If you’ve noticed that your monstera plant’s leaves are getting smaller, there could be several factors causing this change. Factors such as improper watering, lack of nutrients, inadequate light, low humidity, harsh temperatures, and overfertilization can all contribute to smaller monstera leaves.

Adjusting the care and environment for your monstera is crucial to promoting healthy growth and addressing the issue of reduced leaf size. In this article, we will explore these factors in detail and provide guidance on how to promote larger, healthier leaves on your monstera plant.

Factors Affecting Leaf Size

Light Exposure

One crucial factor determining the size of Monstera leaves is light exposure. Insufficient sunlight can lead to smaller leaves, as the large leaves serve important functions, including optimal energy absorption.

Fertilization Needs

Another significant factor is the plant’s fertilization needs. The presence of too much or too little fertilizer can influence Monstera leaf size, so it’s essential to provide the proper nutrients for the plant’s growth.

Room Temperature

Room temperature also plays a role in Monstera leaf size. Harsh temperatures can cause leaves to grow smaller, so maintaining a suitable environment is important for healthy growth.


Lastly, humidity affects Monstera leaf size. Low humidity levels can lead to smaller leaves, as the plant struggles to maintain the moisture necessary for ideal growth conditions.

Potential Underlying Issues


One cause of smaller leaves in Monstera plants is overwatering. When Monstera plants receive too much water, they struggle to take up the necessary nutrients, leading to unhealthy growth and smaller leaves.


Conversely, underwatering can lead to smaller leaves in Monstera plants. When Monstera plants don’t receive enough water, they have difficulty sustaining growth and producing larger, healthy leaves.

Poor Nutrition

Poor nutrition is another common cause of smaller leaves in Monstera plants. Insufficient intake of essential nutrients can result in slow growth and the development of smaller leaves, impacting the overall health of the plant.

Corrective Measures

Light Adjustment

Ensuring your monstera has access to adequate light can help promote healthy growth and larger leaves. Place the plant near a window that receives indirect sunlight to avoid causing damage due to direct sun exposure.

Proper Watering Techniques

Consistent and appropriate watering is crucial for monstera health. Avoid over or under-watering your plant, as this can lead to smaller leaves. Ensure the soil remains moist but not soggy, and allow the top layer to dry out slightly between waterings.

Fertilization Recommendations

Providing proper nutrition is essential for promoting large, healthy monstera leaves. Use a balanced, slow-release fertilizer and follow the package instructions regarding application frequency and amounts. Additionally, test and adjust the soil pH to a neutral range of 6.0 to 7.0 to prevent nutrient deficiencies that can result in stunted growth and smaller leaves.


In summary, the primary reasons behind smaller monstera leaves include overwatering, underwatering, insufficient light, nutrient deficiencies, low humidity, and temperature extremes. Addressing these factors and ensuring proper care will promote healthy growth and larger leaves for your monstera plant.
