In the world of indoor tropical plants, Alocasia reigns supreme. From the table-top friendly Alocasia Polly to the aggressively striped Alocasia Zebrina, you probably have at least of these Araceae family members in your collection– but have you ever considered growing your Alocasia in LECA?

If you don’t know, Lightweight Expanded Clay Aggregate (LECA) is a soilless growing medium made up of lightweight and porous clay balls. LECA clay pebbles are increasingly popular for growing growing plants semi hydroponics setups. You can grow many popular houseplant with it, and it can provide many benefits to Araceae plants, like Monstera and Alocasia, specifically.

In this article, we’ll guide you through the process of growing Alocasia in LECA, from converting your soil-based Alocasia to LECA to using hydroponic fertilizer to help your plants thrive.

Benefits of Alocasia in Leca

Transitioning your Alocasia plant to LECA can be a great way to improve drainage, aeration, and reduce the risk of overwatering. The plant roots of Alocasia can be quite thick, with many smaller root hairs coming off of larger roots. This makes Alocasia a prime candidate for one of your first transitions to LECA. Using LECA as a substrate can also make cleaning your Alocasia roots more enjoyable.

If you’re looking for a way to grow your Alocasia plants in a low-maintenance, efficient, and effective way, then using LECA might be the perfect solution for you. Here are some of the benefits this trendy growing medium for your Alocasia:

• Excellent drainage: Alocasia plants are prone to root rot, and using LECA as a growing medium can help prevent this issue. The porous clay spheres increase aeration in the root zone, ensuring that water doesn’t accumulate around the roots and cause problems.
• Improved aeration: Alocasia plants need good airflow to promote root growth, and LECA can provide this. The large pore space in the LECA balls allows for good oxygen diffusion to the roots, promoting healthy growth and development.
• Better hydration: While LECA balls provide excellent drainage and aeration, it also retains enough moisture for proper hydration. It reduces the need for frequent watering while still providing the consistent moisture that tropical plants like Alocasia plants need to thrive.
• Reduced soil-borne diseases: Alocasia plants are susceptible to soil-borne diseases, which can be difficult to manage. Using clean LECA as a growing medium can help reduce the risk of these diseases, as the clay spheres are sterile and free of pathogens.
• Efficient use of water and fertilizer: LECA can help you save water and fertilizer, as it allows you to water less frequently and use less fertilizer overall. This is because the clay spheres retain moisture and nutrients, releasing them slowly over time as the plant needs them.

Overall, using LECA as a growing medium for your indoor plants can provide numerous benefits. It can help prevent root rot, improve aeration and hydration, reduce the risk of soil-borne diseases, and even help you save water and fertilizer. If you’re looking for an efficient and effective way to grow your Alocasia plants, then using LECA might be the perfect solution for you.

Complications of Using LECA to Grow Tropical Plants

Using LECA can be a great way to provide your Alocasia plant with the right amount of moisture and oxygen. However, there are some complications with plants grown in clay pebbles. Here are some of the most common issues that you may encounter with Alocasia planted in LECA:

1. Root Rot

Root rot is a common problem with soil-planted Alocasia when not using a well draining soil. But it’s also a problem you might face when growing in LECA. This is because the roots of Alocasia are very sensitive to moisture. If your plant’s roots are constantly exposed to water, they can start to rot.

2. Nutrient Deficiencies

Another complication is nutrient deficiencies. Because Leca is an inert growing medium, it does not provide any nutrients to your plant. This means that you will need to provide your plant with a hydroponic nutrient solution to ensure that it is getting all of the nutrients that it needs.

3. pH Imbalance

Leca can also affect the pH balance of your soil. Because Leca is alkaline, it can raise the pH of your soil over time. This can cause nutrient deficiencies and other problems for your plant.

To avoid pH imbalances, make sure that you are using the right type of Leca and that you are monitoring the pH of your soil regularly. You may need to adjust the pH of your soil using a pH adjuster or other soil amendments.

4. Transplant Shock

Finally, when you are transplanting your Alocasia into Leca, you may experience some transplant shock. This is because your plant is accustomed to grow roots in soil. Eventually, your plant will grow new water roots that are much more efficient at absorbing nutrients directly from the water.

To minimize transplant shock, make sure that you are transplanting your Alocasia when it is not actively growing. You should also make sure that you are not disturbing the roots too much when you are transplanting your plant.

Overall, growing Alocasia in Leca can be a great way to provide your plant with the right amount of moisture and oxygen. However, there are some complications that you need to be aware of. By understanding these issues and taking the necessary precautions, you can help ensure that your Alocasia thrives in its new growing medium.

