Is Japanese Aralia Fast-Growing?

Is Japanese Aralia Fast-Growing?

The Japanese aralia is a difficult houseplant that requires low temperatures and a high humidity level to thrive.

The Japanese aralia is a fast-growing shrub that can reach a width of up to 18 inches and has broad, hand-shaped, leathery leaves.

They might have a medium green color or have yellow or white stripes running through them.

The severe loss of leaves can be caused by unusually high temperatures throughout the winter, particularly when combined with dry air.

If this occurs, do severe pruning and leave the ground around the plant bare. Remaining from handling newly produced leaves is important since they are easily harmed.

Can Japanese Aralia Get Sunburn?

This evergreen shrub works very well in regions with temperatures that fall between subtropical and temperate.

Despite its widespread cultivation and propagation, the Japanese aralia is most successful in subtropical regions.

This suggests that the ideal environment for aralia plant growth is a shady location where they may get brilliant light that is dispersed.

They risk having their leaves charred if they are left in the sun’s blazing heat for too long.

Unfortunately, farmers’ ignorance is the root cause of a disease known as leaf scorch, which affects Japanese aralias very frequently.

Even if your plant is kept inside, it can still get sunburned if it is kept too close to an open window or if the window itself is facing directly into the sun.

The good news is that sunburn problems may be easily and quickly rectified by simply relocating your plant to a location with more shade.

Because it can survive in low to medium light conditions, the Japanese aralia is an excellent choice for your interior areas.

Will Japanese Aralia Freeze?

Aralia, a plant native to Japan, is one of the few plants valued more for its leaves than its flowers. Anywhere in Texas that experiences freezing temperatures may cause harm to the entire plant; thus, it is important to mulch it properly and place it in a sheltered spot.

When exposed to temperatures of -4 degrees Celsius or lower, these plants take on the appearance of being completely dead; they become nearly completely droopy.

They seem to suddenly get better as the temperature continues to climb.

It’s a defense, and you should disregard it as such. Even a little frost might cause some new growth to get charred if cold weather arrives after an autumn that was unusually warm.

Why Is My Japanese Aralia Turning Brown?

Foliage issues with Fatsia japonica are unavoidable, whether indoors and out. All aralia plant owners should follow the most recent aralia plant care routine.

It is straightforward to repair browning Japanese aralia leaves. Simply identify the source of the problem for simple treatment and restoration of normal plant foliage.

Some of the probable reasons for aralia plant leaf browning are listed below.

Too Much Direct Sunlight

Aralia species flourish in their native environment under the canopy. This indicates that the plant favors indirect direct sunlight for its physiological operations.

Aralia leaf browning is induced by extended exposure to direct sunlight. Sunlight with a high intensity burns the foliage of your indoor plants.

The plant will wilt and die if this situation continues for several weeks or months. The ideal approach is to supply the maximum amount of light.

It is best to keep the houseplant away from direct sunlight. However, it must be placed in an area that gets filtered light.

You may also use artificial lighting to keep the plant from being sunburned. The good news is that aralia plants can thrive in low to medium light environments.

Over Fertilization

The first signs of excessive salt accumulation from fertilizers are brown leaf tips and edges. Unlike other tropical plants, most aralia types do not eat heavily.

However, these houseplants still require fertilizer to encourage growth and health. Too much fertilizer is harmful to the plant.

Excessive salt accumulation in the soil prohibits the roots from performing vital processes such as water and mineral intake.

Aralia plant leaves turn dark at the tips and edges due to dehydration. Flushing the potting soil with enough water can exacerbate the problem.

The best option is to repot the houseplant in new potting soil. Provide the essential conditions and take care to recover the lovely aralia leaves.

Use Of Tap Water

Water from the tap contains a variety of minerals and chemical substances. These substances are harmful to plant health and well-being.

The blackening of aralia leaves after watering might be caused by sodium and chloride chemicals. These chemicals are harmful to the plant and should be avoided.

When watering these houseplants, use distilled or filtered water. Rainwater is another great choice. Improving the water quality of your plant will help keep the leaves from becoming brown.

Too Low Humidity

Aralia plants are endemic to Asia and America’s tropical jungles. High humidity levels are ideal for these tropical plants.

