How to Propagate Pothos in Water [2023 - Ultimate Guide]

This ultimate guide will walk you through the step-by-step process of propagating pothos in water, ensuring that you have success with your propagation endeavors.

Why it matters: If you're a plant lover looking to expand your green thumb, propagating pothos in water is a fantastic way to multiply your plant collection for free.

Key takeaways:

1. Where to cut: Cut your Pothos just below the leaf node, where the leaf meets the stem. This allows new roots to develop.
2. How long it takes: It usually takes 3-6 weeks for pothos cuttings to develop roots in water. You can speed up propagation by giving your propagates more sunlight and humidity, or using rooting hormone.
3. How many leaves are required: Each cutting should have 3-4 leaves. More leaves mean more energy for root growth. Too few leaves may not be enough.

Step-by-Step Guide to Propagate Pothos in Water

Step 1: Gather the Essential Supplies

Having the right tools and supplies is crucial for successful pothos propagation. You'll need:

1. A clean, sharp pair of pruning shears
2. A glass jar or container with a wide opening
3. Water to fill the jar
4. An area with bright, indirect sunlight like a windowsill or table near a window

Step 2: Take cuttings from the Pothos plant

Proper trimming promotes new growth and keeps pothos vibrant. 

Before you trim:

1. Examine the plant and identify healthy stems with 3-4 leaves
2. Ensure pruning shears are clean and sharp
3. Have a container of water ready

When taking cuttings:

1. Cut just below the leaf node
2. Use sharp shears for clean cuts
3. Place cuttings directly in water
4. Change water regularly

Using the pruning shears, position them just below a leaf node. A leaf node is the point where a leaf connects to the stem. By cutting just below this node, you are providing the plant with the opportunity to develop new roots.

It's crucial to use sharp pruning shears for this task. Dull shears can cause damage to the plant, leading to slower healing and potential diseases. Before making each cut, ensure that the blades are clean and sharp. You can wipe them with a clean cloth or paper towel to remove any dirt or debris.

Submerge the Stem Cuttings in Water for 3-6 Weeks

After you have taken cuttings from your pothos plant, it's time to propagate the stem cuttings in water. 

Place the cuttings in the glass or jar filled with water, ensuring that at least two nodes are submerged. Nodes are the bumpy parts on the stem where the leaves are attached.

By placing the cuttings in water, the adventitious roots on the pothos are encouraged to grow. The water acts as a medium for root development.

It's important to keep the leaves above the waterline to prevent them from rotting. You may use small rocks or stakes to support the cuttings if needed. Arrange multiple cuttings in the same vessel to make the most of your propagation efforts.

Change the Water Regularly

To ensure a healthy propagation process, it's essential to change the water regularly. Every five to seven days, replace the water in the glass or jar to prevent bacterial growth and maintain ideal conditions for root development.

When changing the water, be careful not to disturb the delicate roots that are starting to form. Handle the cuttings gently and with care to avoid any unnecessary stress.

Monitor the Root Growth

Over time (typically in 4 - 8 weeks, sometimes as soon as 2 weeks), you will start to see tiny roots emerging from the nodes of the stem cuttings. This is a positive sign of successful propagation. As the roots grow longer and thicker, they indicate that your pothos cuttings are establishing a strong foundation.

Patience is key during this stage, as root growth can vary depending on environmental conditions and individual plants. Maintain a consistent watering routine and keep an eye on the progress to ensure optimal root development.

How to Speed Up Propagation

There are methods to potentially speed up propagation. One technique is to use rooting hormone on the cuttings before placing them in water, which can help stimulate faster root growth. 

Additionally, maintaining optimal conditions such as providing adequate light, warmth, and humidity can contribute to quicker propagation. Remember to keep the water sterile, changing it every day or two and adding a few drops of bleach if you're away.

Re-Pot the Plant When Ready

Once the roots have grown to a few inches in length, it's time to re-pot your propagated pothos. Choose a suitable pot with well-draining soil that is rich in organic matter. Make a small hole in the soil and gently place the rooted cutting, ensuring the roots are covered but the leaves remain above the soil surface.

Water the newly potted plant thoroughly and place it in a well-lit area. As your pothos continues to grow, you'll soon witness the beautiful transformation of a single cutting into a lush and healthy plant.

Use Proper Soil and Fertilizer

Once your propagated pothos is potted, it's crucial to provide it with the right soil and occasional fertilization. Pothos prefers well-draining soil that retains some moisture, allowing the roots to breathe without becoming waterlogged.

Use a high-quality potting mix that contains a blend of peat moss, perlite, and compost to create a nutritious environment for your plant's roots to thrive. To further promote growth, use a balanced liquid fertilizer once a month during the growing season.

Ensure the Plant Receives Adequate Sunlight

Adequate sunlight is essential for the healthy growth of your pothos. Place your plant in a location where it can receive bright, indirect sunlight. Avoid exposing the plant to direct sunlight, as it can scorch the leaves and hinder growth.

If you don't have a suitable spot with indirect sunlight, you can also use artificial grow lights to provide the necessary light energy for your pothos to flourish.

Water Adequately

Because the Pothos plants’ roots are less developed, the plant will be able to absorb less water from the soil and will need to be watered more frequently than a mature plant.

Combat Common Pothos Growing Issues

Although pothos is generally a hardy plant, it can encounter a few growing issues. Overwatering, underwatering, pests, and temperature extremes are some common problems you may face.

To combat these issues, always be mindful of your watering habits, ensuring the soil is evenly moist but not waterlogged. Regularly inspect your plant's leaves for any signs of pests, such as spider mites or mealybugs, and take prompt action if necessary.

Additionally, maintain a consistent temperature range between 60-80°F (15-26°C) to provide a comfortable environment for your pothos to thrive.
