A spider plant can grow in water.
It’s true that spider plants are one of the easiest houseplants to propagate in water.
Many plant lovers ask if a spider plant can grow in water, and the short answer is yes, it absolutely can.
In fact, growing a spider plant in water is a popular method for starting new plants from the small plantlets, or “pups,” that spider plants produce.
This post will explore why a spider plant can grow in water, how to do it successfully, and what to watch out for so you can enjoy a thriving water-grown spider plant.
If you’ve been wondering whether you can keep a spider plant in water permanently, the answer is also yes with proper care.
Why a Spider Plant Can Grow in Water
Spider plants are naturally equipped to root in water.
This is because they come from a climate where they often root in damp crevices.
Let’s look at the reasons why a spider plant can grow in water so effortlessly.
1. Spider Plants Are Naturally Adaptable
Spider plants are known for their resilience.
They can thrive in a variety of conditions, including being grown in water instead of soil.
This adaptability is why a spider plant can grow in water so readily.
The roots of a spider plant can easily transition from soil to water.
Moreover, spider plants produce pups that have pre-formed root initials.
These tiny roots immediately start absorbing water and nutrients.
2. Root Development Happens Quickly in Water
When you place a spider plant pup in water, it quickly develops roots.
These roots are called water roots and they are specially adapted to absorb oxygen directly from the water.
That’s one reason why spider plants grow in water so well.
You’ll often see roots forming within a week or two.
Once established, these water roots can sustain the plant indefinitely.
3. You Can Monitor Growth Easily
Growing a spider plant in water allows you to see the root system directly.
This makes it easy to check for any issues like root rot or algae.
If you’re wondering if a spider plant can grow in water long term, many people keep them in water for months or even years.
You’ll also see new leaf growth emerge from the center.
4. The Plant Stores Energy in Its Fleshy Roots
Spider plants have thick, tuberous roots that store water and energy.
These storage roots help the plant survive when grown in water alone.
That’s another reason why spider plants grow in water so successfully.
How to Grow a Spider Plant in Water
To successfully grow a spider plant in water, follow these simple steps.
1. Start with a Healthy Pup
The best way to grow a spider plant in water is to use a pup, or baby spider plant, from the mother plant.
Make sure the pup has at least a few small roots starting.
Then simply place it in a container of water, ensuring the base of the pup is submerged but the leaves remain above water.
You can also use a stem cutting, but pups root fastest.
2. Use Clean, Non-Chlorinated Water
Spider plants can grow in water, but they prefer water that has had chlorine removed.
Let tap water sit out for 24 hours to allow chlorine to evaporate.
Alternatively, use distilled or rainwater.
Change the water every few days to keep it fresh and oxygenated.
Stagnant water can lead to root rot.
3. Provide Bright, Indirect Light
A spider plant in water needs similar light to one in soil: bright but indirect sunlight.
Avoid direct sun, which can cause algae growth in the water.
A windowsill that gets morning sun is ideal.
If the water turns green, move it to a less bright spot.
4. Add a Little Liquid Fertilizer
Since there are no nutrients in plain water, your spider plant will need feeding.
Use a balanced liquid houseplant fertilizer diluted to half strength.
Add it to the water once a month during the growing season.
This keeps your spider plant thriving in water.
What to Watch Out For When Growing a Spider Plant in Water
While growing a spider plant in water is easy, there are a few things to keep in mind.
1. Algae Can Form in the Container
If you grow a spider plant in water, algae might develop.
Clean the container and change the water regularly to prevent this.
Using an opaque container can also reduce algae growth.
Algae doesn’t hurt the plant but it can look unsightly.
2. Roots May Need Occasional Trimming
As spider plants grow in water, their roots can become long and tangled.
Trim them occasionally with clean scissors to keep the plant healthy.
Trimming also encourages new root growth.
3. Nutritional Needs Are Different in Water
In soil, spider plants get nutrients naturally.
In water, you’ll need to add a diluted liquid fertilizer every few weeks.
This ensures your spider plant continues to grow well in water.
Without fertilizer, the leaves may turn pale.
4. Root Rot is Possible in Stagnant Water
If you don’t change the water often, roots can suffocate.
Always keep the water fresh to prevent root rot.
This is crucial when you grow a spider plant in water long term.
So, Can a Spider Plant Grow in Water?
A spider plant can grow in water, and it’s a rewarding way to propagate or display this lovely houseplant.
Yes, a spider plant can grow in water as long as you provide clean water, proper light, and occasional feeding.
With minimal effort, you can enjoy a spider plant growing in water as part of your indoor garden.
So go ahead and try growing a spider plant in water – you might find it becomes one of your favorite plant projects.
Happy planting!
