When it comes to Christmas cactus care, the key thing to remember is that less is more. As with most other cacti, Christmas cacti are a particularly good option if you have the tendency to kill off anything green in your home. 

One of our favourite houseplant ideas, the Christmas cactus is the perfect plant for both summer and winter and with a little know-how, it's relatively easy to care for and can last for years

Christmas Cactus care guide

Flowering plants are hard to come by at this time of year, especially when it comes to houseplants – and not everyone loves the needy poinsettia, though these poinsettia care tips can help. 

Thankfully, the Christmas cactus chooses this time of year to explode into a profusion of colour and life. They also add a touch of greenery to your indoor decor, mirroring any similar festive outdoor Christmas decorating ideas that you may have introduced to your garden or patio.

What you will need

Where to buy Christmas cactus

During the festive season, Christmas cacti will be readily available both online and in supermarkets – though they are less available at other times of the year. When looking to shop for houseplants online, it is important to choose a reputable stockist to ensure a good quality plant and reduce the risk of introducing pests into your home. 

Types of Christmas cactus

One of the best living room houseplant ideas for Christmas decorating – Christmas cacti are available in a wide range of colours from pink and red through to white and purple. 

There are two main types of Christmas cactus: S. truncata and S. x buckleyi. In the US, the Schlumbergera truncata species is known as the Thanksgiving cactus due to its slightly earlier flowering period, but in the UK, both types are sold as Christmas cactus. 

It is also worth noting that there is a similar cactus, Rhipsalidopsis, better known as the Easter cactus as it flowers between late March and May. The easiest way to tell the difference between these cacti is by looking at the leaves. 

‘Christmas cacti feature flat and segmented leaves with slightly rounded edges, while Easter cacti have leaves with rounded edges that are centred on the leaf,’ explains Elizabeth Marshall, Buyer at Hillier Garden Centres.

Where should I keep my Christmas cactus at home?

Cacti have a reputation for being unkillable houseplants and the Christmas cactus is just as straightforward. However, when it comes to Christmas cactus care, it is worth noting that there are some distinct differences between Christmas cacti and other cacti. 

‘Unlike other cacti and the Easter variety, Christmas cacti do best in bright but indirect sunlight. Direct sunlight can cause their leaves to bleach and burn,’ explains Elizabeth Marshall.  ‘To provide the ideal conditions, place your plant near a north-facing window where it can enjoy filtered sunlight.’ 

In terms of temperature, ‘aim for between 16-26°C and make sure it does not drop below 10°C in winter,’ advises Jessy Edgar, owner at Sprouts of Bristol.

How often do you water a Christmas cactus?

Not all cacti are created equal – in fact, there are over 2,000 different varieties – meaning you can’t take a one-size-fits-all approach, especially to watering. 

‘Despite being a cactus, the Christmas cactus will need watering far more
than you’d expect. Native to the tropical rainforests of Brazil, this plant is used to humid, warm temperatures – so mist it regularly,’ says Jo Lambell, founder of Beards & Daisies. ‘Water every two to three in the cooler months, and every one to two weeks when it's warmer.’ 

Watering is one of the key failing points when it comes to Christmas cactus care, so before watering, always test the soil by inserting a finger into the first two inches. If it feels dry, then it’s time to water. ‘Keep an eye out for any signs of overwatering such as black or red spots on the leaves or browning tips,’ adds Jo. 

Overwatering is one of the most common succulent care mistakes and is really easy to avoid if you test the soil. 

‘Use a high potassium feed every four waters in the flowering season, and an ordinary houseplant fertiliser every six waters otherwise,’ advises Jessy.

Repotting a Christmas cactus

Unlike other plants, Christmas cacti benefit from being repotted annually. 

‘Doing so will ensure that the plant isn’t overcrowded, has good enough drainage and that the soil has enough nutrients to support growth,’ says Evie Brownlee, plant expert at Grow Urban

When repotting the pot can be the same size or, if the plant is showing signs of being rootbound, a few inches larger than the current pot. ‘Christmas cacti like to be repotted right after blooming,’ advises Julian Palphramand, head of plants at British Garden Centres

  • Shrivelling or scorching This usually happens when you've placed your plant in direct light. A Christmas cactus prefers a bright, shaded spot. Shrivelling can also happen if you have over (or underwatered) your plant. To ensure you don't overwater, check that drainage holes are open and try changing the soil to a grittier mix to help the water drain through easily.
  • Dropping buds Turning your heating on and off often can sometimes affect the flower buds on a Christmas cactus. Repeated fluctuations in temperature can result in them dropping off before they reach their full potential. Keep the plant in a warm spot to avoid this occurring.
  • Not blooming ‘This may be due to temperature or light inconsistencies. The Christmas cactus is a short-day bloomer, which means it sets blooms when exposed to longer nighttime hours and cooler temperatures. So, in the months leading to Christmas, ensure they get 12-14 hours of darkness and temperatures of about 10-12°c,’ explains Beth Chapman, founder of Leaf Envy
  • Leaves turning pink or red suggests that the plant is receiving too much sun, move it to a shadier spot.
  • Grey mould on leaves  ‘This is Botrytis blight and means that the plant needs to be disposed of,’ says Julian.  
  • Lack of growth Christmas cacti are fast growers. If your plant is stalling and isn't producing any new leaves or buds, it could be that it's in the wrong pot. These plants don't like large pots and planters, they prefer a more snug fit.


How do you propagate a Christmas cactus?

The best way to propagate a Christmas cactus is by taking a leaf cutting. This can then be planted in cactus compost or suspended over water until roots form. They can then be potted up into a nursery pot to continue growing. 'It typically takes about 12 weeks for the plant to root, so propagating in the early spring will give them plenty of time to grow before you give them as gifts next Christmas,' says Elizabeth Marshall.

How do you get your Christmas cactus to flower?

The reward for diligent Christmas cactus care is the abundance of blooms that will appear come winter. As one of the winter flowers that bloom at Christmas, Christmas cactus are a great way to bring life into your home.

‘To ensure a stunning display, keep your plant drier from late summer to early autumn, and make sure it gets between 12 and 14 hours of darkness a day,’ advises Jessy Edgar, owner at Sprouts of Bristol. ‘When in bloom, try and keep the plant moist but not soggy as this will help the blooms last for longer.’

Deadhead faded blooms by pinching off at the point where the flower joins the leaf – this will make the plant look cared for and promote more flowers.

As with caring for a peace lily, the Christmas cactus will also benefit from dusting from time to time.

Follow this guide to caring for your Christmas Cactus and your plant should be happy and give you beautiful blooms year after year.
