How to Propagate a Rubber Plant

Rubber Plants (Ficus elastica) is one of the houseplant classics! With their elegant leaves and easy care routine, it’s no surprise why these plants are so loved. If you’ve been thinking about expanding your urban jungle, then propagating your Rubber Plant is a great way to go. They aren’t always the easiest plant to propagate though but we hope this guide will guide you through everything. From step by step methods, to what tools you’ll need and common problems, we’ve got all the answers to your Rubber Plant propagation questions! 

Why propagate a Rubber Plant?

Before we get into the details of Rubber Plant propagation, you might be wondering why it’s beneficial to propagate a Rubber Plant in the first place? Well here are some of the main reasons:

 

  • Create more Rubber Plants for free!

    This is often the most common reason for propagating your Rubber Plant as it’s a great way to expand your plant collection without needing to spend any more money! They also make great gifts for friends and family if you already have enough houseplants.

  • Save a dying Rubber Plant

    If you’ve accidentally overwatered (which is easy to do), over-fertilised or simply forgotten about your Rubber Plant for too long and it has started to die, sometimes the best way to save it is by taking the healthy stems and propagating them to create new healthy plants before it’s too late. 

  • Rubber Plants can grow pretty tall if given the right care and can sometimes outgrow the spot in your home.

    Giving them a trim is a great way to cut back some of the growth and propagating those Rubber plant stems stops them from going to waste which would be such a shame!  

What tools/equipment will I need to propagate my Rubber Plant?

Let’s start off with the easy part, here’s everything you’ll need to propagate a Rubber Plant. It’s important to make sure you have everything ready before taking any cuttings.

 

  • Healthy and mature Rubber Plant

  • Clean, sharp scissors/shears

  • Spare pot(s)

  • Fresh potting mix and water

  • Newspaper or plastic sheet (if propagating indoors)

  • Rooting hormone (optional)

  • Gardening gloves (optional)

  • Toothpick, peat moss, plant tie and plastic wrap (if propagating through air layering)

What methods can you use to propagate a Rubber Plant

There are two main methods of propagating Rubber Plants; stem cuttings and air layering. The first method is definitely the easiest and can be done using top cuttings or stem cuttings (more on that later). Stem cutting method is great for not only all maturities of Rubber Plant, but it’s also a lot easier so you don’t have to be a propagation pro to get this one right. 

The air layering method can be a bit of a challenge, and the success rate is lower. However, if you are pretty experienced at the other propagation methods and want a bit of a challenge, this method can be a lot of fun!

Propagating a Rubber Plant through the stem cutting method

 

  • 1

    Locate healthy stem(s)

    It’s really important when choosing which bit of your Rubber Plant to propagate, that the section of the plant is healthy. Avoid using any stems or leaves that show signs of disease or pests, most commonly brown or yellow patches on the leaves. You also need to make sure that the part of your Rubber Plant stem you’ve chosen to propagate has at least one node. 

    Nodes are stem joints where the leaves comeout from. You will pick the top of one of the stems for the first cutting, but you can then also take stem cuttings lower down to have a few shots at success. The process is exactly the same whether you choose the top cutting, or stem cuttings further down as well.

    Make the cut(s) 

    This can be the scary bit – especially with Rubber Plants that don’t have many stems so one cut feels like quite a big deal! Now that you have located the section of your Rubber Plant stem that you want to propagate, you need to cut it off! We recommend wearing gloves in this stage as the sap can be quite toxic if ingested.

    Use sharp scissors/ shears or a knife to make the cut. Make sure all of your tools are clean for two reasons. Firstly, Rubber Plants have toxic sap so you don’t want anyone to come into contact with the tools and react badly to it. Secondly, to avoid passing on dirt or any infection to the plant that might be lingering on your tools. Make the cut across your plant in a diagonal way as this increases the surface area of the cutting which helps in the propagation process.

