Your pothos plant is not growing because one or more of its essential needs aren’t being met.
If you’ve been asking why is my pothos plant not growing, the answer usually comes down to light, water, nutrients, pot size, or pests.
A pothos that isn’t growing isn’t necessarily dying, it’s just stalled.
And the good news is that most reasons your pothos plant is not growing are easy to fix once you know what to look for.
In this post, we’ll walk through the most common causes of why your pothos not growing and how to get your plant back on track.
Let’s get your pothos growing again.
Why Your Pothos Plant Is Not Growing
If your pothos plant is not growing, the first thing you need to understand is that it’s likely a simple care issue.
Pothos are famously resilient, so when growth stops, it’s a signal.
Here are the most common reasons your pothos not growing:
1. Not Enough Light Is Stalling Your Pothos Plant Growth
The number one reason why is my pothos plant not growing is insufficient light.
Pothos can survive in low light, but they won’t grow well there.
If your pothos is in a dark corner or a room with only artificial light, it simply doesn’t have enough energy to produce new leaves.
Your pothos plant is not growing because it’s diverting all its limited energy to just staying alive.
Move it to a spot with bright, indirect sunlight.
A few feet from an east or west facing window is ideal.
Once you boost the light, you’ll often see new growth within a couple of weeks.
2. Watering Issues Cause Your Pothos Plant Not to Grow
Both overwatering and underwatering can explain why your pothos not growing.
Overwatering suffocates the roots by filling the air pockets in the soil with water.
When the roots can’t breathe, they start to rot.
And rotting roots can’t deliver water and nutrients to the leaves, so the whole plant stalls.
Underwatering, on the other hand, leaves the plant too dehydrated to push out new growth.
Your pothos plant is not growing if the soil is bone dry for days at a time.
The trick is to water only when the top inch of soil feels dry to the touch.
And make sure your pot has drainage holes so excess water can escape.
3. Your Pothos Is Root Bound and Not Growing
Another common reason your pothos plant not growing is that it’s root bound.
When roots fill the entire pot and have no room to expand, they start circling around the inside of the container.
This strangles the plant and stops it from taking up water and nutrients effectively.
If you see roots poking out of the drainage holes or circling on top of the soil, your pothos needs a bigger home.
Repotting into a pot that is just one to two inches larger in diameter will give the roots fresh space.
After repotting, you’ll likely see your pothos plant growth pick right back up.
4. Lack of Nutrients Is a Reason Your Pothos Not Growing
Pothos can survive in plain water or old soil for a while, but eventually they run out of fuel.
If your pothos plant is not growing and you’ve ruled out light and water, it may be hungry.
Houseplants rely on the nutrients in their potting mix.
Over time, watering leaches those nutrients out of the soil.
Feed your pothos with a balanced, water-soluble houseplant fertilizer once a month during spring and summer.
Dilute it to half strength to avoid burning the roots.
A little food can quickly wake up a stalled pothos and get your pothos plant growth moving again.
5. Pests or Disease Slow Your Pothos Plant Growth
Sometimes the reason why is my pothos plant not growing is hiding on the undersides of the leaves.
Spider mites, mealybugs, and scale insects are tiny pests that suck sap from your plant.
This drains energy and leaves your pothos not growing at all.
Check the leaves and stems for tiny webs, sticky residue, or small cottony clusters.
If you spot pests, wipe the leaves with a damp cloth and treat with insecticidal soap or neem oil.
Once the pests are gone, your pothos plant growth can resume.
How to Get Your Pothos Plant Growing Again
Now that you know why your pothos not growing, here’s a quick checklist to get it back on schedule.
Start by increasing light exposure gradually.
Then check the soil moisture and adjust your watering routine.
If the pot feels crowded, repot into a slightly larger container with fresh potting mix.
Add a gentle fertilizer during the growing season.
And inspect for pests to make sure nothing is feeding on your plant.
Be patient after making changes.
Pothos can take a week or two to respond, but you’ll usually see a new leaf unfurling soon after you address the issue.
So, Why Is My Pothos Plant Not Growing?
Your pothos plant is not growing because something in its environment is off balance.
It’s rarely a mystery once you check the most common culprits.
If you’ve been asking why is my pothos plant not growing, look first at light, then water, then pot size, then nutrients, and finally pests.
Your pothos plant growth will bounce back as soon as you fix the underlying problem.
