A Monstera gets holes when it matures and receives the right conditions to develop them.
Those iconic splits and holes, known as fenestrations, don’t show up on baby plants.
If you’ve been wondering when does a monstera get holes, the short answer is that it starts happening once the plant is a few years old and has enough light.
The timing isn’t exact, but most indoor monsteras begin to develop their first holes and slits when they’re around two to three years old.
In this post, we’ll dive into why a monstera gets holes, the factors that speed up or delay the process, and what you can do to encourage those beautiful fenestrations.
Let’s help your monstera reach its full, holey potential.
Why A Monstera Gets Holes In The First Place
The reason a monstera gets holes isn’t just for looks, it’s actually a survival adaptation from its natural jungle habitat.
In the wild, monsteras grow up the trunks of large trees, spreading their leaves out to catch dappled sunlight.
The holes and slits allow sunlight to pass through the upper leaves and reach the lower ones on the same stem.
They also reduce wind resistance, which means heavy tropical storms are less likely to tear the large leaves apart.
So when you ask when does a monstera get holes, you’re really asking when it starts acting like the mature, jungle-adapted plant it’s meant to be.
1. Age Is The Biggest Factor
A monstera gets holes as it matures, and age plays the most significant role in this process.
A young monstera, especially one grown from a cutting or seed, will have solid, heart-shaped leaves without any splits.
These juvenile leaves are designed to maximize surface area for photosynthesis while the plant is still small and close to the ground.
As the plant grows upward and gains more structural support, it transitions into its adult phase.
This is when a monstera gets holes, typically after it has produced around five to seven leaves from a single stem.
Once that transition begins, each new leaf will generally have more fenestrations than the last one.
2. Light Levels Control The Timeline
Your monstera gets holes when it’s receiving bright, indirect light, not just when it’s old enough.
Light is the primary trigger for fenestration development because it tells the plant it’s in an optimal environment for maturity.
If your monstera sits in a dim corner, it may stay in its juvenile form for many years without producing a single hole.
Think of fenestrations as a sign that your plant is thriving, not just surviving.
A monstera that gets plenty of bright, filtered sunlight will start to get holes much sooner than one stuck in low light.
If you want your monstera to get holes faster, move it closer to a window with sheer curtains or an east-facing exposure.
3. Pot Size And Roots Matter
A monstera gets holes when its roots have room to spread out and establish a strong foundation.
If your plant is root-bound in a tiny pot, it might stop producing new leaves altogether, which delays fenestration development.
On the flip side, an oversized pot can lead to waterlogged soil and root rot, which also halts growth.
The sweet spot is a container that’s only about two inches larger in diameter than the root ball.
A healthy root system allows the plant to channel energy into producing larger, more mature leaves.
And larger leaves are exactly when a monstera gets holes, so don’t neglect this factor.
How To Speed Up When Your Monstera Gets Holes
If you’re impatient for your monstera to get holes, there are a few practical steps you can take to nudge it along.
These methods won’t guarantee instant fenestrations, but they’ll create the ideal conditions for them to appear.
Monsteras are forgiving plants, but they respond best when you mimic their natural environment as closely as possible.
1. Provide A Moss Pole Or Trellis
A monstera gets holes more readily when it can climb, just like it does in the wild.
In nature, these plants are epiphytes, meaning they grow on other plants rather than in soil.
By giving your monstera a moss pole or wooden trellis to cling to, you’re encouraging vertical growth.
This vertical growth signals the plant to produce adult leaves with fenestrations.
Simply tie the stem loosely to the pole with soft plant ties, and keep the moss slightly damp.
As the aerial roots latch onto the support, your monstera will start to get holes much sooner than if it’s left to sprawl.
2. Offer Consistent, Balanced Fertilizer
Your monstera gets holes when it has enough nutrients to support the energy-intensive process of producing mature leaves.
During the growing season (spring and summer), feed your monstera a balanced liquid fertilizer every four to six weeks.
Look for a formula with equal parts nitrogen, phosphorus, and potassium, like a 10-10-10 mix.
Nitrogen supports leafy growth, phosphorus encourages root health, and potassium boosts overall vigor.
Don’t overdo it though, as too much fertilizer can burn the roots and set back fenestration development.
A monstera that’s well-fed but not overfed will get holes on a steady timeline.
3. Be Patient With Humidity And Watering
Humidity plays a supporting role in when a monstera gets holes, though it’s not as critical as light or age.
Monsteras prefer humidity levels around 60% or higher, which you can achieve with a humidifier or a pebble tray.
Higher humidity helps leaves expand fully without the edges browning or crisping.
Watering is equally important, so wait until the top two inches of soil are dry before giving your plant a good drink.
Overwatering is a common mistake that leads to yellow leaves and stunted growth.
A healthy monstera will get holes when it’s neither parched nor drowning.
Common Mistakes That Delay Fenestrations
Knowing when a monstera gets holes is just half the battle; avoiding these pitfalls is the other half.
Many plant parents accidentally slow down the fenestration process without realizing it.
Here are the most common culprits and how to fix them.
1. Too Much Direct Sunlight
While bright light is essential, direct afternoon sun can scorch monstera leaves.
Burned leaves can’t photosynthesize effectively, which means less energy for new, mature growth.
If your monstera sits in harsh sunlight, its leaves may develop brown patches instead of holes.
You’ll know a monstera gets holes under the right light when the leaves stay green and glossy.
Move your plant a few feet back from a south-facing window or use a sheer curtain to filter the rays.
2. Pruning Away The Wrong Leaves
If you prune your monstera too aggressively, you might remove the very leaves that are about to develop holes.
The oldest leaves at the bottom often have the most fenestrations, though they may look less vibrant over time.
Don’t cut these lower leaves unless they’re yellowing or damaged.
Instead, focus on removing only dead or diseased foliage.
Every leaf you keep gives your monstera more energy to dedicate to new growth that gets holes.
3. Inconsistent Care Routines
Monsteras are not fans of sudden changes in their environment.
Moving the plant to a different room, changing its watering schedule drastically, or repotting at the wrong time can all stress it out.
Stress often causes a monstera to stop growing and hold onto its juvenile leaves.
A stable routine is what makes a monstera get holes on schedule.
Keep the temperature between 65°F and 85°F and avoid cold drafts.
If you treat your monstera with consistent care, fenestrations will follow naturally.
So, When Does A Monstera Get Holes?
A monstera gets holes when it reaches maturity, typically between two and three years of age, and when it receives the right combination of light, support, and nutrients.
There’s no exact calendar date, but the process is entirely predictable once you understand the plant’s needs.
If your monstera is still producing solid leaves, don’t panic, it’s simply not ready yet.
Give it time, increase its light exposure gradually, and provide a climbing structure.
Before you know it, the next new leaf will unfurl with that first beautiful slit, and soon after, a monstera gets holes all over its foliage.
The wait is always worth it when you see those stunning, architectural fenestrations.
Happy growing, and here’s to your monstera reaching its full, holey glory.
