Monstera deliciosa has holes because it evolved to survive in the harsh, windy, and shadowy conditions of tropical rainforests.
Those iconic holes, known as fenestrations, are not a sign of damage or disease, but a clever survival adaptation that has fascinated plant lovers for generations.
If you’ve ever wondered why does monstera deliciosa have holes, the answer lies deep in its natural history, where light, rain, and wind all shaped its unique leaf structure.
In this post, we’ll explore the main reasons why monstera deliciosa has holes, how these holes help the plant thrive, and what it means for your own monstera’s growth.
Let’s dig into the science behind those stunning splits.
Why Does Monstera Deliciosa Have Holes? The Core Survival Strategy
The real reason why monstera deliciosa has holes is tied to its life on the rainforest floor.
As a young plant, the monstera crawls along the ground seeking a tree to climb, and this is where the holes begin to matter most.
When it finally climbs a tree, the leaves face direct sunlight, heavy rains, and strong winds, and the holes are a brilliant solution to all three challenges at once.
Let’s break down the specific ways this adaptation works.
1. Holes Help Monstera Catch More Sunlight
The primary reason why monstera deliciosa has holes is to capture light efficiently in the understory.
At the forest floor, sunlight is a precious resource, filtered through the dense canopy above.
If the monstera had solid, broad leaves, the lower leaves would be completely shaded by the ones on top.
By developing holes, the monstera allows sunlight to pass through the top leaves, so lower leaves can also photosynthesize.
This light transmission is crucial for the plant’s energy production, and it directly answers why does monstera deliciosa have holes.
The holes reduce leaf surface area, but they don’t reduce the plant’s ability to gather light overall, they just spread it more effectively.
So each leaf gets a fair share of light, no matter its position, and that’s a huge advantage in a dark jungle.
2. Holes Help the Leaf Survive Heavy Rain
Another major reason why monstera deliciosa has holes is to survive tropical downpours.
In its native rainforests, monsoon rains can dump massive amounts of water in a short time.
If the leaves were solid, water would pool heavily on the leaf surface, making the leaf heavy and brittle.
That extra weight could snap the leaf stem or damage the plant’s structure.
The holes allow water to pass right through the leaf, preventing water from accumulating.
This is why monstera deliciosa has holes that act like natural drainage pipes for the plant.
Rainwater slips through the fenestrations, keeping the leaf dry and stable, even during a violent storm.
This simple but effective design keeps the monstera intact while other forest plants struggle.
3. Holes Help the Plant Stand Strong in Wind
Wind is another silent force that shapes why monstera deliciosa has holes.
Tropical storms bring high winds that can shred or uproot plants with large, broad leaves.
The holes in monstera leaves reduce wind resistance, so the leaf doesn’t act like a giant sail.
Less wind resistance means less stress on the stem and roots, which is vital for a climbing plant.
When wind passes through the holes, it reduces the chance of tearing or snapping.
So the question of why does monstera deliciosa have holes gets a clear answer: it’s a windbreaker.
The holes keep the plant anchored and secure, allowing it to grow tall without being blown away.
This structural benefit is one of the reasons monstera deliciosa has holes in its mature leaves only.
Why Doesn’t My Monstera Have Holes Yet?
You might be asking why your monstera deliciosa has holes missing, despite your best care.
The truth is, young monstera plants often have solid, heart-shaped leaves without any fenestrations.
This is perfectly normal, as the holes appear only when the plant reaches maturity and begins climbing.
The holes are tied to the plant’s life stage, not just its overall age.
If your monstera doesn’t have holes, it likely hasn’t matured enough to develop them.
Here’s what you can do to encourage fenestrations, so you can finally see why monstera deliciosa has holes in action.
1. Give Your Monstera More Light
One reason why monstera deliciosa has holes in the wild is that it grows in brightly lit gaps in the canopy.
If you keep your monstera in a dim corner, it has no reason to develop holes since it doesn’t need to optimize light.
Place your plant near a bright, indirect light source, like an east-facing window.
Brighter light mimics the forest edge, signaling the plant to invest energy into leaf fenestration.
This is one of the most reliable ways to trigger hole formation in a mature monstera.
2. Give It a Moss Pole to Climb
In nature, the monstera grows upward because that’s when it starts producing holes.
If your monstera remains as a bush without vertical support, it may never develop fenestrations.
Add a moss pole or a trellis, and let your plant climb naturally.
The upward growth triggers the mature leaf structure, which is exactly why monstera deliciosa has holes.
Climbing also exposes the leaf to more light and airflow, reinforcing the survival strategy.
Once it starts climbing, you’ll likely see new leaves with splits and holes.
3. Be Patient with the Growth Process
Fenestrations don’t appear overnight, and there’s a timeline to why monstera deliciosa has holes.
Mature leaves can take months to develop, and each new leaf may have more holes than the last.
The plant develops holes gradually from the outer edges inward, starting with shallow splits.
Over time, those splits become deeper, and some leaves even develop full inner holes.
So if you’re not seeing holes yet, just give your monstera enough light, support, and time.
Soon enough, you’ll witness the exact reason why monstera deliciosa has holes.
Still Wondering Why Does Monstera Deliciosa Have Holes? Here’s a Quick Recap
The holes on a monstera deliciosa are not just decorative; they are a functional response to its environment.
Monstera deliciosa has holes to capture more sunlight, survive heavy rainfall, and withstand strong winds.
These holes, called fenestrations, allow the plant to grow tall and strong in the jungle canopy.
The plant develops holes as it matures, and you can encourage that growth with proper light and climbing support.
So if you’ve been wondering why does monstera deliciosa have holes, now you know it’s all about survival.
Next time you admire your monstera, you’ll see that every hole is a tiny story of resilience.
Take a moment to appreciate how this plant adapted to thrive in one of the toughest environments on Earth.
Your monstera with holes is not just beautiful, it’s a living testament to evolutionary brilliance.
And while you enjoy those fenestrations, remember that the holes are doing important work for your plant’s health.
So keep your monstera happy, and it will reward you with even more gorgeous holes over the years.
That’s the full story behind the holes, and it’s as fascinating as the plant itself.
