How to Grow and Care Alocasia Cuprea Red Secret

This plant, which originates in the tropical areas of Borneo & Malaysia, is known by several other names, including “Mirror Plant” and “Jewel Alocasia.” It can reach a height of one meter. Despite its tropical appearance, this Alocasia stays quite small, making it a great option for terrariums and other small spaces.

When compared to other species of similar flora, the Alocasia cuprea stands out because of its metallic appearance. To describe something as “coppery,” the Latin adjective cuprea is used. The leaves are an enticing trifecta of plum, red, and dark green (nearly black) hues. Its exterior has a metallic sheen, which adds to its already attractive look. Unique and hard to come by, this plant is a treasure for indoor gardeners.

Originally from Borneo’s tropical jungles, this species can be found all over the island today. Even if it’s an excellent houseplant for folks who appreciate the feel of an exotic environment, you must handle it with exceptional care. When it comes to planting toxicity, this one stands out from the others. Due to this, more caution is called for.

Alocasia Cuprea ‘Red Secret’ Care

One of the benefits of Alocasia cuprea is that it does not require as much precision in terms of care. This plant can survive and even thrive with minimal care. Cuprea needs very little special care if you have familiarity with Alocasia plants. The most crucial step is to make sure it doesn’t become soaked through.


The Alocasia Cuprea ‘Red Secret’ needs indirect light in order to grow and thrive. Magnificent as these leaves are, prolonged exposure to light may cause them to turn a dull yellow. As a result, leaf death is a possibility. The plant’s chlorophyll will decay without adequate light. Your plant’s color will fade over time as it gradually loses chlorophyll.

Chlorophyll depletion can be fatal for plants. For optimal light, put your Alocasia cuprea in a northern or eastern-facing window. By doing so, you may make sure it gets enough light to thrive healthily without exposing it to harmful levels of light.

Soil for Alocasia Cuprea ‘Red Secret’

What you need is soil with good drainage for the Alocasia cuprea that you have. For this type of plant care, the plant is about par. Fast-draining soil is not going to be a water hog. It’s possible to oversaturate the soil if excess water isn’t let drain away. There are a number of potentially catastrophic situations that might arise when soil moisture levels are too high. As one of the most devastating plant diseases, root rot must be prevented at all costs (also known as wet feet). Nevertheless, water loss is kept to a minimum in soils with good soil. Moisture loss is little, hence the Alocasia cuprea plant can continue to thrive in it.

You can get the right soil without having to go anywhere special to get it. It can be made at home for much less money than if purchased commercially. If you want to grow an Alocasia cuprea successfully, use a soil mixture that includes both coir fiber and perlite.

Coir, also known as coco fiber, comes from coconuts. Further, it functions similarly to sphagnum peat moss. Due to its higher nutrient content, however, the price is higher than that of peat moss. Coir fiber is useful for promoting rapid water because of its high aeration content. Its pH value is 7, which is the same as the reference value for water. In place of sphagnum peat moss, if you don’t want to spend the extra money, it will serve the same purpose. Coolly, perlite is a byproduct of mining volcanic rock. This lightweight component can hold three times its own weight in water. On the other hand, it drains away any surplus water to prevent pooling.

If you want your Alocasia cuprea to live for a very long time, you need to pay great attention to how often you water it. If you want your Alocasia cuprea plants to thrive, you only need to provide them with an ordinary amount of water. In general, cuprea only has to be watered twice or three times per week, although this will vary according to the season. Before you water the soil once more, it is essential that you wait until at least forty percent of the soil has dried up first. You can verify this by introducing something into the substrate, such as your finger or a stick.

Take care not to overwater the plant. Make sure the container has adequate drainage so that it does not become filled with water that has been added in excess. Always keep in mind that this plant requires only a minimal amount of watering.


Cuprea thrives in hotter environments. That’s why it thrives indoors, where the environment is generally higher, there’s more insulation, and it’s protected from the environment and rain that might otherwise cause it harm. The Alocasia cuprea plant thrives in daytime temperatures between 50 and 85 degrees Fahrenheit (10 and 29 degrees Celsius), and temperature temperatures between 54 and 65 degrees Fahrenheit (12 and 18 degrees Celsius).

If you’ve been taking care of the plant outdoors in the fresh air, remember to bring it inside before bed so that it doesn’t have to face the chill of an indoor environment. Low temperatures are tolerable, but only up to a certain temperature for this plant. Keep it away from drafts if you have to store it inside. For optimal growth, an Alocasia cuprea should be planted in USDA plant hardiness zones 10–11, or in the warmer, sheltered parts of zone 9b.

The Alocasia cuprea can’t survive without a lot of humidity. In order for it to flourish, the moisture must be humid, just like it is in its native lands. This plant thrives best at humidity levels between 80% and 95%.

