How Fast Does Japanese Aralia Grow?

This subtropical shrub is a fantastic option for those just beginning out in the profession of plant care and those who have been doing it for some time since it grows quickly and robustly given the appropriate circumstances and requires little in the way of maintenance at the same time.

The Aralia is a relatively simple plant to cultivate, except for the requirement for consistent watering; it may attain a height of between 8 and 12 inches each year if given the appropriate amount of care and is grown in the appropriate environment.

Can Japanese Aralia Grow In Full Sun?

It is best to provide the Japanese Aralia with a medium to low quantity of indirect light. In order for the plant to function properly, it needed to be exposed to sunlight for a minimum of six hours every day.

Put the plant somewhere where it won’t be exposed to direct sunshine and shadow. The plant will eventually get drier if it is grown in complete darkness.

Therefore, the Aralia has to be grown as an indoor plant in order for it to receive the required amount of sunshine.

In most interior settings, these plants would thrive best in front of a window facing east.

How Tall Does Japanese Aralia Grow?

The Japanese aralia is a tropical plant that may be grown as a houseplant, in outdoor pots, or in the garden. It is known for its striking appearance.

Both the popular name Japanese aralia plant and the botanical name Aralia japonica relate to the same broadleaf evergreen. Aralia japonica and Fatsia japonica are the scientific names for this plant.

Huge, deeply cut leaves that may reach a width of up to one foot (30 centimeters) on this plant sit atop long leaf stalks that extend both upward and outward from the base of the plant.

The weight of the leaves causes the plant to tilt to one side is very frequently, and it may grow to a height of between 8 and 10 feet (2-3 m.).

Older plants have the potential to reach a height of 5 meters (15 feet) (5 m.)

How Often Should I Water My Japanese Aralia?

It is reasonable to assume that the Aralia enjoys being near water, given that it prefers to grow in regions that are either near the shore or near large bodies of water.

Keep in mind that this plant is a strong drinker and must be watered consistently.

The make-up of your soil will play a role in determining how often you should “regularly” water your plants.

It may also help you plan out when you should water and how much water you should use so that the soil stays wet. Never allow the soil to become completely dry.

As a matter of thumb, increase the amount of watering you do during the warm seasons and decrease it during the cold seasons.

Watering it once per day or every other day should be plenty during the spring and summer. In the winter, once a week or once every two weeks should be plenty.

Because of its large leaves, the Aralia is much less susceptible to “drowning” and root rot than other plants.

This is because the plant’s roots can drink up large quantities of water to keep the plant’s leaves nourished and hydrated; therefore, one does not need to worry about overwatering the plant.

In the event that there is a prediction of prolonged rain showers, you can also make use of this by positioning your plant comfortably outside under partial cover, just so that it will get a sufficient quantity of water.

Why Is My Japanese Aralia Drooping?

There are one species of broad-leaved evergreen tree known as the Japanese Aralia. This tree belongs to the family Araliaceae.

The scientific name for this plant is Fatsia Japonica, which literally translates to “glossy-leaf paper plant.” It is more often known as the “Japanese Fatsia.”

To this day, the Japanese Aralia is a favorite among most indoor plant owners and gardeners.

It is generally cultivated as an ornamental plant because of its ability to grace and provide even the dullest and most stiff of interior environments with a little bit of life.

When the Aralia Fabian plant leaves begin to droop, this nightmare becomes a reality.

And it’s quite natural for any grower to be baffled as to what may be producing it in the first place.

However, we are all aware that to properly cure one’s plants, one must first determine the root cause of the problem.


If you have been water-depriving your plant for a longer time, it is understandable that the leaves are beginning to droop.

The Japanese Aralia does not like it when its soil is bone dry. It’s a sign that your plant feels threatened by the lack of moisture in its soil and it falls into a state of distress.

If your plant’s leaves are drooping, it’s a sure sign that something isn’t right with the watering.

Aside from falling, the leaves of an underwatered Japanese Aralia will twist and become yellow. Even the plant will begin to lose lower leaves, resulting in defoliation.

Water it when one-third of the soil in your Japanese Aralia container becomes dry. Water them liberally, but remember to drain any excess water through the pot.

Because if the plant is left in wet soil for an extended period of time, a fungal disease may develop.

Too Low Humidity

Japanese Aralia requires moderate to some amounts of humidity, according to research. This might possibly be the cause of your plants’ drooping. Though mature plants can tolerate low humidity, small plants are completely unable to.

You may solve this issue by placing a small tray full of rocks and water beneath your Japanese Aralia pot. Because this water evaporates, creating a high humidity environment for your plant.

Lack Of Sunlight

The second most crucial thing to look for is whether or not the plants are getting adequate sunshine.

Because the Japanese Aralia requires strong but indirect light, and they get drop if not given enough sunshine.

If you are growing them inside, you must place them near a window so they may receive a few hours of sunshine each day.

Root Rot

Finally, but certainly not least, we will address root rot. It is a deadly sickness for your Japanese Aralia.

Because of their fragile root system, the roots easily absorb extra water, resulting in root rot.

Worse, it not only makes the leaves drop but also turns them yellow and prevents the plant from developing at all. Furthermore, the plant begins to decompose from the ground up, with a nasty odor emanating from the roots.

You must carefully remove the plant from the pot without injuring the roots. Then, using a sharp shear or knife, remove the rotting areas of the root.

The rotting sections will be easy to spot since they will be grey and mushy, emitting a foul stench.

After that, apply a fungicide to the roots to successfully eliminate the root rot fungus from your plant.

Nutrients Deficiency

When the Japanese Aralia becomes short on fertilizer, the leaves droop and the entire plant collapses to the ground.

And this problem occurs far more frequently than you would think.

Because potted soil loses nutrients more quickly. As a result, the plant’s leaves become feeble, yellow, and drooping.

You must feed them on a regular basis, especially during their growth season. During the spring and summer, apply a balanced liquid fertilizer to houseplants once a month.

Too Cold Temperatures

During summer, when temperatures begin to rise, houseplants are able to withstand the warmer weather.

But in winter, houseplants simply can’t handle being exposed to these kinds of low temperatures.

As a result, one will notice their leaves droop and curl, causing the entire plant to collapse as well.

If this happens to your Japanese Aralia Fabian tree, you must move it closer to a window or place them in front of a heater during winter.


This is the most frequent cause of Japanese Aralia drooping. Though this tree does not need to be watered as frequently as other houseplants, it must still be watered fairly often.

If you are a beginner with this plant, try and mimic the amount of sunlight and water it was given when you purchased it.

However, in the event that the plant begins to show signs of drooping, care for your plant by watering carefully and only just enough to moisten the soil.

Do not allow any excess water to stay around the roots—because that’s where root rot can begin to develop.

Are Japanese Aralia Poisonous To Cats?

According to ASPCA, Japanese Aralia Fabian is not poisonous to cats.

It is often cultivated as an ornamental plant in warm temperate countries where winter temperatures do not typically drop below around 15 °C (five °F).

The F. japonica plant is winter hardy in USDA Plant Hardiness Zones 8–10 and does best in partial to full shade.

It is possible to cultivate it as an indoor plant, and research has shown that it is effective in removing gaseous formaldehyde from the air inside a building.
