What Causes Leggy Monstera? How To Fix And Prevent

Leggy Monstera occurs mainly due to insufficient light, causing the plant to stretch towards the nearest light source, resulting in long stems with sparse leaves.

The problems that arise from Monstera plants are generally not far from inappropriate treatment. One of the most common issues is leggy growth due to inadequate lighting. Instead of growing upwards, your plants will grow long stems with sparse foliage.

Besides, the branches tend to lean on one side like a withered plant. Even though it’s not detrimental, leggy Monstera is undesirable because of the plant’s messy appearance.

Usually, people would prune a leggy Monstera to fix its appearance. However, is this the best way to solve the problem? We will answer these questions in the summary of the article below.

In addition, we include the causes and how to prevent it so you don’t have to deal with a leggy plant again. Let’s take a look!

Key Takeaways

  • Lack of light causes elongated stems.
  • High temperatures stress the plant.
  • Over-fertilizing leads to rapid, weak growth.
  • Pests weaken the plant, causing sparse leaves.
  • Wrong pot size restricts root growth, leading to legginess.

What Does “Leggy” Mean?

Actually, there is no specific definition of the Monstera leggy. This term arose because the growth habit of Monstera plants tends to lean to one side due to inadequate light.

In some cases, these plants even grow sloping above the ground to find a light source. The stems become elongated and sparse leaves wrap around like withered plants.

Not only that, but you will also notice pale leaves with a much smaller size compared to common Monstera plants.

And while Monstera is popular for their thick stem, leggy growth causes them to grow thinner. In addition, the distance between the rods will also widen and look messy.

Since Monstera is valued for its exquisite fenestrated leaves, this phenomenon is, of course, detrimental to ornamental plant lovers who grow them as natural decorations.

In addition to little light exposure, several factors cause your Monstera to become leggy. Check out the detailed explanation in the next section!

Why Monsteras Become Leggy?

Most Monstera lovers think that Monstera’s leggier growth is caused by a lack of sunlight. That’s true! Monstera requires at least 10-11 hours of bright indirect light to flourish.

However, there are some other factors that trigger such an unwanted phenomenon. What are those?

The Reasons Why Monsteras Become Leggy

1. Inadequate Light 

As we previously mentioned, inadequate sunlight is the main cause that leads your plants to grow tall and leggy.

Since Monstera needs gentle light, some think that they can put them in a low light condition.

Instead of stimulating healthy growth, it makes the plant suffer. In general, you will encounter such an issue in those that grow indoors, especially in the north-facing windows or behind the doors.

2. High Temperatures

Despite being tropical plants, Monstera cannot withstand hot temperatures. They favor cool weather, ranging around 65°F – 85°F, with the lowest at 50°F. Any temperature above 85°F can make them struggle to regulate their temperature.

Consequently, growing leggy and tall is the only way to help them cool down. Then, it will be followed by droopy and burn leaves, especially if you expose them to direct sun.

3. Over Fertilizing

Fertilizer is beneficial to improve growth as it adds more nutrients to the plants. However, too much application can stress out your Monstera. It can lead to fertilizer burn, showing off yellow leaves.

In addition, continuous application of fertilizers can cause salts to build up in the soil, inhibiting water absorption. Moreover, over fertilizing will accelerate leaf growth which makes it heavier.

If this condition is allowed, you will start to notice leggy growth.

4. Pests Infestation

Even though Monstera plants are hardy, they are not resistant to pests. Some pests that often invade the plant are mealybugs, spider mites, thrips, and scales.

These culprits will inhibit nutrient absorption and interfere with growth. Hence, you may expect leggy plants when attacked by those pests.

Besides, these insects can spread diseases that will lead to other serious problems for your Monstera.

5. Improper Pot Size

Pot or container size is crucial to make room for Monstera roots to develop. It must be adjusted to the size and type of plants you have. Monstera deliciosa will need a bigger pot, while Monstera Adansonii suits a small or medium one.

If you choose the wrong planter, the roots can outgrow the space as the Monstera grows older. They can grow leggy due to competition between oxygen and nutrients between roots.

How to Fix a Leggy Monstera?

If you have understood how to identify the causes of your leggy Monstera, it’s time to find the best way to fix it! Despite not being a life-threatening problem, leggy plants are not as attractive as home décor.

The long, bending, less leafy stems make Monstera look messy and unhealthy. Generally, Monstera lovers will immediately prune the branches.

By removing the leggy growth, you can also stimulate new leaves to grow. Just make sure to cut them above the nodes, around 45°, to accelerate the development.

Also, remember to use clean and sterilized knives or other cutting tools to ensure no cross-contamination occurs.

Furthermore, repotting is necessary at least once every two years to offer the roots more space to grow. It will prevent crowded roots while allowing better aeration and oxygen access.

Apart from that, this method also introduces a fresh potting mix, giving your Monstera additional nutrients to support their growth.

You also have to introduce your plants with support when the aerial roots start to grow. Or when the leaves grow bigger. It is crucial to avoid the stems bending over on one side. Apart from that, the trellis or cane helps your plant to climb just like in its natural habitat.

Along with the three methods we mentioned, ensure you also provide proper growing conditions. Your Monstera requires at least 10-11 hours of light exposure with a temperature of around 65°F – 85°F.

Rescue them inside if the outdoor temperature falls below 50°F to avoid frost damage. In case your plant needs fertilizer, apply it once a month during its growing period.

Don’t over fertilize to prevent root burn.

Monstera’s leggy growth is caused by improper care. So, the best way to address this underlying issue is to provide what your plants need. As a tropical plant, Monstera requires bright indirect light to thrive.

Without adequate sunlight, your plant will grow smaller leaves and become leggy.

In addition, you will start to see discoloration of the leaves, where they turn yellow and brown.

To prevent these issues, you can place your potted Monstera in an east-facing area where they can get gentle morning sun. Moreover, you can replace it with artificial light during winter when the sunlight is lacking to fulfill the growing requirement.

In addition, maintain a cool temperature in the range of 65°F – 85°F as it mimics their natural habitat.

If you grow them outdoors, you must provide shelter when the temperature drops below 50°F to prevent frost damage. Monstera also loves to grow in humidity, around 60-80%. You can set up a humidifier or a tray filled with pebbles and water.

Furthermore, choosing a pot is no less important to support your Monster growth and prevent leggy plants. Pots that are too small inhibit the growth of roots due to narrow space.

On the other hand, a bigger one can trap the water, which may lead to root rot. So, you must choose the right container according to the size of your plant.

After finding the ideal one, install a trellis for your plant to climb. It also prevents the leaves from dangling on the floor and becoming leggy. Additionally, once your plants grow too dense and heavy, prune them.

Make it a priority to prune any yellow or wilted leaves, as they consume too much energy.

Final Thoughts

Like other Monstera problems, leggy growth is caused by a lack of proper care. The main cause is the lack of sun exposure due to the planting location or placement of the pot. Other factors, such as hot temperatures, crowded roots, and pests, may also influence abnormal growth.

You can prevent this by providing their growing conditions, (e.g. offering enough light), along with choosing the right pot and doing regular pruning whenever you notice the top head grows dense and heavy.
