How to repot a Christmas cactus for a thriving plant long after the festive season
The step-by-step guide to repotting a Christmas cactus as advised by experts
Alongside poinsettia and amaryllis, a Christmas cactus is a go-to plant to bring vibrant colour to your home during the festive season. But if you have had your Christmas cactus for a few years the roots will have grown and you will need to know how to repot a Christmas cactus to ensure it continues to thrive.
Regular repotting is an essential part of Christmas cactus care, which should be performed every 2 to 3 years or when the current plant pot is getting too small for the roots.
But getting the techniques and essentials right is crucial to ensuring your repotting will be a success. That’s why we turned to our plant and gardening experts for a helping hand in the matter. But rest assured, it couldn’t be easier once you know what to do.
How to repot a Christmas cactus
If you want to avoid having Christmas cactus problems, then regularly repotting your plant is key. Doing so every 2 to 3 years is optimal but you should also keep an eye on the rootball filling the pot. This is a clear sign that it’s time to repot to a larger container.
What you’ll need
- Well-draining soil suitable for succulents like this one at Amazon
- A plant pot with drainage holes, 8-16 centimetres wider than the previous one – we like this one at John Lewis
- Trimming scissors like these ones at Amazon
How to repot a Christmas cactus - step-by-step
Start the repotting process by choosing the right pot you’ll be transferring your plant into.
1. Choose the right planter
‘Choose a planter that has a drainage hole at the bottom to allow water to move easily throughout the soil, promoting good water circulation and avoiding root rot. This way, you'll prevent water from getting trapped in the pot, which can be fatal for the plant,’ recommends Petar Ivanov, gardening expert at Fantastic Gardeners.
‘Their new pot should also be larger than its previous container, about 8 to 16 centimetres bigger depending on its size and how long its roots are. Christmas cacti grow wide, so a wider pot will be a better choice than a deep one to provide your plant with stability.’

2. Remove the cactus from the current pot
Then remove the cactus from its current pot – and there is a method for that.
‘Turn it upside down in its current pot and gently tap it,’ says Steve Chilton, garden expert at LeisureBench. ‘This should loosen the roots and make it easy to lift the plant out of the pot. Hold the base of the stem when you do this.’
Petar Ivanov is one of the company's top-performing experts and manages over six teams of gardeners, delivering stunning landscape results and fostering a deep connection with nature through his work.
3. Trim the roots
Once it’s out, trim the roots if necessary. ‘Inspect the roots, trimming any damaged or unhealthy roots,’ advises Jack Sutcliffe, co-founder of shed manufacturer, Power Sheds.
4. Put new soil in the new pot
He continues, ‘Prepare a well-draining, slightly acidic potting mix, and place a layer at the new pot's bottom. Set the cactus in the centre of the pot at the same level as before. Fill the remaining space with fresh potting mix.’
5. Water
Then, once the soil is firmed, it’s time to water. ‘Water and let the plant sit for a couple of days in a shaded spot to recover and settle into its new pot,’ Steve advises.
Then you can water as often as you should water a Christmas cactus. And you’re done.
