Pothos is one of the easiest houseplants to propagate in water, and the process is about as straightforward as plant care gets. You cut a stem below a node, place it in a jar of water, and wait for roots to appear. Most cuttings begin producing visible roots within one to three weeks, and the success rate is high enough that pothos has become the go-to recommendation for anyone trying water propagation for the first time. That simplicity, though, hides a handful of details that make the difference between a cutting that thrives and one that rots in the jar.
Where to Make the Cut
The single most important thing to get right is the location of your cut. Pothos roots emerge from nodes, the small bumps or brownish nubs along the stem where leaves attach. Each node contains dormant root tissue that activates when submerged in water. If you cut a stem between two nodes and leave no node on your cutting, you will get a leaf sitting in water that slowly deteriorates without ever producing roots.
A good cutting includes one or two leaves and at least one node, with roughly half an inch of bare stem below the lowest node. If the cutting has aerial roots already growing from a node, those stubby brown projections will transition into water roots faster than a bare node will. Longer cuttings with multiple nodes can work, but each node you submerge is a potential site for both rooting and rot, so keeping things simple with one or two nodes tends to give cleaner results.
Use sharp scissors or pruning shears and make a clean cut. A ragged, crushed stem absorbs water unevenly and is more prone to bacterial breakdown. Some growers let the cut end dry for an hour before placing it in water, which can help seal the wound slightly, though pothos is forgiving enough that most people skip this step without problems.
Setting Up the Jar
Any clean container that holds water works. Glass jars are popular because you can watch root development, but opaque containers have a practical advantage: they block light from reaching the water, which slows algae growth. Whichever you choose, the container should be clean. Residual soap or food residue can introduce bacteria that attack the cutting before it has a chance to root.
Fill the container with enough water to cover the node or nodes but keep the leaves above the waterline. Submerged leaves rot quickly and foul the water. Room-temperature water is ideal. Very cold water can slow root development, and hot water stresses the cutting.
Place the jar in bright, indirect light. Direct sun heats the water and accelerates algae and bacterial growth. A north- or east-facing windowsill works well. If you only have south- or west-facing windows, pull the jar back a few feet from the glass or filter the light through a sheer curtain. Pothos is famously tolerant of low light, but cuttings root faster when they get enough light to keep photosynthesizing while they build new roots.
Does Water Type Matter?
This is one of the most common questions people ask, and the answer is reassuring. A study comparing golden pothos root growth in tap water versus purified water over 22 days found no statistically significant difference between the two.1Instars: A Journal of Student Research. Golden Pothos Epipremnum aureum (Alismatales: Araceae) Root Growth in College Station Tap Water Versus Purified Water Standard municipal tap water is fine for propagating pothos. You do not need to buy distilled or filtered water for this purpose.
That said, if your tap water is heavily chlorinated, letting it sit in an open container for 24 hours before using it allows most of the free chlorine to off-gas. Chloramine, which some municipal systems use instead of chlorine, does not off-gas as readily, but pothos tolerates it at typical municipal concentrations without visible trouble. Well water with very high mineral content or water that has been run through a salt-based water softener can occasionally cause issues, but for the vast majority of households, whatever comes out of the faucet is good enough.
Why Fresh Water and Oxygen Matter
The most common mistake people make once the cutting is in the jar is forgetting about it. Water that sits undisturbed loses dissolved oxygen over time, and dissolved oxygen plays a direct role in root formation. Research on cuttings rooted in water has shown that both the timing of rooting and the number and length of roots produced respond favorably to higher oxygen concentrations in the water.2Journal of the American Society for Horticultural Science. Effects of Dissolved Oxygen Concentrations in Aero-hydroponics on the Formation and Growth of Adventitious Roots In practical terms, this means changing the water regularly, roughly every five to seven days, gives your cutting a consistent supply of fresh oxygen and washes away any accumulating bacteria or decaying organic material.
You do not need an air pump or any special equipment. Simply pouring out the old water and refilling the jar replenishes dissolved oxygen effectively. If you notice the water turning cloudy or developing an odor before the week is up, change it immediately. Cloudy water is a sign of bacterial growth, and waiting too long invites stem rot.
How Long Rooting Takes
Under typical indoor conditions, you can expect to see the first white root tips emerging from the node within seven to fourteen days. Some cuttings root faster if they already had aerial root nubs, and some take closer to three or four weeks if conditions are cooler or light is limited. Temperature has a noticeable effect: cuttings kept in rooms around 70 to 80°F tend to root faster than those in cooler spaces.
The roots will look thin and white at first, sometimes almost translucent. Over the following weeks, they branch and thicken. Most growers wait until the roots are at least two to three inches long before considering the cutting ready for soil, and letting them grow to four or five inches gives the plant a better start when transplanted. There is no rush. Pothos cuttings can stay in water for months and continue growing, which brings up a separate question entirely.
Can Pothos Live in Water Permanently?
Yes, and plenty of people keep pothos in water indefinitely as a low-maintenance way to grow the plant. A pothos vine in a jar on a kitchen counter is something of a classic for a reason: it works. The plant will continue to produce new leaves and grow in length without ever being planted in soil.
There are trade-offs, though. Growth in water is typically slower than growth in soil because the plant has limited access to nutrients. Plain water contains almost none of the minerals a plant needs to build new tissue. Over time, a water-grown pothos may produce smaller leaves, paler coloring, and thinner stems compared to a soil-grown counterpart. Adding a very dilute liquid fertilizer, roughly a quarter to a tenth of the recommended strength for soil-grown plants, every few weeks helps bridge this gap. Too much fertilizer in a water environment can burn the roots, so less is genuinely more here.
