Q.Care For Succulents In Winter
At what temp should I bring them indoors. I live in zone 9

It depends on what succulents you have. Some are hardy to zone 3, such as Sempervivums (hens and chicks) and sedum. They can stay out all winter. Since you are in zone 9, many of yours probably can stay out all winter. If you know the type you have, you can look them up and find their hardiness rating.
