Why Is My Aglaonema Harlequin Dying?

Why Is My Aglaonema Harlequin Dying?

If your Aglaonema Harlequin plant is starting to die and you are not sure what is causing it, you may wish to check the following;

Over watering

As a tropical plant, Aglaonema Harlequin needs to stay moist. However, when you over water it, the roots will rot and the plant will start growing mold. This will leads to the death of your plant.

Be sure to only water your plant when the dirt is dry, as this will only rot the roots as well. To do this, stick your finger in the soil.

If it is moist, then you should hold off on watering it until the soil is bone dry beneath the surface.

Under watering

This is another common problem for those who own an Aglaonema Harlequin. When you under water your plant, it will get limp leaves and won’t be able to bounce back from this state unless you give it a drink of water.


Your plant will not thrive if the weather is too hot or too cold. Ensure that you keep your plant in room temperature and close to a window for maximum lighting. Too much or too low will harm your plant.

In addition, this plant will start to decline when the nights are cold. You should check that the temperature of your house is the same as that of its environment.

Air circulation

If your air circulation is too low, your plant can suffocate from not getting enough oxygen from the air around it. This will cause it to start growing mold and then eventually die completely.

Light exposure

The light exposure of your plant is also very important for it to grow properly. Too little or too much light will leave your plant with pale leaves, which is a sign that it needs more light or less light.

Root Rot

If you notice leaves that have a greenish mould on them, this is root rot and it needs to be attended to immediately. Root rot is caused when the soil is too saturated with water.

How Often Do You Fertilize Your Aglaonema Harlequin?

Aglaonema Harlequin needs to be fertilized every once in a while, to keep its leaves looking healthy.

You should follow the feeding schedule that is told to you by the manufacturer. Failure to do so can lead your plant’s leaves to shrivel up and die, which is a very sad sight indeed.

A general-purpose houseplant fertilizer, such as our All-Purpose Fertilizer, should be diluted to half its normal strength before being used to fertilize your Aglaonema once per month during the spring and summer months (20-20-20).

During the winter months, when development is often more sluggish, there is no need to apply fertilizer.

You should fertilize your plant with a mild liquid fertilizer such as Indoor Plant Food in order to supply the nutrients necessary for vibrant coloration, sturdy stems and leaves, and robust roots.

Why Is My Aglaonema Harlequin Dropping Leaves?

If your Aglaonema Harlequin is dropping leaves, you should check the following;

Temperature problems

As well as not being too cold or too hot, it should also remain in your room’s temperature range. This will ensure that it receives adequate light and won’t start to show signs of shock if the weather is too hot or cold. High temperatures and too low temperatures can cause your plant to drop leaves.

Air circulation

Air circulation is also very important for your plant to thrive. If the air around your Aglaonema Harlequin is stagnant, it will suffocate and leave it in a state that will not allow it to thrive and thrive.

Light exposure

Your plant needs a lot of light in order to grow properly, so make sure that you provide this for it as much as possible through your window or window-pane.

Too much direct sunlight will cause your plant to drop leaves. If your house is too dark, then try using a large floor lamp to expose more light for your plant.

Improper watering schedule

If you are watering your Aglaonema Harlequin too little or too much, it can cause your plant to lose leaves.

You should be sure to water the soil thoroughly on a daily basis, with any excess water dripping from the soil onto the leaves and then evaporating back into the atmosphere.

Too much fertilizers

Excess fertilizers can cause your leaves to wither and eventually drop. You should always follow the feeding schedule provided for you by the manufacturer to make sure that your plant is fully nourished with all of the vitamins and nutrients it needs.

Pests and Diseases

If your plant is suffering from pests and diseases, then it may try to drop leaves as a way of protecting itself and its other leaves. This makes it very important for you to treat the problem as soon as possible.

Does Aglaonema Harlequin Flowers?

Aglaonema Harlequin is a flowering plant. This means that it will grow and bloom on its own, and if you want to go further, it can also produce seeds.

It is very important to ensure that your Aglaonema Harlequin flowers and then drops all of its seeds before it dies.

Flowers will appear on your plant if it is kept in a warm temperature, indirect light, as well as if you keep the lights on for longer than usual.

In addition, plants typically flower during the spring and summer months when development is more rapid.

In order to produce flowers, you need to feed your plant every so often. You should follow the feeding schedule of your Aglaonema Harlequin as illustrated by the manufacturer. Failure to do so will result in a dead plant, which is very sad.

During the summer months, especially during the springtime when temperatures are warm, the female parts of flowers will appear on your plant. If these do not make it through, they will automatically drop to the ground and begin to ripen.

What Is The Best Soil For Aglaonema Harlequin?

Aglaonema Harlequin is a type of plant that can thrive in many different soil types. You should make sure that the soil you get for your plant has a high aeration rate, as this will allow it to breathe easier. This makes it easy for water and air to pass through the soil, which are essential for your plant to grow properly.

You should avoid using a soil that is compacted and made of clay, as this will restrict the passage of air and water.

Not only will your Aglaonema Harlequin not grow as well, but it may also be more prone to various problems such as root rot.

Well-draining soil is also essential for your plant to thrive. This should allow for the maximum amount of water to pass through easily.

Your Aglaonema Harlequin should be watered regularly, once a week or so, depending on the outside temperature and soil type that you obtain for it.

A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage.

Adding a handful of perlite to regular store-bought potting soil should do the trick.

How Fast Do Aglaonema Harlequin Grown?

Aglaonema Harlequin is a very slow-growing plant that can take up to many years to reach its full height.

In their first year, most Aglaonema Harlequin plants will grow either in a pot or in the ground, depending on your preference.

For best results, it is important to keep the soil moist and to feed it appropriately at regular intervals as outlined by the manufacturer.

To encourage Aglaonema Harlequin to grow faster, you can use fertilizers such as a 20-20-20.

However, you should make sure that your plant is not getting too much or not getting too little water.

How Often Do You Repot Your Aglaonema Harlequin?

Aglaonema Harlequin is a plant that requires repotting seasonally, around every two years.

You should repot your Aglaonema Harlequin only when the plant is in need of it either due to a poor root system or because you are planning on moving it to a bigger pot.

If the roots at the bottom of your pot seem to be dying and you can easily pull them out of the soil, then it is time for repotting.

The ideal time to repot your Aglaonema Harlequin is in the spring and summer months, but you can do it at any time if you feel that your plant is experiencing difficulty growing in its current environment.

You will need to make sure that you have a good variety of potting soil, preferably one with organic or natural material. If your Aglaonema Harlequin is growing in the ground, then regular soil will work well.

It is essential for you to inspect the roots of your plant before repotting. If you cannot see any roots at all, then it is time for your plant to be repotted.

What Is The Ideal Temperature For Aglaonema Harlequin?

To thrive, it is best for your Aglaonema Harlequin to be maintained in a temperature between 65–75°F. Avoid drafty areas and temperatures below 60°F in the winter.

If your Aglaonema Harlequin is outdoors, then temperatures lower than these may be required. The ideal temperature will depend on the weather that you live in, but it should never get too high or too low.

Avoid cold drafts and direct sun during the winter months. High temperatures is also not optimal, as this may encourage death of the plant.

At a soil temperature of 60 degrees Fahrenheit, there will be some growth; but, at any temperature lower than that, there will be very little or no growth.

Additionally, tissue damage as a result of chilling can occur whenever air temperatures drop below 55 degrees Fahrenheit, primarily on Aglaonema Harlequin, but also on other cultivars at 50 degrees Fahrenheit or below.

This is most likely to happen on Aglaonema when the air temperature is below 50 degrees.
