Propagating Rubber Plants: The Art of Creating Green Gems

The rubber plant (Ficus elastica) is not only visually appealing but also incredibly low-maintenance. So, why settle for just one plant when you can easily multiply your rubber tree and share the green gems with others? In this article, we’ll explore the art of propagating rubber plants through two methods: cuttings and air layering. Whether you’re a seasoned gardener or a beginner, these techniques will help you create magnificent and vigorous saplings from your existing plant.

Propagating Rubber Plants from Cuttings

When it comes to propagation through cuttings, you have two options: main stem cuttings or node cuttings. Both methods are relatively simple and require a clean, sharp knife.

Propagating a Rubber Tree from Main Stem Cuttings

To start with main stem cuttings, locate a healthy shoot and trim a five to ten centimeter-long shoot tip. Make the cut just below a leaf base, ensuring it is angled. Remove all the leaves from the shoot, except for the top one. Take note that cutting the rubber plant will cause a white-milky sap to seep out, so it’s advisable to dab it with a damp cloth.

Prepare a pot with drainage holes and use special growing soil as a planting container for the cutting. An ideal substrate would be a peat-free sowing soil like the Plantura Organic Herb & Seedling Compost. Place the cutting in the pot and moisten it with a spray bottle. The sapling will thrive in warm, bright, and humid conditions, so consider creating a mini greenhouse by covering the pot with a plastic bag. Remember to periodically remove the bag for better airflow. The sapling needs a minimum temperature of 25°C to grow. After about three months, you can transfer the sapling into a larger pot.

Propagating Rubber Plants from Node Cuttings

If your rubber tree has already grown to a substantial size, you can propagate it through node cuttings. Select a woody shoot with leaves and small bumps called nodes. Cut a three to four centimeter-long piece with a node from the shoot and remove the leaves. Place the cutting in a pot with growing soil, just like before.

Rubber Plant Propagation by Air Layering

Air layering is a fascinating technique that allows you to transform one plant into two. This method, known as the “wedge method,” encourages a specific part of the plant to form roots, even if it’s not in the ground.

To air layer a rubber tree, choose a healthy and robust shoot. Cut diagonally along the shoot, not exceeding halfway. Remove any sap with a damp cloth and apply rooting powder to expedite root formation. Insert a wooden wedge or match into the cut to prevent it from resealing.

Next, wrap the cut area with a layer of moss, which gives this method its name. Cover the moss with cling film and tie it below the cut on the shoot. Ensure the moss remains adequately moist, and in a few weeks, roots should start to form. Please note that this process requires patience, as it can take six to ten weeks for a sufficient number of roots to develop. Once the shoot has ample roots, cut it off from the main shoot and plant it in a separate pot. The remaining part of the shoot will regrow leaves over time.

With the art of propagating rubber plants mastered, it’s essential to provide your brood of little trees with proper care. Explore our comprehensive guide on caring for rubber plants to ensure their healthy growth.
