In a dance that intertwines the radiant threads of sun and shadow, the Monstera deliciosa affectionately dubbed the Swiss cheese plant, basks in its unique monstera sun need.
This living emblem of the tropics crafts a verdant dreamscape within our homes, its distinctive leaves punctured with nature’s own exquisite embroidery.
However, like all living beings, Monsteras have their preferences and needs. One of the most critical factors influencing their health and growth is sunlight.
Sunlight plays a pivotal role in photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth.
For a Monstera, getting the right amount of sunlight can mean the difference between a thriving, vibrant plant and one that’s struggling to survive.
How Much Light Does a Monstera Require?
Understanding the sunlight needs of your Monstera plant involves more than just knowing it prefers bright, indirect light.
Bright, Indirect Light Explained
“Bright, indirect light” is a term often used in plant care, but what does it mean?
- Bright Light: This doesn’t mean direct sunlight. Instead, it refers to a location that is well-lit for most of the day. It could be near a window that gets plenty of natural light, but not where the sun’s rays can directly hit the plant.
- Indirect Light: This means the light does not hit the plant directly. Instead, it might be filtered through a curtain or bounced off a wall or other surface.
Ideal Placement for Monstera
- Near a north or east-facing window, where the sunlight is generally softer.
- If you only have south or west-facing windows, use a sheer curtain to diffuse the light and prevent direct sunlight from hitting the plant.
- Place the plant a few feet away from the window, where it can still get plenty of light without the risk of sunburn.
Sunlight and Monstera’s Health
Sunlight plays a crucial role in Monstera’s growth and overall health.
- Photosynthesis: Sunlight fuels photosynthesis, the process by which plants convert light energy into the chemical energy they need to grow.
- Leaf Development: The right amount of sunlight encourages the development of the Monstera’s unique leaf perforations.
- Color: Adequate sunlight promotes a vibrant green color in the leaves.
Understanding Light Levels
|Light Level||Description||Effect on Monstera|
|Low||Far from windows or in a room with little natural light.||Growth may slow, and the distinctive leaf perforations may not develop fully.|
|Medium (Ideal)||Near a window but out of direct sunlight, or in a well-lit room.||Ideal for growth and development of leaf perforations.|
|High||Direct sunlight for several hours a day.||Can cause leaf burn and damage the plant.|
As shown in the table, Monsteras do best in medium light conditions. However, they’re quite adaptable and can tolerate a range of light conditions.

The Effects of Too Much Sunlight
While Monsteras need sunlight for photosynthesis and growth, too much of it, especially direct sunlight, can be harmful.
This is because Monsteras, in their natural habitat, are accustomed to the dappled sunlight of the rainforest floor, not the intense, direct sunlight of more exposed environments.
Signs of Sunburn in Monstera
If your Monstera is getting too much sunlight, it may show signs of sunburn.
- Yellow or Brown Leaves: If the leaves of your Monstera are turning yellow or brown, particularly on the side facing the sun, this could be a sign of sunburn.
- Crispy Patches: Sunburn can also cause parts of the leaves to become crispy and dry. These patches are often brown and may appear bleached or faded.
- Leaf Drop: In severe cases, a sunburned Monstera may drop leaves as it struggles to cope with the damage.
Long-term Effects of Excessive Sunlight
Excessive sunlight can have several long-term effects on your Monstera:
- Stunted Growth: Over time, the damage from sunburn can stunt your Monstera’s growth. The energy the plant would use for growth is instead used to repair the damage.
- Reduced Lifespan: Chronic sunburn can reduce the overall lifespan of your Monstera. The continuous stress and damage can weaken the plant, making it more susceptible to diseases and pests.
- Loss of Leaf Perforations: Monsteras are known for their unique leaf perforations. However, too much sunlight can cause new leaves to grow in without these characteristic holes.
The Effects of Too Little Sunlight
Just as too much sunlight can harm your Monstera, so can too little. Monsteras are tropical plants that need a certain amount of light to thrive.
If they don’t get enough, they can’t photosynthesize effectively, which can lead to a variety of problems.
Signs of Insufficient Sunlight
If your Monstera isn’t getting enough light, you might notice the following signs:
- Leggy Growth: One of the first signs of insufficient light is leggy growth. This means the plant is stretching out towards the light source, resulting in long stems with large spaces between leaves.
- Small Leaves: If your Monstera is not getting enough light, its leaves may grow in smaller than usual. This is because the plant is conserving energy due to the lack of light.
- Lack of Leaf Perforations: One of the Monstera’s defining features is the perforations, or holes, in its leaves. Without enough light, new leaves may grow in solid, without these characteristic perforations.
- Dull, Dark Leaves: A lack of sunlight can cause your Monstera’s leaves to become darker and lose their vibrant green color.
Long-term Effects of Inadequate Sunlight
In the long term, inadequate sunlight can have serious effects on your Monstera:
- Stunted Growth: Without enough light for photosynthesis, your Monstera may grow very slowly or not at all.
- Weak Plant: A lack of sunlight can weaken your Monstera, making it more susceptible to pests, diseases, and other stressors.
- Reduced Lifespan: In severe cases, a prolonged lack of sunlight can shorten your Monstera’s lifespan.
If you notice any of these signs, it might be time to move your Monstera to a brighter location. But remember, it’s all about balance – you want to increase the light your Monstera receives without exposing it to harsh, direct sunlight.
Balancing Sunlight and Shade for Monstera
Achieving the right balance of sunlight and shade for your Monstera can feel like a delicate dance. But with a bit of knowledge and observation, you can create the perfect lighting conditions for your plant.
Finding the Ideal Spot: A Game of Shadows
The ideal placement for your Monstera is in a spot that receives lots of direct light that is bright.
This could be near a window with eastern or northern exposure, where the light is usually softer.
If you only have windows with southern or western exposure, which tend to receive more intense light, consider using a sheer curtain or blinds to diffuse the light and prevent direct sunlight from hitting the plant.
Monsteras are used to growing under the cover of large trees in the rainforest, so they’re accustomed to filtered dappled light. A spot that mimics these conditions is what you’re aiming for.
Artificial Light: The Helping Hand
In some cases, natural light might not be enough, especially during the darker winter months or if you live in a home with limited natural light. This is where artificial light can play a role.
Fluorescent lights, particularly those with a high output, can be a good source of supplemental light for your Monstera.
They emit a spectrum of light that is beneficial for plants and don’t produce a lot of heat, so they can be placed close to your plant without the risk of causing heat damage.
LED grow lights are another option. They’re energy-efficient and emit light in a spectrum that’s ideal for photosynthesis.
Plus, they’re available in a variety of forms, from bulbs that can be used in regular light fixtures to larger panels for bigger plants or multiple plants.
Yes, Monsteras can tolerate low light better than many other houseplants. However, they won’t thrive in these conditions.
Yes, Monsteras can get too much light. While they need bright light to thrive, too much direct sunlight can cause sunburn.
A happy Monstera will have vibrant green leaves, steady growth, and new leaves will develop characteristic perforations or “holes”.
Absolutely! Artificial light, such as fluorescent lights or LED grow lights, can supplement natural light, especially in darker homes or during the winter months.
Caring for a Monstera plant is a pleasurable experience that adds a tropical flair to your house.
One of the most important components of Monstera care is making sure it gets enough sunshine. Monsteras, as we’ve learned, like bright, indirect light that replicates the dappled sunshine found in their native jungle home.
Too much direct sunlight can lead to sunburn, while too little light can result in leggy growth and a lack of characteristic leaf perforations.
Striking the right balance is key to a healthy, thriving Monstera.
