If you have a rubber plant, you’ve probably noticed how fast they grow, and while they are generally a low maintenance plant, they can get a bit out of control if left unchecked. I’ve been growing and caring for rubber plants for many years, and today I’d like to share some of my best tips on how to prune them effectively. Not only will this keep them looking tidy, but it can also make your plant fuller and bushier.
Benefits of Pruning Your Rubber Plant
Pruning your rubber tree or plant has several benefits:
Propagation
The first major benefit of pruning a rubber plant is that you can easily use the cutting for propagation and get more plants for free! Rubber plant cuttings have a high success rate and are pretty hardy, especially when paired with good potting soil that supports healthy root development, making them a great choice for both beginners and seasoned gardeners.
Manage Size
Rubber plants, or rubber trees as they are sometimes called, can grow very large in the wild, reaching heights of up to 30 meters (about 100 feet). If left to grow unchecked, they can quickly become huge and difficult to manage. That’s why regular pruning is essential to keep them at a manageable size.
Additionally, the roots of rubber plants are quite aggressive and can cause damage to building foundations, fences, and irrigation systems. To avoid these issues, it’s best to plant them well away from such structures or keep them contained in pots.
Control Pests and Diseases
Rubber plants can be susceptible to pests and diseases, with scale insects being a common issue in my experience. These sap-sucking pests can quickly reproduce, leading to an infestation where the leaves yellow and fall off. While insecticidal sprays can be effective, I’ve found that trimming off the affected growth is a great way to help control an infestation and keep the plant healthy.
Promote Growth
Pruning a rubber plant encourages it to put energy towards producing fresh new leaves, which can help make the plant bushier. This is especially useful as rubber plants can become a bit leggy as they grow taller.
How to Make a Rubber Plant Bushy
So if you are wondering how to prune a rubber plant to make it more full and bushy, you can cut notches above or below the nodes of the plant which are the points where branches usually grow. This will make the plant go into survival mode and promote new buds to form and grow out near the notch.
When pruning, be careful not to cut too deeply, as this can harm the plant. Instead, cut a shallow triangle from the stem. For an even safer method, scratch just above the node. I usually use garden scissors, but a sharp knife works as well. Afterward, you should notice new buds forming within a few weeks.
When you cut the top of a stem, two new buds will form just below the cut, giving you two new branches. This helps you control the height of your plant and encourages a fuller, bushier shape.
Rubber plants have a thick, sticky sap that is poisonous and can cause rashes in some people, so it’s a good idea to wear gloves if you’re concerned. Always wash your hands when you’re finished. The sap will quickly stop running and form a protective barrier that helps the plant avoid rot.
FAQ
Can You Prune Rubber Plant?
Rubber plants are very easy to prune, especially when they’re younger. As they grow older, they can become quite large and the stems more solid and thick, so it’s a good idea to prune them regularly to keep them at a manageable size.
When to Prune Rubber Plants
I like to prune in the spring when any cuttings and notches you make will quickly grow back and heal. If you’re looking to shape or control the size of your plant, it’s good to prune early in the growing season so you can monitor and guide its growth throughout the spring and summer.
Conclusion
Pruning your rubber plant not only helps manage its size and shape but also encourages fuller growth and keeps the plant healthy. Whether you’re trimming to propagate, promote new growth, or simply keep the plant tidy, regular pruning is key to maintaining a vibrant and bushy rubber plant.
