Why Is My Monstera Growing Sideways?: [8 Reasons & Fixes]

The Monstera deliciosa, often simply called Monstera, is a tropical plant native to the rainforests of Central America. Scientifically classified within the Araceae family, this striking plant is known for its unique, split leaves and its ability to adapt to various indoor conditions. In a controlled environment, Monstera deliciosa usually grows to a height of 6 to 10 feet and showcases a climbing habit facilitated by aerial roots.

Why is your Monstera growing sideways instead of upwards? The most common reason for this atypical growth direction is insufficient light, leading the plant to stretch out in search of better lighting conditions. Addressing this issue is crucial for the balanced, vertical growth of your Monstera.

This article covers a comprehensive range of factors that influence the growth direction of your Monstera. From light conditions, space, and pruning techniques to soil quality, pests, and even genetic factors, we’ll guide you through actionable solutions for each contributing factor. You’ll learn not just how to correct sideways growth but also how to optimize the overall health and beauty of your Monstera.

1. The Prime Suspect: Why Light Matters Most

When it comes to solving the sideways growth mystery of your Monstera, think of light as your prime suspect. It’s not just about turning on a light switch; there are various factors at play here.

You remember photosynthesis from school, right? It’s the process by which plants convert light into energy. Without sufficient light, your Monstera can’t perform photosynthesis effectively. This leads to weaker stems and leaves, which in turn makes your Monstera more likely to grow sideways.

1. The Prime Suspect Why Light Matters Most

Phototropism is the phenomenon that explains why your Monstera grows towards the light. In a low-light environment, your Monstera will stretch itself out to find a light source, often leading to unbalanced and sideways growth.

Types of Light and Their Impact

  1. Direct Light: Generally too harsh for Monsteras and can cause leaf burn.
  2. Indirect Light: Ideal for Monsteras; bright but not directly hitting the plant.
  3. Low Light: Not sufficient for healthy growth and likely leads to sideways growth.

How to Fix the Light Problem

  • Light Meters: These gadgets measure the amount of light in a given area and can help you find the ideal location for your Monstera.
  • Artificial Lights: LED grow lights can supplement natural light, especially during winter months.
  • Light Rotation: Regularly rotate your Monstera so that all sides get equal exposure to light.

2. Room to Grow: The Impact of Limited Space

Just as you’d struggle to stretch out in a cramped apartment, your Monstera needs room to grow to achieve its full, upright potential.

Roots are the foundation of any plant. When the roots of your Monstera are cramped, they can’t provide the support the plant needs for upward growth. Instead, the plant starts growing sideways to find room.

When a plant is “root-bound,” its roots have completely taken up the space within the pot, often circling around the bottom. This makes it difficult for the plant to take up nutrients and water, leading to poor growth and even sideways growth.

2. Room to Grow The Impact of Limited Space

Signs Your Monstera is Cramped

  • Slow Growth: A clear sign that your Monstera is uncomfortable.
  • Yellowing Leaves: Could be a sign of stress due to limited space.
  • Visible Roots: Roots coming out of the drainage holes are a dead giveaway.

Table: Signs of Limited Space and Their Solutions

Solutions for Space Issues

  1. Repotting: Ideally, you should be repotting your Monstera every 18–24 months. Use a pot that is at least 2 inches larger in diameter than the current one.
  2. Root Pruning: This is a bit more advanced, but if you’re comfortable, you can prune some of the roots to give your Monstera a bit more breathing room.
  3. Pruning the Foliage: Sometimes, trimming the leaves and stems can help the plant focus its energy on root growth, which can later support more balanced upward growth.

3. Watering and Nutritional Balance: Your Plant’s Diet

Proper watering and nutrition aren’t just buzzwords; they’re the bread and butter—or should we say, the “water and sunlight”—of your Monstera’s health. Let’s dive into the nitty-gritty details.

Water isn’t just H2O for plants; it’s the medium through which they absorb essential nutrients from the soil. Inadequate or excessive watering can disrupt this delicate balance, leading to various growth issues, including our prime concern: sideways growth.

Plants need a variety of nutrients, including macronutrients like nitrogen, phosphorus, and potassium, and micronutrients like calcium and magnesium. Each of these plays a unique role in plant health, from root development to leaf growth.

Too little water, and the plant can’t absorb nutrients. Too much, and you risk nutrient leaching, where essential nutrients are washed away from the soil.

Solutions for Dietary Dilemmas

Watering Techniques

  1. Bottom Watering: This involves filling the saucer under the pot so the plant can absorb water from the bottom. This method reduces the risk of leaf rot.
  2. Top Watering: This is the traditional method but be careful not to waterlog the soil.

