The substrate of a cactus typically consists of well-draining materials that mimic its natural desert environment. Common components include a mix of potting soil, sand, perlite, and gravel, which help prevent water retention and promote aeration. This type of substrate allows cacti to thrive by providing the necessary drainage while still retaining some moisture for the plant's needs. Additionally, it often has a slightly acidic to neutral pH, suitable for cactus growth.
