How to make a Christmas cactus bloom

The Christmas cactus can be made to bloom again if is subjected to:

The right light conditions – a week’s worth of short days and long nights. A typical northern hemisphere winter will give you approximately 8 hours of daylight and 16 hours of darkness. Put it on a windowsill in a room that’s rarely used, since even artificial lights will confuse it.

The right room temperature – Christmas cactus likes cool temperatures, no higher than 60ºF. 

Keira Kay, Bloom & Wild plant expert, explains how to make a Christmas cactus bloom: ‘For a second flowering, you will need to reduce the amount of light it’s subject to each day, ensuring it’s in the dark 12-14hrs, and stored in a cool room, with a temperature around 50-54ºF (10-12ºC). 

Rachel Martin, of Patch Plants, adds: ‘Christmas cactus likes quite a cool temperature and will produce more flowers if kept below about 68ºF (20°C), so keep her well clear of radiators.’

The right level of watering – ‘You would also need to cut back on watering, being careful to only water the top inch, and only watering again when it’s dry to the touch, this change in conditions will force the plant into a dormancy period – which is vital for new spring flowers.’

The right fertilization approach – knowing when to fertilize Christmas cactus is important: the quick answer is to do so in growing season, from spring to fall.

If you do all this you should make your Christmas cactus bloom again.
