Can a Spider Plant Really Grow in Water? Here’s What You Need to Know
A spider plant can grow in water — and not just for a few weeks. With the right setup, these hardy plants can thrive in water indefinitely, sometimes for years.
Here’s a quick overview of what to expect:
- Yes, it works long-term — spider plants can live in water permanently with proper care
- Start with plantlets (spiderettes), not mature plants — they adapt much more easily
- Roots develop fast — typically within 7–14 days of being placed in water
- Weekly water changes are essential — stagnant water leads to root rot and plant death
- Add diluted liquid fertilizer — plain water alone won’t sustain a plant long-term
- Use filtered or dechlorinated water — tap water with fluoride or sodium can damage the plant
Spider plants are naturally resilient. Their thick, fleshy roots are built to hold moisture, which makes them surprisingly well-suited to life in a jar of water instead of a pot of soil.
The catch? Water growing isn’t totally hands-off. You do need to stay on top of water changes and nutrients. Skip those steps, and the plant will struggle.
But done right, it’s one of the cleanest, most low-maintenance ways to keep a living plant in your home — no soil, no mess, and no guessing when to water.
Why a Spider Plant Can Grow in Water Successfully
We often think of plants as soil-bound creatures, but the Chlorophytum comosum is a bit of a rebel. In the wild, these plants are incredibly adaptable, and that translates perfectly to hydroponic (soil-free) gardening. The secret lies in their root system. Spider plants develop thick, tuberous roots designed to store water and nutrients. When submerged, these roots adapt to pulling oxygen directly from the water.
Research shows that while soil provides a dense buffet of minerals, water offers a more streamlined environment for root initiation. In fact, many indoor gardeners find that a spider plant can grow in water with surprising vigor compared to its soil-potted cousins.
To give you a better idea of how these two methods stack up, we’ve put together a comparison based on typical growth data:
| Metric | Water Growth | Soil Growth |
|---|---|---|
| Root Development Time | 10–14 Days | 14–21 Days |
| Survival Rate (Cuttings) | 78% | 82% |
| Monthly Growth Rate | ~2.8 cm | ~3.5 cm |
| Pest Risk | Very Low | Moderate (Gnat/Mite) |
| Maintenance Level | Weekly Water Changes | Regular Watering/Repotting |
While soil-grown plants tend to get slightly larger over time due to the dense nutrient profile of the earth, water-grown plants offer a unique aesthetic and a much cleaner experience. Beyond just looking pretty, having these plants around is great for your home environment.

Benefits of the “Spider Plant Can Grow in Water” Method
Why choose water over soil? For starters, it’s a game-changer for anyone who hates the “mess” of indoor gardening. No spilled dirt on the carpet, no heavy bags of potting mix to lug around, and—perhaps most importantly—no fungus gnats. Those pesky little flies thrive in damp soil, but they can’t survive in a clean glass of water.
The aesthetic appeal is also hard to beat. Using a clear glass vessel allows us to see the intricate, white root systems as they grow, turning the plant into a living piece of art. It’s also much easier to monitor the plant’s health; if a root starts to look brown or mushy, you see it instantly, rather than waiting for the leaves to turn yellow. For busy people, it’s the ultimate “set it and forget it” (mostly) method, making them perfect Low Maintenance Air Purifying Plants for any room.
Transitioning from Soil to Water Culture
We often get asked if a mature, soil-grown spider plant can be moved into a vase of water. The short answer? It’s risky. Mature plants have spent their lives developing “soil roots,” which are structurally different from “water roots.” Dragging a mature plant out of the dirt and plopping it into water often leads to root shock, where the plant struggles to breathe and eventually rots.
If you really want to transition a mature plant, you must be incredibly thorough. Every speck of soil must be washed off the roots with room-temperature water. Even a tiny bit of leftover organic matter can trigger bacterial growth in a hydroponic setup. However, we always recommend starting with “spiderettes”—the little babies that hang from the mother plant. They are blank slates and will grow specialized water roots from day one, leading to much higher success rates. For more on general plant health, see our Essential Care Tips For Spider Plants.
Step-by-Step Guide to Propagating Spiderettes in Water
Propagating is the most rewarding part of owning a spider plant. It feels like getting a free plant every few months! To start, you’ll need to identify a healthy “spiderette.” These are the small tufts of leaves growing at the ends of the long, yellowish runners (stolons) produced by the mother plant.
- Selection: Look for a spiderette that is at least 2–3 inches long. If you look at the bottom, you might see small, bumpy “nubs.” Those are aerial roots just waiting for a drink!
- The Cut: Use a pair of sterilized scissors or a sharp knife to snip the baby plant away from the runner. Leave a tiny bit of the stem attached if you like, but the most important part is the base of the plantlet.
- Preparation: Gently rinse the base of the spiderette to ensure it’s clean.
Preparing Your Growing Vessel
The beauty of the spider plant can grow in water method is that you can use almost any container. Mason jars, vintage perfume bottles, or sleek glass vases all work beautifully.
However, there is a trick to the setup: the leaves should never sit in the water. Only the bottom of the plantlet—where the roots emerge—should be submerged. If the leaves stay wet, they will quickly turn to mush and rot.
If your jar has a wide mouth, you can use a piece of plastic wrap. Stretch it taut over the opening, secure it with a rubber band, and poke a small hole in the center. Gently tuck the base of the spiderette through the hole so it touches the water while the leaves stay high and dry. This provides excellent support and keeps the plant stable as it grows.

