If you have recently expanded your plant collection by adding an Alocasia to it, then the above and many more questions might be on your mind. Fret not, this article is exactly for you as in it you will find all the care requirements of an Alocasia.
Caring for an Alocasia indoors is both easy and complicated. The plants from the Alocasia genus are usually not considered beginner-friendly. This is not because the plants require any special care but because Alocasia wants its owner to stay on top of its needs. This complete Alocasia care guide will cover all the things you need to know to help you keep your Elephant Ear happy, healthy, and thriving.
You probably have heard of many different Alocasia species, to name a few: Alocasia Polly, Frydek, Alocasia Dragon Scale, Alocasia Variegata, Wentii… the good news is that they all pretty much have the same care needs, phew!
The Alocasia genus consists of 97 species, which are native to the sub- and tropical regions of Asia and Eastern Australia. They all are part of the Araceae family and have pretty much identical care requirements. The plants grow from a rhizome or a tuber and are perennial but can (and most do!) go dormant during the colder seasons. Alocasia are flowering plants but due to them not being very tolerant to environmental stress or care-mishaps, their blooms are rarely seen indoors. The foliage of an Alocasia resembles the shape of an elephant’s ear, hence their name, and their leaves can reach the whooping 20 to 90cm in length!
Alocasia are a top choice for many plant enthusiasts because of their gorgeous and unique foliage. If you have an Elephant Ear at home that too has won your heart, read on to find out how to care for an Alocasia to ensure that the plant-diva will grow and thrive.
Alocasias, also known as elephant ear plants, are tropical beauties prized for their stunning, often gigantic leaves With their showy foliage, alocasias make a dramatic statement in any indoor or outdoor garden
However, to keep your alocasia thriving, you need to choose the perfect soil. I’m here to share everything you need to know about picking the right potting mix for your alocasia.
An Overview of Alocasia Care
Before diving into soil specifics, let’s do a quick alocasia care overview
-
Light: Bright, indirect light indoors. Some direct morning sun is tolerated. More light outdoors.
-
Water: Keep soil consistently moist but not soggy. Water when the top 1-2 inches of soil dries out.
-
Humidity: High humidity is adored. Misting leaves and grouping plants helps boost moisture.
-
Temperature: Warm temps between 65-85°F are ideal.
-
Fertilizer: Feed every 2-4 weeks in the growing season with a balanced liquid fertilizer.
-
Repotting: Repot when pot-bound, usually every 2-3 years.
Now that we’ve covered the basics, let’s explore how to choose the perfect soil.
Well-Draining and Aerated Soil is Essential
If I had to choose one non-negotiable for alocasia soil, it would be stellar drainage.
Alocasias hail from tropical rainforests where deluges of rain are followed by warm sun. Their roots demand moisture yet abhor sogginess.
Here are some disastrous things that can happen in dense, compacted, poorly-aerated soil:
- Fungal infections like root rot
- Suffocated roots unable to absorb oxygen
- Waterlogging
- Slow growth
- Drooping, yellowing leaves
- Nutrient deficiencies
To avoid these nightmares, you need a lightweight, loose, and airy soil mix. Here are some great additives to create an open, porous texture:
- Perlite
- Pumice
- Coarse sand
- Orchid bark
- Expanded clay pellets (LECA)
- Pine bark
- Coconut coir
A blend containing several of these ingredients will yield a beautifully airy, free-draining mix.
Moisture-Retention is Also Key
While alocasias demand swift drainage, they also appreciate their soil retaining some moisture. This mimics their natural habitat where dampness lingers between rainstorms.
Here are some signs your soil is too dry:
- Wilting
- Crispy leaf edges
- Slow growth
And symptoms of excessive dryness:
- Drooping and yellowing leaves
- Leaf drop
- Stunted growth
- Plant decline
To prevent underwatering, incorporate moisture-retaining amendments into your soil recipe. Helpful options include:
- Peat or coco coir
- Compost
- Worm castings
- Sphagnum moss
- Shredded tree bark
These organic materials act like little sponges, holding onto water to quench your alocasia’s thirst between waterings.
