How to propagate a Fishbone Cactus

No matter how young, old, big or small your Fishbone Cactus is, you’ll be able to propagate it pretty easily.

How to propagate a Fishbone Cactus

Loved for their incredibly unique leaves, Fishbone Cacti are not only super easy to care for, but are also a perfect plant to propagate. No matter how young, old, big or small your Fishbone Cactus is, you’ll be able to propagate it pretty easily. 

In this post, we will go through each of the methods to help you choose which is right for you and your Fishbone Cactus. You’ll also find a list of tools you’ll need as well as how to diagnose and fix any issues you might come across along the way. 

Why propagate a Fishbone Cactus?

Before we get into the different methods, we thought it’s important to start with the various reasons why you might actually want and need to propagate your Fishbone Cactus. Firstly, who can say no to free plants? A great way to extend your urban jungle without having to spend any more is to propagate and grow the plants you already have. And if you don’t have any more space for plants, Fishbone Cactus cuttings make great gifts for friends and family. 

Another reason you might want to propagate your Fishbone Cactus is to reshape your plant. During the dark winter months, growth can become quite leggy and uneven. Pruning your plant can help encourage bushier growth and also help your Fishbone Cactus fit into the space better if it’s grown a bit long. Instead of throwing away those great cuttings, you’ve taken as you prune your plant, why not propagate them and create new plants! 

You might also propagate your Fishbone Cactus out of necessity if your plant sadly starts to develop brown, yellow, mushy or dry leaves. We would always recommend you look to diagnose the issue and attempt to fix it but if things don’t start to improve you might need to propagate a healthy part of the plant to keep it alive. When doing this you need to make sure that the part you are propagating is still completely healthy. Any issues with the cutting won’t go away and can very quickly kill your cutting.

What tools will I need to propagate my Fishbone Cactus?

Let’s start off with the easy part – knowing exactly what you’ll need when propagating your Fishbone Cactus. It’s important to make sure you have all the right things before you start propagating and take that first cut!

  • Healthy and mature Fishbone Cactus

  • Sharp scissors/shears

  • Spare pot(s)

  • Fresh soil and water

  • Newspaper or plastic sheet if you’re propagating indoors

What are the different methods I can use to propagate my Fishbone Cactus?

There are two main methods of propagation for Fishbone Cacti and luckily they are both quite simple. You can either propagate through leaf cuttings or through the division of the mother plant. Division tends to be best if you have quite a mature plant with lots of offshoots and stems so if your Fishbone Cactus is still quite small then leaf cuttings might be the best option for you. 

We will go over each different method in detail below so you can figure out which is the best for you and your plant!

How to propagate a Fishbone Cactus using leaf cuttings

This is the main method of propagating Fishbone Cactus plants as it’s suitable for all maturities and lengths of plant. Luckily, it’s also really easy and has quite a high success rate if the steps are followed.

Another great thing about the leaf cuttings method is that you can create several new Fishbone Cacti plants in one go! In the steps below we will assume you are just propagating one leaf but the process doesn’t change at all if you choose to do more.

  • 1

    Locate a healthy leaf

    When taking a leaf cutting you want to make sure that the part you are cutting is healthy to give you any chance of success. Avoid any sign of disease or pests as they will be transferred onto your new cuttings and very quickly take over your new plant. Leaf cuttings are much more susceptible to disease and sensitive to bacteria so this part is key to a successful Fishbone Cactus propagation.

  • 2

    Make the cut 

    Using sharp scissors or a knife make the cut across the leaf. Make sure your tools are clean as you don’t want to pass on any direct, bacteria or pests to the wound in your cutting.

    We recommend cutting diagonally across the leaf to increase the surface area for root growth. Cutting diagonally does also slightly increase the chances of bacteria getting into the cutting but the risks are low and the positives outweigh that risk in this case.

  • 3

    Let the cutting callous over 

    Leave your leaf cutting out in a warm but dry place for a few days. This will ensure the cutting wound callouses over and will help prevent any bacteria getting into the actual leaf when you place it in water.

  • 4

    Fill up your container with water 

    Next, you want to fill up a container with fresh temperate water to place your Fishbone Cactus leaf into. Make sure you don’t use hot or cold water as this can very quickly kill your cutting by burning or shocking it. We also like to use a clear glass to pop our cuttings into. It means you can keep an eye on how the roots are growing and spot any issues quickly. 

    When placing your leaf into the water, make sure that the bottom 5 centimetres are submerged but not too much more as this will increase the risk of leaf rot.

    Change out the water regularly 

    One of the most important steps in the Fishbone Cactus propagation process is to switch out the water in your glass regularly (every 2-3 days). This keeps the water free from bacteria and stops it from stagnating which is harmful to your cutting. Stagnant water will also start to smell so you’ll really want to avoid this.

    Be patient 

    This is the part of the process where things can get a little boring. It can take several weeks until you see any new root growth so just make sure you continue to regularly change out the water during this time.

    Plant your cuttings into fresh potting mix

    Once the roots on your Fishbone Cactus leaf cutting are between 5-10 centimetres long, it’s time to pot them into soil! We recommend using a high-quality potting mix to make sure your cuttings are getting enough nutrients. Carefully place your cuttings a few centimetres into the soil, making sure not to damage the newly formed roots as they can be quite delicate at this stage. 

    We recommend using a high-quality succulent potting mix as this will help with drainage and aeration in the soil. Overwatering and root rot is the number 1 killer of Fishbone Cacti so it’s important your potting mix contains ingredients such as perlite to help avoid this.

    Resume usual Fishbone Cactus care

    For the first few weeks of your cuttings living in potting mix, we recommend keeping the soil a little more moist than usual as the cuttings are used to living directly in water. Gradually reduce the amount you are watering and after two to three weeks go back to your usual Fishbone Cactus care. Soon enough, with enough love and the right environment, your cuttings will soon be long enough to propagate all over again.

How to propagate a Fishbone Cactus through division of the mother plant

This method of propagation only really works if your Fishbone Cactus is quite bushy and you don’t mind taking a chunk from it to form a new plant or two. This method is also perfect for those who don’t want to wait weeks and weeks for any new growth. With the process of division, you get more plants instantly!

  • 1

    Take your Fishbone Cactus out of its pot

    In order to propagate your mother Fishbone Cactus through division, you need to be able to locate the various vines and separate out the roots. Take your plant out of its pot carefully, trying not to damage the beautiful leaves.

  • 2

    Locate the various natural divisions

    Shake off the potting mix around the roots so you can see the entire root system clearly. Don’t worry too much if a few roots break, this is inevitable and shouldn’t cause too much harm to your plant. 

    When looking for a part of the plant to divide it will become very obvious that there are various different offshoots and stems on your Fishbone Cactus. The best way to locate them is by following each individual leaf and loosening the roots around it. There should be several sections of your plant that are completely separate from each other.

  • 3

    Separate your plant

    At this stage, you need to choose how many plants you want to end up with and how many sections will be in each plant. There’s no right or wrong way to do this and it depends entirely on how big and bushy your Fishbone Cactus is ☺️

  • 4

    Place each section in fresh potting mix

    Pop your mother plant back into its original pot (or downsize to a new pot if you’ve removed a lot from the plant). Then pot your new Fishbone Cactus into fresh potting mix. You want to make sure you are using a well-draining potting mix as this will help avoid problems such as overwatering.

    Continue normal Fishbone Cactus care

    You’re all done! Now all that’s left is to continue your usual Fishbone Cactus care routine and watch them grow.
