If your succulent is showing brown spots, and you normally keep it in a sunny spot, then move it immediately to the shade. 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 it is cold and rainy winters in your area, you might be able to place your succulents underneath a covered porch or overhang from your roof. You should repot it in a soil that is well-drained. They are used to getting more sun than they will see indoors so make sure to place them in the best light area of your home.
