I get questions about potting mixes and especially about pumice, so I have posted on pumice on the blog: http://www.thebulbmaven.typepad.com/. One hundred percent in agreement here, especially with the perlite dust business. Stores that supply material for bonsai sell pumice, but it’s white. Works just as well.
