water.
SOIL PROPAGATION OF AGLAONEMA CUTTINGS
The simplest way to propagate is to insert your cuttings directly into a pot with soil. Simply make a cutting that has 2-3 inches of stem and insert into a 50/50 mix of soil and perlite. This make a great blend to root your cuttings.
Keep your cuttings in a bright area with no direct sun, and aim to keep your soil moist. Moist soil is important while you’re rooting cuttings.
And don’t worry about “overwatering” because all that perlite will keep the mix nice and fluffy and full of air so there will be no danger of root rot.
Maintaining higher humidity is beneficial as you’re propagating, but Aglaonema will root pretty easily regardless.
WATER PROPAGATION OF AGLAONEMA CUTTINGS
Many people struggle with transferring cuttings into soil that have been previously rooted in water, but if you follow my care tips in this post, you should not have a big problem.
I rooted the cutting of my Aglaonema ‘Cutlass’ below in water:
Once the roots were about an inch long or so, I transferred it into a pot. Two years after the cutting was taken, here is what the plant looks like now.
As you can see, growth is pretty slow, but it has grown two additional stems from the soil.
Don’t be shocked or discouraged if one of the lower leaves yellows while your’e propagating. Your plant will recover.
One of the reasons I love this genus of plants so much is that there are SO many varieties, including many different colored Aglaonema with striking variegation!
Take a look at just some of the amazing, colorful Aglaonema varieties out there. Remember that the really colorful ones tend to need a little bit more light than the plainer green ones in order to maintain their vibrant color.
Aglaonema ‘Lady Valentine’
A stunning pink Chinese evergreen! Who wouldn’t love to get their hands on this one?
The pink leaves with green speckles are stunning!
Aglaonema ‘Siam Aurora’
Heavily edged with pink, the veins are also pink. The combination of green and pink on the large leaves is quite striking.
Aglaonema ‘Sparkling Sarah’
The beautiful pink midrib on the leaves and splashes of pink variegation is just lovely.
Algaonema ‘pictum tricolor’
This one is the holy grail of Aglaonemas. It is hard to find, very expensive when you do find it, and trickier to care for than other Aglaonemas. Be sure to cut the flowers off on this one if they do appear in order to keep the foliage in the best shape.
Aglaonema ‘Silver Queen’
This one is a pretty common and popular variety. The leaves are beautifully marbled and this is an especially easy-care Aglaonema.
Aglaonema ‘Maria Christina’
Similar to ‘Silver Queen’ but with different shades of green and less silver on the leaves, this one is equally as easy to care for and commonly available.
I love this variety for the narrower leaves that makes it so distinct.
Aglaonema ‘Snow White’
Lots of white variegation on these leaves. So much so that it reminds me of Dieffenbachia!
CURLING, LIMP, OR DROOPY LEAVES
So many plant woes are caused by extremes in soil moisture, and this is another example.
If your leaves are curling and start to appear droopy, check your soil. In most cases, your soil has probably gone completely dry. We’ve all done this!
If your soil has gone really bone dry, you may have to work at it a little in order for your soil to accept moisture again.
Have you ever watered a plant that has gone super dry and when you try and water, the water just goes straight through very quickly and doesn’t seem to absorb into the soil?
To fix this, you can just continually run water several times through the pot until your soil has accepted more water. You can often tell the difference by picking up the pot. It will feel much heavier once the soil is saturated.
Or you can let your plant sit in a container of warm water (don’t use cold), and allow the plant to absorb water from the bottom. You can use a bucket, a bathtub, a plastic tray, etc. Just make sure you have at least 2-3 inches of water and give it a good hour or so before you discard excess water.
YELLOWING LOWER LEAVES
Is it normal for an old leaf to turn yellow eventually? Absolutely.
But you should always check your soil moisture as soon as you see any yellow leaves. Especially if multiple yellow leaves seem to appear very quickly on your plant.
More often than not, yellowing leaves are caused by improper soil moisture (either too dry or too wet).
I know when I’ve ignored my plant and let it get super dry, the lower leaves will quickly yellow. Do this repeatedly, and you will have a leggy plant.
To prevent yellowing leaves, you need a balance in soil moisture. Never allow your soil to get completely dry (especially for extended periods) and never let your plant stay wet for extended periods.
Aglaonemas don’t like wet feet either, so make sure to discard any excess water after it drains out of the pot (and always have a drainage hole!). Your plant will quickly get root rot if it sits in water or soil that is continually wet.
The key to preventing yellowing leaves is to aim to have the top inch or two of soil dry out before watering again. This is the main key to avoiding yellow leaves.
CONSISTENCY is very important in plant care!
There are other reasons why leaves can turn yellow. Read my blog post dedicated to why your houseplant leaves are yellowing and what you can do to fix it.
BROWN, CRISPY LEAF TIPS
If your Chinese Evergreen has brown, crispy leaf tips, it is most likely due to your soil being too dry. Feel the soil to be sure.
If it is dry, give it a good watering. Although your brown tips won’t turn green again, with consistently good watering, all your future leaves should look good.

SHOULD YOU CUT OFF THE FLOWER?
There is much controversy on this topic, but I will give you my thoughts. Take a look at a flower which is almost done on my Aglaonema ‘Cutlass’ and a new bud that is about to open soon.
The bottom line is that no one grows Aglaonema for their flowers! I cut these buds off right after I took the photo.
I would recommend cutting the flower buds off as soon as you can clearly see that they’re flower buds and not leaves. The thought is that the plant can then focus on growing the foliage that we want, instead of directing energy to the flowers, which aren’t too terribly interesting to look at anyway.
Does it really matter that much? In many Aglaonemas it probably won’t make a gigantic difference, with one potential notable exception.
I haven’t grown Aglaonema pictum ‘Tricolor’ but I have heard from many people that their plants suffered a quick demise after it bloomed, so you may want to cut that one off for sure if you have this particular plant (if you can even find it in stock anywhere, that is!)
FIXING A LEGGY AGLAONEMA
Over time, as a result of inconsistent care, especially if you’ve let your plant dry out and the lower leaves have yellowed, your plant can become leggy.
Fortunately you can fix this by cutting off the leggy part, rooting it in water, and then planting it in soil. See the propagation section in this blog post for details.
DEALING WITH PESTS
We all deal with pests in houseplants. It is inevitable! If your houseplant care has not been consistent and your plant has become stressed (from drought, cold, etc.), your plant will be more prone to pests.
Some of the most common pests you might encounter on your Aglaonema are spider mites, mealy bugs, and scale.
Check out my blog post on dealing with spider mites naturally without harsh chemicals. I’m working on additional posts for other pests that will be published at some point.
IS AGLAONEMA TOXIC?
Chinese evergreen is toxic to dogs and cats according to the American Society for the Prevention of Cruelty to Animals (ASPCA) because it contains a compound called calcium oxalate.
If you cat or dog has ingested Aglaonema, they may experience pain, irritation and swelling in the mouth, tongue and lips, and even vomiting and difficulty swallowing.
