I'm currently about to repot my little Chinese Elm. I've been doing some research about soil options and have determined that I'm going to go to my local Napa store and get a bag of Diatomaceous Earth granules to replace the MiracleGro I'm currently using. What I couldn't find a lot of information about was whether or not to use topsoil, moss, mulch, etc. in addition to the DE.
Does anyone have any advice or a reference for me to use? Any help would be greatly appreciated!