Because of humidity variations, most indoor aralia plants are prone to brown leaf tips and edges. Fatsia japonica leaf issues are caused by low humidity in the air.

If your Japanese aralia leaves are brown, it might be due to a lack of humidity around the plant.

Installing an electric humidifier in the house to boost humidity is the best answer. To avoid more fatsia japonica leaf issues, avoid spraying the houseplant.


Inadequate watering is another cause of your aralia plant’s dark, crispy leaves. The issue is widespread among industrial owners with demanding schedules.

The Aralia plant prefers moderate watering. However, it is dependent on whether the season is growing or dormant. Remember that most houseplants require additional water in the summer.

Inconsistent watering practices are to blame if you observe the tops and edges of your aralia leaf turning brown. Water the houseplant to keep the leaves from becoming brown.

Too High Temperatures

The houseplant is all right with regular temperatures and light levels. However, these conditions should not be too high.

Fatsia japonica is tolerant of higher temperatures, but excessive heat can lead to damage to your plant’s roots. High temperatures will increase the chances of your aralia leaf issues by damaging its leaves over time.

The best way to address this problem is to keep the temperature indoors maintained at a comfortable level, between 60 and 80 degrees Fahrenheit.

How Do I Grow Japanese Aralia From Seeds?

You may start Japanese aralia from seeds if you want to follow the simple route.

That is, in fact, the preferred method of establishing this colorful and dramatic plant.

Although they require regular moisture in the soil and steady temperatures to grow, the seeds have a high success rate.

You may also reproduce them from suckers, but this requires access to a mature plant of the desired variety or cultivar. Here are simple instructions for starting Japanese aralia from seeds.

  • You may obtain the seeds from a trusted internet source, or you can pick the ripe blackberries of a Japanese aralia to extract the seeds. Make sure the seeds you buy online are fresh.
  • To remove the seeds from ripe berries, soak the berries in a jar of water overnight. The next day, you’ll have a jar full of dissolved berry flesh and seeds. To extract the seeds, strain the mesh.
  • Fill a tray with equal parts gritty sand, compost, and soil.
  • Plant one seed in each cell to a depth of one inch. Cover it with dirt and lightly water it to keep the potting mix wet.
  • Place a heat mat beneath the tray and set the temperature to 80°F.
  • Cover the pan with a plastic sheet to keep the soil moist. Keep the tray near a window that receives 6 to 8 hours of direct sunshine every day.
  • Do not allow the soil to dry up while the seeds germinate. To keep the tray moist, sprinkle it once every couple of days.
  • It will take two to four weeks for the seeds to germinate.
  • Once sprouts appear in the soil, remove the plastic cover but continue to water the tray as previously.
  • When each seedling is 3 inches tall, transfer it to its own container filled with the same potting mix.
  • Move the seedlings to their permanent location in the garden whenever the soil temperature outdoors reaches 70 degrees Fahrenheit.

How Cold Can Japanese Aralia Get?

It is often cultivated as an ornamental plant in warm temperate countries where winter temperatures do not typically drop below around −15 °C (5 °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.

How Do You Prune Japanese Aralia?

Because these plants have the potential to reach quite a high height, you shouldn’t be scared to cut them back.

In order to maintain its bushy growth habit and glossy leaves, fatsia has to be trimmed on an annual basis.

In the late winter, just before the plant begins to produce new growth, you can either cut the entire plant down to the ground or leave it alone.

To get a more pleasing aesthetic, clip the leaf stems that grow beyond the boundaries of the plant.

When you prune your plant, you may use the cuttings from the tips to start new plants. In addition, the parent plant’s response will be to get bushier.

What Kind Of Fertilizers Do Aralia Japanese Needs?

Even though it does not require a lot of food, Japanese aralia does better with consistent feedings of fertilizer.

However, there is no need to go crazy with the amount of fertilizer you use. You should have success with using any liquid fertilizer that is gentle and diluted, as well as organic compost tea.

You should begin feeding your plants in the early spring and continue doing so at regular intervals throughout the summer, approximately once every two weeks.

The plant does not require any further fertilization during the fall and winter months.
