Best Way to Propagate Pothos in Water: A Simple Guide

Why Water Propagation Is the Best Way to Propagate Pothos

If you've ever wanted to multiply your pothos collection without spending a dime, water propagation is your new best friend. Pothos (Epipremnum aureum) is one of the easiest houseplants to propagate, and doing it in water lets you watch the magic happen in real time. No guessing whether roots are forming — you can literally see them grow!

Whether you're a first-time plant parent or a seasoned green thumb, this method is reliable, low-cost, and endlessly satisfying. Let's walk through everything you need to know to do it right.

What You'll Need Before You Start

The good news? You don't need any fancy equipment. Here's your simple supply list:

A healthy pothos plant with long vines
Clean scissors or pruning shears (sterilize with rubbing alcohol)
A glass jar or vase — clear works best so you can monitor root growth
Room-temperature water (filtered or tap water left out overnight to off-gas chlorine)
Optional: Liquid rooting hormone to speed things up

Step-by-Step: The Best Way to Propagate Pothos in Water

Step 1: Choose the Right Cutting

Success starts with picking the right stem. Look for a healthy vine with at least two to three nodes — those small brown bumps or nubs along the stem where leaves and roots emerge. Without a node, your cutting simply won't root, so this step is non-negotiable.

Aim for a cutting that's about 4 to 6 inches long. Avoid stems that look yellow, mushy, or pest-damaged. If you're not sure what a healthy cutting looks like, check out our complete pothos care guide to get familiar with the plant's anatomy.

Step 2: Prepare Your Cutting

Once you've selected your stem, make a clean cut just below a node using your sterilized scissors. A clean cut reduces the risk of disease and helps the stem callous properly.

Next, remove any leaves that would sit below the waterline. Submerged leaves rot quickly and can introduce bacteria into your water, which may harm your developing roots. Leave two or three leaves at the top of the cutting to support photosynthesis.

Step 3: Place the Cutting in Water

Place your prepared cutting into your jar so that at least one or two nodes are submerged but the remaining leaves stay above the waterline. A clear glass jar is ideal because it lets light in and allows you to check root progress without disturbing the cutting.

Position the jar in a spot with bright, indirect light. A windowsill that gets filtered light is perfect. Avoid direct sunlight, which can cause algae to bloom in the water and potentially stress your cutting.

Step 4: Change the Water Regularly

This step is where many beginners go wrong. Fresh water is essential for healthy root development. Change the water every five to seven days, or sooner if it starts to look cloudy or smells off. Each time you change the water, give the jar a quick rinse to prevent algae and bacterial buildup.

Using room-temperature water is important — cold water can shock the cutting and slow root growth. If you're using tap water, letting it sit in an open container for 24 hours allows chlorine to evaporate, making it gentler on your plant.

Step 5: Wait and Watch

Patience is key! Most pothos cuttings will begin showing visible roots within 1 to 4 weeks, depending on the season, light levels, and the health of the original plant. Roots tend to develop faster in warmer months when the plant's growth is naturally more active.

You'll first notice small white nubs emerging from the nodes. Over the following weeks, these will grow into longer, string-like roots. Once your roots are at least 1 to 2 inches long, your cutting is ready to be potted up in soil — or you can keep it growing in water indefinitely if you prefer!

Tips to Speed Up Pothos Root Growth in Water

Add a small amount of liquid rooting hormone to the water to encourage faster root development.
Keep temperatures warm — pothos root best between 65°F and 85°F (18°C–29°C).
Use a narrow-necked jar to keep the cutting stable and ensure nodes stay submerged.
Propagate in spring or summer when the plant is in its active growing phase.
Avoid overhandling — checking on your cuttings too frequently can disturb developing roots.

Common Pothos Propagation Mistakes to Avoid

Cutting Without a Node

This is the number one mistake new propagators make. A cutting without a node will never produce roots, no matter how long you wait. Always double-check that your cutting includes at least one node before placing it in water.

Leaving Too Many Leaves Underwater

Submerged leaves decay rapidly and create a breeding ground for harmful bacteria. Always strip any leaves that fall below the waterline, and keep the jar clean with regular water changes.

Placing Cuttings in Direct Sunlight

While pothos loves light, direct sun on a water-filled jar creates a greenhouse effect that can overheat your cutting and encourage algae growth. Stick to bright, indirect light for the best results.

When to Transfer Your Pothos to Soil

Once your roots reach 1 to 2 inches in length, it's time to consider transitioning to soil. Choose a well-draining quality potting mix and a pot with pots with drainage holes. Water your newly potted cutting thoroughly and place it in bright, indirect light.

Keep in mind that roots grown in water are structurally different from soil roots, so your pothos may experience a brief adjustment period. Don't panic if a leaf or two droops — it's completely normal and your plant will bounce back within a week or two. For help with the next steps, explore our guide on pothos soil and repotting.

Can You Keep Pothos in Water Permanently?

Absolutely! Many plant lovers choose to grow their pothos in water long-term, and it can thrive beautifully with proper care. If you go this route, use a diluted liquid balanced liquid fertilizer every four to six weeks to provide the nutrients your plant would normally get from soil. You can learn more about this approach in our article on growing pothos in water permanently.

Final Thoughts

The best way to propagate pothos in water comes down to three things: a healthy cutting with a node, clean water, and a little patience. It's one of the most beginner-friendly plant projects you can try, and the reward — a brand-new pothos to keep, gift, or trade — makes it absolutely worth it.

Frequently Asked Questions

How do you propagate pothos in water?

Cut a healthy 4-6 inch stem just below a node, remove leaves that would sit underwater, and place it in a clear jar so at least one or two nodes are submerged. Keep it in bright, indirect light and change the water every 5-7 days.

What do you need to propagate pothos in water?

You only need a healthy pothos cutting, sterilized scissors, a clear glass jar, and room-temperature water. Liquid rooting hormone is optional but can speed up root development.

How long does a pothos cutting need to be for water propagation?

Aim for a cutting that is 4 to 6 inches long and includes at least two to three nodes, which are the small brown bumps along the stem where roots will emerge.

How often should you change the water when propagating pothos?

Change the water every 5-7 days, or sooner if it looks cloudy or smells off. Always use room-temperature water to avoid shocking the cutting and slowing root growth.

Where should you put pothos cuttings when propagating in water?

Place the jar in a spot with bright, indirect light, such as a windowsill with filtered light. Avoid direct sunlight, as it can cause algae growth and stress the cutting.
