How to propagate a Croton Plant

These genetically unstable plants are super unique in the houseplant world as no two will ever really look the same. This is why we are all obsessed with propagating Croton Plants, we are never really sure how they will turn out! Propagating Croton Plants can actually be very simple if you have the right method and tools. It’s worth noting here that the sap found in Croton Plants is toxic and will cause skin and stomach irritation if you come into contact with it. This is why you should always wear gardening gloves, clean your tools after use and keep any children and pets away from your plant whilst propagating. 

In this post, we will guide you through the entire process of Croton Plant propagation so that you’re fully equipped with the knowledge you need to create new plants. Below we will cover the tools you’ll need, what method is the best one to use as well as a guide to diagnosing and solving any issues you come across.

Why might you want or need to propagate your Croton Plant?

Before we get into the step by step propagation guide, we thought it would be useful to go over the various reasons plant parents choose to or are forced to, propagate their Croton Plants. The main reason is the ability to just wanting to multiply the number of Croton Plant plants you have without having to shell out any more money on houseplants! Croton Plant cuttings make great gifts for friends and family as they are loved for their unique and colourful foliage. 

Another reason why plant parents choose to propagate their Croton Plants is that often these plants don’t always grow how we would want them to. They can very quickly become too long or very leggy. Pruning your Croton Plant encourages bushier growth and is a great way to cut back that straggly and small winter growth. But instead of letting them go to waste and throwing away those incredible Croton Plant cuttings, propagate them and start a whole new mother plant! 

It can also happen that you notice your Croton Plant plant is starting to look a little ill and is dying. This is when you might be forced to propagate your plant to keep at least some of it alive. If you’ve tried to fix the issue but nothing seems to work then the best thing to do is cut off the healthy stems and propagate them to create new Croton Plants.

What tools/ equipment do I need to successfully propagate my Croton Plant?

 

  • A healthy and mature Croton Plant 

  • Sharp scissors/shears

  • Cleaning cloth

  • Gardening gloves (Croton Plants are toxic)

  • Spare pot(s) with drainage holes

  • Fresh soil and water

  • Newspaper or plastic sheet if propagating indoors

  • Toothpick and peat moss (if using the air layering method) 

What are the different methods I can use to propagate my Croton Plant plant?

Stem cuttings are the most common method of propagation for Croton Plants. This works best for slightly more mature plants as you’ll be taking a fairly long stem cutting to make sure it’s a success. 

The second method of propagation is through air layering. It’s a slightly more complex method of propagation that isn’t always a success. We recommend this for more experienced plant parents, or those who are looking for a challenge. Below you’ll find a detailed step by step process of each propagation method so you can figure out what’s best for you and your plant.

How to propagate a Croton Plant through the stem cutting method

 

  • 1

    Locate a healthy stem on your Croton Plant

    Only ever take stem cuttings from healthy parts of your Croton Plant. If you try to propagate a part of the plant that’s looking a little wilted, yellow or dry, the problem will just get worse once you’ve taken the cutting as they are much more susceptible to disease. You want to choose a stem cutting with at least 5 leaves on it.

    How many stem cuttings you take it totally up to you. It doesn’t impact the process at all but just depends on the maturity of your plant and personal preference.

    Make the cut(s) 

    This is the scary part and the reason why a lot of plant parents shy away from propagating their Croton Plants! Now that you’ve located the section of the stem that you want to propagate, you need to cut it off! Use your scissors or shears to cut off the stem. Make sure you clean your tools after making the cut as the sap in Croton Plants can cause skin and stomach irritation.

  • 3

    Remove any lower leaves 

    As you’ll be growing your Croton Plant cuttings 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. This is because they will start to rot and release bacteria into the water which can harm your cutting.

  • 4

    Let the cutting callous over

    Now that you’ve taken off the lower leaves, you want to leave your Croton Plant cutting out in a warm but dry place for a day or two. This will allow the cutting to callous over which helps to prevent your cutting from rotting.

  • 5

    Fill up a container with water 

    Next, you want to fill up a container with fresh water to place your Croton Plant cutting(s) into. Make sure the water is temperate to avoid shocking or burning your cutting. We prefer to use a transparent container when growing the cuttings. Not only can you see the roots starting to grow, but it’ll also allow you to spot any issues early, giving you the best chance at solving them.

    Change out the water frequently 

    Make sure you are refreshing the water every other day. This will help keep it free from bacteria and stop it from stagnating. Stagnant water also smells pretty awful so you really want to avoid this. 

  • 7

    Now all that’s left to do is be patient 

    As long as you are frequently refreshing the water, you just need to wait and be patient. As long as your Croton Plant cutting looks healthy, you’ll see roots in no time at all!

  • 8

    Plant your Croton Plant cuttings into potting mix

    Once the roots on your Croton Plant have grown to about 5 centimetres, it’s time for you to pot in into soil. Use a high-quality potting mix to make sure your plant is getting the right balance of nutrients.

    Resume your usual Croton Plant care routine

    The propagation is complete – you can now continue to care for your new Croton Plant plant as you would the mother plant.

How to propagate a Croton Plant plant through the air layering method

This method of Croton Plant propagation can be a little trickier and fiddlier so we only recommend it if you are a slightly more experienced plant propagator! The success rate is also lower than the stem cutting method which is important to keep in mind. 

 

  • 1

    Locate a strong healthy stem

    When propagating your Croton Plant through the air layering method you want to make sure you’re using a healthy and strong part of the stem. Avoid using any part of the plant that is discoloured or showing signs of pests/sunburn etc. This will impact how successful your propagation is so choosing the right part of the stem is key to this method of Croton Plant propagation. 

  • 2

    Make a vertical incision into the stem of your Croton Plant

    Whilst wearing gardening gloves, use a knife make a vertical cut into the stem that is a couple of centimetres long. You want it to go about halfway through the stem rather than slicing all the way through. Make sure you clean the knife after making the slice as the sap is toxic to humans and pets. 

  • 3

    Open up the incision

    Isert a toothpick into the centre of the incision to hold it open. This can be a little fiddly as you don’t want to poke through the stem of your Croton Plant so do this slowly and carefully.

  • 4

    Attach damp peat moss to the stem

    Tie a handful of peat moss around the stem covering up the incision. Use brown string, plant ties or garden wire to secure the peat moss to your Croton Plant stem.

  • 5

    Wrap up the peat moss 

    Use a piece of plastic wrap around the peat moss and stem of your Croton Plant. Wrap it firmly around the stem whilst still leaving some air pockets around the peat moss. This will allow you to occasionally mist the peat moss to keep it a little moist at times. 

  • 6

    Occasionally mist your stem 

    Every now and again use a spray bottle to moisten the peat moss. This will give some moisture to the stem and encourage roots to grow from the incision.

  • 7

    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 stem off your Croton Plant plant, remove the film and pot the cutting into fresh potting mix. Handle your new Croton Plant cutting with care as the fresh roots will be delicate and easily damaged.
