How to Propagate Pothos in Water: A Step-by-Step Guide

Pothos is one of the easiest houseplants to propagate — and water propagation is the simplest way to do it. You don’t need rooting hormone, special equipment, or much experience. A glass of water, a sharp pair of scissors, and a healthy vine are all it takes to turn one plant into many.

I’ve propagated dozens of pothos cuttings over the years, and water propagation has the highest success rate of any method I’ve tried. Here’s exactly how to do it, step by step, plus the common mistakes that trip people up.

What You’ll Need

• A healthy pothos plant with at least one vine long enough to cut
• Clean, sharp scissors or pruning shears
• A glass jar or clear container
• Room-temperature water (filtered or tap left out overnight is fine)
• A spot with bright, indirect light

That’s it. Rooting hormone is optional — pothos roots so readily in water that the University of Wisconsin Extension notes vines typically root within 3 to 4 weeks without any additives ^[1]. In fact, pothos naturally releases auxins (rooting hormones) into the water, which is why some gardeners add pothos cuttings to jars with harder-to-root plants to speed things up.

Step 1: Find the Node

This is the single most important step. The node is where roots will grow from — it’s the small brown bump on the stem, right where a leaf meets the vine. Every pothos leaf has one. If your cutting doesn’t include a node, it won’t root. Period.

Run your finger along a vine and you’ll feel them — slightly raised, sometimes with tiny aerial root nubs already poking out. Those nubs are a great sign. They’re root primordia, and they’ll develop into full roots in water much faster than a bare node.

Step 2: Make the Cut

Cut about ¼ inch below a node using clean, sharp scissors. You want a cutting that’s 4–6 inches long with 2–4 leaves ^[2]. A few things to keep in mind:

• Cut at an angle — this exposes more surface area for water uptake
• Don’t crush the stem — dull scissors compress the tissue and slow rooting. If your scissors struggle to make a clean cut, use a razor blade instead
• Take multiple cuttings — pothos tolerates heavy pruning, and having several cuttings increases your odds. I usually take 3–4 at a time and pot the best ones together later for a fuller plant

You can cut a long vine into multiple sections. Each section just needs at least one node and one leaf.

Step 3: Prepare the Cutting

Remove the bottom 1–2 leaves from your cutting so that the lower nodes are bare. These stripped nodes are what you’ll submerge — any leaves sitting underwater will rot within days and turn the water foul.

Leave at least 1–2 leaves at the top. The cutting needs foliage to photosynthesize and fuel root growth. No leaves means no energy means no roots.

Step 4: Place in Water

Drop your cuttings into a clean glass jar filled with room-temperature water. Make sure:

• At least one node is fully submerged — two is better
• No leaves are underwater — leaves in water rot and breed bacteria
• Use a clear container — you want to watch root development and spot problems early

A narrow-necked jar or bottle works well because it keeps the cutting upright without support. Wide containers work too — just lean the cutting against the rim.

Step 5: Find the Right Spot

Place your jar in bright, indirect light. A windowsill with filtered sunlight or a spot a few feet from a south-facing window is ideal. Avoid direct sun — it heats the water and promotes algae growth, and can scorch the cutting’s leaves.

Temperature matters too. Penn State Extension recommends keeping pothos at 60–80°F (15–27°C), and warmer temperatures within that range speed up rooting ^[2]. A cutting in a 75°F room will root noticeably faster than one at 65°F.

Step 6: Change the Water Weekly

This is the step most people skip — and it’s why their cuttings fail. Stagnant water becomes a breeding ground for bacteria that attack developing roots.

Change the water at least once a week. Twice a week is even better. Each time, rinse the jar and the stems to remove any slime buildup. If the water turns cloudy or develops a smell between changes, swap it immediately.

Use room-temperature water each time. Cold water shocks the cutting and can stall root growth.

Step 7: Wait for Roots (7–28 Days)

Here’s what the timeline typically looks like:

• Days 3–5: Small white bumps appear at the nodes — these are root initials
• Days 7–14: Thin white roots emerge and begin lengthening
• Days 14–21: Roots reach ½ to 1 inch and start branching
• Days 21–28: Roots are 1–2 inches long with secondary branching — ready for soil

The Wisconsin Extension notes that buds can start growing in just 1–2 weeks under warm conditions ^[1]. My experience matches this — in summer with warm room temperatures, I’ve seen roots emerge in under a week. In winter, it can take closer to three weeks.

Step 8: Transplant to Soil

Once roots are 1–2 inches long with some branching, it’s time to move to soil. Don’t wait too long — cuttings that spend months in water develop “water roots” that are fine and brittle, making the transition to soil harder.

Here’s how to transplant:

1. Fill a small pot (4-inch) with well-draining potting mix — a standard indoor mix works fine, or add a handful of perlite for extra drainage
2. Make a hole in the center deep enough for the roots
3. Gently place the cutting in and firm the soil around it
4. Water thoroughly until it drains from the bottom
5. Keep the soil consistently moist (not soggy) for the first 2 weeks while the water roots adapt to soil

The transition period is real. Your cutting might look a bit droopy for the first week as it adjusts. This is normal — the water roots need to develop soil-adapted root hairs. Keep the soil moist and resist the urge to overwater.

Common Mistakes (and How to Avoid Them)

Cutting without a node. No node, no roots. If you just snipped a leaf with a stem attached but no node, it’ll stay alive in water for weeks but never develop roots. Always check for that little brown bump.

Leaving leaves underwater. Submerged leaves rot fast, contaminate the water with bacteria, and can kill the cutting before roots develop. Strip every leaf that would sit below the waterline.

Not changing the water. Fresh water carries dissolved oxygen that developing roots need. Stagnant water becomes anaerobic and promotes rot. Weekly changes are the bare minimum.

Too much direct sun. Direct sunlight heats the water, promotes algae, and can scald leaves. Bright indirect light is what you want.

Waiting too long to transplant. Cuttings left in water for months develop fragile water-adapted roots that struggle in soil. Transplant when roots are 1–2 inches long — don’t wait for a massive root ball.

Using too-cold water. Ice-cold tap water slows root growth and can shock the cutting. Let water sit out for an hour to reach room temperature, or use filtered water.

Can You Keep Pothos in Water Forever?

Technically, yes — pothos can survive in water indefinitely. But it won’t thrive. Growth slows dramatically without soil nutrients, and the plant will eventually become leggy and pale. If you want to keep pothos in water long-term, add a few drops of liquid fertilizer (diluted to ¼ strength) to the water monthly.

For the healthiest, fullest plant, soil is always better. But a pothos cutting in a clear glass jar on a kitchen windowsill is undeniably charming — and there’s nothing wrong with keeping a few in water as decoration while you root the rest for potting.

Pro Tips for Faster Rooting

• Choose vines with aerial roots already showing. Those small brown nubs along the stem are root primordia — they’ll develop into full roots faster than bare nodes
• Propagate in spring or summer. Active growth season means faster rooting. Winter propagation works but takes 2–3x longer
• Warm water, warm room. Keep water and ambient temperature in the 70–80°F range for the fastest results
• Group multiple cuttings together. Pothos releases natural auxins into the water that may help stimulate rooting — more cuttings means more auxins
• Use a dark or amber container. If algae is a recurring problem, a dark container blocks the light that algae needs to grow while still allowing root development
