Name: Lin Jarvis Peterborough, ON, CANADA (Zone 5a)
I live in Canada, and I buy rolls of Copper netting from a company called Lee Valley - instore or online at leevalley.com. I cut a strip of the netting long enough to go on the ground around the Hosta stems coming out of the ground. I seldom have a problem with slugs using the copper netting. I've been told the copper burns the bellies of the slugs and therefore deters them. Come spring, the netting is a bit ratty but I've had the same pieces out for several years. I simply resettle it around the stems each spring. If they move around too much because of wind before the plant is big enough to prevent this, I will often stick a piece of a stick into it into the ground anchoring it. I've learned to be sure to get totally outside the area the plant is popping up through or you will end up with leaves that have stretched the mesh getting through it and deforming the leaf which defeats the purpose of using it - we all want nice looking leaves. These pics were taken Aug 20 after almost a full summer season:
