According to this extension article, it's not the color you should be concerned about but the wood. The coloring is non-toxic, but the wood used for colored mulch is scrap wood and could contain creosote.


You may want to skip the mulch altogether for your potting soil. You could use orchid mix if you have any on hand. It is basically bark.
