Hello Robin, Please see photo of my Hosta, one of the plants that are the most prone to slug and snail attack. They have no holes. They are in pots as I believe also yours are. All I do is put the pot on a support as you can see from the photo. But around the base on which the pot stands I wind two wires, about half way up the support, spaced about a centimetre apart. One is copper and the other is galvanized (zinc covered) wire. They must not touch each other. As Mr. Volta discovered many years ago when he invented the electric battery if you put zinc and coper in a solution, they will create a week electric current. When the slug or snail touches both wires with its wet slime, climbing towards your plants, they generate a week electric current that deters them. Once set up that is all you must do. On the photo you can see the brick support with the two wires at the bottom. The white tail is my cat not a Hosta. I hope that this helps. No poisons, no killings and all perfectly natural.ColinP.S. I'm trying to send it this way.Regards _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net> PBS Forum https://…
