With its large, sprawling, hole-filled leaves, the Monstera plant is the quintessential houseplant of our time. You see Monsteras everywhere, not just because of their captivating looks. It’s also because they are particularly easy to grow– especially if you plant your Monstera in LECA.
LECA, if you’re unfamiliar with it, is an acronym for Lightweight Expanded Clay Aggregate. It’s those little, porous clay balls that you’ve probably seen everywhere, from your dentist’s office to IKEA. And LECA is a popular alternative to potting soil as a growing medium for houseplants like the Monstera deliciosa and other Monstera varieties.
In this guide, I’ll guide you through the nuances of nurturing your Monstera in LECA. Whether you’ve cared for countless plants or are just starting your plant parenting journey, the Monstera is an excellent choice for you. And I’m here to help you ensure your Monstera thrives.
Can You Grow Monstera Plants in LECA?
You can absolutely grow Monsteras in LECA. In fact, caring for many Monstera varieties in LECA, especially the popular Monstera deliciosa, may be easier than growing them in soil. Growing in LECA allows for natural root aeration, easy water regulation, and precise nutrient control, making it an easy solution for both experienced plant owners and first-time plant parents.
Why Choose LECA for Your Monstera?
If you already have a healthy Monstera in your home, you might wonder, “Is it worth switching to LECA?” Only you can make that call, but when it comes to growing Monstera, there are a few compelling reasons to consider this soilless growing medium:
Aeration: Monsteras love well-draining soil because their roots need ample oxygen. The nature of LECA growing means that many of your plant’s roots will never be submerged in water. Instead, they’ll absorb both water and oxygen simultaneously.
Plus, LECA balls are highly porous and hold both water and oxygen, allowing even submerged roots to breathe easily. This helps prevents root rot, a common issue many Monstera owners face when using traditional soil.
Water Regulation: Ever accidentally over-watered a plant? We’ve all been there. LECA reduces the chances of this blunder. The clay balls hold onto moisture but allow excess water to drain. This ensures your Monstera gets hydration without the risk of standing in water.
Nutrient Control: With LECA, you have 100% control over the nutrient mix your plant receives. You can tailor the nutrients to your Monstera’s individual needs. No more guesswork on whether your soil is too rich or lacking vital components.
Pest Reduction: Soil can sometimes introduce pests to your indoor plants. With LECA, the chances of bringing in unwanted guests like fungus gnats or mealybugs are reduced because they struggle to survive in an inorganic growth medium.
The benefits of semi-hydro growing with LECA can be a game-changer for your Monstera’s health and growth. And remember, every new venture with plants is a learning experience. Who knows? You might find LECA to be your new favorite way to grow plants!
How To Move Your Monstera from Soil to LECA
Moving to LECA might sound intimidating, but with some guidance, you’ll get the hang of it. Here’s a step-by-step breakdown to guide you through the process:
- Prep the LECA Balls: Before anything else, you’ll want to prepare your LECA by rinsing the clay balls thoroughly under running water. This helps to remove any dust or debris. After rinsing the balls, soak them in water for at least 4 hours or, ideally, overnight. This ensures they’re saturated and ready to provide moisture to your Monstera’s roots.
- Gently Remove Your Monstera from its Pot: It’s time to get your hands a bit dirty. Ease your Monstera out of its current container, careful not to damage the roots.
- Carefully Clean the Roots: You’ll need to remove as much soil as possible from the roots. Gently shake off the loose soil and use lukewarm water to rinse away the rest. This is crucial because residual soil can introduce harmful fungi or bacteria into the sterile hydroponic growing environment.
- Trim Any Damaged Roots: If you spot any roots that are black, mushy, or emit a foul smell, it’s a sign of root rot. Use sterilized scissors to trim away these damaged parts. Healthy roots should look firm and have a whitish or tan color.
- Plant Your Monstera in LECA: Choose a pot with ample drainage holes. Place a layer of LECA balls at the bottom. Position your Monstera in the pot and fill in around the roots with more LECA, ensuring the roots are well-supported and the plant stands upright.
- Add Water: Once your Monstera is snug in its new LECA home, water it immediately using a pH of 6.0-7.0 and a hydroponic fertilizer. The water level should sit just below the plant’s roots. This allows the roots to get oxygen while the capillary action draws water upwards to hydrate them.
- Observe and Adjust: The initial transition can be a shock for some plants. Monitor your Monstera closely for the next couple of weeks. If you notice any drooping or yellowing leaves, it might require some adjustments in your care routine.