    Take off any lower leaves 

    As you’ll be placing your cutting in water for several weeks you want to carefully remove any leaves on the lower part of the cutting that may end up sitting in the water. They will rot if they are sat in water for a long period of time so best to cut them off now. If your Rubber Plant cutting only has a few leaves then skip this step and make sure the water level isn’t super high (this will mean you will have to top up the water more often as there is an increased risk that the cutting will dry out).

    Fill up a tall container with water 

    Next, you want to fill up a glass with fresh water to place your Rubber Plant cutting into. 

    Use temperate water as extremes will harm your cutting and decrease your chances of a successful propagation. We like to use a transparent container, not only to see the roots grow which can be pretty cool but to keep an eye out for any signs of unhappiness. Spotting issues on your Rubber Plant cuttings early is the secret to solving them quickly!

  • 5

    Place your Rubber Plant cutting in water

    Make sure that the node(s) of your Rubber Plant stem cutting is sat in the water so that the roots will start to grow out from there. Place your glass in bright but indirect sunlight (direct sunlight can be too intense for new cuttings) and away from any temperature extremes.

  • 6

    Change out the water regularly 

    Make sure you are switching out the water in the glass every couple of days. This will stop it from stagnating and keep it free from bad bacteria that can really damage your Rubber Plant cutting. Stagnant water will also smell quite bad so it’s something you really want to avoid.

  • 7

    Now just wait 

    Once you’ve gotten into the routine of regularly switching out the water, Rubber Plant propagation can get a little boring. 

    You might not see anything for several weeks and sometimes even months but this is normal and not a sign that your Rubber Plant propagation won’t work. Rubber Plants grow slowly and the same is for the cuttings. 

    As long as your cutting is getting the right care and environment, you should see roots pop out soon, followed by new leaves!

    Plant your Rubber Plant cuttings into potting mix

    Once the roots on your Rubber Plant cutting have matured, you can now pot into fresh potting mix. Always use a fresh, high-quality mix to ensure your new Rubber Plant is getting the right balance of nutrients as well as reducing the risk of pests that comes from reusing potting mix. 

    Carefully place your cutting into the mix making sure not to damage the delicate newly formed roots and continue regular Rubber Plant care. Your Rubber Plant propagation is complete!

How to propagate a Rubber Plant through air layering

This method of Rubber Plant propagation can be a little trickier and fiddlier so we only recommend it if you are a slightly more experienced plant propagator (or you want a little bit of a challenge).

 

  • 1

    Locate a healthy stem

    When choosing the air layering method you want to make sure you are using a healthy and strong plant. With stem cuttings, you could get away with using the healthy part of the plant but as you won’t be removing anything from the plant for a while, it’s important that your entire Rubber Plant looks healthy. 

  • 2

    Make a vertical incision into the stem of your Rubber Plant

    Using a clean knife make a vertical cut into your Rubber Plant stem that is a couple of inches long. You want it to go about halfway through the stem. When making the cut it’s important you don’t slice all the way through to the other side of the stem. 

  • 3

    Open up the incision in the stem

    Insert a toothpick into the centre of the incision to hold it slightly open. This can be a little fiddly as you don’t want to poke all the way through the stem of your Rubber Plant so take your time when doing this.

  • 4

    Attach damp peat moss to the side of the incision

    You want to tie the peat moss around the stem with the cutting in making sure it stays damp but not soggy at all times. Use brown string, plant ties or garden wire to secure the peat moss to your Rubber Plant stem. 

  • 5

    Wrap up the incision using peat moss 

    Wrap a piece of plastic wrap around the peat moss and Rubber Plant stem. Wrap it firmly around the stem but still leaving some air pockets around the peat moss.

  • 6

    Once you see a new root you can cut off the stem

    After several weeks you should start to see new roots growing out of the peat moss. Once you see this you can slice the cutting off your Rubber Plant plant, remove the film and pot the cutting into fresh potting mix. Handle your new Rubber Plant cutting with care as the fresh roots will be delicate and easily damaged.