Fertilizer Facts

  1. Organic vs. Chemical: Organic fertilizers release nutrients slowly and improve soil structure but can be expensive. Chemical fertilizers are cheap and fast-acting but can harm the soil in the long term.
  2. Frequency: During the growing season, a monthly application is usually sufficient.

Quick Tips for Balanced Nutrition

  1. Test the Soil: Use a soil test kit to check nutrient levels.
  2. Observe Leaf Color: Yellow leaves often indicate a nitrogen deficiency.
  3. Tailored Fertilizers: Some fertilizers are specially formulated for tropical plants like Monstera.

4. The Right Cut: How Pruning Affects Growth

Ah, pruning—the haircuts of the plant world. But unlike a bad haircut, poor pruning can have long-lasting effects on your Monstera’s health and direction of growth.

Understanding the basic anatomy of your plant is crucial for effective pruning. Monsteras have nodes and internodes along their stems. Nodes are the segments where leaves and roots grow, and internodes are the stem segments between nodes.

Improper cutting techniques, cutting at the wrong time of year, and even using dull tools can lead to a host of problems. These range from stress and disease susceptibility to, you guessed it, sideways growth.

Proper Pruning Techniques

The Ideal Cut

  1. Angle: Always cut at a 45-degree angle to avoid water pooling on the cut surface.
  2. Location: Make your cut just above a node, where the plant has a better chance of healing itself.

Tools of the Trade

  1. Pruning Shears: Ideal for thicker stems.
  2. Scalpels or Sharp Knives: Good for finer, more precise cuts.

When to Prune

  1. Growing Season: Late spring to early summer is ideal.
  2. Signs of Stress: If your plant is already stressed, it’s not a good time to prune.

Solutions for Pruning Problems

  1. Regular Inspection: Keep an eye on your Monstera and plan to prune when you start noticing overgrowth or dead leaves.
  2. Professional Help: If you’re unsure, don’t hesitate to seek advice from a professional.

5. A Helping Hand: The Role of Support Structures

Sometimes, even plants need a little support from their friends—that’s where support structures come into play. If your Monstera is growing sideways, it might just be crying out for a sturdy support system.

In its natural rainforest habitat, the Monstera deliciosa has plenty of trees and vines to climb and lean on. But inside your living room? Not so much. It’s up to you to provide the necessary structures.

When Monsteras can’t find something to cling to, they start to sprawl out, often leading to sideways growth. This is because their aerial roots are looking for something to attach to and, not finding it, the plant grows in any direction it can.

Types of Support Structures

Moss Poles

Moss poles mimic the natural environment of a Monstera by providing a moist, textured surface for aerial roots to cling to. They are the most commonly used support for Monsteras.


Wooden or metal trellises offer a flat structure for your Monstera to climb. These can be particularly effective for larger Monsteras.

DIY Options

Some folks use a combination of stakes and fishing lines or even repurpose old ladders as unique support structures.

How to Support Your Monstera

  1. Installation: Whether it’s a moss pole or a trellis, make sure it’s securely anchored in the potting soil.
  2. Training the Plant: Gently attach the Monstera’s stem to the support using soft plant ties or clips.
  3. Ongoing Care: As the plant grows, you’ll need to reposition the ties and possibly extend the support structure.

6. It’s in the Genes: Genetic Factors in Growth

Sometimes, despite your best efforts, your Monstera may still grow sideways. It could be something you can’t control: genetics.

There are several species and cultivars of Monstera, each with its own genetic predispositions. Some are naturally more inclined to grow upwards, while others may have a tendency to grow sideways.

Some Monsteras have genetic traits that make them more prone to sideways growth. These can include shorter internodes, weaker stems, and even a natural tendency for vine-like growth.

Solutions for Genetic Challenges

Pruning and Propagation

If you have a Monstera variety that is genetically predisposed to grow sideways, strategic pruning can encourage more upright growth. Propagation allows you to create new plants from the pruned sections, which you can train to grow upright from an early stage.

Selective Cultivation

Another approach is to selectively cultivate your Monstera, choosing stems that show more upright growth for propagation. Over time, you can essentially “train” your Monstera population to grow more vertically.

When to Consult a Botanist

If you’re really stumped by your Monstera’s growth pattern, it might be worth consulting a botanist. They can help identify the specific variety you have and offer tailored advice for encouraging upright growth.

7. Soil and Container Essentials: More than Just Dirt

The soil you use for your Monstera is far from trivial. It’s the plant’s home, its food source, and its support system all rolled into one. Let’s dig into this topic, shall we?

Soil is more than just dirt; it’s a complex structure of minerals, organic matter, water, and air. A well-structured soil provides the roots with adequate room to grow and allows for good drainage, which is vital for preventing root rot.

Monstera prefers a slightly acidic to neutral soil pH, typically between 5.5 and 7.0. Incorrect pH levels can lead to nutrient imbalances, affecting your Monstera’s growth.
