Pothos propagation is an easy and popular method of growing new plants from cuttings in water. But how often should you change the water in your pothos propagation vessel? In this article, we’ll explore the answer to that question and provide you with helpful tips for successful pothos propagation.

What Is Pothos Propagation

Pothos propagation is the process of multiplying pothos plants through cuttings from an existing, healthy plant. Pothos (Epipremnum aureum) is a popular houseplant known for its easy care needs and quick growth. By employing the right method, anyone can propagate pothos plants and expand their indoor garden.

There are two main methods for propagating pothos: water and soil propagation. Water propagation is the most common and beginner-friendly method. In this method, pothos cuttings containing one or more nodes are placed in a container with clean water. Over time, roots will develop from the nodes and eventually, the cutting can be planted in soil.

While water propagation is popular, soil propagation is also an option. In this method, the cuttings are placed directly into a well-draining soil mix to encourage root growth. Both methods can yield successful results, but it is essential to maintain proper conditions such as temperature, humidity, and light, to allow the cuttings to thrive and grow.

When propagating pothos in water, it is crucial to change the water regularly to ensure the health of the developing roots. Experts recommend changing the water every 5 to 7 days to prevent bacteria, algae buildup, and debris from hampering root growth. Proper water hygiene is crucial to help the cuttings develop a strong and healthy root system, ensuring the future success of your propagated pothos plants.

Methods of Pothos Propagation

There are several popular methods for propagating pothos plants, each with its own benefits and conditions for successful growth. In this section, we will explore three common methods: water propagation, soil propagation, and sphagnum moss propagation.

Water Propagation

Water propagation is a popular choice for beginner gardeners due to its simplicity and effectiveness. To propagate pothos in water, follow these steps:

  1. Take 4-6″ length cuttings from a healthy parent plant, ensuring each cutting has at least one node.
  2. Remove any lower leaves near the cut end, leaving only a few leaves on the top.
  3. Place the cuttings in a container filled with clean, room-temperature water, making sure the node is submerged.
  4. Put the container in a bright spot with indirect sunlight.
  5. Change the water once a week to keep it fresh and prevent microbial growth1.

Roots should begin to grow from the nodes within a couple of weeks. Once they reach 2-3 inches in length, the cuttings can be transplanted to soil or another propagation medium.

Soil Propagation

Soil propagation is also an effective method for pothos growth. To propagate pothos directly in soil, follow these steps:

  1. Prepare a small pot with fresh potting soil, making sure it’s well-draining.
  2. Take cuttings similar to the water propagation method, but dip the cut ends in rooting hormone to encourage faster root development.
  3. Create small holes in the soil with a chopstick or pencil, ensuring they are deep enough to cover the node on each cutting.
  4. Place the cuttings in the holes and gently press the soil around them to hold them in place.
  5. Water the soil thoroughly and keep it consistently moist throughout the propagation process2.

In 3-8 weeks, cuttings should develop a healthy root system, ready for transplanting into larger pots if desired.

Sphagnum Moss Propagation

Sphagnum moss propagation offers an alternative to water and soil methods. With higher humidity and air circulation, this method can be beneficial for root growth. To propagate pothos in sphagnum moss, follow these steps:

  1. Hydrate a portion of sphagnum moss by soaking it in water, then wring out excess moisture.
  2. Take cuttings like in the water and soil propagation methods; dip the cut ends in rooting hormone.
  3. Wrap the hydrated sphagnum moss around the cut end of the cutting, covering the node.
  4. Secure the moss in place using a twist tie or similar material.
  5. Place the wrapped cuttings in a clear plastic bag, ensuring there is room for air circulation.
  6. Keep the bag in a bright spot with indirect sunlight and maintain moisture within the sphagnum moss3.

After a few weeks, the cuttings should have developed roots within the moss. They can be transplanted into the preferred medium, such as soil or a potting mix, for continued growth.

Frequency of Water Change in Water Propagation

Pothos propagation is a popular and effective method to grow this easy-care plant in water. To ensure healthy growth during this process, focusing on the frequency of water change is crucial.

When propagating pothos in water, it is essential to replace the water every few days to maintain optimal conditions for the plant’s growth (source). If the water appears clear and free of debris, topping it up is also an option. Using filtered water is often the best choice, as tap water can contain salts and minerals that may potentially shock the plant.

Aside from maintaining appropriate water levels, it is also important to change the water every one to two weeks to ensure the plant has sufficient oxygen (source). Oxygen levels in the water are vital for the plant’s overall health and root development. Consistently refreshing the water helps prevent stagnation and promotes ideal conditions for growth.

