A monstera growing sideways can be fixed with the right support, light adjustments, and a little patience.
If your monstera is leaning to one side, it’s usually reaching for sunlight or struggling under its own weight.
The good news is that fixing a monstera growing sideways isn’t complicated, and most plants bounce back quickly once you address the root cause.
In this post, we’ll dig into why monsteras lean, how to fix a monstera growing sideways, and the best ways to keep your plant growing upright.
Let’s get started.
Why Your Monstera Is Growing Sideways
Before you can fix a monstera growing sideways, it helps to understand what’s causing the lean in the first place.
1. Your Monstera Is Reaching for Light
Monstera plants naturally grow toward their light source.
If your monstera is growing sideways, it’s probably stretching toward a window or bright spot in the room.
This behavior is called phototropism, and it’s completely normal for these tropical plants.
But when light only comes from one direction, your plant will lean more and more over time.
2. The Pot Is Too Small or Unstable
A top-heavy monstera in a lightweight pot can easily tip sideways as it grows.
If you’re dealing with a monstera growing sideways, check whether the pot is wide enough to support the plant’s weight.
A pot that’s too small makes the root ball unstable, and the whole plant shifts under its own weight.
3. The Stem Is Too Tall and Heavy
Monsteras are natural climbers, and in the wild they attach to trees and grow upward toward the canopy.
Indoors, without anything to climb, the stem gets heavy and slowly flops over.
This is one of the most common reasons people notice a monstera growing sideways.
The leaves are large and hold a lot of weight, so the stem simply bends under the load.
4. Watering and Root Health Issues
Overwatering can weaken the roots, and weak roots can’t hold the plant upright.
If your monstera is growing sideways and the soil stays soggy, root rot might be the real culprit.
On the flip side, underwatering can make the stems soft and limp.
Healthy roots are absolutely essential for keeping a monstera growing straight and strong.
How to Fix a Monstera Growing Sideways
Now that you know why it happens, let’s walk through the actual steps to fix a monstera growing sideways.
1. Add a Moss Pole or Stake
The most effective way to fix a monstera growing sideways is to give it something to climb.
Insert a moss pole or sturdy stake into the pot, close to the base of the stem.
Gently tie the stem to the pole using soft plant ties, velcro strips, or even twine.
As the monstera grows, it will naturally attach to the pole with its aerial roots.
This not only fixes the sideways growth but also encourages bigger, healthier leaves.
2. Rotate Your Monstera Regularly
If your monstera is growing sideways because of uneven light, rotating the pot will work wonders.
Give your plant a quarter turn every week or two.
This way, all sides of the plant get equal light exposure.
Over a few weeks, you’ll notice the stem starting to straighten out.
And the plant won’t have a reason to lean in any one direction anymore.
3. Repot Into a Heavier, Wider Container
Sometimes you need to fix a monstera growing sideways by upgrading its home.
Choose a pot that’s two to four inches wider than the current one.
A ceramic or terracotta pot will add valuable weight and stability.
Make sure the new pot has drainage holes to prevent waterlogged soil.
While you’re at it, check the roots and trim away any that are mushy or rotting.
4. Prune Heavy or Damaged Growth
If your monstera is growing sideways because a stem is too long and heavy, pruning can help.
Cut back the longest stems just above a node, and you can propagate the cuttings in water.
This reduces the weight on the plant and encourages bushier, more upright growth.
You don’t have to prune a lot, just enough to remove the worst of the lean.
With a few strategic cuts, fixing a monstera growing sideways becomes much easier.
5. Adjust the Lighting Setup
To stop your plant from leaning, give it bright, indirect light from multiple angles.
Place it near a bright window but not in harsh direct sun.
If you only have one window, adding a grow light on the opposite side can balance things out.
And remember to rotate the pot regularly, just as we talked about earlier.
This simple change can prevent a monstera growing sideways from ever becoming a big problem.
Preventing a Monstera from Growing Sideways
Once you fix a monstera growing sideways, you’ll want to keep it that way for good.
1. Give It a Climbing Support Early
The best time to add a moss pole is when your monstera is still young.
If you wait until the plant is already leaning, you’ll have to wrestle it back into place.
Adding support early means the plant grows upward naturally.
That way, a monstera growing sideways is something you simply never have to deal with.
2. Maintain Steady Care Habits
Monsteras love consistent watering, humidity, and feeding.
Water when the top inch of soil feels dry, and keep humidity around 50 to 60 percent.
Feed with a balanced liquid fertilizer once a month during the growing season.
A well-cared-for plant is a strong plant, and strong plants don’t flop over.
3. Monitor Growth and Adjust as Needed
Check your monstera every couple of weeks.
Loosen any ties that might be digging into the stem as the plant thickens.
Move the pole if the plant has shifted, and rotate the pot as part of your routine.
Catching a slight lean early is far easier than fixing a monstera growing sideways that’s been left too long.
So, How Do You Fix a Monstera Growing Sideways?
You can fix a monstera growing sideways by giving it a moss pole, rotating the pot, repotting into a heavier container, pruning heavy stems, and adjusting the light source.
The process takes a few weeks, but your monstera will gradually straighten up and start growing the way it should.
The earlier you catch the lean, the easier the fix, so don’t wait until your plant is practically horizontal.
With the right support and a little attention, your monstera will be standing tall and looking gorgeous in no time.
