Monstera plants, with their signature hole-filled leaves, are a popular houseplant for many enthusiasts. However, some may wonder why their Monstera leaves lack these iconic fenestrations. In this article, the reasons behind the absence of holes in Monstera leaves will be discussed, providing readers with a comprehensive understanding of this fascinating plant feature.

Factors such as the age of the plant, growing conditions, and overall plant care can contribute to the presence or absence of fenestrations in Monstera leaves. Exploring these factors in detail will help plant owners develop greater insight into how to encourage the growth of those distinctive, split leaves.

By the end of this article, readers will have a solid grasp on the contributing factors to Monstera leaf fenestrations, equipping them with the knowledge to cultivate beautiful, hole-riddled Monstera plants in their own homes.

Understanding Monstera Leaves

Monstera is a tropical plant with distinct large leaves, often showcasing unique holes or fenestrations. Knowing more about the anatomy and growth patterns of these leaves, as well as the role of these holes, helps understand why some Monstera leaves might not have the characteristic holes.

Anatomy and Growth Patterns

Monstera leaves are made up of a glossy and heart-shaped design when they are young. As the plant matures, the leaves develop fenestrations or holes, which give them their unique appearance. These holes start to appear when the plant is typically 2-3 years old. Factors such as the amount of sunlight, water, humidity, and fertilization can affect the growth and overall appearance of these holes in Monstera leaves.

Role of Holes in Monstera Leaves

The holes in Monstera leaves serve multiple functions. One of the primary reasons these leaves have holes is to capture maximum light, as they compete with other plants for sunlight exposure in their native rainforest environment. The fenestrations also play a part in allowing rainwater to pass through the leaves without causing damage, and providing camouflage against potential predators.

In addition, the holes in the leaves increase the overall surface area available for light absorption, thus promoting further growth and development. Understanding the importance and role of these holes in Monstera leaves can guide proper care and help address concerns about the lack of fenestrations in the leaves of a younger or less mature plant.

Factors Affecting Hole Formation

Age of the Plant

One of the primary factors influencing hole formation in Monstera leaves is the plant’s age. Young Monstera plants may not develop fenestration, or holes, as this feature tends to appear when the plant matures. It is normal for younger Monsteras to have leaves without fenestrations.

Light Exposure

Light exposure plays a crucial role in Monstera’s growth and hole formation. These plants thrive in indirect sunlight, which helps support photosynthesis and produce energy. Insufficient light exposure can inhibit the development of fenestrations, leaving the leaves with fewer or no holes at all.

Watering and Drainage

Proper watering and drainage are essential for the overall health of a Monstera plant. Overwatering, underwatering, or poor drainage can lead to stress, impeding the formation of fenestration in the leaves. Ensure that your Monstera has well-draining soil and receives an appropriate amount of water.


Proper fertilization ensures that Monstera plants receive adequate nutrients necessary for their growth and development of fenestrations. A well-balanced fertilizer can provide the essential nutrients and promote robust growth, contributing to the formation of leaf holes.

Temperature and Humidity

Temperature and humidity are important environmental factors for Monstera plants. They thrive in warm and humid conditions, which are similar to their natural habitat in tropical rainforests. Extreme temperature fluctuations or low humidity can cause stress to the plant, potentially affecting the appearance of fenestrations in the leaves.

Common Issues and Solutions

Inadequate Light

Insufficient light is a common reason why Monstera leaves may not develop holes. These plants thrive in bright, indirect sunlight which facilitates their photosynthesis, allowing them to grow and develop unique leaf fenestrations. To resolve this issue, ensure that your Monstera is placed in a well-lit area that receives indirect sunlight for optimal growth.

Improper Watering

Another factor that can prevent Monstera leaves from developing holes is inconsistent or improper watering. Monsteras prefer their soil to be consistently moist, but not waterlogged. To maintain proper moisture levels, do the following:

  • Water your Monstera when the top 1-2 inches of soil feel dry.
  • Avoid letting the soil dry out completely, as this can cause leaf browning.
  • Ensure your plant is in well-draining soil and has drainage holes in its pot to prevent overwatering.

Lack of Nutrients

Monsteras require adequate nutrition to grow and develop fenestrations in their leaves. If your plant is not receiving the necessary nutrients, its growth may be stunted, leading to leaves without holes. To address nutrient deficiencies, consider the following:

  • Feed your Monstera with a balanced liquid fertilizer during the growing season (spring and summer) every 4-6 weeks.
  • In the fall and winter, reduce fertilization to once every 8-10 weeks.
  • Ensure that the potting mix you use provides the necessary nutrients for your Monstera to thrive.

Temperature and Humidity Issues

Monsteras are tropical plants and require consistently warm temperatures and high humidity levels to thrive. If your Monstera is not developing holes in its leaves, it might be due to temperature or humidity issues. To create an optimal environment for your Monstera, consider the following:

  • Maintain a consistent room temperature between 65-85°F (18-29°C).
  • Keep your Monstera away from drafts, air conditioners, or heating vents that could cause temperature fluctuations.
  • Increase humidity levels around your plant by using a humidifier, placing a tray of water nearby, or misting the leaves regularly.

Preventative Measures for Healthy Monstera Growth

Proper Potting and Soil

A crucial aspect of Monstera plant care is providing the appropriate potting and soil conditions to ensure healthy growth. Select a well-draining pot with adequate drainage holes to prevent waterlogging. Utilize a high-quality potting mix that contains peat or coconut coir, perlite or pumice, and some organic matter, allowing for proper aeration and moisture-retention.

Fertilization Practices

Monstera plants need the right balance of nutrients to develop those distinct holes in their leaves. It’s vital to use a balanced fertilizer with proper nitrogen, phosphorous, and potassium ratios. Fertilize your Monstera once a month during the growing season, typically from spring to early fall, and reduce it to every two or three months during winter.

It’s essential to avoid overfertilizing, as excessive nitrogen can lead to rapid growth with elongated stems and internodes, affecting the plant’s overall health.

Pruning and Maintenance

Regular pruning and maintenance of your Monstera plant encourage healthy and controlled growth. Remove dead or damaged leaves and trim long, spindly stems or vines to maintain a desirable shape. Additionally, provide appropriate support, like a moss pole or trellis, to help your Monstera climb and grow vertically.

Another essential maintenance practice is to regularly inspect your plant for pests, such as mealybugs or spider mites, and treat as needed. Remember to keep the humidity around your plant at a sufficient level, ensuring its optimal growth.


In summary, the appearance of holes or fenestrations in Monstera leaves is influenced by several factors. These include the age of the plant, the growing conditions, and the species of Monstera. Young Monsteras usually begin developing fenestrations when they are 2-3 years old and have grown to a certain size.

Optimal growing conditions, such as sufficient sunlight, play a crucial role in the formation of fenestrations. Monsteras in their natural habitat grow tall to compete for sunlight, and the holes in their leaves help maximize light absorption, allowing rainwater to pass through without causing damage, and providing camouflage against predators.

It is important to create suitable environmental conditions for your Monstera to develop these characteristic holes, including proper lighting and care. While some species may not produce split leaves, proper conditions can encourage fenestrations in those that are programmed by nature to have them. Ensuring adequate care and patience can lead to a thriving Monstera with the distinctive, beautiful leaves it is known for.