In addition to changing water regularly, pothos plants require some fertilization when grown in water. Fertilize the pothos plant every 4 to 6 weeks to provide essential nutrients for its growth (source). Following the instructions on the fertilizer packaging is crucial, as over-fertilizing can harm the plant.

In summary, changing the water in pothos propagation at regular intervals, along with appropriate fertilization, ensures a healthy environment and promotes successful growth. Remember to monitor water conditions closely and adjust accordingly while the pothos plant transitions from a cutting to a rooted, thriving plant.

Signs It’s Time to Change Water

Cloudy or Murky Water

One of the primary indications that it’s time to change the water when propagating pothos is cloudy or murky water. This often signals the presence of bacteria or other contaminants that can impede the plant’s growth and might even lead to rotting. Typically, it’s recommended to replace the water every 3-5 days or when you notice that the water has become cloudy.

Foul Smell

Another sign that it’s time to change the water is if you begin to detect a foul smell emanating from the container or jar. This can be indicative of bacterial or fungal growth in the water, which can negatively impact the health of your pothos cutting. It’s crucial to keep the water fresh and clean by changing it at least every 2-3 days. This ensures that the roots have access to the necessary nutrients and remain healthy.

Algae Growth

If you notice green, slimy growth on the surface of the water or along the sides of the container, this is a sign of algae growth. Algae can compete with the pothos for vital nutrients in the water and may impede rooting. To prevent algae growth, place your container in a brightly lit spot that does not receive direct sunlight, as suggested on Gardening Stack Exchange. Sunlight can accelerate algae growth, so avoid placing the container in areas with excessive sunlight. Along with proper placement, change the water regularly to keep the environment ideal for rooting.

By being vigilant about water quality and changing the water timely when propagating pothos, you can ensure the best possible conditions for healthy growth and successful rooting.

Tips for Successful Water Propagation

Choose Healthy Cuttings

Begin by selecting healthy cuttings from your pothos plant, as they will have a higher success rate. Ideally, choose a stem that is around 4-6 inches long with at least three healthy leaves. Remove the leaves from the bottom part of the cutting, leaving only the top two or three. This will encourage root growth from the nodes where leaves were removed.

Use Filtered Water

For the best results, use filtered water when propagating pothos in water. This will reduce the potential for contaminants that may hinder growth. Fill a jar, vase, or container with enough water to cover the nodes, but not the leaves, and place the cuttings in the water. To maintain a healthy environment, change the water every one to two weeks, as this helps prevent the buildup of microbes that may affect growth 1. Additionally, you can use a liquid fertilizer to ensure proper nutrients for strong growth 2.

Provide Adequate Light

Pothos cuttings require 6 to 8 hours of bright, indirect light daily for successful propagation 3. Keep the container with the cuttings in a warm, well-lit location where they will receive consistent light. Avoid direct sunlight, as this can damage the leaves and hinder growth.

During the propagation process, be patient; it can take around four to six weeks for the cuttings to produce roots from the nodes 4. Once the roots are at least 2 to 3 inches long, the cuttings can be transferred from water to soil 5. Remember to always provide the newly-rooted pothos plant with adequate light, warmth, and moisture.

Transitioning to Soil

When propagating pothos in water, it is essential to change the water once a week to ensure adequate oxygenation, which aids in successful root growth. However, once the roots have reached a length of around 2 to 3 inches, it is time to transition the cuttings to soil for continued growth and long-term stability.

Prior to planting the rooted cuttings, gently rinse the roots under tepid water to remove any unwanted debris or potential pests that may have found their way into the water-filled container. Next, prepare a pot with well-draining soil, ensuring that it has a drainage hole to prevent waterlogged conditions.

Carefully insert the root system of each cutting into the soil, burying the roots to promote stability and adequate anchorage as the plant matures. Provide a stake or supporting structure if needed to help the pothos establish itself in its new medium. After planting, water the soil evenly until water begins to emerge from the drainage hole, indicating thorough moisture penetration.

Place the pot containing the newly transitioned pothos in a warm, bright room, avoiding direct sunlight to prevent shock. Maintain consistently moist soil, but avoid overwatering, as pothos prefers a slightly drier environment. Monitor the plant for any signs of stress, such as wilting or dropping leaves, and adjust care as necessary.

In 3-4 weeks, gently tug on the cuttings to assess root establishment. If resistance is encountered, it signifies that the pothos has successfully taken root in the soil and can continue to grow and thrive. With time and proper care, the transitioned pothos will flourish, exhibiting the lush foliage and trailing growth characteristic of this popular houseplant.
