If you notice brown spots in your succulent, and it's usually kept in a sunny, bright area, you need to move it outside immediately. Over the next week, check your soil to see if it's dry. But, it has been so cold lately, and my poor succulents are freezing. If winters in your region are often cold and rainy instead of cold and snowy you might consider placing your succulents under a covered porch. If you are going to repot it, be sure to use a good-draining succulent soil. They need more sun than they are likely to get indoors.
