Pothos are naturally trailing plants, so long vines aren’t always a problem. The issue is when the stems become unusually stretched, leaves become widely spaced, and the plant starts looking thin or uneven.
Fortunately, you can usually improve a leggy pothos with a combination of better light, strategic pruning, proper watering, and propagation.
If you’re growing pothos in a terrarium, there are a few additional things to consider because terrariums can retain moisture and limit the amount of available space.
What Does a Leggy Pothos Look Like?
A leggy pothos typically has long sections of bare or lightly leafed stem between its leaves.
You may notice:
- Long, stretched vines
- Large gaps between leaves
- Small new leaves
- Sparse growth
- Vines growing strongly toward a window or light
- Leaves concentrated near the ends of vines
- Uneven growth on one side of the plant
It’s important to distinguish normal trailing growth from legginess.
A healthy pothos can produce long vines. The problem is usually excessive spacing between leaves combined with weak or sparse growth.
Why Is My Pothos Leggy?
1. Not Enough Light
The most common reason for a leggy pothos is insufficient light.
Pothos are adaptable plants and can survive in lower-light conditions. However, low light can cause slower and more stretched growth.
When the plant doesn’t receive enough light, it may extend its stems toward the available light source. This can result in longer internodes—the spaces between leaves.
If your pothos is sitting in a dark corner, behind other plants, or far away from a window, light should be the first thing you investigate.

2. Light Is Coming From Only One Direction
Even when a pothos receives enough light to survive, one-sided lighting can create uneven growth.
For example, a pothos placed beside a window may gradually lean toward the glass. The side facing the light may produce stronger growth while the opposite side becomes sparse.
Rotating the container occasionally can help distribute light more evenly.
3. The Plant Has Not Been Pruned
Pothos naturally produce trailing vines.
If you allow every vine to continue growing without pruning, the plant can eventually become long and sparse, particularly when new growth is concentrated at the ends.
Pruning helps you control the shape of the plant and gives you healthy cuttings that can be propagated.
4. Other Plants Are Blocking the Light
This is especially important in terrariums.
A pothos growing underneath taller plants may receive much less light than you realize. As the surrounding plants become larger, they can shade the pothos and encourage it to stretch.
If your pothos has suddenly become leggy after initially growing well, check whether another plant is now blocking its light.
5. Watering Problems Can Affect Growth
Watering isn’t normally the primary cause of legginess, but poor moisture management can weaken a plant and slow healthy growth.
Overwatering can damage roots, while severe underwatering can cause stress and reduce new growth.
This becomes particularly important in a terrarium because moisture can remain trapped in the growing medium and surrounding environment much longer than in a conventional houseplant pot.
How to Fix a Leggy Pothos
Once you’ve identified the problem, fixing a leggy pothos is relatively straightforward.
Step 1: Give Your Pothos Better Light
Start by improving the lighting.
Place the pothos somewhere with bright, indirect light.
You don’t necessarily need strong direct sunlight. In fact, intense direct sun through glass can cause leaf damage or excessive heat.
Instead, look for a bright location where the plant receives plenty of ambient light without being exposed to harsh afternoon sunlight for long periods.
For a terrarium, consider the position of the entire container. A terrarium sitting several feet away from a bright window may receive much less usable light than a plant sitting close to it.
If natural light is inadequate, a suitable grow light can also be useful.
Step 2: Prune the Longest Vines
After improving the lighting, prune the stretched vines.
Use clean, sharp scissors or pruning shears.
Look closely at the stem before making a cut. The small points where leaves emerge are called nodes.
Make your cut close to a healthy node.
You don’t need to remove every long vine. Focus on the sections that are particularly bare, stretched, or unattractive.
Regular pruning can also help maintain a pothos at a manageable size.
If you enjoy growing different pothos varieties, our Njoy Pothos: Ultimate Care Tips for Thriving Indoor Vines guide also covers important growing and maintenance considerations for this popular variety.
Step 3: Propagate the Healthy Cuttings
Don’t throw away healthy pieces after pruning.
Pothos are easy to propagate, and suitable cuttings can be used to produce new plants.
A cutting with at least one healthy node can potentially develop roots.
You can propagate pothos cuttings in water or an appropriate growing medium.
Once the cuttings have developed roots, you can plant them back into the original container or use them to start another pothos.
Step 4: Add Rooted Cuttings for a Fuller Plant
One of the easiest ways to make a sparse pothos look fuller is to grow several stems together.
If your original plant has only a few long vines, propagating the healthy cuttings and planting them back into the container can create growth from multiple points.
This is particularly useful when you’re trying to create a fuller terrarium display.
However, don’t overcrowd a small terrarium. Pothos can grow quickly under favorable conditions and may eventually dominate smaller plants.
Step 5: Rotate the Container
If your pothos consistently grows toward one side, rotate the container periodically.
This can help expose different parts of the plant to the main light source.
You don’t need to rotate it constantly. Occasional rotation is enough to help maintain more balanced growth.
Step 6: Check the Growing Medium
If improving the light and pruning doesn’t solve the problem, inspect the growing medium.
The roots should have access to moisture without remaining constantly saturated.
In terrariums, excess water can be particularly problematic because there is often limited drainage.
If the substrate remains extremely wet for long periods, avoid adding more water until the moisture level has dropped appropriately.
Should You Cut Off the Bare Parts?
You can cut back bare or excessively stretched sections, especially if you’re trying to reshape the plant.
However, pruning should be done strategically.
Pothos produce new growth from nodes, so cutting randomly in the middle of a long stem isn’t necessarily the best approach.
Look for healthy nodes and make your cuts accordingly.
Healthy cuttings can then be propagated and replanted.
Will a Leggy Pothos Become Bushy Again?
A leggy pothos can become much fuller, but the process takes time.
Simply cutting the plant back isn’t enough if the original cause of the legginess remains.
For example, if the pothos is stretched because it isn’t receiving enough light, cutting it back without improving the lighting can lead to another cycle of stretched growth.
A better approach is:
Improve the light → prune stretched growth → propagate healthy cuttings → encourage new growth.
For terrarium growers, maintaining the right amount of space is also important. A small container can quickly become crowded when pothos starts producing vigorous new vines.

