If you’re growing this plant indoors and natural light is limited, you can supplement it with artificial growing lights. Opt for full-spectrum grow lights like LED or fluorescent lights. Position them about 12-18 inches above the plant, and adjust the duration and intensity of the light to mimic natural day and night cycles.

Alocasia Borneo Giant can be grown both indoors and outdoors, depending on your climate. It prefers warm temperatures ranging from 65-85°F (18-29°C) and high humidity levels. If you’re growing it outdoors, make sure to place it in a shaded or partially shaded area to protect it from direct sunlight.

In its natural habitat, Borneo Giant is typically found in rainforests and tropical climates with dappled sunlight. To replicate these conditions, try to maintain a humid environment around the plant. You can mist the leaves regularly or use a humidifier nearby.

Remember to observe your plants response to the light conditions and make any necessary adjustments. It’s always a good idea to closely monitor the plant’s health and provide it with the best possible growing conditions.

Soil Requirements

When it comes to soil requirements, Borneo Giant Elephant Ear prefers a well-draining and nutrient-rich soil mix. It’s important to provide it with a soil that retains some moisture without becoming waterlogged.

One common recipe for a suitable soil mix is to combine equal parts of peat moss, perlite, and organic soil. This mixture helps ensure good drainage while retaining enough moisture for the plant’s roots.

You can also add some organic matter, such as compost or well-rotted manure, to enhance the soil’s fertility and improve its structure.

Another option is to use a high-quality indoor plant potting mix specifically formulated for tropical plants. These mixes typically contain a combination of peat moss, perlite, and other ingredients that provide good drainage and moisture retention.

When planting your Alocasia Borneo Giant, make sure the pot has drainage holes to prevent water from accumulating at the bottom. This will help avoid the risk of root rot. Additionally, remember to allow the top inch or so of the soil to dry out slightly between waterings to avoid overwatering.

Providing your Alocasia Borneo Giant with a well-draining, nutrient-rich soil mix will create a favorable environment for its growth and help ensure its overall health and vitality.


Alocasia Borneo Giant requires consistent moisture to thrive, but they don’t like to be soggy. Water the plant when the top inch of soil feels dry to the touch. During the growing season, you may need to water them more frequently. In contrast, during the dormant season, you can reduce watering.

Here are some watering requirements to keep in mind:

  1. Moist, not soggy: Alocasia Borneo Giant prefers moist soil but not soggy or waterlogged conditions. Overwatering can lead to root rot and other issues. It’s important to strike a balance and allow the top inch or so of the soil to dry out slightly between waterings.
  2. Watering frequency: The frequency of watering will depend on various factors such as the temperature, humidity, and the specific conditions of your plant’s environment. As a general guideline, you can aim to water your Alocasia Borneo Giant when the top inch of soil feels dry to the touch. This typically translates to watering once every 7-10 days, but always check the soil moisture level before watering.
  3. Watering technique: When watering your plant, it’s best to water thoroughly until the excess water drains out from the bottom of the pot. This ensures that the entire root system receives adequate moisture. Allow the water to drain completely and avoid leaving the plant sitting in standing water, as it can lead to root rot.
  4. Humidity considerations: Alocasia Borneo Giant appreciates higher humidity levels. If the air in your home is dry, you can increase humidity around the plant by using a humidifier, placing a tray filled with water near the plant (without the pot sitting directly in water), or misting the leaves regularly. These methods can help create a more favorable growing environment for your Alocasia Borneo Giant.

By monitoring the soil moisture and adjusting your watering routine accordingly, you can ensure that your Alocasia Borneo Giant receives the right amount of water to thrive while avoiding water-related problems.


Alocasia Borneo Giant requires regular fertilization to grow healthy and strong. During the growing season, which is typically spring and summer, you can fertilize your Alocasia Borneo Giant every two to four weeks. This helps provide a consistent supply of nutrients for healthy growth. In fall and winter, when the plant is in its dormant phase, you can reduce or halt fertilization.

A balanced, water-soluble fertilizer with equal proportions of nitrogen (N), phosphorus (P), and potassium (K) is suitable for Alocasia Borneo Giant. Look for a fertilizer formulated specifically for indoor tropical plants or one with a ratio of approximately 10-10-10. This balanced formulation ensures that the plant receives a good overall nutrient supply.

Follow the instructions on the fertilizer package for the correct dilution ratio. It’s typically recommended to use half the recommended strength to avoid over-fertilization, which can harm the plant. Apply the diluted fertilizer to the moist soil, making sure to avoid getting it on the leaves as it can cause burn marks.

If you prefer organic options, you can use a slow-release organic fertilizer or organic compost. These provide a gradual release of nutrients over time, promoting healthy growth.

Cut back the stems to a few inches above the soil level. This will encourage new growth from the base of the plant, resulting in a bushier and healthier appearance.
  • Timing: It’s generally recommended to prune your plant during the growing season, which is spring and summer. The plant is more actively growing during this time, and it can recover more quickly from pruning.

Remember to always use clean and sterilized pruning tools to minimize the risk of spreading diseases.

NOTE: Be mindful of the sap that the plant may release when cut, as it can cause skin irritation. It’s a good practice to wear gloves and wash your hands after pruning.


If you want to propagate your Alocasia Borneo Giant, there are a few things you need to know.

First, I make sure the stock plant is healthy and has enough energy to produce new growth. I check for signs of pests or disease and make sure the plant is well-watered and fertilized. I also wait until the plant has produced a few new leaves, as this indicates it is in a growth phase and will be more likely to produce new shoots.

Here’s a step-by-step guide on two common propagation techniques:

Division Method:

    • Choose a healthy and mature Mother plant to divide.
    • Carefully remove the plant from its pot and gently shake off excess soil to expose the rhizome (thick underground stem).
    • Locate natural divisions or “pups” on the rhizome. These are smaller offshoots with their own roots.
    • Use a sharp and sterile knife or garden shears to carefully separate the pup from the main rhizome. Make sure each division has a portion of the rhizome and healthy roots.
    • Plant the divisions in separate pots filled with well-draining soil. Bury the rhizome just beneath the soil surface and position the roots downwards.
    • Place the newly potted divisions in a warm and humid environment with bright, indirect light. Mist the leaves regularly and provide gentle care until they establish themselves.

Stem Cutting Method:

      • Select a healthy stem from your Alocasia Borneo Giant that has multiple leaves.
      • Using a clean and sharp knife, make a clean cut just below a leaf node (the area where a leaf attaches to the stem).
      • Prepare a small pot with well-draining soil, such as a mixture of peat moss and perlite.
      • Dip the cut end of the stem in rooting hormone (optional but can aid in root development).
      • Create a hole in the soil with a pencil or your finger and gently insert the stem cutting into the hole.
      • Firmly press the soil around the cutting to secure it in place.
      • Place the pot in a warm and humid location with bright, indirect light.
      • Mist the cutting regularly to maintain humidity and keep the soil slightly moist.
      • Over time, the cutting will develop roots and new leaves, indicating successful propagation.


After propagating my Alocasia Borneo Giant, I make sure to continue providing it with proper care. This includes regular watering, fertilizing, and monitoring for pests or disease. I also make sure to give the plant enough space to grow and develop, as it can quickly outgrow its pot.

Keep in mind that not all divisions or cuttings may be successful, so it’s recommended to propagate multiple pieces to increase the chances of success.
