Did you know that slugs can't travel over copper? Some people line their gardens with copper tape to keep them out! I decided to plate the rim of a biodegradable (and plant nourishing!) peat moss pot with copper to keep the slugs at bay while the young plant develops. First I dipped the rim of the pot in melted beeswax to prevent the pot from absorbing any chemicals during the plating process, then I mixed a very fine copper powder with denatured alcohol, and painted it along the beeswax rim. The denatured alcohol evaporates, leaving only copper dust and beeswax. The copper powder fuses together and a new layer of copper grows over this initial layer as the pot is placed in the plating bath. The result is a rim of pure copper over a layer of biodegradable beeswax and peat moss.
