Spider plants can be grown in water.
It’s actually one of the easiest and most popular ways to propagate and display these beautiful houseplants.
If you’ve been asking yourself if spider plants can be grown in water, the answer is a definite yes, and they thrive in it for long periods when cared for properly.
Many plant lovers have successfully grown spider plants in water for months or even years with no soil at all.
In this post, we’ll explore why spider plants can be grown in water, the best methods for starting them, and how to keep them healthy in this unique growing environment.
Let’s dive into the wonderful world of water-grown spider plants.
Why Spider Plants Can Be Grown in Water
The main reason spider plants can be grown in water is their incredible adaptability and natural propagation style.
1. Spider Plants Produce Pups or Offsets Naturally
Spider plants are famous for sending out long stems that produce tiny baby plants, often called pups or offsets.
These little spiderettes already have small root nubs when they’re still attached to the mother plant.
And because spider plants can be grown in water easily, you can simply snip off a pup and place it in a jar of water.
Those tiny roots quickly develop into full water roots that thrive in a liquid environment.
2. Spider Plants Develop Water Roots Quickly
When you place a spider plant pup in water, it doesn’t take long for new roots to form.
Within a week or two, you’ll see white, fleshy roots emerging from the base of the pup.
These water roots are different from soil roots because they’re designed to absorb nutrients directly from the water.
This is why spider plants can be grown in water for extended periods without any soil at all.
3. Spider Plants Are Naturally Resilient
Spider plants are known for their tough, forgiving nature.
They tolerate low light, occasional neglect, and yes, growing in plain water.
Because spider plants can be grown in water doesn’t mean they require a lot of fussing.
They simply adapt to whatever medium you give them, including a simple glass vase or mason jar.
This resilience makes them perfect for beginners who want to try growing spider plants in water.
How to Grow Spider Plants in Water Successfully
If you’ve decided spider plants can be grown in water in your home, here’s how to set them up for the best results.
1. Start with a Healthy Spider Plant Pup
The best way to start growing spider plants in water is to use a mature pup from the mother plant.
Look for spiderettes that already have small root bumps or tiny roots showing.
Use clean scissors or pruning shears to snip the pup from the long stem.
You can also use a mature spider plant leaf division if you prefer, but pups root fastest.
2. Choose the Right Container for Water Growth
A clear glass jar, vase, or bottle works perfectly when you grow spider plants in water.
Clear containers let you see the roots develop and make it easy to check water levels.
Make sure the container is deep enough to submerge the bottom of the pup but not the leaves.
Only the base and developing roots should sit in the water to prevent rot.
3. Change the Water Regularly
To keep your spider plants healthy when grown in water, you must change the water every 5 to 7 days.
Stale water can lead to bacterial growth, which will harm the roots and turn them brown.
Use room temperature tap water that has sat out for 24 hours to let chlorine evaporate.
Or you can use filtered or distilled water for even better results.
4. Add Liquid Fertilizer Monthly
While spider plants can be grown in water for a while without fertilizer, they’ll eventually need nutrients.
Use a balanced liquid houseplant fertilizer diluted to half strength once a month during the growing season.
Add the fertilizer directly to the fresh water when you change it.
This provides essential minerals your spider plants need to stay green and produce new growth.
Common Challenges When Growing Spider Plants in Water
Even though spider plants can be grown in water, there are a few issues you might encounter.
1. Root Rot from Stagnant Water
The biggest problem with growing spider plants in water is letting the water sit too long.
If water becomes cloudy or smelly, the roots can start to rot.
Prevent this by sticking to a weekly water change schedule and rinsing the jar clean.
2. Yellow Leaves from Lack of Nutrients
If you notice leaves turning pale or yellow, your spider plant may need more food.
Remember that spider plants can be grown in water but they still need regular feeding.
Skip fertilizer during the winter months when growth naturally slows down.
3. Algae Growth in Clear Containers
Clear glass jars let in light, which can encourage algae to grow on the roots and glass.
While algae isn’t usually harmful, it can be unsightly.
Just clean the jar thoroughly when you change the water and rinse the roots gently.
You can also switch to an opaque container if algae becomes a persistent problem.
So, Can Spider Plants Be Grown in Water?
Spider plants can be grown in water, and they do it beautifully with just a little effort.
They adapt quickly, develop strong water roots, and make stunning display plants in clear vases.
Whether you’re propagating new pups or keeping a mature plant in water long-term, success is absolutely possible.
Just remember to change the water regularly, provide occasional fertilizer, and watch for signs of stress.
Growing spider plants in water is a rewarding and low-maintenance way to enjoy these classic houseplants.