Helping Alocasia Plants Thrive in LECA

If you’re looking for a low-maintenance way to grow your Alocasia plant, clay balls might be the way to go. Here’s how to do it.

Preparing the Leca

Before you start planting your Alocasia in Leca, you need to prepare the LECA first. Rinse it under running water to remove all the clay dust. And then soak the LECA for up to 24 hours before using, letting the little air pockets absorb the water your plants will need.

Planting Alocasia in LECA

Now that your Leca is ready, it’s time to plant your Alocasia. Start by removing the plant from its old pot and gently shaking off any excess soil from the roots. Then, add a base layer of clay pebbles at the bottom of the pot. Place the Alocasia on top and add more LECA balls around the roots until the pot is full.

Watering Plants and Hydroponics Fertilizer

When watering your Alocasia in Leca, make sure to pour water into the pot until it reaches the bottom of the LECA layer. This will help the plant absorb the water it needs without overwatering. You must also add hydroponics fertilizer to the water to provide nutrients as the plant grows. During the summer growing season, you may need to water and fertilize more frequently.

Caring for Alocasia in LECA

To care for your LECA-planted Alocasia, make sure it gets enough light and humidity. You can place the pot on a pebble tray filled with water to increase humidity, or use a humidifier. Keep the temperature between 60-85°F. Be sure to change the water every week or so and keep an eye out for signs of root rot.

LECA Cleaning Process

You should flush your clay pebbles with running water at least once a month to avoid excess mineral build-up within the pot. Because you’ll be adding nutrient solution each time you water, the unused minerals can attach to the clay balls, which can reduce their ability to function at their best.

Some popular Alocasia species to include Alocasia Zebrina, Alocasia Silver Dragon, and Alocasia Polly. You can buy LECA at almost any plant supplier or nursery. Remember to avoid overwatering or letting excess water sit in the pot. With proper care, your Alocasia in Leca will thrive and show off its beautiful veins.

Frequently Asked Questions:

What Types of Pots Are Suitable for Growing Alocasia in LECA?

When growing Alocasia in LECA, we’d recommend using use clear containers that allow you to monitor the water level and root health. If your pot has drainage holes, you’ll need to put another pot underneath it to create a reservoir of water. The LECA balls will pull the water up to the plant’s root zone using the capillary effect.

What Common Pests or Diseases Affect Alocasia in LECA?

The good news is that LECA helps to limit pest infestations (because there’s no organic material for them to live in). But that’s not to say they’re not possible. Pests like spider mites, fungus gnats, and aphids can attack your Alocasia even when growing in LECA. Inspect them regularly and use an insecticidal soap or neem oil, if necessary. If an indoor plant disease appears, consult with a plant care specialist.

How Long Is The Transition Period When Transplanting from Soil to LECA?

Transitioning Alocasia from soil to LECA may cause temporary stress to the plant, but the exact timeframe will depend on the individual plant. It’s advised to transplant during a period of non-active growth and gradually transition to the LECA environment to minimize shock. Within a month or two, it should acclimate. And by 3-6 months it should be growing as fast, or faster, than ever.

Can Alocasia in LECA Be Kept Outside? What Are the Considerations?

Alocasia can be grown in LECA outdoors in warmer climates, but you’ll need to consider factors like weather conditions, humidity, temperature, and sunlight. This is a tropical plant accustomed to living under a canopy of larger plants, so it doesn’t want direct sunlight and needs plenty of moisture. And moving it outside for summer and inside for winter could cause significant stress.

How Do I Prune and Propagate Alocasia in LECA?

Pruning dead or yellowing leaves is similar to standard Alocasia care but requires careful handling of the LECA medium. Propagation can be done by division, placing the new section in LECA and following these care guidelines for watering and nutrients:

1. Identify and Prepare the Section for Propagation: Inspect your Alocasia and choose a healthy section with at least one or two leaves and roots attached. Clean any soil off the roots, ensuring they are in good condition.
2. Prepare the LECA: Rinse the LECA under running water to remove dust, and soak it for up to 24 hours, allowing the clay balls to absorb water.
3. Divide the Plant: Using a sharp, sterile knife or scissors, cut the identified section away from the parent plant, ensuring you include some roots in the division, or a growth node if cutting from the stem.
4. Plant in LECA: Place a layer of the prepared LECA at the bottom of a suitable pot. Position the divided Alocasia section on top, and gently add more LECA around the roots until the pot is full.
5. Care and Maintenance: Water the newly planted Alocasia in LECA, making sure to reach the bottom of the LECA layer. Regular monitoring of water levels, light, and nutrients is essential during the early stages of propagation to ensure the new plant establishes well. Add hydroponic fertilizer to the water once new roots start to form.
