Determining the age of a Monstera plant might seem puzzling, but with a keen eye, one can observe certain factors that indicate its stage of growth. Discerning the age of Monstera plants can be helpful for proper care and maintenance, ensuring these popular houseplants remain healthy and happy. In this article, readers will gain insight into various signs that reveal the age of Monstera plants, as well as how to tend to their needs at different stages of growth.

Inspecting Physical Characteristics

Size and Growth

Monstera plants grow differently depending on their environment and age. Generally, younger plants may be smaller in size and have slower growth rates. In the first few years, you can measure a plant to roughly determine its age, especially if it’s growing indoors. Outdoor Monsteras may grow longer, allowing for age determination beyond seven years.

Leaf Development

Leaf development in Monstera plants is an important indicator of age. Young plants usually have small, heart-shaped leaves without holes. Over time, the leaves grow larger and develop holes, also known as fenestrations. Leaf fenestration typically occurs when the plant is around 2-3 years old. Factors such as sunlight, water, humidity, and fertilization need to be considered to ensure the plant develops these fenestrations.

Aerial Roots

Aerial roots are another physical characteristic to consider when estimating the age of a Monstera plant. These roots grow from the stem, helping the plant to climb and anchor itself. As the plant ages, the aerial roots become more numerous and elongated. Observing the development of aerial roots can provide insight into the plant’s age and overall growth.

Analyzing Growth Patterns

New Leaf Production

One way to estimate the age of a Monstera plant is by observing its new leaf production. In their early growth stages, Monstera plants grow more rapidly, with new leaves often sprouting every few weeks. As the plant matures, its growth rate slows down, and new leaves may appear less frequently, such as once per month or even less often.

Maturity-Related Changes

An important factor to consider when determining the age of a Monstera is the presence of fenestrations, or holes, in its leaves. These distinctive features start to appear during the juvenile phase, which typically occurs when the plant is at least 2 to 3 years old. Before this age, the leaves of a Monstera will generally be solid without any fenestrations.

As the Monstera plant continues to mature, the fenestrations will become more numerous and pronounced. The size of the leaves may also increase over time, with larger leaves being indicative of an older, more mature plant. It is crucial to keep in mind, however, that environmental factors, such as sunlight exposure, can also influence fenestration development and leaf size.

In summary, to analyze the growth patterns of a Monstera plant and determine its approximate age, observe the rate of new leaf production and the appearance of maturity-related changes, such as fenestrations and leaf size. Keep in mind that no method is foolproof, as environmental factors can also influence a Monstera plant’s growth and appearance.

Consulting Expert Sources

When determining the age of a Monstera plant, consulting expert sources can be helpful. These sources can provide valuable information on how to identify the different growth stages of Monstera plants and offer tips on how to care for them properly.

Nursery or Plant Shop

One of the best places to start when trying to determine the age of a Monstera plant is to consult with a local nursery or plant shop. The staff members at these establishments are often knowledgeable about various plant species, including Monstera plants. They can provide insight into the development stages of a Monstera based on the appearance of its leaves and overall growth.

  • Ask about leaf shapes and sizes to determine approximate age
  • Discuss fenestrations and their appearance in certain age ranges
  • Consider the overall size and growth patterns of the plant

Online Communities

Another useful source of information for determining the age of a Monstera plant is through online communities. These online forums and social media groups often consist of plant enthusiasts who have extensive knowledge and experience with Monstera plants. By participating in these communities, you can:

  • Share photos of your Monstera plant for others to evaluate
  • Ask questions about specific characteristics and their relationship to age
  • Learn from others’ experiences with Monstera plants in different growth stages

Keep in mind that while expert sources can assist in identifying the age of a Monstera plant, it’s important to note that variables such as growing conditions and plant health can influence the appearance and growth of a Monstera. It’s essential to give your Monstera the proper care to ensure its healthy growth and longevity.


Determining the age of a Monstera plant can be a challenging task due to the varying growth rates and conditions. There are, however, some indications that can help provide an estimate of the plant’s age.

One important aspect to consider is the shape and fenestration of the Monstera’s leaves. Young Monsteras, usually under 2 to 3 years old, tend not to have split leaves, whereas older plants often exhibit fenestrations.

Another factor that can help provide a rough estimation of the plant’s age is its growth rate. A healthy Monstera typically grows between 1 to 2 feet per year, or approximately one-third of an inch per day in its initial years. Measuring the plant’s height can give a general idea of its age, especially during the first 5 to 7 years.

In conclusion, while it might be difficult to pinpoint the exact age of a Monstera plant, considering aspects such as leaf development, growth rate, and environmental conditions will offer a decent estimate. Remember, proper care, ample sunlight, and a nurturing environment will help your Monstera thrive and grow, living a lengthy and prosperous life.
