In summers, high temperatures make the growth of
Fairy castle cactus slowed down to survive in too hot a temperature.
As the cooler periods and rainfall begins, the
Fairy castle cactus starts growing. If the place you live in has hot summers and warm winters with more rainfalls, you aren't required to change anything.

Fairy castle cactus grow more in summer and rest in winter. It is because there is not enough sunlight for
Fairy castle cactus to grow in winter.
You can help your
Fairy castle cactus enter dormancy if you live in a place with cold temperatures by decreasing the temperature to 50℉ to 75℉ (15℃ to 25℃).
