Crassula may be available at a succulent nursery close to you. Mother Nature may provide water for plants during winter. However, you should water your plants well during the summer heat. Once established, the succulents can tolerate drought and only require minimal attention. Overwatering does not refer to how much water you give your succulents. Instead, it is about how frequently they are watered. The major difference between soil roots or water roots is that you place the succulents directly in the soil and only water them when they need it.
