The Clivia cannot be described as hardy, even if it usually withstands short-term frost well. Without a period of dormancy, it is difficult to get this not-so-maintenant clivia to flower.

How should I overwinter my Clivia?
The ideal winter quarters for the clivia is bright and cool. The plant should not stand warmer than about 10 °C to 12 °C for at least two months, but it can also be four months. This dormant period is important, otherwise your clivia will not flower.
During this hibernation, slowly reduce watering to a minimum so that the plant does not wither. Fertilizer is not necessary until spring, could even harm your clivia. If you want to repot your clivia, it is best to do this after the winter break.
Which rooms are suitable as winter quarters?
The winter quarters for your Clivia should be frost-free and bright. A basement room, the garage or the stairwell are quite suitable, as long as it is not too dark there. Otherwise you can help with a fluorescent tube or an LED lamp. In the spring, slowly get your Clivia used to normal room temperatures again, and even then it should not be too warm. Now the location should not be changed if possible.
The essentials in brief:
- slowly water less and less
- do not fertilize
- Rest period at least 2 months
- hibernate at about 10 °C to 12 °C
- needs a lot of light even in winter
