How to Propagate a Rubber Plant


Rubber plants, known scientifically as Ficus elastica robusta, are a favorite among houseplant enthusiasts due to their large, glossy leaves and vigorous growth. Propagating rubber trees is an enjoyable way to expand your indoor garden and share new plants with friends. Unlike the fiddle leaf fig, which is also popular for its decorative appeal, rubber plants are easier to propagate and maintain. Their adaptability to a range of indoor conditions makes them a versatile choice for indoor plants. Ensure that the soil is kept consistently moist but not wet to promote healthy growth.

This comprehensive guide will take you through the steps of propagating a rubber plant tree. Ficus elastica plants flourish with adequate light, which boosts their growth and vitality.

Why Propagate Rubber Plants?

There are numerous benefits to propagating rubber plants. It allows you to grow new plants from a healthy rubber tree, filling your home with lush greenery. Propagation can also rejuvenate an aging rubber plant tree, promoting new growth and vitality. As with most indoor plants, propagating rubber tree plants helps maintain their size and shape, making them easier to manage in a home environment.

Rubber plants are highly adaptable, whether planted directly in soil or placed in a suitable medium. They can thrive in a variety of growing conditions, even in low-light environments where other plants may struggle. Known for their deep green leaves, some varieties also feature striking dark green foliage that adds a beautiful contrast to any indoor garden.

Necessary Tools and Materials

Before you start, gather the following tools and materials:

  • A healthy rubber tree plant
  • Sharp pruning shears
  • Clean pots and containers
  • Potting mix
  • Rooting hormone (optional)
  • Plastic wrap
  • Damp cloth
  • Pack damp moss

    Preparing the Rubber Plant

    Begin by selecting a healthy Ficus elastica houseplant for indoors. Look for a mature rubber tree with robust growth and no signs of disease or pests. Ensure the plant is well-hydrated before starting the propagation process. This will encourage new leaves and help the plant thrive when exposed to more light. Be mindful that the rubber tree's leathery leaves can turn yellow if the plant is overwatered or exposed to poor conditions. Consistent care and the right conditions indoors will help prevent this and keep your plant thriving.

    Method 1: Propagation by Cuttings

    Step 1: Selecting a Cutting

    Choose a branch from your rubber fig tree that has at least two or three leaves. Using sharp pruning shears, cut a 6-inch section just below a node, where the leaf meets the stem. You may need to prune a bit to get a clean cut and ensure the cutting is healthy for propagation of trees. Be sure to avoid branches with brown spots, as this could indicate disease or pest issues.

    Step 2: Preparing the Cutting

    Remove the lower leaves of the rubber tree, leaving a few at the top. If desired, dip the cut end into rooting hormone to encourage faster root development.

    Step 3: Planting the Cutting

    Fill a small pot with a well-draining potting mix. Make a hole in the center and insert the cutting, ensuring the cut end is buried. Firmly press the soil around the cutting to support it. Plant the cutting during the growing season, ideally in the summer, when it is more likely to root successfully and grow quickly.

    Step 4: Creating a Humid Environment

    Cover the pot with plastic wrap to create a mini-greenhouse effect, maintaining high humidity. Place the pot in bright light but avoid direct sunlight, which can scorch the leaves. Ensure the plant is stable by reusing the previous pot if it has sufficient drainage. This method works well for houseplants, as it creates a controlled environment for optimal growth, ensuring a healthy rubber tree.

    Keep an eye on the leaves; if they start turning yellow, it might indicate stress or improper care. Adjust the environment and care routine accordingly to promote healthy growth.

    Method 2: Propagation by Air Layering

    Step 1: Selecting a Branch

    Choose a healthy branch on your rubber tree plant. This method works best on more mature plants with thicker stems. Ensure the plant reaches an appropriate size before propagation to increase success rates.

    Propagate during the spring when the plant is actively growing. Protect the plant from cold drafts, as sudden temperature changes can stress it and hinder root development.

    Step 2: Making the Cut

    Make a small cut about one-third through the stem, just below a node. Insert a small stick or toothpick into the cut to keep it open. Ensure your fingers are clean to avoid introducing any bacteria into the cut. Under the right conditions, roots should begin to develop, typically observed in the fall when the plant's growth is more active. This method helps in propagating a healthy rubber tree.

    Step 3: Applying Moss

    Wrap the cut area of the rubber tree plant with damp moss and secure it with plastic wrap. Ensure the moss stays moist by regularly checking and re-wetting as necessary to support healthy leaf growth.

    To keep the area clean, gently dust the surrounding leaves with a damp cloth. Place the prepared cutting in a suitable container to maintain humidity and encourage root growth.

    Step 4: Waiting for Roots

    Roots should begin to form within a few weeks. Once a good number of roots have developed, cut the branch below the rooted section and pot it in a suitable potting mix. If a leaf fell during the process, don't worry, as the growing tip will continue to develop and produce new leaves over time.

    Caring for New Rubber Plants

    Light and Placement

    This mature plant thrives in bright light but should be protected from direct sunlight. A sheer curtain can help filter intense light, providing the perfect environment for your new houseplants. Ensure it receives indirect sunlight to prevent leaf scorching and promote healthy growth. This care will help your rubber tree thrive.

    Watering and Humidity

    Maintain a regular watering routine for your rubber tree, keeping the soil consistently moist but not waterlogged to ensure a healthy moisture level. High humidity levels are beneficial, so consider misting the leaves or using a humidity tray. Additionally, ensure the temperature around your rubber plant remains stable, as fluctuations can affect its overall health and growth. Avoid giving it extra water as this can lead to root rot.

    Potting and Soil

    Use a well-draining potting mix to prevent root rot. As the rubber plant houseplant grows, you may need to repot it into a larger pot to accommodate the expanding root system. A good rule is to ensure the new pot is several inches in diameter larger than the previous one to provide ample space for growth, similar to how rubber trees thrive in their natural environment.


    During the growing season (spring and summer), feed your rubber tree with a slow-release fertilizer to encourage healthy growth in light conditions. Reduce feeding during the fall and winter months. This approach ensures that the plant receives a steady supply of nutrients when it needs them most.


    Propagating a rubber tree plant is a rewarding and straightforward process. Whether you choose to propagate by cuttings or air layering, you can enjoy the satisfaction of growing new plants and expanding your indoor garden. As the rubber tree plant adapts to its new environment, you may notice the development of a new leaf. By following these steps and providing proper rubber tree plant care, your Ficus elastica will flourish.