PRO TIP: Planting your Monstera in a transparent or semi-transparent pot will make monitoring the water levels much easier. This is especially helpful if it’s your first time growing plants in LECA and you want to keep a close eye on everything.
And there you have it! You’ve given your Monstera a fresh new start in LECA! As you adjust to this change, remember that patience is vital. Like any new environment, it may take a little time for your plant to settle in and start thriving.
Caring for Your Monstera in LECA
Growing a Monstera in LECA is relatively easy. But you will still have to get familiar with the care routine to ensure your plant grows happy and healthy.
Take these steps to help your Monstera thrive and flourish:
General Care Guidelines
Flush Your LECA
Over time, nutrient salts can build up on LECA balls. It’s essential to flush your LECA them periodically to avoid this. Once a month, give your clay balls a thorough rinse under running water. This will not only refresh the growth medium but also benefit the overall health of your Monstera and help prevent root rot.
Watch Out For Algae
Algae can sometimes develop in LECA, especially if exposed to light and moisture. While a little algae isn’t a massive concern, excessive growth can block airflow to the roots. If you notice too much green build-up, consider moving your plant to a location with less direct sunlight or using an opaque container.
Read Your Roots
The roots of your Monstera tell you a lot about how well it’s doing. Healthy roots are firm and light-colored. If you notice them turning brown or getting mushy, it could be a sign of overwatering or root rot. LECA reduces the chances of root rot, but it doesn’t eliminate the possibility. So ensure the LECA doesn’t stay overly saturated, and always allow for proper aeration.
Feeding & Watering Tips
Keep Roots Moist
Don’t think Monstera needs less water because it is in LECA. LECA provides excellent drainage, but your Monstera still needs consistent moisture. Make it a routine to check the water levels in your reservoir and water your plants in LECA regularly, ensuring the planter doesn’t run dry. Remember, the roots should not be entirely submerged, but they should always have access to water.
Fertilize Regularly
Monstera plants in LECA get all of their nutrients from the water. So be sure to use a hydroponic nutrient solution tailored to houseplants whenever you add water! The ratio of nutrients is vital – too much can burn the roots, while too little can starve your plant.

Monitor pH Levels:
The pH level of your water plays a crucial role in nutrient absorption. Monstera plants prefer a slightly acidic environment, with pH values ranging between 6.0 to 7. It’s a good idea to test the pH of your water every so often, especially if you’re using tap water or adding nutrients. Adjusting pH levels can be done using pH up or down solutions, available at most garden centers.
Light & Temperature Guidelines
Find The Right Light
Monsteras prefer bright, indirect light. Placing them near an east or north-facing window is ideal. If you’re using artificial lighting, fluorescent or LED grow lights can be beneficial. Make sure to avoid direct sunlight, as this can scorch the leaves.
Rotate & Adjust
If you notice your Monstera’s leaves growing away from the light or becoming leggy, it might be time to adjust its light source. Rotating the plant every few weeks ensures even growth.
Keep It Cozy
Monstera plants enjoy temperatures between 65°F and 75°F (18°C – 24°C). Ensure the environment doesn’t get too cold, as these tropical plants can be sensitive to sudden temperature drops. Also, avoid placing them near radiators, heaters, or drafty windows.
Now you’re all set to nurture your Monstera in LECA with confidence. Regularly monitoring and adjusting based on your plant’s needs will ensure it remains a statement piece in your home for years to come.
Monstera Pruning & Propagation
Why Pruning is Essential
Keeping your Monstera looking its best is about more than just what you feed it and where you put it. Periodic pruning can do wonders.
Pruning isn’t just about aesthetics; it’s about plant health. Removing yellow or damaged leaves gives your plant a new lease on life, redirecting its energy to newer, healthier growth. Besides, your Monstera will send you silent thank-yous in the form of fresh, vibrant leaves!
Steps to Prune Your Monstera:
- Get the Right Tools: A pair of clean, sharp pruning shears or scissors is all you need. Ensure they’re sterilized to avoid introducing pathogens.
- Identify the Right Spots: Look for yellowing leaves, damaged sections, or areas where the plant is too dense.
- Make Clean Cuts: Always cut at the base of the stem, right next to the main stalk. This ensures the plant heals faster and avoids unnecessary stress.
- Don’t Overdo It: It’s tempting to give your Monstera a significant trim but remember, every leaf is a powerhouse of photosynthesis. Prune sparingly.
Propagation: Growing Little Monsters
You’ve seen it before: a friend proudly displaying a new plant that’s a “baby” of their original one. That’s the magic of propagation, and guess what? You can do it, too, especially with Monstera, which propagates quite easily.
