Growth and Size

The Alocasia Cuprea is a great choice for a houseplant due to its small size. It has a height of around a foot and can have even larger leaves.

The plant thrives in a humid climate, making it an excellent choice as a tropical plant. Although it is slightly more moisture sensitive than other Alocasia kinds, other than that, it doesn’t require any different maintenance.


A warm, humid, and moist atmosphere is ideal for flourishing Alocasia plants. The winter environment gets chilly and dry, which is not good for plant growth. In cold weather, they enter a state of self-preservation by going dormant when confronted with such circumstances.

They might lose leaves during this time and look sickly and dwarfed. Do not worry; as soon as the winter ends, they recover to their initial condition.

watering requirements

How frequently should I water Alocasia Cuprea?

Alocasia Cupreas can be a little challenging to water. Overwatering is highly intolerable to their delicate roots. Roots soaked in water will rot soon. It needs to be watered deeply when it is thirsty and dry. Contrarily, the Alocasia Cuprea cannot grow properly when you are not giving it enough water that it needs.

We recommend you use your finger to check the soil moisture before watering. Please water your plant if the top 2 inches of soil are entirely dry. Hold off watering for one or two days until the topsoil is dry, even if it is only a little moist. We recommend using a moisture meter or moisture sensor to make sure if the soil is dry to prevent overwatering.

Signs of both excessive and insufficient watering:

The most prominent sign of over-watering is the lower leaves look yellow and wilted. You need to stop watering the plant and let the soil dry enough to water again. Similarly, if its leaves get pale with time and suffer from limited growth, it means you are not giving this beautiful plant sufficient water.

As soon as you notice these signs, change your watering habit; otherwise, the situation can worsen in a few days.

sunlight requirement

Light Need

Every plant on earth needs a specific amount of sunlight for growth; Alocasia Cuprea is no exception. It needs indirect light to grow healthier. Alocasia Cuprea is highly sensitive to direct sunlight, so don’t forget this jewel in direct sunlight. This plant’s magnificent leaves are susceptible to yellowing from prolonged exposure to sunlight. The leaves may wither and will.

Moreover, this specie of Alocasia will lose its chlorophyll in the absence of light. Its leaves will start losing their green colour. Your plant may die because of it. So, we recommend you place your plant in an east or north-facing window to receive plenty of indirect sunlight. Additionally, you may use artificial light or fluorescent bulbs to provide the ideal amount of light.

humidity and temperature

Humidity and Temperature Requirements:

Alocasia Cuprea loves humidity. It thrives in a humid environment, as it is a tropical plant. This Jewel Alocasia’s ideal humidity is between 80-90%. It would be somehow difficult to maintain this humidity indoors; however, using a humidifier for your plant will be the best option. Otherwise, you can place this plant in the kitchen or near the kitchen, as there is more humidity in the kitchen. If you don’t want to use a humidifier or do not want to place it in the kitchen, then there are other things you can do to maintain this humidity range.

Please set your plant on top of a watered pebble tray to establish a microclimate around your Alocasia. You can also scatter water dishes and jars among your plants.

As for temperature, Alocasia Cuprea grows perfectly at a temperature between 50F to 85F. This can be maintained indoors, but it would not be easy to maintain this temperature outdoors. So, it would be best to place Alocasia indoors, especially in winter. Please do not wait for frosts or cold to move your plant indoors. We suggest you move it in the fall to prevent harm from cold.

soil requirement

Soil Requirements:

Alocasia Cuprea loves moist soil but is sensitive to overwatering, which can cause a root rot disease. Therefore, you shall maintain a well-draining soil for your Alocasia Cuprea. The simplest method to obtain these two qualities is to combine peat moss with Perlite

Perlite and Coco coir are further options. Together, they maintain soil moisture and nutrients for as long as is necessary for a plant to absorb them. Perlite, meanwhile, promotes a quicker release of excess moisture, keeping the soil from becoming wet.

You can also mix the following ingredients to prepare a well draining chunky potting mix for your Alocasias.



Alocasia Cuprea is a small-sized plant and has a slow growth, so repotting it is not much of an issue. It doesn’t need repotting more frequently; you need to repot it for two to three years. Alocasia Cuprea needs repotting only when it becomes rootbound or when the roots start to come out of the holes of pots. As the soil loses its nutrients with time, you can repot it to a newer pot if you want to change the soil.

The best time for repotting Alocasia Cuprea is the spring season, as in the spring season, plants are growing.

Steps to repot Alocasia Cuprea:

  • Firstly, choose a pot that is slightly bigger than the current pot. It will help the plant to grow. The pot should not be larger than 3 inches than the current pot; otherwise, it will cause the issue of too much water at the bottom of the pot.
  • Gently take the plant out of its current pot and slide it out.
  • Once it is removed, check the root ball and roots, they should be healthier. Remove the roots which are turning yellow.
  • Then, gently remove the excess soil from the plant, untangle the roots and prune the plant if needed.
  • Place the plant in the centre of the new container.
  • Add an adequate amount of new soil to the new pot. Avoid covering the plant with so much soil that it cannot breathe. Gently tap the soil to avoid air pockets. 
  • Add some water to your plant and put it away from direct light.


Propagation of Alocasia Cuprea:

Propagation is the method of the multiplication of plants. This can be done by different methods such as division, cutting, layering, crafting, etc. The technique you should use depends on the specie of plant and the required goals such as disease resistance, increased crop production, etc.

propagation of alocasia cuprea or red secret alocasia

The most successful method for the propagation of Alocasia Cuprea is through root division which can be done in the soil as well as water.

