Using LECA (lightweight expanded clay aggregate) as a soilless substrate can provide many benefits to alocasia or arrowhead plants. LECA can help improve drainage, aeration, and reduce the risk of overwatering. Many plant lovers are switching to LECA to achieve optimum growth for their alocasia.
LECA is an inorganic growing medium made from porous clay spheres (85% air space) that functions as both a soil substitute and a hydroponic medium.
When used as a growing substrate for alocasia, LECA provides numerous advantages over soil due to its excellent drainage, aeration, and water retention properties. This allows alocasia roots to obtain the right amount of oxygen and moisture to thrive.
In this blog post, we will explore the benefits of using LECA for alocasia plants and how to care for them while planting and growing in LECA. We will discuss how LECA works to improve growth conditions for alocasia and provide actionable tips to maximize the success of LECA culture for alocasia plants.
By following the instructions and recommendations covered here, you can give your alocasia the best possible chance at optimum health and performance in an inorganic LECA substrate.

What Is LECA and How Does It Work for Alocasia Plant?
As mentioned in the introduction, LECA refers to Lightweight Expanded Clay Aggregate, an inorganic media made from expanded clay pellets. Let’s first look at what LECA is before discussing how it works for alocasia plants.
LECA is produced by heating clay at high temperatures which causes it to expand and form small, lightweight spherical pellets. These pellets have a high porosity of about 85%, meaning there is plenty of space for air and water within the substrate. The large pore space allows for good drainage and oxygen diffusion to plant roots while still retaining enough moisture for proper hydration.
For alocasia plants grown in LECA, the porous clay spheres provide several key benefits. First, LECA’s excellent drainage prevents root rot by eliminating stagnant water around the roots. Second, the ample pore space allows for increased gas exchange which supplies abundant oxygen to the alocasia roots for optimum growth and function. Finally, LECA is able to hold an appropriate amount of water to keep the roots of the alocasia hydrated without becoming saturated.
In summary, LECA works for alocasia by mimicking the properties of ideal soil. The unique combination of drainage, aeration and water holding capacity in LECA matches the needs of alocasia roots, helping the plants thrive even in an inorganic substrate.
In the next section, we will discuss specific advantages of using LECA for alocasia plants including improved drainage, aeration for optimum growth and reduced risk of overwatering.

Advantages of using LECA for alocasia plant
As we learned in the previous section, LECA works well for alocasia plants by providing optimum drainage, aeration and moisture retention. These properties of LECA confer several key advantages for alocasia growth and health.
One of the biggest benefits of using LECA for alocasia is improved drainage. Unlike soil which can become waterlogged, LECA allows excess water to drain quickly thanks to its porous structure and large pore space. This prevents root issues caused by poor drainage like root rot and fungal infections. For alocasia plants that are prone to root problems due to infrequent or excessive watering, LECA can be a life-saver.
Another major advantage of LECA is increased aeration of the root zone. The roughly 85% air space within LECA gives alocasia roots plenty of oxygen for maximum performance. Ample oxygen in the root environment helps stimulate healthier, stronger root growth in alocasia plants. In turn, the plant exhibits improved nutrient and water uptake leading to better foliage growth above ground.
A third benefit of LECA for alocasia is that it reduces the risk of overwatering. Unlike soil-based substrates, LECA drains quickly so it does not hold excess moisture that can damage roots. This allows alocasia growers to water their plants as frequently as needed without fear of causing root rot from soggy conditions. Overwatering is a common issue for alocasia owners, but LECA helps mitigate that risk for happier, healthier plants.
In summary, the key advantages of LECA for alocasia plants revolve around its ability to provide optimum drainage, aeration and moisture levels – exactly what alocasia roots require to thrive. In the next section, we will cover how to transplant and care for alocasia plants growing in LECA.

How to Use LECA for Alocasia Plant?
Now that we understand the benefits of LECA for alocasia plants, let’s cover how to use this growing medium properly for optimum results. There are a few main steps to planting and caring for alocasia in LECA: prepping the LECA, transplanting the plant, and watering and fertilizing.
To prepare the LECA, simply rinse and drain the clay balls thoroughly to remove dust. Then allow them to air dry until you’re ready to use them. Some growers also mix perlite or vermiculite into the LECA to improve aeration and water retention. A typical ratio is 2 parts LECA to 1 part perlite.
When transplanting an alocasia into LECA, start by removing as much of the original soil from the roots as possible. This will allow the roots to properly establish in the new medium. Place the LECA into your preferred container and arrange the clay balls to provide good spacing around the root ball. Gently lower the root ball into place and fill any gaps with additional LECA.
Once planted in LECA, water your alocasia thoroughly to settle the medium and saturate the roots. Going forward, the watering frequency will depend on the size of the plant and container plus environmental conditions. Check the LECA a few inches below the surface to determine if it is dry before watering again. Apply a dilute liquid fertilizer every 1-2 weeks during the growing season. As with soil, stop fertilizing alocasia in LECA during winter.
In summary, the main aspects of using LECA for alocasia involve preparing the medium, transplanting the plant properly, and adjusting your watering and fertilizing schedule to match the needs of LECA. In the next section, we’ll cover specific tips for best results growing alocasia in LECA containers.

Tips for using LECA for alocasia plant
Now that you understand how to transplant and care for alocasia plants in LECA, here are some tips to ensure your plants thrive in this growing medium:
Choose the right size of LECA balls for your Alocasia container. Larger LECA is suitable for bigger pots while smaller LECA works best in smaller containers. This will allow the roots to properly fill the space without becoming rootbound.
Monitor the moisture level of the LECA closely (LSI: moisture level). Check several inches below the surface to determine if the medium is dry before watering again. Alocasia roots in LECA need adequate moisture but cannot tolerate soggy, waterlogged conditions. Allowing the medium to dry out slightly in between waterings will help prevent overwatering.
Clean and sterilize LECA occasionally to remove any mineral buildup. This will help maintain proper pore space for optimum drainage and aeration over time. You can soak the LECA in a 10% bleach solution, then rinse thoroughly and allow to dry before reusing.
Consider pairing LECA with other pebbles or gravel in the container for alocasia (LSI: perlite, vermiculite). This can provide additional support, improve drainage and increase aeration in the root zone. Coarse gravel like pumice works particularly well mixed with LECA.
Apply fertilizer specifically formulated for hydroponic or soilless use. These types of fertilizers will be more concentrated for optimum uptake by plants in inorganic media like LECA. Follow the label instructions and adjust the dilution based on your alocasia plant’s needs.
Replace LECA once it begins to break down, around every 2-3 years. Over time the clay spheres will degrade, losing their porous structure and ability to properly drain and aerate. Signs your LECA needs replacing include poor drainage, reduced plant growth and deteriorating root health.
In summary, by choosing the right size LECA, monitoring moisture levels carefully, cleaning and replacing the medium as needed, and pairing it with other aggregates, you can give your alocasia the best chance at success when growing in LECA. In the final section, we’ll conclude by recapping the main benefits of LECA for alocasia plants.
