Want to grow an XL size Monstera? You can coax those iconic leaves into reaching their full, dramatic size with these tips!
Monstera is known for its bold, fenestrated foliage, but getting those oversized leaves isn’t just about keeping the plant alive. It’s about guiding it the way it would grow in the wild. Here are a few thoughtful adjustments that can completely shift its growth pattern!
Want to Grow XL Monstera? Try These Tips
1. Give It a Moss Pole or Vertical Support
In its natural habitat, a Monstera doesn’t grow downward or outward. It climbs! And once it starts climbing, you’ll notice leaves becoming broader, thicker, and far more deeply split.
When left unsupported, your Monstera tends to sprawl and stay juvenile. That creeping habit limits leaf size because the plant isn’t receiving the structural cues it needs to “level up.” Adding a moss pole, a coco coir pole, or even a simple wooden plank gives it that vertical pathway. Here are more ideas you can try!
What to do? As aerial roots emerge, gently tuck them into the moist moss or tie the stems loosely with soft plant ties. Also, keep the pole slightly damp. Doing so mimics a tree trunk in a rainforest and encourages the roots to grip.
2. Upgrade the Pot Size Gradually
When roots circle tightly around the pot, growth slows because the plant can’t take up enough water or nutrients. Just repot your Monstera every 2 years, moving up to the next bigger size in diameter. This steady progression allows the root system to expand without overwhelming it.
Use a chunky, well-aerated mix; something with coco peat, bark, and perlite works beautifully to mimic the loose forest floor it prefers.
Why this works: An expansive root system means better nutrient uptake, which directly fuels leaf size and stem thickness. Healthy roots, in many ways, equal bold foliage above.
Just be careful not to jump into an oversized pot. Excess soil retains moisture longer, which can suffocate roots and invite rot, which is something Monstera are particularly sensitive to. You can check out this 12-inch ceramic pot with a drainage hole and a saucer that is perfect for indoors.
3. Increase Bright Indirect Light
For any plant, light is the engine behind leaf size. And if your Monstera isn’t getting enough, it will conserve energy by producing smaller, less fenestrated leaves.
The best thing you can do to grow XL Monstera is to place it near a bright window with filtered light. East-facing is ideal for gentle morning sun, and south-facing works well with a sheer curtain to diffuse intensity. The goal is bright, consistent light without harsh direct exposure that can scorch the leaves.
Pro Tip: Rotate the pot every couple of weeks; it will keep the plant from leaning and ensure even growth on all sides, giving you a fuller, more balanced specimen.
4. Feed the Plant During Active Growth
Monstera are surprisingly hungry plants when they’re in their active phase. In the wild, they feed continuously from organic matter breaking down around tree roots. Indoors, you need to recreate that steady nutrient supply.
It’s pretty easy to do. During spring and summer, apply a balanced liquid fertilizer every 3–4 weeks at half strength. Such a gentle, consistent feeding schedule supports sustained growth without overwhelming the roots.
Pro Tip: If you prefer a more natural route, occasional top-dressing with compost or vermicompost can also enrich the soil over time and improve microbial activity. And if you want deeper green Monstera leaves and faster expansion, apply Epsom salt and pick a fertilizer slightly higher in nitrogen during the growing season.
5. Maintain High Humidity
As you know, Monstera is a tropical plant, and these plants thrive in humid air. Higher humidity will help leaves expand fully and prevent the edges from drying out during development. Just aim for 60% humidity or higher around the plant.
You can achieve this by using a humidifier, grouping plants together, or placing a pebble tray with water under the pot. The moist air will keep leaf tissue flexible as it grows, while allowing leaves to stretch and develop large fenestrations.
Pro Tip: Bathrooms with bright windows often produce massive Monsteras because humidity levels naturally stay high.
6. Soak and Dry Watering to Grow XL Monstera
Monstera grow large when they receive consistent hydration, but constantly soggy soil can cause root rot. That’s because watering isn’t about frequency but rhythm. Monstera prefers a soak-and-dry cycle that mimics tropical rain patterns.
You should water your plant thoroughly until the excess drains from the bottom, ensuring the entire root ball is hydrated. Then allow the top 2 inches of soil to dry before watering again. It prevents roots from sitting in constant moisture, which can lead to rot.
Deep watering encourages roots to grow downward in search of moisture, creating a more extensive and resilient root system.
Pro Tip: Don’t forget to empty the drainage tray, as standing water is one of the quickest ways to compromise root health.
7. Let Aerial Roots Grow
Those long, wiry aerial roots might look untidy, but they are an essential part of how Monstera grow in nature. They act as anchors and secondary channels for moisture and nutrients.
Instead of trimming them off, guide them into the soil or your moss pole. Once they make contact, they begin functioning like additional roots, strengthening the plant’s support system. Remember, the more access your plant has to water and nutrients, the more resources it can allocate to producing large, healthy leaves.
Why this works: Aerial roots act as additional feeding channels, giving the plant extra resources to grow larger. Why don’t you try putting them in water?
8. Prune Strategically to Encourage Growth
When you remove weak, leggy, or damaged growth, the plant reallocates its resources toward stronger stems and larger leaves. Here’s what to do!
- Cut right above a node, where new growth naturally emerges. It encourages branching and can lead to fuller, more vigorous development over time.
- Always use sharp, sterilized shears. Clean cuts heal faster and minimize stress on the plant.
Pruning might sound counterintuitive when you want a bigger plant, but selective pruning this way actually redirects energy to stronger stems and larger leaves. And you’ll grow an XL Monstera.
Here is a good quality pair of pruning shears that can be a perfect option for you!
Growing an XL Monstera is all about mimicking its natural jungle environment and encouraging upward growth. With the right care, your Monstera can go from a simple houseplant to a massive tropical centerpiece.
