Pothos is a popular houseplant that is known for its trailing vines and ease of propagation. One popular method of propagating pothos is to root cuttings in water before transplanting them into the soil. Understanding how long it takes for pothos to root in water can help gardeners plan for their plant propagation and ensure the successful growth of new pothos plants.

Requirements for Rooting Pothos in Water

Water Type

To successfully root pothos in water, it is essential to use clean, fresh water. Tap water can be used if it does not contain high levels of chlorine, which may harm the cutting. Alternatively, you can also use filtered or bottled water to ensure optimal water quality for root development. It is important to change the water every few days to prevent microbial growth and to maintain a clean environment for the roots to grow.

Container Selection

Selecting the appropriate container is critical for successful pothos propagation in water. The chosen container should be transparent, such as a glass or clear plastic jar, to allow sunlight to reach the cutting. The container should be deep enough to accommodate the submerged cutting and provide space for root development. It is also essential to ensure that no leaves are submerged in the water as this could lead to rot and hinder root growth.

Temperature Requirements

Pothos cuttings require a warm environment to root in water effectively. Ideally, the room temperature should be maintained between 65-75°F (18-24°C) for optimal growth. Placing the container in a location that receives bright, indirect light, such as near a north or east-facing window, will also facilitate root development, as direct sunlight could scorch the plant and impede growth (source).

Preparing the Pothos Cuttings

Preparing the pothos cuttings properly is essential for successful root development in water. The process involves selecting healthy cuttings and trimming the leaves to promote optimal growth.

Cutting Selection

Selecting the right cutting plays a significant role in propagating pothos plants. Look for a healthy stem with several leaves and at least 4-6 inches in length. Ensure that the stem is disease-free and has no signs of pests or damage. Cut the stem at a 45-degree angle just below a leaf node, as this is where new roots will emerge.

Trimming the Leaves

Next, trim the leaves from the lower section of the stem to expose a few inches of bare stem. Removing these leaves will prevent them from rotting in water and encourage root growth at the exposed nodes. Keep a few leaves at the top of the cutting for photosynthesis and maintaining the plant’s health during the rooting process.

Once the cuttings are prepared, place them in a container filled with clean water, ensuring that the exposed stem nodes are submerged. Change the water every 4-6 days to keep it fresh and maintain adequate oxygen levels. Proper care during this stage is crucial for successful root development, which typically takes 6 to 12 weeks, depending on the growing conditions.

Observing the Root Development Process

Pothos propagation in water is an enjoyable and fascinating experience to observe the root formation process. This section outlines the signs to look for and the typical timeframe until roots start to develop.

Signs of Root Growth

As your pothos cutting sits in water, new roots will begin to emerge from the nodes, which are the brown bumps along the stem. Keeping an eye out for these roots is crucial in determining if and when to transfer the cutting to soil. Look for tiny, white roots sprouting from the nodes, often accompanied by new leaf growth. Additionally, some changes in the water’s clarity may be seen due to the roots absorbing nutrients and releasing oxygen. It is essential to change the water every two weeks and provide indirect bright light to prevent algae formation and ensure healthy root growth(Plants Craze).

Typical Timeframe

In general, a pothos cutting takes about 7-14 days to root in water, depending on the plant’s overall health and the light source provided(Mind Body Green). The roots grow fastest during the spring and summer months due to increased sunlight-intensity, which promotes ideal growing conditions. After a cutting has rooted and the roots are over an inch long, it is usually ready for planting, a process that can take anywhere from 6 to 12 weeks in ideal conditions(Houseplant Authority).

It is important to monitor your pothos cuttings throughout the process and maintain proper care to ensure successful rooting and growth. With patience and careful observation, you can successfully propagate and grow this popular houseplant in water.

Transitioning to Soil (Optional)

If you’ve propagated your pothos in water and would like to transition it to soil, this section outlines the steps to make it a smooth change.

Preparing the Soil

Before planting your pothos cutting into soil, you need to prepare a suitable potting medium. A well-draining soil mix is essential, as pothos plants don’t enjoy sitting in soggy soil. You can prepare a mix of equal parts peat moss, perlite, and potting soil. Alternatively, buy a pre-mixed potting soil designed for houseplants.

Ensure the chosen pot has drainage holes to prevent water from accumulating at the bottom. Fill the pot with the prepared potting mix and dampen it evenly with water.

Planting the Rooted Pothos

Once the roots have reached at least 2 inches (5 centimeters) long (usually after 6 to 8 weeks), your pothos cutting is ready for planting. Gently remove the cutting from the water, taking care not to damage the delicate roots.

Once removed, make a hole in the potting mix, deep enough to accommodate the developed roots. Place the cutting in the hole, ensuring the roots are fully covered by the soil. Gently tamp the soil around the cutting to secure it in place.

Water the newly planted pothos thoroughly and let the excess water drain for about 30 minutes. Place the pot in a well-lit area, but avoid direct sunlight. Pothos plants thrive in bright, indirect light.

Keep an eye on the moisture level in the soil, avoiding over-watering or allowing it to dry out completely. Within a few weeks, your pothos plant should start showing new growth and acclimate to its new soil environment.