What About Pothos in a Closed Terrarium?
Pothos can grow well in humid environments, but a closed terrarium requires careful management.
Because the container can retain moisture, you don’t need to water it as frequently as you would a conventional potted pothos.
Keep an eye on:
- Condensation
- Soil moisture
- Light levels
- Available growing space
- Vine length
- Leaf health
- Growth of neighboring plants
A closed terrarium should not remain excessively saturated.
If you see persistent heavy condensation or waterlogged substrate, the issue may be excessive moisture rather than insufficient watering.

Can a Pothos Be Too Large for a Terrarium?
Yes.
Pothos are vigorous growers, and a plant that looks perfectly sized when you first place it in a terrarium can eventually outgrow the container.
This is why pruning is especially useful for terrarium pothos.
Instead of allowing vines to grow indefinitely, trim them when they begin to overwhelm the container or shade smaller plants.
You can then propagate the cuttings or remove them from the terrarium.
The goal isn’t simply to make the pothos grow as much as possible. It’s to maintain a healthy plant that fits the scale of the terrarium.
How to Prevent Pothos From Becoming Leggy
Prevention is easier than correcting severely stretched growth.
Provide Consistent Light
Keep your pothos in a location with suitable bright, indirect light.
If natural light changes significantly throughout the year, monitor the plant’s new growth and adjust its position when necessary.
Prune Before It Gets Extremely Long
You don’t have to wait until the vines become several feet long.
Light, occasional pruning can help maintain a compact shape.
Watch New Growth
New growth is one of the best indicators of changing conditions.
If new leaves are becoming increasingly small or the distance between them is getting larger, check the lighting.
Avoid Excessive Watering
Especially in a terrarium, don’t water simply because the calendar says it’s time.
Check the growing medium and the overall humidity of the container first.
Give It Enough Space
A pothos competing with several other plants for light and space can become difficult to manage.
If the plant is beginning to dominate the terrarium, pruning or relocation may be necessary.
Common Mistakes When Fixing a Leggy Pothos
Cutting It Back Without Fixing the Light
This is one of the most common mistakes.
Pruning can temporarily improve the appearance, but insufficient light can cause the new growth to become stretched again.
Giving It Too Much Direct Sun
Moving a low-light pothos directly into intense sunlight isn’t a good solution.
Gradually improve its lighting and watch how the leaves respond.
Overwatering After Pruning
A freshly pruned plant doesn’t automatically need more water.
Continue managing moisture based on the growing conditions.
Removing Every Long Vine
Long vines aren’t automatically unhealthy.
If a vine has healthy leaves and is growing normally, there may be no reason to remove it simply because it’s long.
Prune based on the plant’s health, shape, and available space.
Frequently Asked Questions
Why is my pothos growing long vines with no leaves?
Insufficient light is one of the most common causes. The plant may be stretching toward a stronger light source. Improving the light and pruning the stretched sections can help create healthier new growth.
Should I cut back a leggy pothos?
Yes. You can prune excessively long or sparse vines, preferably making cuts near healthy nodes. The cuttings can also be propagated.
Will leaves grow back on a bare pothos stem?
New growth can develop from nodes on the remaining stem, but an existing bare section won’t necessarily fill with leaves along its entire length. Pruning and propagating cuttings can be more effective for creating a fuller plant.
Can low light make pothos leggy?
Yes. Pothos tolerate lower light, but insufficient light can encourage elongated stems and larger spaces between leaves.
Can I fix a leggy pothos without pruning?
You can improve the lighting and allow new growth to develop, but pruning is usually the quickest way to reshape an already stretched plant.
How often should I prune pothos?
There is no universal schedule. Prune when the plant becomes too long, sparse, uneven, or too large for its container.
Is pothos good for a small terrarium?
Pothos can work in some terrarium setups, but its vigorous growth means it may quickly outgrow a small container. Regular pruning is often necessary.
Final Thoughts
A leggy pothos is usually not a lost cause.
Start by looking at the light. If the plant is stretching toward a window or another light source, improve its position before doing extensive pruning.
Then trim the longest vines, propagate healthy cuttings, and replant them if you want a fuller appearance.
For terrarium-grown pothos, moisture and space are just as important. A humid environment can support healthy growth, but excessive moisture can create other problems, while a vigorous pothos can quickly overwhelm a small terrarium.
With appropriate light, sensible watering, regular pruning, and occasional propagation, you can keep your pothos healthier, fuller, and better suited to its terrarium.
