Can Pothos Grow Fully Submerged

Pothos can grow fully submerged in water.
 
But there’s more to it than just dropping a cutting in a tank and hoping for the best.
 
If you’ve been wondering can pothos grow fully submerged, the short answer is yes, but with some important conditions.
 
Many aquarium enthusiasts successfully grow pothos fully submerged in freshwater setups.
 
However, not every pothos variety will thrive when completely underwater.
 
In this post, we’ll explore why pothos can grow fully submerged, the best practices for doing so, and common pitfalls to avoid.
 
Let’s dive deep into growing pothos fully submerged.
 

Why Pothos Can Grow Fully Submerged

Pothos can grow fully submerged because of their natural ability to adapt to wet environments.
 
Here are the key reasons why growing pothos fully submerged is possible:
 

1. Pothos Are Semi-Aquatic by Nature

Pothos originate from tropical rainforests where they grow along riverbanks and in flooded areas.
 
Their roots are used to being constantly wet or even underwater.
 
This semi-aquatic adaptation is what allows pothos to grow fully submerged for extended periods.
 
In fact, in the wild, pothos often send roots into streams and ponds.
 
So when you ask can pothos grow fully submerged, their biology says yes.
 

2. Aerial Roots Work Underwater

Pothos have specialized aerial roots that absorb moisture and nutrients from the air.
 
When fully submerged, these roots switch to absorbing oxygen and nutrients directly from the water.
 
This flexibility is a huge reason why pothos can grow fully submerged.
 
The roots don’t rot easily in clean water, especially if the water is well-oxygenated.
 
So growing pothos fully submerged is just a matter of giving them the right water conditions.
 

3. They Tolerate Low Light Underwater

Pothos are famous for thriving in low-light indoor spaces.
 
This shade tolerance carries over when pothos grow fully submerged.
 
Aquarium lights or indirect sunlight are usually enough for pothos to photosynthesize underwater.
 
But if you keep pothos fully submerged in dim water, growth will slow dramatically.
 
Still, the plant won’t die quickly, which proves how resilient they are.
 

How to Successfully Grow Pothos Fully Submerged

Now that you know pothos can grow fully submerged, let’s talk about how to make it work.
 
Here are the best practices for growing pothos fully submerged:
 

1. Start with a Healthy Cutting

Choose a pothos cutting that has at least two or three leaves and a node.
 
The node is where new roots will emerge underwater.
 
Let the cutting root in water first for a week or two before fully submerging it.
 
This transition helps the plant adjust to being completely underwater.
 
A healthy cutting is key when you want pothos to grow fully submerged.
 

2. Use Oxygen-Rich Water

Stagnant water can cause root rot even for pothos that can grow fully submerged.
 
In an aquarium, the water movement from filters or air stones provides oxygen.
 
If you’re growing pothos fully submerged in a jar or vase, change the water every week.
 
This prevents bacteria buildup and keeps the roots healthy.
 
Oxygen is essential for pothos to grow fully submerged long-term.
 

3. Provide Adequate Light

While pothos tolerate low light, they grow best submerged under moderate aquarium lighting.
 
Place the pothos near a window or use a grow light if you’re growing pothos fully submerged indoors.
 
Without enough light, the leaves may yellow or drop off.
 
But with proper lighting, pothos can grow fully submerged and even produce new leaves underwater.
 

Challenges of Growing Pothos Fully Submerged

Even though pothos can grow fully submerged, there are some challenges you should know.
 
Here are common issues and how to handle them:
 

1. Leaf Melting

When pothos grow fully submerged, some older leaves may turn mushy or translucent.
 
This is called melting, and it happens as the plant adapts to underwater conditions.
 
Remove any dying leaves to prevent them from clouding the water.
 
New leaves that grow underwater are usually more durable.
 

2. Algae Growth

Pothos roots and leaves can attract algae when growing pothos fully submerged.
 
Algae thrive on the nutrients in the water and on the plant surfaces.
 
Control algae by limiting light duration and keeping the water clean.
 
Adding algae-eating fish or snails can also help when pothos grow fully submerged.
 

3. Slower Growth Rate

Compared to pothos grown in soil or with roots in water but leaves above, fully submerged pothos grow slower.
 
This is because underwater, carbon dioxide is less available for photosynthesis.
 
You can boost growth with liquid fertilizers designed for aquariums.
 
But don’t expect your pothos to grow fully submerged as fast as their terrestrial cousins.
 

So, Can Pothos Grow Fully Submerged?

Pothos can grow fully submerged, but it takes a bit of care and patience.
 
We’ve covered why pothos can grow fully submerged, how to set them up, and what challenges to watch for.
 
Start with a healthy cutting and provide oxygenated water and moderate light.
 
Monitor for leaf melt and slow growth, and adjust as needed.
 
With the right conditions, pothos can grow fully submerged and even become a beautiful part of your aquarium or underwater garden.
 
Hope this guide helps you succeed in growing pothos fully submerged.
