Soil Requirement

You should give your Alocasia cuprea a well-draining soil because it is prone to overwatering and root rot. Combining peat moss and perlite is the simplest approach to get these two characteristics. However, there will always be an alternative if you don’t have anything on hand.

You can also use coco coir and perlite. They work together to keep moisture and nutrients in the soil long enough for the plant to absorb them. Meanwhile, the perlite allows excess moisture to drain more quickly, preventing the soil from becoming soggy.

Water Requirement

This type of Alocasia is a little more moisture sensitive than the others. As a result, avoid soaking the soil in waterInstead, attempt to water without soaking deeply. When the soil is too thick to breathe, oxygen cannot pass through, causing your plant can’t breathe if they don’t get enough oxygen. And your plant requires oxygen just as much as it does with light!

Always remember that overwatering is hugely harmful to the Jewel alocasia since it can cause root rot. If root rot is not treated quickly, all of the roots will rot. Underwatering the plant, on the other hand, can be fatal to the plant. 

To cure this problem: Water your Alocasia cuprea plant two to three times per week on average. To avoid overwatering, check the soil once more before watering it. To prevent root rot, allow the soil to dry between waterings.

Lighting Requirement

The beautiful leaves of this Mirror plant are prone to fading when exposed to direct sunlight for an extended period. If the leaves are tolerated, they will eventually die. Always note that: how much or how little light the plant receives can affect the hue of its leaves. 

The plant’s chlorophyll will deplete if it is not exposed to sunlight, on the other hand. The green of your plant fades as it loses chlorophyll. To cultivate the Alocasia cuprea plant effectively, place your plant in a location that can receive bright indirect light if you want to treat them as an indoor plant.

You can also set the Alocasia cuprea in either an East or North-facing window. This makes sure it gets enough light to thrive but isn’t receiving too much light.

Temperature Requirement

The Alocasia cuprea plant requires a temperature range of 50-85 degrees Fahrenheit (10-29 degrees Celsius) during the day. On the other hand, it requires a temperature of 54-65 degrees Fahrenheit (12 to 18 degrees Celsius) at night.

Pro tip: Keep your Alocasia cuprea away from drafts since they don’t enjoy being chilly. Keep them also away from radiators and heating systems because they can also dry out. Therefore, before the fall, remember to move them to some warm areas. This is especially crucial for plants that are grown outside.

Humidity Requirement

To keep this beauty happy, it has to be kept at a moisture level of at least 80%. However, this amount of humidity is impossible to achieve in a home, so you’ll need to invest in a humidifier to keep your Alocasia Cuprea happy. But! Don’t worry if you don’t have anything on hand.

As we saidthere is always an alternative

The pebble tray method can be used! Fill a tray halfway with pebbles. Then, fill it with water after the pebbles are in place. The water should not be able to pass through the pebbles. As the water evaporates, humidity is created for your plant.

And because it’s so close to your plant, it’ll be surrounded by all that moisture. Or!

group of plants

You can put your plants in groups. Plants that are grouped have a tremendous amount of moisture accessible in their environment. So, to ensure that the humidity level is maintained, group a few plants together.


Fertilizer Requirement

The Alocasia cuprea plants are heavy feeders. And fertilizers are a necessary component of a healthy plant. For the Mirror plant, an all-purpose houseplant fertilizer is a suitable option. Before giving it to your plant, dilute it to half strength.

Do not, however, overfeed it.

During the growing season, fertilize your plant every two weeks. During the winter, do not fertilize the plant. It’s because the salt from the fertilizer will build up on the plant’s leaves, causing them to burn. 

Here’s a pro tip: Flushing the soil every 3 to 4 months to remove excess salt buildup is a good idea because of the heavy feeding.


We are now in the exciting part: replicating our beauties! I know you also want more of this kind of Alocasia. That is why we’re here to tell you how. Propagating Alocasia cuprea is through root division.

It is the ideal method to propagate this plant. Here’s a little tip: When you repot the plant, it’s the most excellent time to reproduce it. For this plant doesn’t like being moved, might as well take that as an advantage. 

So, here is the process:

  • Take the Alocasia cuprea plant out of its pot. Remove the plant with care, being careful not to damage the roots.
  • Gently separate the baby offsets or roots from the parent plant.
  • If shaking doesn’t bring you the roots you need, cut a clump with a pair of disinfected pruning shears. So, sanitize your pruning shears beforehand.
  • Prepare the soil and the pot. The bottom of the container should have drainage holes, and the soil should have a neutral pH level. Do not overfill the pot with soil.
  • Plant the new roots or the baby offset gently so that the roots are not injured. Make sure the soil surrounding them is packed.
  • Place the new plants at a window that faces East or North. Treat the plant in the same way that you would a mature plant. Then, in a few weeks, you will see that the plant is thriving.

Growth Zone

In USDA Growth Zones 3 to 11, the majority of Alocasias are hardy.


The Alocasia cuprea should be planted in a pot that is not too big. A large pot’s potting mix will take too long to hydrate and subsequently dry, perhaps resulting in overwatering. After two years, the Alocasia cuprea plant can be re-potted.

At that time, the plant is mature and too big for its initial pot. The roots must also spread out. Place your plant in a pot that is just a smidgeon larger than the original.

Pro tip: Repotting your Alocasia cuprea plant is best done in the Spring.


Alocasia cuprea is a tiny plant that grows between 12 and 18 inches tall. Its enormous leaves take up the majority of its height. Furthermore, it does not expand outwards or develop out of control. So when it comes to pruning, this makes it relatively minimal maintenance.

However, it would be best if you pruned any leaves that are old, discolored, damaged, or withering. This will maintain your plant in good shape. Aside from that, you can leave your plant as is.

Mealybugs, spider mites, and aphids are the most common pests that attack your Alocasia cuprea. As a result, it’s critical to frequently check your plant’s leaves for them on both the front and back sides. Use insecticidal soap and water or neem oil to treat.

Because the treatment does not eliminate them, you must be consistent. It usually takes a few weeks for the problem to be resolved. Many plants are afflicted with crown, stem, and root rot. This can happen to your Alocasia plant due to a fungus in the soil causing harm to the crown, stem, or roots.

Wet circumstances and heavy soil frequently cause this disease, and it has detrimental consequences for the plant. You must ensure that the affected plant is removed from the infected soil and placed in improved soil that is not infected with fungus. You should apply a fungicide to the soil and soak it twice every 30 days at the very least.

Trim back any injured foliage to ensure that only healthy foliage remains. Rep this procedure until only healthy foliage remains.
