Alocasia Care 101: How to Keep Your Plant Happy and Healthy

Alocasia Care

Alocasia plants, also known as elephant ear plants, are a group of tropical plants that are highly prized for their large, striking leaves and unique foliage patterns.

These plants are native to tropical regions of Asia and are often grown as houseplants or as ornamental plants in gardens. Alocasia plants require specific care to thrive and produce healthy foliage, making it essential to understand their specific care requirements.

All About Alocasia

Alocasia plants belong to the Araceae family and are known for their large, heart-shaped leaves. These plants are typically grown as indoor plants and can add a touch of the tropics to any space.

There are over 70 species of Alocasia, each with unique leaf shapes, colors, and patterns. Alocasia plants can be found in a variety of colors, including green, black, purple, and silver, and can grow up to six feet tall.

When to Plant Alocasia

Alocasia plants can be planted at any time of the year, but they thrive best in warm, humid conditions. It is best to plant Alocasia in the spring or summer, as this is when they will have the most access to sunlight and warmth.

Alocasia Care

Alocasia plants require specific care to thrive. These plants prefer bright, indirect sunlight and warm, humid conditions.

Alocasia plants should be watered regularly, but not overwatered, as this can lead to root rot. It is also important to ensure that the soil is well-draining to prevent water from accumulating around the roots.

Light and Temperature

Alocasia Care

Alocasia plants prefer bright, indirect sunlight. They can tolerate some direct sunlight, but too much can damage the leaves.

Alocasia plants also prefer warm temperatures, ranging from 65 to 85 degrees Fahrenheit. They can tolerate temperatures as low as 60 degrees Fahrenheit, but they should be protected from drafts and cold temperatures.

Alocasia Care

Alocasia plants should be repotted every two to three years, or when they outgrow their current pot. It is important to choose a pot that is slightly larger than the current pot and has good drainage. Alocasia plants can be propagated by dividing the plant during repotting.


Alocasia plants can be propagated through division or through stem cuttings. Division is the easiest method and should be done when repotting the plant.

Simply remove the plant from its pot and gently separate the roots into smaller clumps, making sure each clump has a healthy rhizome and a few leaves. Plant each clump in a separate pot with fresh potting soil.

Stem cuttings can also be taken, but they can be a bit more challenging. Select a healthy stem with at least one leaf and cut it just below a node.

Dip the cut end in rooting hormone and plant it in a pot with well-draining soil. Keep the soil moist and the plant in a warm, humid environment until it roots and starts to grow.


Alocasia Care

Pruning alocasia plants is important to maintain their size and shape. It’s also necessary to remove any dead or damaged leaves or stems. Use a sharp, clean pair of scissors or pruning shears to make clean cuts. Avoid cutting too close to the stem, as this can damage the plant.

Harvesting and Storing Alocasia

While alocasia plants are not typically grown for their edible parts, some species, such as Alocasia macrorrhizos, have edible corms (swollen underground stems).

These corms can be harvested when the plant is dormant in the winter. Carefully dig up the corms, being sure not to damage the roots, and wash them thoroughly. They can be stored in a cool, dry place for several months.

Troubleshooting Alocasia Problems

Growing Problems

One of the most common problems with alocasia plants is yellowing leaves. This can be caused by overwatering, underwatering, poor drainage, or pests.

Check the soil moisture level and adjust watering as needed. Make sure the plant is in well-draining soil and consider repotting if the soil is compacted or waterlogged. Check for pests, such as spider mites or mealybugs, and treat as necessary.


Alocasia Care

Alocasia plants are susceptible to a variety of pests, including spider mites, mealybugs, and scale insects.

These pests can cause yellowing leaves, stunted growth, and other issues. Check the plant regularly for signs of infestation, such as webbing, sticky residue, or small bumps on the leaves or stems. If pests are present, treat with an insecticidal soap or neem oil.

Alocasia plants can be prone to fungal diseases, such as root rot and leaf spot. These diseases can be caused by overwatering, poor drainage, or humid conditions.

To prevent these diseases, avoid overwatering and make sure the plant is in well-draining soil. Keep the leaves dry and provide good air circulation around the plant. If disease does occur, remove infected leaves and treat with a fungicide.

Frequently Asked Questions

Where should Alocasia be placed in a house?

Alocasia plants prefer bright, indirect light, so they should be placed in a well-lit area of the house that receives plenty of natural light, but not direct sunlight. Alocasia can be placed near a window that gets bright, indirect light, or in a room with plenty of natural light.

However, it's important to note that direct sunlight can scorch the leaves of the plant, so it's best to avoid placing it in a spot where it will receive direct sun for extended periods.

Why do Alocasia leaves turn yellow?

Here are some common reasons why Alocasia leaves turn yellow:

  1. Overwatering: Alocasia plants prefer moist, well-draining soil, but they don't like to sit in water. If the soil is constantly wet, the roots can become waterlogged, which can lead to yellowing leaves. Overwatering can also cause root rot, which is a serious condition that can kill the plant.

  2. Underwatering: On the other hand, if the soil is too dry, the plant can become dehydrated and the leaves can turn yellow. Alocasia plants prefer to be watered when the top inch of soil feels dry to the touch, so it's important to check the soil moisture regularly and water as needed.

  3. Pests: Alocasia plants can be susceptible to pests like spider mites, mealybugs, and scale insects. These pests can damage the leaves and cause them to turn yellow. Check the plant regularly for signs of pests, such as webs or sticky residue, and treat as needed.

  4. Disease: Yellowing leaves can also be a sign of disease, such as bacterial leaf spot or fungal infections. These diseases can be caused by overwatering, poor air circulation, or high humidity levels. If you suspect your Alocasia has a disease, it's best to isolate the plant and treat with a fungicide or other appropriate treatment.

  5. Natural aging: Finally, it's important to note that some yellowing of leaves is a natural part of the plant's growth cycle. As older leaves die off, they may turn yellow and fall off the plant. This is normal, and shouldn't be a cause for concern unless it's happening to a large number of leaves at once.

To diagnose the cause of yellowing leaves on your Alocasia, it's important to consider factors such as watering habits, pests, and disease. Once you've identified the cause, you can take steps to treat the issue and prevent further damage to the plant.

What is the lifespan of Alocasia?

In general, Alocasia plants can live for several years with proper care and maintenance.

What does an overwatered Alocasia look like?

Here are some signs to look for that indicate an overwatered Alocasia:

  1. Yellowing leaves: One of the first signs of overwatering in an Alocasia plant is yellowing leaves. The leaves may turn yellow and then brown as the problem worsens. This is because overwatering can cause the roots to become waterlogged and unable to absorb nutrients properly, which can lead to the leaves dying off.

  2. Wilting leaves: Overwatered Alocasia plants may also have wilting leaves, which can be a sign of root rot. The plant may look limp and the leaves may be drooping or curling.

  3. Mushy stems: When an Alocasia is overwatered, the stems may become soft and mushy to the touch. This is because the plant is unable to properly absorb water and nutrients, which can cause the stem to weaken and decay.

  4. Root rot: If an Alocasia is overwatered for an extended period of time, it can lead to root rot. This is when the roots become waterlogged and begin to rot, which can cause the plant to die. Signs of root rot include brown and mushy roots, foul odor, and poor growth.


In conclusion, alocasia care requires attention to light and temperature, water and humidity, soil, fertilization, repotting, propagation, pruning, harvesting and storing, and troubleshooting problems. With proper care, alocasia plants can thrive and bring beauty to any indoor or outdoor space.
