There are many things that you can do to water a succulent that is too dry depending on its situation. You may notice leaves turning yellow and feeling crispy at the edges. You can also add more succulent soil to your container to keep your plant taller and further spread out. The top inch of the soil needs to feel dry to the touch before you water. I have found that this method works well for propagating these plants. I take stem cuttings and lay them sideways on the soil. I then start with a fuller top and end up with the plants trailing.
