Best Time to Propagate Rubber Plant

How to Propagate Rubber Plant in Water

Spring and summer are the finest times to propagate a rubber plant. The cuttings root and establish better in higher temperatures and more light.

Rooting in water takes 4–8 weeks, depending on the cutting’s size and conditions.

It’s feasible to propagate rubber plants during other seasons of the year, but the success rate may be lower and the cuttings may take longer to root. To get the best results from rubber plant propagation, wait until spring or summer.

How to Propagate Rubber Plants In Water?

Propagating a rubber plant in water is a simple and straightforward process that can be done by anyone with a healthy rubber plant and a few basic materials. Here is a step-by-step guide on how to propagate a rubber plant in water:

Select a Healthy Stem

Choose a Stem that is at least 6 inches long and has at least two or three leaves. Make sure that the stem is healthy and has no bugs or diseases.

Make a Clean Cut

Use a sharp, sterilized pair of scissors to make a clean cut just below a node (where a leaf meets the stem). Cut at a 45-degree angle to increase the surface area for rooting.

Remove The Lower Leaves

Remove any leaves from the bottom 2-3 Inches of the Stem to minimize rotting.

Fill a Jar With Water

Fill a clear glass jar with water and place the cutting inside. Make sure the bottom of the stem is fully submerged in the water.

Place The Jar In a Bright, Warm Location

Place the jar in a location that receives Bright, indirect light. The ideal temperature for rooting is between 70-75°F.

Wait For Roots To Grow

In 4-8 weeks, roots should begin to grow from the bottom of the stem. Once the roots are 1-2 inches long the cutting is ready to be planted in the soil.

It’s important to note that while propagating a rubber plant in water is relatively easy, it may take a little patience and persistence to achieve success.

Be sure to monitor the cutting regularly and provide the ideal conditions for rooting, and you should have a thriving new rubber plant in no time!

How to Choose the Best Stem-Cutting?

How To Choose The Best Stem-Cutting?

Avoid cutting random stems for propagation. Stem cutting is proper. Select a healthy rubber plant stem.

Don’t cut the plant’s healthiest stem trimming the plant short during the active season. Rubber plant propagation uses trimmed cuttings.

Leggy stems are good this avoids destroying your plant’s form. Leaf nodes are where cutting will grow roots. The stem should have two leaves.

Propagate with 6-inch stem cuttings. Covering the plant pot with plastic will cause issues with shorter or longer stems. Disease-free bright-leafed cuttings are ideal.

Gather Supplies Needed for Propagating a Rubber Plant

To propagate a rubber plant, you will need a few supplies.

These include a pair of sharp pruning shears or scissors to cut the stem or leaf, a clean container or pot with drainage holes to plant the cutting, a well-draining potting mix to promote root growth, and rooting hormone (optional).

You may also need a clear plastic bag or a propagation tray with a plastic cover to create a humid environment for the cutting.

Additionally, having a spray bottle filled with water can be helpful for misting the cutting and maintaining moisture levels.

Prepare the Container for Propagation

To prepare the container for propagating a rubber plant, follow these steps. First, choose a clean container with drainage holes that is slightly larger than the cutting you will be planting.

Next, fill the container with a well-draining potting mix, leaving some space at the top for watering. Gently press the soil to ensure it is settled. If desired, you can moisten the soil before planting.

Finally, create a small hole or indentation in the soil using your finger or a small tool, where you will place the rubber plant cutting.

Placing the Cuttings in the Water

To place the cuttings in water for propagation, follow these steps. Fill a clean glass or container with room temperature water, ensuring that the water level is sufficient to submerge the lower portion of the cuttings.

Remove any leaves from the lower end of the cuttings that would be submerged in water. Place the cuttings in the water, making sure that the bottom ends are fully submerged.

It’s important to keep the leaves above the water level to prevent rotting. Place the container in a location with indirect light and maintain the water level by adding more as needed.

Monitor the Water Levels

When propagating a rubber plant in water, it is essential to monitor the water levels. Ensure that the cuttings’ bottom ends remain submerged in water at all times, as they require constant moisture to initiate root growth.

Check the water levels regularly and add more water as needed to maintain the proper depth. It’s important to prevent the water from becoming too shallow, as this can hinder root development.

By monitoring and adjusting the water levels, you can provide an optimal environment for the cuttings to develop roots successfully.

Change the Water Regularly

If you are propagating a rubber plant within the water, it’s important to regularly change the water. This ensures that your plant has access to fresh nutrients as well as oxygen to ensure good development.

It is important to keep track of the frequency of changing the water since it will be contingent on the conditions in your room like humidity and temperature.

Here are some of the tips I’ve found useful in taking care of my rubber plant cuttings

  • Change the water every week or once every two weeks
  • Make use of filtered or distilled water in place of tap water
  • Add fertilizer liquid in 1/4 strength to every new batch of water.
  • Make sure you clean any algae build-up using an old toothbrush

It is also important to keep track of the levels of water; if they drop too low, air won’t get to the roots, which could lead to them drying out.

Troubleshooting Common Issues

In the case of propagating Rubber plants within the water, there are some typical issues you could run into.

It is essential to make sure your plant gets sufficient oxygen. Without this, the roots won’t be in a position to grow properly.

To ensure that there is adequate aeration of your water, add a few stones or gravel in the base of your container to ensure they bring air into the soil.

Keep your surroundings between 65-80°F and high levels of humidity over 60 percent. If necessary, you could also apply a humidifier to ensure the best conditions for the propagation.

With these suggestions in mind, you will be able to grow rubber plants in water swiftly and quickly!


To conclude, rubber plant stem cuttings can be propagated in water. By choosing a healthy stem cutting, trimming the lower leaves, and placing the jar in a bright, you can maximize the odds of successful propagation and establish a strong, healthy rubber plant.
