Once you notice the succulent looking plumped and replenished, usually within a few days to a week depending on the type of plant and the severity of dehydration, you can take it out of the water. Allow the stem to dry for several days before cutting it off. I can already tell that the mix will cause problems for succulents if they are too dry. With some propagation your garden can be filled with Stonecrop, and you'll have enough to gift to your loved ones. Drainage holes will be required at the bottom for potted plants.
