Can you propagate Selloum in water?

Answered by Douglas Hiatt

You can definitely propagate Philodendron selloum, also known as the Selloum or Tree Philodendron, in water. It is a relatively simple and effective method of propagation for this plant.

To begin, you will need to select a stem cutting that contains two or three leaves. Look for a healthy stem with no signs of disease or damage. It’s best to make a clean cut just above a nodule or aerial root, as this is where new roots will develop.

Once you have your cutting, place it in a container filled with water. Make sure at least one node is submerged in the water. You can use a clear glass or vase so that you can easily monitor the progress of root development.

Place the container in a location with bright, indirect light. Avoid direct sunlight, as it can be too harsh for the cutting. Maintain a consistent temperature of around 70-75°F (21-24°C) for optimal rooting.

Within a month or so, you should start to see roots forming from the submerged node. It’s important to change the water every few days to ensure it remains fresh and oxygenated. This helps prevent the growth of bacteria or fungi that could harm the cutting.

Once the roots have developed a decent length (around 1-2 inches), the cutting is ready for transplanting. Gently remove it from the water, being careful not to damage the delicate roots.

At this point, you have two options for transplanting: you can either pot the cutting directly into soil or continue to grow it in water for a little longer. If you choose to pot it in soil, select a well-draining potting mix and a container with drainage holes. Plant the cutting, making sure the roots are covered but the stem remains above the soil surface. Water the newly potted cutting thoroughly and place it in a location with bright, indirect light.

If you decide to keep the cutting in water for a bit longer, you can do so until the roots have further developed and grown stronger. However, it’s important to note that Selloum is not a fully aquatic plant and will eventually need to be transitioned to soil for long-term growth and health.

Propagating Philodendron selloum in water is a viable method that can result in healthy root development within a month. Once the roots have formed, the cutting can be transplanted into soil or kept in water for a short period before transitioning to soil.
