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's been so cold lately and my poor babies are freezing. If your winters tend to be cold, rainy and snowy than cold, then you might want to cover your succulents with a porch or roof overhang. If you are going to repot it, be sure to use a good-draining succulent soil. To keep them healthy, they need to be exposed to more sunlight than they will get indoors.
