Regular Succulents grow the most during the spring and summer. Once fall rolls around the plants like to take a break. During their fall/winter dormant period, watering should be reduced.
I located in Massachusetts, where is super cold in the winter. I have no choice to keep my plants inside the greenhouse. I only water them when I feel they are dry to prevent the roots from dying off. This can range between once every couple weeks and once every couple months.
However, there's one kind of succulents needing a different care - Greenovia.
