Hi Victoria and
I am not an expert either but I grow over a hundred succulents. Ken is right about the water. In the winter I have my plants inside under very little light and they get water once a month.
If the plants are inside they do not get watered for six weeks or more. The only time my sucs get watered once a week is when they are outside and it is hot. Those fat leaves have a lot of water in them.
You do not need to dunk each plant above watering is fine.
