Alocasia is a genus from the family Araceae. Native to subtropical and tropical Asia and Eastern Australia, there are over 90 accepted species of Alocasia. Commonly known as Elephant Ear, these plants are widely cultivated as ornamental plants worldwide. Their striking and sometimes large foliage have attracted many plant collectors, making them one of the most sought-after genera of plants.
Alocasia, commonly known as elephant ear plants, are tropical beauties prized for their stunning, often gigantic leaves. With over 70 species, Alocasia are increasingly popular houseplants. However, they can be quite finicky when it comes to care. One of the most important factors in successfully growing these tropical plants is providing them with the right potting mix. This comprehensive guide will teach you everything you need to know about crafting the ideal soil for your Alocasia.
Why Soil Mix Matters for Alocasia
While Alocasia will tolerate average potting soil, they thrive in a customized mix catered to their preferences. Here are some key reasons the right soil is critical:
-
Prevents Overwatering: Alocasia are prone to root rot if their soil stays soggy. A well-draining mix is vital.
-
Provides Nutrients Alocasia are heavy feeders and require a nutrient-rich soil
-
Encourages Healthy Roots The soil needs to strike a balance between moisture retention and drainage for robust roots
-
Maintains Acidity: Alocasia prefer a mildly acidic soil with a pH of 5.5-6.5.
Key Properties to Look for in Alocasia Soil
When creating or buying premixed soil for Alocasia, keep these essential properties in mind:
-
Exceptional drainage: This is crucial to prevent soggy soil. Look for components like perlite, pumice, bark chips, and sand.
-
Moisture retention: While the soil must drain well, it should also retain some moisture. Peat moss and coco coir help with this.
-
Nutrient-rich: The mix should contain organic matter like compost to provide nutrients. Slow-release fertilizer is also beneficial.
-
Aeration: Ingredients like perlite allow air circulation so roots can breathe.
-
Acidic pH: Look for components like peat moss that create a mildly acidic pH of 5.5-6.5.
-
Low-density: Avoid heavy, compacted soil, which smothers roots.
5 Best Soil Ingredients for Alocasia
Here are top-rated components to use in an Alocasia mix:
1. Potting Soil
High-quality potting soil forms an excellent nutrient-rich base. Look for a brand with peat moss to retain moisture.
2. Perlite
Perlite aerates the soil and prevents compacting and sogginess. It’s essential for drainage.
3. Orchid Bark
Orchid bark provides excellent aeration while also retaining some moisture.
4. Peat Moss
Peat moss helps achieve the ideal acidic pH for Alocasia. It also retains moisture.
5. Compost
Compost offers vital organic nutrients. Opt for worm compost which aerates well.
How to Create the Perfect Alocasia Soil Mix
Follow this simple recipe to craft an ideal potting mix:
Ingredients:
- 2 parts high-quality potting soil
- 1 part perlite
- 1 part orchid bark
- 1 part peat moss
- 1 part worm compost
Instructions:
- Combine all ingredients in a large container.
- Thoroughly mix together with your hands or a trowel until uniform.
- Use immediately or store in an airtight container until needed.
This blend perfectly balances drainage, aeration, moisture retention, nutrients, and acidity. The potting soil, peat, and compost offer nutrition, the perlite and bark provide drainage and aeration, and the peat contributes acidity.

Common Problems and Solutions
Even with the proper soil, issues occasionally pop up. Here are some common problems and fixes:
Problem: Leaves yellowing
Solution: Leach excess fertilizer from soil by heavily watering. Apply less fertilizer next time.
Problem: Slow growth
Solution: Repot in fresh soil, as nutrients likely depleted. Begin fertilizing regularly.
Problem: Wilting
Solution: Check for pests, over/underwatering, or root rot. Adjust watering schedule.
Problem: White fungus on soil
Solution: Cut back on watering and make sure pot has drainage. Apply fungicide if needed.
Tips for Repotting Alocasia
- Repot young Alocasia annually in early spring. Mature plants only need repotting every 2-3 years.
- Select a pot one size larger than the current pot. Never pot into a vessel more than 2 inches larger or root damage can occur.
- Carefully remove the entire Alocasia from its pot and loosen compacted roots before repotting.
- Fill the new container 1/3 with soil, place the Alocasia inside, and finish filling.
- Water thoroughly after repotting and allow excess to drain fully.
Aerating, fast-draining yet moisture-retentive soil with abundant organic matter and a mildly acidic pH provides the ideal environment for Alocasia. By crafting and using the proper mix, your Alocasia will be poised to thrive and produce their signature huge, gorgeous leaves that add major tropical flair to any indoor space.
Is it normal for Alocasia to go dormant?
Yes and no. Dormancy in Alocasia is presented through a complete loss of leaves and slowed growth. This usually happens when colder temperatures set in and the sunlight decreases significantly.
You can prevent your Alocasia from going dormant by ensuring that the room temperature is between 16C – 26C (65F – 85F), that there is adequate sunlight, humidity ranges between 35% – 55% if its not in a greenhouse, fertilize if necessary, and that you are watering your Alocasia weekly.
My current collection of Alocasia includes: Alocasia Black Velvet, Variegated Alocasia Frydek, Alocasia Cuprea, Alocasia Frydek, Alocasia Venusta, Alocasia Silver Dragon, and Alocasia Jacklyn.
But my previous Alocasia collection included an Alocasia Polly, Alocasia Mayan Mask, a not IDd Alocasia, and my first Alocasia Jacklyn
What is the difference between Aroid Mix and regular potting mix?
The 2 most common potting mixes you will encounter are Aroid Mix and regular potting mix that you can buy from garden stores. Lets break these mixes down.
Aroid Mix is often very chunky and aerated. It is usually made for plants with significantly thicker roots, making it a great generic soil mix. Alocasia plants have both thin and thick roots; they are also heavy feeders and require more nutrients than Philodendron or Monstera plants which are your most common aroid plants. Aroid Mixes either have minimal organic nutrients or none at all. This leaves you to measure, test, and calculate how frequently you need to fertilize your plant to provide it with the exact nutrients it would typically get in its natural habitat, which can often be difficult if you are a beginner plant parent or just starting out with your first Alocasia.
Regular potting mix recipes like ProMix or Miracle-Gro are cost-effective and easily accessible, making them one of the most common go-to mixes for many plant collectors. Both of these soil mixes are made with very little perlite and very little amount of moisture-retaining components. Perlite is an essential component that helps to increase drainage and aerate the soil, creating air pockets for the development of healthy root systems. Without decent drainage, your plant will sit in wet soil, leading to root rot and, ultimately, your plant dying. Additionally, both ProMix and Miracle-Gro have slow-release fertilizers as the main source of nutrients. Meaning that the potting mix has no organic components to filter or aerate the soil mix as an Aroid Mix or Birdys Plants Alocasia Mix would have.
