A monstera starts getting holes when it’s mature enough, typically between one and three years old or once it has at least five to seven leaves.
If you’ve been watching your plant grow and wondering when does a monstera start getting holes, the short answer is that it depends on light, age, and overall health.
Young monsteras grow solid, heart-shaped leaves without any splits or fenestrations, and that’s totally normal for a juvenile plant.
In this post, we’ll talk about when does a monstera start getting holes, why some leaves stay solid, and how you can encourage those beautiful splits to appear.
Let’s dig into the fascinating timeline of monstera leaf development.
When Does a Monstera Start Getting Holes: The Age Factor
Your monstera will start getting holes when it reaches a certain stage of maturity, and that stage is mostly tied to how old the plant is.
A monstera starts getting holes once it’s been growing for about two to three years under good conditions.
But this timeline can shift depending on whether your plant is a young cutting, a seedling, or a mature specimen.
1. Monsteras Need a Juvenile Phase First
Every monstera begins life as a juvenile, and juvenile leaves are completely solid with no holes at all.
Your monstera will start getting holes only after it transitions from this juvenile phase into a mature growth pattern.
This transition is triggered by the plant’s internal clock, not by how many leaves it has, although leaf count is a good visual clue.
Most indoor monsteras stay juvenile for the first year or two, so patience is key if you’re waiting for those first fenestrations.
2. Leaf Count Determines When Monsteras Start Getting Holes
The easiest way to know when does a monstera start getting holes is to count the leaves on your plant.
A monstera starts getting holes once it has around five to seven leaves that are roughly six inches wide or larger.
Leaves that are smaller than this are usually still juvenile, and they’ll stay solid until the plant gains enough energy to mature.
Once you see that sixth or seventh leaf unfurl, keep an eye on the next few new leaves because that’s when the magic usually happens.
3. Monstera Starts Getting Holes Faster in Bright Light
Light is one of the biggest factors in when your monstera starts getting holes, and bright indirect light speeds up the process.
In low light, monsteras grow slower and often hold onto their juvenile leaves for much longer.
Place your monstera near a bright window with filtered sunlight, and it’ll have the energy to produce mature leaves with holes.
You might notice that monstera starts getting holes more quickly in spring and summer when days are longer and light is stronger.
Pro tip: If you see your monstera leaning toward the window, that’s a sign it wants even more light.
Why Your Monstera Isn’t Getting Holes Yet
If your plant is older but still hasn’t developed holes, you might be asking when does a monstera start getting holes under less-than-ideal conditions.
It’s frustrating when your monstera starts getting holes slowly, but there are a few common reasons behind the delay.
1. Lack of Sunlight Slows Down Hole Formation
When does a monstera start getting holes if it’s stuck in a dark corner? Honestly, it might never happen.
Monsteras are tropical understory plants, but they still need bright, indirect light to photosynthesize enough for fenestrations.
Without adequate light, your monstera will focus on just surviving rather than producing fancy mature leaves.
Try moving it to a brighter spot, but avoid harsh direct sun which can scorch those beautiful green leaves.
2. Inconsistent Watering Stalls Monstera Growth
Your monstera starts getting holes only when it’s actively growing, and dry or soggy soil stops growth in its tracks.
Water your monstera when the top two inches of soil feel dry, and make sure the pot has drainage holes.
Overwatering can cause root rot, which prevents the plant from absorbing nutrients needed for leaf maturity.
Underwatering is just as bad because the plant will drop older leaves before it ever develops new ones with holes.
3. No Support Means No Mature Leaves
In the wild, monsteras climb up trees, and this vertical growth signals the plant to mature.
When does a monstera start getting holes if it’s just sprawled on the floor? Often, it stays juvenile because it thinks it’s still a ground vine.
Give your monstera a moss pole, trellis, or wooden stake, and encourage it to climb.
Once the aerial roots attach to that support, your monstera starts getting holes because it senses it’s reached a mature climbing stage.
How to Encourage Your Monstera to Start Getting Holes
Now that you know when does a monstera start getting holes, you can actively speed up the process with a few simple tricks.
It’s not just about waiting; you can create the perfect environment for fenestrations to appear sooner.
1. Fertilize to Boost Leaf Maturity
Use a balanced houseplant fertilizer with equal parts nitrogen, phosphorus, and potassium every four to six weeks during the growing season.
Nitrogen encourages lush leaf growth, which is exactly what your monstera needs to push out larger, mature leaves.
Just don’t over-fertilize, because too much salt buildup can burn roots and actually delay when your monstera starts getting holes.
2. Prune Old Juvenile Leaves Strategically
You can trick your monstera into maturing faster by trimming away a few of the oldest, smallest juvenile leaves.
When you remove those solid leaves, the plant redirects its energy toward newer growth, which is more likely to have holes.
Only prune a few leaves at a time, and make sure you’re cutting just above a node so new growth can emerge.
This doesn’t change the fundamental age requirement, but it does help your monstera start getting holes a bit sooner.
3. Keep Humidity Levels High
Monsteras love humidity, and higher humidity encourages faster, healthier leaf development.
Aim for humidity levels between 60% and 80% using a humidifier, pebble tray, or by misting regularly.
In dry indoor air, leaves can come out smaller and with fewer splits, so you might wonder when does a monstera start getting holes at all.
Keeping your plant in a bathroom or kitchen, which naturally have more moisture, can work wonders.
So, When Does a Monstera Start Getting Holes? Final Answer
A monstera starts getting holes when it matures, but you can think of it as a mix of age, light, and support.
For most indoor plants, a monstera starts getting holes around the two-year mark with bright indirect light and a climbing structure.
Juvenile leaves without holes are perfectly normal for the first year, so don’t panic if your plant looks plain.
What matters most is giving your monstera consistent care, plenty of indirect sunlight, and a moss pole to climb.
When does a monstera start getting holes? It starts when it’s ready, and your job is to create those conditions as best you can.
Keep watering on a schedule, fertilize during spring and summer, and move your plant to a brighter window if needed.
With a little patience and the right environment, you’ll see those first stunning holes appear before you know it.
Happy growing, and enjoy watching your monstera transform from a simple juvenile into a fenestrated beauty.