Algae can become a persistent nuisance in long-term water culture. Green film on the inside of the jar and on the roots is unsightly but generally not harmful to the plant. Using an opaque container and keeping the setup out of direct sunlight reduces algae growth substantially. Periodically rinsing the roots under running water and scrubbing the jar also helps.
Do Rooting Hormones Help?
Pothos roots so readily in plain water that rooting hormone is not necessary. However, research has tested whether biostimulants and synthetic rooting hormones can improve the process. A study on pothos stem cuttings compared several biostimulant products against TakeRoot, a common synthetic rooting hormone containing indole-3-butyric acid. One biostimulant produced the longest roots and induced root formation about 17 percent faster than the synthetic hormone, though the number of roots per cutting was not significantly different across treatments.3bioRxiv.

The takeaway for most home growers is that rooting hormone can modestly speed things up but is not a game-changer for pothos. If you already have rooting powder on hand from other propagation projects, there is no harm in dipping the cut end before placing it in water. If you do not have any, there is no compelling reason to buy it just for pothos. The plant will root on its own within a few weeks regardless.
Common Problems and How to Fix Them
Even with a plant as cooperative as pothos, things occasionally go wrong. Here are the problems you are most likely to encounter:
- Stem rot: The submerged stem turns brown, mushy, and slimy. This usually happens when the water is not changed often enough, when too much of the stem is submerged, or when a leaf is underwater and decomposing. Cut the rotted portion off above the damage, make sure a healthy node remains, and start fresh in clean water. If the rot has reached every node on the cutting, it cannot be saved.
- No roots after three weeks: Check that your cutting actually includes a node. A stem segment without a node will not produce roots no matter how long you wait. Also check the light level. Cuttings kept in very dim corners may take much longer to root or may not root at all because the leaf cannot photosynthesize enough energy to support new growth.
- Yellow leaves: A single lower leaf yellowing on a cutting is normal. The plant may sacrifice an older leaf to redirect energy toward root production. If all the leaves are yellowing, the cutting may be getting too much direct sun, the water may be stagnant, or the room may be too cold.
- Algae buildup: Green growth on the jar interior and roots. Not dangerous to the plant, but it competes for dissolved oxygen. Switch to an opaque container, change the water more frequently, and move the jar away from direct light.
Transplanting Water-Rooted Cuttings to Soil
Moving a water-rooted cutting into soil is a transition that deserves some care. Roots that develop in water are structurally different from roots that develop in soil. Water roots tend to be more delicate and less branched. They are adapted to absorbing oxygen and nutrients directly from a liquid environment, and they need time to adjust to the air pockets, microbial communities, and mechanical resistance of potting mix.
The key to a smooth transition is keeping the soil consistently moist for the first couple of weeks after planting. This mimics the water environment the roots are used to and gives them time to adapt. Use a well-draining potting mix so “moist” does not become “waterlogged,” which would suffocate the roots in a different way than water culture does. A mix with perlite or bark mixed in provides both moisture retention and air pockets.
Plant the cutting at a depth that covers all the roots and the lowest node. Water thoroughly after planting. For the first week or two, water whenever the top half inch of soil feels dry, which may be every two or three days depending on your conditions. After that, gradually let the soil dry out a bit more between waterings, training the roots to function like soil roots. Most cuttings show visible new growth within a few weeks of transplanting, which is your signal that the transition is going well.
Some growers report less transplant shock if they begin the transition gradually, adding small amounts of soil to the water jar over several days before planting. This is not strictly necessary for pothos, which handles the switch better than most plants, but it does not hurt if you want to be cautious.
Propagating Different Pothos Varieties
Pothos comes in dozens of cultivars, from the solid green Jade to the heavily variegated Marble Queen, Manjula, and the increasingly popular Global Green. All of them propagate in water using the same method. The main differences show up in speed and vigor.
Heavily variegated varieties tend to root somewhat more slowly. Variegation means less chlorophyll in the leaves, which means less photosynthetic energy available to drive root growth. A Marble Queen cutting with large white patches may take a week or two longer to root than a solid green Golden Pothos cutting of the same size. Giving variegated cuttings slightly brighter indirect light helps compensate for their reduced photosynthetic capacity.
Neon Pothos, with its chartreuse leaves, and Golden Pothos, the classic yellow-and-green variety, are among the fastest and most reliable rooters. If you are trying water propagation for the first time, starting with one of these gives you the highest odds of quick success.
Scaling Up and Sharing
One of the reasons pothos propagation is so popular is how easily it scales. A single mature vine can produce a dozen or more cuttings, and each cutting becomes an independent plant. This makes pothos a staple at plant swaps and a common gift among friends who keep houseplants.
If you want to create a fuller pot rather than a single trailing vine, root several cuttings at once and plant them together. Five or six rooted cuttings planted in a single pot will fill out much faster than a lone cutting and give you a bushy, lush-looking plant within a few months. You can also loop long cuttings back into the same pot to encourage more nodes to root and more growth points to activate.
For people who propagate regularly, keeping a dedicated propagation station with several jars in a bright spot simplifies the process. Label your jars if you are working with multiple varieties, since cuttings from different cultivars can look surprisingly similar once separated from their parent plant, especially before new leaves emerge. A Marble Queen cutting without its distinctive variegated leaf is hard to distinguish from a Jade cutting at the root stage.