How to Ensure Your Spider Plant Can Grow in Water Long-Term
Can a spider plant live in water forever? Yes, but not on water alone. Water lacks the natural minerals found in soil. To keep your plant vibrant and green for years, you must provide a nutrient solution.
We recommend using a urea-free liquid fertilizer. Urea-based fertilizers are designed for soil bacteria to break down; in water, they can actually burn the roots or lead to toxic ammonia buildup. Look for a “complete” hydroponic fertilizer that includes micronutrients like iron and manganese.
Use the fertilizer at about 1/4 strength every 2–4 weeks during the growing season (spring and summer). Additionally, changing the water weekly is non-negotiable. This isn’t just about cleanliness; as water sits, it loses oxygen. Fresh water provides the “breath” your roots need to stay healthy. For a deeper dive into maintenance, our Spider Plant Care Tips has you covered.
Essential Care Requirements for Hydroponic Spider Plants
Once your spider plant is settled in its watery home, you’ll start to see white, fleshy roots filling the container. It’s a fascinating process to watch! But just because there’s no soil doesn’t mean the plant doesn’t have specific needs.
To keep your plant thriving, aim for temperatures between 65–75°F (18–24°C). Spider plants are tropical natives, so they don’t appreciate cold drafts or being placed right next to a heater. Stability is the name of the game here.
Choosing the Right Water Type
Not all water is created equal. Spider plants are notoriously sensitive to the chemicals found in municipal tap water.
- Fluoride: This is the big one. Fluoride doesn’t evaporate, and it can cause the tips of your spider plant’s leaves to turn brown and crispy.
- Chlorine: While chlorine will evaporate if you let the water sit out for 24 hours, it can still shock sensitive young roots.
- Sodium: If you have a home water softener that uses salt, do NOT use that water for your plants. Sodium is toxic to most houseplants.
For the best results, use distilled water, rainwater, or filtered water (like from a Berkey or a Brita). If you must use tap water, let it sit out overnight to reach room temperature and allow some chemicals to dissipate. You can find more advice in our Watering Tips For Indoor Plants.
Lighting and Placement for Optimal Growth
Spider plants love light, but they aren’t fans of a “sunbath.” Direct, harsh sunlight will scorch their leaves and, more importantly, will turn your water jar into an algae farm. Algae thrives on light and nutrients; if your jar is in a sunny window, the water will turn green faster than you can change it.
The “sweet spot” is bright, indirect light. North or east-facing windows are usually perfect. They provide the brightness the plant needs to photosynthesize without the heat of the afternoon sun. If you notice dust settling on the leaves, give them a gentle wipe with a damp cloth; this helps the plant “breathe” and keep its air-purifying powers at peak performance. See our guide on Cleaning Indoor Plants For Dust for the best techniques.
Troubleshooting Common Issues in Water Culture
Even with the best care, you might run into a few bumps in the road. The most common sign of trouble is yellowing leaves or brown, “mushy” tips.
Managing Algae and Root Rot
If your water looks cloudy or green, you have an algae problem. While a little algae won’t kill the plant, it competes for oxygen and nutrients. To fix this:
- Clean the vessel: Scrub the jar thoroughly with warm, soapy water.
- Rinse the roots: Gently rinse the plant’s roots under room-temperature water to remove any slime.
- Go Opaque: If algae is a recurring issue, consider using a colored glass jar or wrapping your clear jar in decorative paper to block the light from reaching the water.
Root rot is more serious. If the roots look brown, black, or feel slimy, they are rotting. This usually happens because the water wasn’t changed often enough or the leaves were submerged. Trim away any mushy roots with sterilized scissors and change the water immediately. Adding a tiny drop of hydrogen peroxide to the fresh water can help kill off remaining bacteria and add a boost of oxygen.
Identifying Nutrient Deficiencies
Because water doesn’t have the natural buffers that soil does, nutrient issues show up quickly.
- Yellowing Leaves: Often a sign of nitrogen deficiency or too much chlorine/fluoride. Ensure you are using filtered water and a balanced fertilizer.
- Stunted Growth: If your plant hasn’t grown a new leaf in months, it’s likely “hungry.” Increase your fertilizer frequency slightly, but never exceed the recommended dosage, as “fertilizer burn” is much more common in water culture.
- Brown Tips: Usually caused by low humidity or chemical sensitivity (fluoride). Try misting the plant occasionally or switching to distilled water.
Frequently Asked Questions about Water-Grown Spider Plants
Can I move a mature spider plant from soil to water?
As we mentioned, it’s possible but difficult. Mature plants often suffer from “root shock.” If you want to try, you must be surgical in your cleaning of the roots. Any leftover soil will cause the water to go stagnant and rot the plant. It is almost always better to take a cutting (a baby) from the mature plant and start fresh in water.
How often should I change the water?
Every 5 to 7 days is the gold standard. This keeps the oxygen levels high and prevents the buildup of minerals or bacteria. If the water looks cloudy before the week is up, change it sooner!
Is tap water safe for spider plants?
It depends on your local water quality. If your tap water is high in fluoride or salts, you will likely see brown leaf tips. For long-term success, distilled or rainwater is the safest bet. If you use tap, let it sit for 24 hours first.
