Hi Karen, I try to keep it cool and dry during winter..one time I had it indoors, this time it is sheltered under my growcamp outdoors so it gets protected from too much rain.
When temps are really hot it will immediately drop the leaves, but when it is cool and sunny in Spring it will make the new leaves happily. I provide shade for this one during summer, it is too hot and dry here. This is one Senecio I have not been able to make some blooms yet..still hoping though.
I adjust my watering, less in winter, just a little more during Spring and Summer, but I really have to allow it to dry.
