Succulents are always better off under watered than over watered. Once a week or every two weeks depending on temperature and humidity should suffice. Let soil completely dry in between watering.
Any leaves that fall off during Transit or shortly after potting (which is completely normal) can be set out on dry soil mix in indirect sunlight and propagated!
