If your home is in very hot, humid areas of the world, you might need to take extra good care of your succulents. You've likely heard that fertilizer nutrients can cause succulents to become brittle. This can be prevented by using a cactus potting soil that is both coarse and low in nutrients. It is important to have a good drainage soil. Every pot is not going to allow your plant to thrive when it comes time for watering. Pots with mineral components can allow excess water from your plant to drain out quickly after being watered.
