A succulent garden doesn't need to be large. You should not water your succulents and other cacti too frequently. The roots may dry out quickly, which can eventually lead to root rot. I hope this has helped you gain a better appreciation for cacti. Given the right medium, watering needs for succulents in-ground should vary according to the season. Succulents can be placed around your home to increase oxygen. This helps to maintain a peaceful emotional state and reduce stress levels. It also helps stimulate rooting during propagation by stem cuttings and leaf cuttings.