Nutrient-Rich Components Feed Healthy Growth
While drainage and moisture-retention are most critical, you also want a nutritious soil mix. This gives your alocasia the essential elements it needs for vigorous leaf growth.
Some nutrient-supplying ingredients to use include:
- Compost
- Worm castings
- Plant or animal manures
- Peat or coco coir
- Espoma Organic Potting Mix
You can also add a balanced liquid fertilizer every few weeks during spring and summer. This is especially helpful in leaner, fast-draining mixes.
The Perfect Potting Mix Recipe
Now let’s discuss how to blend the perfect soil recipe.
Here is an ideal alocasia soil mix:
- 2 parts peat moss or coco coir (moisture-retention)
- 2 parts perlite or vermiculite (aeration & drainage)
- 1 part compost, worm castings, or manure (nutrition)
- 1 part orchid bark or charcoal (aeration)
Here are some other excellent store-bought options:
- Espoma Organic Potting Mix
- FoxFarm Ocean Forest Potting Soil
- Miracle-Gro Indoor Potting Mix
Whichever route you go, make sure your blend contains a good ratio of drainage, moisture-retention, and nutrition. This mimics the humid, organic-rich, free-draining soils alocasias thrive in outdoors.
Other Helpful Tips
Here are a few other tips for choosing the perfect potting mix:
-
Use a soilless, peat or coconut coir-based mix for the best drainage and consistency. Avoid heavy garden soil.
-
Consider the alocasia variety. Some like more moisture than others. Adjust additions accordingly.
-
For moisture-loving varieties, add extra peat or coco coir. For drier-tolerant types, add more perlite or orchid bark.
-
Test drainage by watering the mix. It should drain freely yet still feel lightly damp.
-
Add lime if needed to reach a slightly acidic pH around 6.0-6.5.
-
Re-pot annually to refresh the soil and provide room for the expansive roots.
Ready to Pick the Perfect Soil?
By now you should feel fully equipped to put together the ideal potting mix for your beloved alocasia!
Remember, a lightweight, nutrient-rich blend of porous, fast-draining components mixed with moisture-retaining ingredients is key. This gives those thirsty roots the balance of air, nutrients and dampness they crave.
With a custom soil blend made for its needs, your gorgeous alocasia will thank you with vigorous growth, huge leaves, and sensational style!
Rotating Your Alocasia Ensures Proportionate Growth
Your Alocasia will always turn itself in the direction where the light is coming from, so make sure that you periodically rotate the plant, to ensure that all the leaves are getting a good amount of light and thus, encourage your Alocasia to grow proportionally on all sides. Alocasias are also notorious for dropping leaves that are not receiving adequate light, which is another good argument to consider rotating your plant every couple of days or so.
1 How to Identify & Treat Pests on an Alocasia
Although rarely, spider mites and thrips seem to be particularly attracted to Alocasias. Spider mites and thrips are a nuisance to deal with but if they are caught on early, you would be able to easily save your Elephant Ear from pests. Thus, a good habit for any plant parent to develop is to check your plant once a week throughout for any signs of unwanted visitors.
Is your Alocasia looking sad and wilting and you have already excluded every possible environmental factor? Then pests could be the reason why your Alocasia is not feeling so well. The most common pests that are plaguing Alocasias grown indoors are spider mites and thrips.
The damage from both above mentioned pests commonly appears on the underside of the Elephant’s Ear leaves. If you find that your Alocasia is indeed, plagued by an infestation, your first step should be to inspect nearby plants and isolate all affected ones. Next on, try to use a gentle, natural insecticide like neem oil or home-made insecticidal soap. Make sure to cover the entire plant’s leaves, especially the undersides, and repeat as necessary.
