Here are my supplies for reporting my succulents. Coarse builder sand, perlite and potting soil. You will also want some gravel or decorative rocks as a top coat. Not a requirement, but I do like how it looks. I bought pea gravel, white marble chips and black sand. I bought some large bags of gravel because I knew the extra could be used around my yard. I have to say the white marble chips were my favorite topper. Such a pretty contrast to the succulents.
