Monstera’s leafy windows are one of the unique features that ensure this plant is suitable for the indoor climate. It is also a characteristic that differentiates this tropical plant from others.
But there are cases when monstera leaves slow down or do not fenestrate at all. There is no need to panic as the problem can be easily fixed.
So why aren’t my monstera leaves splitting? Possible causes include young age, low light, nutrient deficiencies, being underwater, low humidity, etc.
Identifying the factors that prevent monstera leaves from splitting would help resolve them. This article gives a comprehensive overview of causes and remedies.

Why do Monstera leaves split? (window)
Windows is the term used to describe the holes and cracks in monstera leaves. Monstera leaf fenestration usually occurs after 2-3 years.
Monstera is often found under the canopy in the rainforest. Getting enough sunlight is quite difficult and the plant has to find ways to survive in this environment.
So why do monstera leaves split? To capture scattered sunlight, resist high winds, increase water access and more.
Let’s see how leaf divisions help monstera plants survive in their natural habitat. These survival traits also help this tropical plant withstand indoor growing conditions.
absorb sunlight
Sunlight is crucial for green plants. It helps in food production and also improves the uptake of water from the soil by the roots.
Split and pierced leaves increase surface area to trap scattered rays of the sun under the rainforest canopy.
It is an amazing property to allow the plant to tolerate low light. This allows the plant to survive in the house in indirect sunlight.

Improving access to water
The natural habitat of the monstera is characterized by heavy rainfall. The leaf separation function helps keep the rain out as much as possible.
The indentations in the leaves generally direct water to the nodes and root areas. Wet leaves are known to cause many problems including rotting, fungal and bacterial diseases.
The windows prevent water from staying on the leaves for a long time. This is the best way to avoid major problems on the leaves of monstera plants.
Tolerates strong wind
There is little wind in the natural habitat of monstera plants. Thanks to tall trees and large canopies that help keep strong winds from reaching the plant.
But the monstera is an invasive species and can survive in any area. Leaf division allows the plant to adapt to windy conditions when grown indoors.
The division protects the factory from being hit by a strong wind. Monsteras can easily adapt to harsh growing conditions.

Why aren’t my Monstera leaves splitting?
Every gardener looks forward to their monstera leaves after adopting one. But there are cases where fenestration may not occur.
Below are the possible reasons why monstera leaves do not split:
still too young
Age is a crucial factor to consider if your monstera leaves are windowless. Don’t expect young monstera plants to break the leaves.
Window formation usually occurs when the plant is about 2-3 years old. If your beauty isn’t there yet, don’t worry.
If this tropical plant does not open its leaves after the expected period, you will have to dig deeper and find out the cause of the problem.
insufficient sunshine
Monstera plants can tolerate low light. But if the plant doesn’t get enough light, it will probably grow slowly.
Insufficient sunlight causes monsteras to produce small leaves that cannot experience long-term windows.
Leggy growth and other disturbances caused by insufficient sunlight may be the possible reason for the leaves not opening.
nutritional deficiencies
Monsters don’t eat much. But monthly fertilization during the growing season is highly recommended. The nutrients help the plant produce bigger and healthier leaves.
Watering and humidity
Monsteras need more water and high humidity. Underwater and low humidity can prevent your houseplant’s leaves from having windows.
High humidity and enough water help the plant produce large leaves. It should be borne in mind that the natural habitat of monstera faces heavy rainfall and high humidity.

How to Encourage Monstera Leaves to Split?
Split sheets make a stunning statement in your living room or office. Here are some tips to help you divide monstera leaves:
Expose the plant to bright indirect light
Light is the most essential factor that promotes fenestration in monsteras. Plants that are in a shady area rarely break leaves at home.
Make sure your beauty is placed in an area where there is bright indirect light. I recommend placing the houseplant near the window.
You can also grow the plant under artificial light if sunlight is not enough. Make sure the light is not too bright to burn the leaves.
Constant watering routine
Tropical plants love water because their natural habitat is characterized by heavy rainfall. But you need to monitor your watering routine to avoid overwatering problems.
I recommend watering your beauty once a week in spring and summer. Water the plant about twice a month in winter.
The general rule is to check the moisture content of the soil before watering. Make sure the 2 to 3 inches of topsoil is dry before watering.
Apply fertilizer to the plant.
Monstera, like other plants, needs nutrients. But they are not big eaters. You need to provide the plant with a weak fertilizer during the growing season.
Sufficient nutrients help the plant produce bigger and healthier leaves. These leaves will experience fenestration later.
Remember not to fertilize monsteras in the winter. This is the period when the plant is dormant and the nutrients in the manure are toxic.
Ensuring optimal humidity and temperature
Monsteras prefer high humidity and temperature. Make sure your indoor growing conditions mimic the natural habitat of this tropical plant.
You can choose to install a humidifier to increase indoor humidity or move your houseplant to a bathroom with high humidity.
Another great option is to spray monstera leaves weekly. Helps increase humidity around the plant.
Remember to place the plant away from heat sources and vents. Excessive heat will make the plant drowsy and even burnt.
Consider replanting the planyou
Monsteras grow faster and often overwhelm grow pots. Failure to repot the plant will damage the root system due to the limited space available for growth.
Transplantation should not be done frequently. I recommend examining your plant to see if it has overgrown its current pot before considering repotting.
Spring is the best season to repot your plant. This is the period when the plant produces new growth. Large pots are ideal as they create enough space for root growth.
Pruning old foliage
Monsteras can be bushy if given a better growing environment. I recommend cutting off the old sheet to make room for the new sheet.
Pruning also helps keep monstera vines from growing all over the house. Removing old leaves allows the plant to direct energy and nutrients to new growth.
Fight pests and diseases
Monstera is less resistant to diseases and pests. Both of these factors are known to adversely affect the health of the plant and its leaves.
Some of the more common pests that infest the plant include spider mites, scale insects, thrips and aphids. These insects often pierce the leaves and suck up nutrients.
The small holes create an ideal environment for the spread of disease. The best option is to use a cotton swab soaked in insecticidal soap to kill the pests.

frequently asked Questions
When do Monstera leaves separate?
Monsteras begin to divide after reaching maturity in 2-3 years. Juvenile monsteras do not split leaves until they reach adulthood.
Do all Monstera leaves split?
Not all monsteras split leaves. There are certain varieties of monstera that do not have fenestration. But these varieties are quite rare. Note that young monstera plants do not split leaves.
Why are my Monstera leaves breaking?
This is usually due to mechanical damage. Sometimes the leaves can break if the air is too dry or if a fan is blowing nearby. Monstera leaves are large and can be easily stepped on.
Dividing existing Monstera leaves?
Absolute. But this is possible once the plant has reached maturity. Young monsteras do not fenestrate at all.
Do Monstera leaves split after unfurling?
Yes, the leaves start splitting when the plant is 2-3 years old. Even young leaves will have a window during this time.
Ultimately
Young monstera plants would not window right away. Don’t be frustrated, but wait until the houseplant is 2-3 years old.
The cracks and holes of Swiss Cheese Plant help make a statement in your home. The window offers unique features to decorate your home.
If you can’t wait to witness this attractive separation of monstera leaves, try to be more patient. Provide good growing conditions and requirements for best results.