Steps to Propagate Your Monstera in LECA:
- Choose a Healthy Stem: Look for a healthy stem with a few leaves and, ideally, an aerial root or two. Your sweet spot is the section right below a leaf node (where the leaf connects to the stem). Try to aim for a cutting that’s about 6″ long, if possible.
- Make a Clean Cut: Using your sterilized shears, make a cut a couple of inches below the node. Make sure it’s a clean cut that’s diagonal (not straight across) to provide more surface area to absorb water and grow roots.
- Rooting Time: Place the cut stem in a container of fresh water. Add a rooting hormone if you choose. Change the water every few days to keep it from stagnating, and in a few weeks, you should notice roots starting to grow.
- Transition to LECA: Once the roots are a few inches long, it’s time to move your baby Monstera to LECA. Gently introduce it to the LECA balls, ensuring the roots are well-supported.
Remember, patience is your best friend during propagation. Watching a new plant come to life from a mere cutting is exciting– it feels a bit magical! Remember, you’re not just growing plants; you’re growing memories. Every propagated plant carries stories of its parent plant and all the love and care you’ve given to it.
Common Challenges & Solutions When Growing Monstera in LECA
Leaf Yellowing
Why it Happens: Overwatering is often the culprit behind yellowing leaves. In a LECA setup, this can arise if you need to allow more time for the roots to access oxygen between waterings.
What to Do: Ensure you’re following the watering guidelines discussed earlier. Remember, it’s essential to let your Monstera’s roots breathe. Adjust your watering schedule and monitor the plant’s response.
If you’re pretty sure it’s not being overwatered, it’s possible it’s under-watered instead. Unfortunately, the symptoms are similar. If this is the case, water it immediately and ensure you don’t wait for your reservoir to dry before adding more water.
Brown or Crispy Leaf Edges
Why it Happens: This often indicates a lack of humidity or excessive fertilization. Monstera plants are native to tropical rainforests and thrive in humid conditions.
What to Do: You can increase humidity by placing a humidifier near your plant, setting the pot on a tray filled with water and pebbles (ensuring the pot doesn’t sit directly in the water), or misting the leaves regularly. If over-fertilization is suspected, ensure you use the recommended amount and consider rinsing the roots to remove excess nutrients.
PRO TIP: Try measuring your water’s electrical conductivity (EC) levels to see if you’re being heavy-handed with your fertilizer.
Stunted Growth or Pale Leaves
Why it Happens: These signs usually indicate inadequate light or nutrient deficiencies.
What to Do: Ensure your Monstera is receiving adequate indirect light. Too much direct sunlight can cause sunburn, but little light can hinder growth. If you suspect a nutrient deficiency, review your fertilization regimen. Are you providing all essential nutrients in the right amounts?
Root Rot
Why it Happens: Persistent overwatering in a LECA system can still lead to root rot, as the roots remain submerged for too long without access to air.
What to Do: If you notice your Monstera’s roots turning brown or mushy, it might be time for an intervention. Remove the plant from the LECA, trim away any rotten roots, and allow it to dry out for a couple of days before reintroducing it to the LECA medium. Ensure that none of your roots extend into the reservoir zone when you replant, and revise your watering schedule as necessary.
Pests
Why it Happens: Even with the best care and a sterile growing medium, pests like spider mites, mealybugs, or aphids might find your Monstera.
What to Do: Keep an eye out for signs of these pests, like webbing, white cottony substances, or tiny bugs on the undersides of leaves. If you find them, isolate the affected plant, and treat it with insecticidal soap or neem oil. Regularly inspecting your plant and keeping it clean can help prevent infestations.
Every plant parent faces challenges now and then. Your dedication and willingness to learn, adjust, and keep going are what sets you apart. Remember, every hiccup is a learning opportunity. And with every challenge overcome, your bond with your Monstera deepens.
FAQs about Monstera Plants in LECA
Can I transfer my Monstera from soil to LECA?
Yes, you can. However, it’s vital to ensure that all soil is gently removed from the roots and that the roots are in good health before making the switch. Introduce your plant to the LECA environment gradually to reduce transplant shock.
Do I need to repot my Monstera as it grows in LECA?
Yes, as your Monstera grows, its root system will expand. You should move it to a larger container to accommodate this growth and provide stability. Otherwise, your roots will circle and crowd the container, eventually absorbing less nutrients and increasing the chances of deadly root rot.
Can I propagate Monstera cuttings in LECA?
Absolutely! LECA can be an excellent medium for propagation. Ensure the cutting has a few healthy roots or nodes and follow the usual propagation process.
How deep should the water reservoir be for a Monstera in LECA?
