How To: Propagate a Rubber Tree

Have a Rubber Tree out of hand? Don’t be afraid to propagate! You now have the help of Leaf and Paw. Keep on readin’.

Sometimes doing something once is all you need to have the confidence to do it again. That’s not the case for plant propagation. After two (!) successful Monstera propagations from Monty, my monstera deliciosa, I had a much better understanding on how and why we propagate the way we do. But that doesn’t quite curve the fear of chopping heads and limbs off other plants.

Falling into Monty’s boat, Rudy, pictured above, my oldest houseplant of the family, was also becoming quite big. Actually, his size didn’t bother me, it was the bout of spider mites that infested him that did. For those who have never dealt with spider mites, they are purely creation of the devil and have no purpose but to spread anger and hatred on earth. Anyway.

After I cured Rudy of spider mites, he was left with some funny growth, weird leaves and botched stems. While I think everyone’s unique appearance make them special, Rudy had too many quirks and I wanted him to be pretty again.

When to Propagate

While I know I’m not the only one who prunes their plants for shallow reasons like these, it was time for a trim. I also want to add that rubber trees do grow quickly, and pruning to maintain a decent shape is necessary for some. Plus, ficus elastica have a tendency to get leggy if they are not exposed to decent sunlight. Either way, it was time for a haircut.

Like any houseplant, the best time to propagate and prune is in the early spring to late summer, when the weather is warm. This ensures a much better recovery for plants. I performed this in early September, so I was able to still have some sun for Rudy to soak up in NY.

Before we dive in, I want to talk about propagating healthy plants. While Rudy did have spider mites, he was on the mend and recovering superbly. I would not recommend propagating distressed or pest-ridden plants. Many times these pests continue on to affect the cutting which will then die shortly after propagating. I can’t stress enough that the best way to propagate a Rubber Tree, or any indoor plant in general, is with a healthy, established mother (or father) plant.

How to Propagate

Prep Your Station

Propagating and pruning is messy, especially for Rubber Trees or Ficus Elastica. If you have one you know what I mean. They ooze a milky substance when cut and leak everywhere. This sap is annoying to remove and is sticky and unpleasant, so be prepared.

You’ll need:
-A clean surface
-Paper towels
Rooting hormone (I always use Bonide because it actually works)
-A pair of sharp pruners
-A small pot with filled with a 50/50 mix of high quality gardening soil and perlite
-A gallon zip top bag

Before propagation, I like to gather all of my materials first. For you cooks out there, think mise en place. Now, let’s jump in.

  1. Pick the stem.

    Pick a healthy stem with healthy leaves. I picked a leggy stem on Rudy that didn’t receive much sun and would benefit from being pruned.

  2. Make the cut.

    Cut about halfway up this stem. Preferably, have a leaf right below the cut on the main plant. Immediately dab this cut stem on the mother plant with rooting hormone. Be careful of the oozing sap, it’s sticky and annoying. You’re now done with the mother plant. Time to focus on the cutting.

  3. Trim the cutting.

    Remove the bottom set of leaves from the cutting. I snip these off with my pruning shears. Next, if your cutting is too long (6″ is best) you’ll want to cut it in half like I did below. You’ll want to discard these leaves and this other half of the cutting – they’re useless. At the end of this step you’ll want 2-3 leaves on top.

  4. Pot the cutting.

    Dip the cutting in rooting hormone and grab your pot filled with moist soil. Unlike Monsteras, Rubber Trees do not need to root in water. These get planted right into fresh soil and are happy clams. He should look like this! How to propagate a rubber tree

  5. Provide a (mini) greenhouse.

    Remember that plastic bag? This is where you need it. You’re going to make a super casual greenhouse for your new baby. Place him gingerly in the bag and seal it 90% of the way. It’s important the leaves don’t touch the bag too much – you can use toothpick or chopsticks to keep its distance. Give Planty a good soak and place him in a warm spot with partial sun.

  6. Take care of Planty.

    Rubber Trees seem to take FOREVER to grow the initial new leaves. Keep the soil moist and his home warm – you need to be patient. In about 2-3 months your propagated Rubber Tree will grow roots. In about 6 months you’ll see new leaves. If you are propagating in the dead of winter, add a couple months to these timelines. Also, didn’t I mention not to propagate in winter? -_-

In about 6 months you can remove the bag and in a couple years you should see a new (and free) Ficus Elastica with leaves like this!

Now, I not only had a new Rubber Tree, but I had a happier Rudy. New leaves began sprouting immediately! Remember that the cut will never sprout leaves directly, so don’t be alarmed. Instead, new growth will spawn from the sides of the stem. Pruning stems on Rubber Trees every year can help keep their bushy appearance.

  1. Hello! For a year I can not stop trying to cut my ficus elastica but without success.
    I followed your method also the method in the water but I do not know the reason for my failure. Help!

    1. Hi Alaya, make sure the plant stays in a humid place while is it starting to root – some people let the new cutting dry out which leads to it dying. What are the issues you are having?
