Are you looking to add some tropical vibes to your indoor space? Alocasia longiloba, also known as Elephant ear, is a stunning house plant that can bring a touch of the jungle into your home. With its callosal leaves, bluish-green foliage, and silver margins and veining, this plant is a real eye-catcher. But how do you take care of this exotic beauty? In this article, we will explore everything you need to know about Alocasia longiloba, from its care requirements to propagation methods and common issues. So let’s dive in!

Lighting Requirements

Like most house plants, Alocasia longiloba thrives in bright, indirect light. It needs at least 6 hours of sunlight per day to stay healthy and grow properly. However, direct sunlight can scorch its leaves, so avoid placing it in direct sunlight. If you have a south-facing window, it can be an ideal spot for your Alocasia longiloba. If natural light is insufficient, you can supplement it with a grow light placed a few feet above the plant.

Watering Requirements

Proper watering is crucial for the well-being of Alocasia longiloba. It is best to water the plant when the top inch of soil feels dry. Water thoroughly, allowing the excess water to drain out. Be careful not to overwater, as this can lead to root rot. On the flip side, underwatering can cause the plant to droop and its leaves to wilt. Find the right balance by monitoring the soil moisture and adjusting your watering schedule accordingly.

Temperature Requirements

Alocasia longiloba prefers a temperature range of 65°F to 80°F (18°C to 27°C). It is important to avoid exposing the plant to extreme temperatures or drafts. Temperatures below 15°C can cause leaf drop, while sudden temperature changes can stress the plant. Keep it away from cold drafts, heating vents, and air conditioning units to ensure it stays healthy and happy.

Humidity Requirements

As a tropical plant, Alocasia longiloba loves high humidity. In its natural habitat, it thrives in humid environments. To provide the right humidity level, mist the plant regularly or use a humidifier. You can also create a humidity tray by placing a tray filled with water and pebbles close to the plant. As the water evaporates, it increases the humidity around the plant. Aim for a humidity range of 60% to 80% to keep your Alocasia longiloba thriving.

Soil Requirements

When it comes to the soil for Alocasia longiloba, a well-draining mix is crucial. It should be able to retain enough moisture to keep the plant hydrated but not hold on to excess water. You can use a standard all-purpose peat-based potting mix or a mix specifically formulated for aroids. Adding organic matter such as compost can improve moisture retention and provide essential nutrients. Aim for a slightly acidic soil with a pH range of 5.5 to 6.5.

Fertilizer and Nutrient Requirements

To promote healthy growth, fertilize your Alocasia longiloba every two weeks during the growing season. Use a balanced liquid fertilizer that is diluted according to the manufacturer’s instructions. Make sure to fertilize only when the soil is moist, as applying fertilizer to dry soil can burn the roots and cause leaf yellowing. During the dormant season, reduce fertilization or stop it altogether.

Common Pests and Diseases

Alocasia longiloba is prone to certain pests and diseases. Spider mites, aphids, and scales can infest the plant, causing damage to its leaves. Regularly inspect your plant for any signs of pests and take appropriate action if needed. Insecticidal soap or neem oil can be used to control these pests. Root rot can be a concern if the plant is overwatered or if the soil doesn’t drain well. To prevent root rot, ensure proper drainage and avoid overwatering.


If you want to expand your Alocasia longiloba collection or share the plant with friends, propagation is the way to go. Alocasia longiloba can be propagated through division. Carefully remove the plant from its pot and separate the smaller plants or offsets from the main plant. Ensure that each division has its own set of roots. Plant the divisions in separate pots with well-draining soil and provide them with the same care as the parent plant.


While Alocasia longiloba is a gorgeous plant to have, it is important to note that it is toxic if ingested. Keep it out of reach of children and pets to prevent any unwanted accidents. If you have pets that are prone to chewing on plants, consider choosing a safer alternative.


Alocasia longiloba, or Elephant ear, is a stunning house plant that can add a touch of tropical beauty to your indoor space. By providing the right lighting, watering, humidity, and care, you can keep your Alocasia longiloba thriving and enjoy its captivating foliage. Remember to be mindful of its temperature requirements, watch out for pests and diseases, and propagate it through division if desired. With its unique appearance and exotic charm, Alocasia longiloba is a perfect addition to any plant lover’s collection.
