If you own a Christmas cactus, you'll know what a treasure they are during the bleaker winter months. But learning how to repot a Christmas cactus will ensure your plant remains healthy for years to come.
With the right Christmas cactus care regime, you'll enjoy a fresh round of blooms every winter. Knowing how often you should water a Christmas cactus is one thing, but you'll also need to pay attention to its pot.
‘By repotting a Christmas cactus, you can keep the same plant for years and it will continue to grow larger and more floriferous,’ says Kelly Dyer, indoor house plant expert at Patch Plants. ‘It’s one worth nurturing.’
To help you out, we've gathered top tips from garden and houseplant experts and created a guide on how to repot a Christmas cactus.
How to repot a Christmas cactus
First, you'll need to work out the best time to repot your Christmas cactus.
‘Repot your cactus immediately after it finishes blooming,’ says Andy Little, houseplant buyer at British Garden Centres.
Repotting every two to three years is ideal, but you should also keep an eye on the rootball. Once it's filled the pot, it’s time to repot the plant into a larger container.

How to repot a Christmas cactus – step-by-step
1. Choose the right planter
To start with, you'll need to select the right pot for your Christmas cactus. These plants grow wider than taller, so you'll need to pick the right shape, too.
‘When repotting, use a wide, shallow pot with good drainage and a mix of potting soil and sand,’ says David Denyer, expert florist at Eflorist.
Of course, you'll need to make sure the pot you choose is bigger than the original planter.
‘The new pot should be about 8 to 16 centimetres larger, depending on its size and how long its roots are,' explains Petar Ivanov, gardening expert at Fantastic Gardeners.
‘Choose a planter that has a drainage hole at the bottom to allow water to move easily throughout the soil. This promotes good water circulation and helps the plant avoid root rot.'
2. Remove the cactus from the current pot
Next, remove the cactus from its original pot.
‘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.’
3. Trim the roots
Once your Christmas cactus is out of its pot, you might need to trim the roots.
‘Trim any damaged or unhealthy roots,’ advises Jack Sutcliffe, co-founder of shed manufacturer Power Sheds. You'll need to use a clean, sharp pair of pruning scissors for this.
4. Plant up the new pot
Now, your plant should be ready to settle into its new pot.
‘Prepare a well-draining, slightly acidic potting mix, and place a layer at the new pot's bottom,' says Jack. 'Set the cactus in the centre of the pot at the same level as before, and then fill the remaining space with fresh potting mix.’
5. Water
Then, once the soil is firmed, it’s time to water the plant in.
‘Water and let the plant sit for a couple of days in a shaded spot to recover and settle into its new pot,’ Steve says.
And that's it! Keep up a steady watering regime (but don't overdo it, or you'll face Christmas cactus problems) and your Christmas cactus should bloom for winters to come.