Propagation through Roots Division:

The right time to do the division propagation is the spring or early summer season, so keep this in mind. When this plant matures, it creates baby offsets that should be separated from the parent plant to propagate properly.

  • The roots of the Alocasia Cuprea typically overlap when it grows in clusters. Cut a cluster with one or two leaves after gently washing these roots.
  • Take a fresh pot and fill it with the proper soil combination. Add some water to dampen the soil.
  • Create a hole in the middle of the soil and insert the plant into the pot.
  • Place the plant in the soil and gently press the soil to remove any air pockets. But don’t overdo it; otherwise, the roots won’t be able to breathe.
  • Water the plant one more time, and your plant is ready.

Propagating root cutting in water:

Carefully remove the Alocasia Cuprea from its pot and gently shake them to make the roots more flexible. If roots are still overlapping, use isopropyl-sterilized pruning shears to loosen up the roots. Remove the excess soil from the roots. Take a transparent container, and fill it with 75% of tap water. If you doubt this tap water contains chlorine, then allow the tap water to sit for a day.

Put the roots of your plants in this transparent container and set the bowl on the east or north-facing window. Keep replacing the water with fresh water every other week. When you notice that the roots are expanding, prepare a pot with a suitable potting mixture and shift the plant to the new pot, but don’t yet fill it with soil.


Some people debate about the amount of fertilizers this plant needs. However, we suggest feeding the plant according to its needs. Alocasia Cuprea is not a heavy feeder, but it needs more food during the growing season as it will boost its growth.

For all Alocasias, it is ideal to use the balanced houseplant fertilizer in diluted form; the same is true with Alocasia Cuprea. Use it once a month first, then analyze your plant’s health. Increase the frequency to twice a month if necessary. This plant does not need fertilizers in the winter, so stop feeding it in the fall.

maintenance and cleaning


Adequate sunlight, sufficient watering, high humidity, well-draining soil, and diluted fertilizers are the basic needs and tips for Alocasia Cuprea. These fundamental recommendations should help your Red Secret plant flourish. Change each element one at a time if your plant seems to be having trouble so you can determine which thing is affecting its health. 

Alocasia Cuprea is a little plant that reaches a height of one to two feet. Most of its height is made up of its massive leaves. Additionally, it does not grow uncontrollably or spread outward. As a result, pruning is a comparatively minor maintenance task.

However, removing any leaves that were wilting, damaged, discoloured, or old would be preferable. This will help keep your plant healthy. You can leave your plant alone except for that.



According to the ASPCA report, Alocasia Cuprea, like its family members, is toxic for humans and animals when ingested. The plant’s toxicity is due to the presence of calcium oxalate in its parts.

Symptoms of ingestion include stomach discomfort, nausea, and vomiting. While contact, this plant’s sap can irritate. So, gloves should be used when propagating, repotting, or pruning. Stay safe and avoid ingestion.

common problems

Pests and Diseases:

Unfortunately, houseplant pests might attack your Alocasia Cuprea. You must pay close attention to aphids, mealybugs, and spider mites. If you don’t water your plant properly, diseases brought on by overwatering may also cause problems. Spider mites are the most prevalent of the three on Alocasias. 

Neem oil or an insecticidal soap spray might be used as a cure. Any area of the plant that is above the soil is susceptible to assault by mealybugs. Because of their capacity for rapid multiplication, these pests can do a great deal of harm. The female mealybug can produce up to 300 eggs in its lifespan.

On the other hand, aphids like sucking the Alocasia Cuprea leaves sap. These insects only reach a height of about 1/4 inch. However, if there is an infestation, aphids can destroy your plant. Aphids are most active in the spring when their reproduction cycle goes into overdrive.

Leaf spot disease:

Diseases that cause leaf spots harm plants by preventing photosynthesis. Spots might be black, brown, tan, or yellow and have an erratic appearance. Fortunately, the disease only initially touches a small area of the leaves, giving you time to stop it from spreading.

To avoid infection:

  1. Keep your plant separate from other plants.
  2. Trim off any damaged leaves and dispose of them gently once more.
  3. Use 70% isopropyl to sanitize your garden shears properly.

Root Rot:

Overwatering or a soil mixture that retains too much water causes root rot. In both scenarios, water molecules in the soil displace air molecules, making it impossible for roots to breathe. Overwatering negates all your efforts to find a chunky blend. Roots gradually become suffocated, brown, black, and mushy. They could also have an unpleasant odour.

Make sure your potting mix is permeable to avoid this. The soil’s air is increased by amendments like orchid bark, perlite, and charcoal. Only water when the soil has dried out. Water in the mornings; since evaporation happens throughout the day, this lowers the chance of water accumulation in the pot.

Rust Disease:

Rust disease is a fungal disease that affects plants and is spread by spores. The leaves of Alocasia Cuprea will look “rusty” when they are diseased. The rust lesions on your Alocasia Cuprea develop in a fungal cycle and begin as orange or yellow patches on leaf surfaces.

Later, the spots began appearing on the leaves undersides in the late spring. If the rust illness is serious, you must treat it with a fungicide. Also available are bio-fungicides. To prevent further damage to your plant, test the treatment first.

Common Problems:

Other than the diseases mentioned earlier and pests, this metallic plant suffers from other common issues like grey mold, southern blight, powdery mildew, etc. To avoid these issues, keep an eye on your metallic plant to figure it out as soon as possible. Otherwise, these diseases can kill this plant in a matter of days before you even realize what happened to your jewel plant.

Besides this, you must provide this plant with the optimal amount of sunlight, humidity, temperature, soil, and, most important, water.
