How to get Christmas cactus to bloom
One of our favourite houseplant ideas, the Christmas cactus makes for the perfect festive gift or Christmas table centrepiece idea. However, in order to ensure blooms, pre-flowering care is essential.
'During October and November, Christmas cactus plants should be kept relatively dry and cool until flower buds begin to appear,' says Evie Brownlee, plant expert at Grow Urban. 'The Christmas cactus should be fed during the spring and summer with a cacti and succulent feed.'
Light levels are also key to getting your Christmas cactus to bloom. 'Christmas Cactus need darkness to encourage them to flower so once the nights are darker and it gets at least 13 hours of darkness a day, then it will start to bud and bloom,' says Morag Hill, owner of The Little Botanical.
Once your Christmas cactus is forming buds, 'feeding your it with a high potassium feed can encourage longer-lasting blooms,' says experts from the RHS.

What to do after Christmas cactus has bloomed?
Once your Christmas cactus has bloomed, it is important that you continue your Christmas cactus care – otherwise, you might not get flowers next year.
'Post flowering, they also require a resting period from when the blooms die back to March,' says Evie Brownlee, plant expert at Grow Urban. 'Once flowering is complete this genus requires repotting annually. Repot with a cactus and succulent compost to ensure the plant the correct amount of drainage.'

What to do if your Christmas cactus doesn't flower?
If your Christmas cactus doesn't flower, start by repotting it with a free draining compost. 'Use a mix of 60% peat-free substrate at 20% perlite or grit and 20% fine-graded orchid bark,' recommends experts at the RHS.
This will increase the amount of nutrients in the soil which can encourage blooming. 'I like to let medium get slightly dry between watering. During the warmer growing months, this should be done once or twice a week, though this can be reduced in the winter.'
It is also important to make sure that your Christmas cactus is not suffering from any draughts (hot or cold) and that it is getting at least 13 hours of darkness per day.

FAQs
Do Christmas cactus flowers fall off?
Yes, Christmas cactus flowers fall off when they have finished blooming. It is important to remove these to prevent the spread of disease. However, if fresh blooms or buds are dropping, this is a sign that something is wrong. The problem could be a change in climate or location (drafts of hot or cold air can cause the buds to drop); or too much or too little water.
'Once buds have formed on the plant it must not be moved, this will cause the buds to drop off,' adds Natalie Bourn, shop manager of Between Two Thorns.
What is the best temperature for Christmas cactus to bloom?
'Once buds appear on a Christmas cactus and during the flowering period a temperature of 18 ̊C to 21 ̊C is best,' says Natalie Bourn, shop manager of Between Two Thorns. 'During the rest period – the time period immediately after flowering – the plant should be kept between 10 ̊C and 15 ̊C.'