If you want to feel comfortable in this humidity, a humidifier is a good investment. The relative humidity of an entire space may be raised to the necessary level with the help of a typical humidifier. The pebble method is an additional strategy under consideration. A dish is covered in pebbles that you toss about. First, you want to make sure the pebbles are spread out, and then you’ll fill the tray with water. For this reason, it is crucial that water is prevented from running over the pebbles.

Simply set the potted plant’s container atop the pebbles. Humidity will rise as water evaporates, which is good for your plant. In addition, your plant will be bathed in a sea of moisture thanks to its proximity to the water source. Alocasia cuprea is a popular houseplant, and some people even take it with them to the loo. It’s common knowledge that bathrooms tend to be damp and humid.


In order to get good results growing cuprea, you must invest in premium fertilizer. Because of its voracious appetite, this creature needs a steady stream of macro and micronutrients to thrive. Through the course of the growing season, Alocasia cuprea needs fertilizer applied every two weeks. To give your plant a break from the stress of the growing season, you should cease fertilizing it when winter rolls around.

Before applying commercial fertilizers, it is often advisable to dilute them to around half or one-fourth of their initial strength. This is due to the fact that commercial fertilizers are frequently quite concentrated. As a result of this, the proportion of fertilizer that you apply on your potted Alocasia will be less concentrated, and the plant will be able to absorb more of it. Furthermore, it lessens the likelihood of the fertilizer catching fire.

Potting & Repotting

After two years, the Alocasia cuprea plant will need to have its pot replaced. At this point, your plant has likely reached maturity and outgrown the pot it was originally grown in. It is necessary for the roots to spread out. You should repot your plant into a pot that is only marginally larger than the one it was in previously. Repotting your Alocasia cuprea plant in the spring is the ideal time to do it.


Regular pruning of Alocasia cuprea plants is unnecessary. All that would be required of you would be to propagate cuprea and trim any dead or diseased leaves from time to time. Putting all of the plant’s energy towards producing new leaves is a great help. If the leaves seem like they’re in good shape, there’s no need to prune.

Make sure all of the pruning tools you use are squeaky clean before you start cutting down. Make sure it’s sharp so the wounds you produce are clean and not caused by abrasion. Tasks like pruning and clipping cuprea leaves are best accomplished in the spring. Fast recovery may be expected during this time as your plant shows symptoms of explosive growth.

Alocasia Cuprea Propagation

If you want to propagate the number of Alocasia Cuprea ‘Red Secret’ plants that you have, the most effective strategy would be to divide an existing plant that is already established and bigger. If you choose to split or propagate the plant when it is more mature, not only will you have a substantially better chance of being successful, but you will also have a significantly lower danger of causing damage to the plant that is already present.

The method that you will use to multiply the Alocasia Cuprea ‘Red Secret’ is really not that complicated at all. To begin, remove any containers and superfluous soil. A chopstick may make this process much simpler and will also help you to be more careful while working with the root system.

At this time, you should be able to see the plant’s individual rhizomes. Alocasia Cuprea ‘Red Secret’ plants develop in new rhizomes, which generate new stems for the plant. To the best of your ability, carefully separate these, and if you must cut them, use a clean, sharp blade or a pair of shears. If you must cut them, separate them as gently as possible. After that, the cuttings will need to be simply potted into some high-quality potting mix. After that, the cuttings should be cared for in the same manner as the more mature plants.

Toxicity of Alocasia Cuprea

As a result of its high levels of toxicity, Alocasia cuprea has been linked to a number of serious problems. Possibly high levels of calcium oxalates in its tissues make it toxic to humans and pets. As a result, extreme caution is required whenever it is used. Without this, there will be major problems. If you have little kids or pets, take extra precautions.

Toxicity in Humans and Pets

The needle-like crystals that are plentiful in Alocasia cuprea tissues have the potential to irritate the skin if they come into touch with it. If your skin is particularly delicate, you may get contact dermatitis. Furthermore, if any of the plant material is ingested, severe discomforts such as mouth pain, vomiting, nausea, and diarrhea may develop. These negative effects might occur after ingesting even a modest quantity of the herb.

Toxic adults are just as much at risk from this plant as children are. Because of this, you should always keep it where no one else can get to it. It also helps to designate the plant as a “toxic plant.” Those nearby who aren’t aware of the issue will be made aware of it in this manner.

Many house pets are unknowingly exposed to plant toxins. They have a habit of munching on leaves, and if they do so with your Alocasia cuprea, they will suffer terrible consequences. Calcium oxalate crystals can cause significant irritation to your pet’s tissues if they make their way inside.

Among the symptoms is a pain in the oral mouth and the abdomen. As a result of the swelling, they will have trouble breathing. Due to this, animals kept as pets are in danger of being murdered. If you have cats or dogs at home, you should put this plant where they can’t get to it. If your pet has accidentally ingested anything, you should take them to the nearest veterinary office.
