There are many things you can do to help a succulent that has become too watered, depending on the circumstances. You may notice leaves turning yellow and feeling crispy at the edges. To ensure your plant grows taller and spreads out, add additional succulent soil. The soil's top inch should be dry before watering. How I have successfully propagated these are by taking stem cuttings and laying the cuttings sideways on the soil.This way I start out with a fuller top and eventually have the plants trail. You can solve this problem by making sure your plant has plenty of light.
