Copper foil versus slugs
I just put raised vegetables in my backyard (way north California, on the coast) and am enjoying my first organic vegetable garden. But the slugs are eating my chard! They haven't found the lettuce yet, but I'm sure it's only time. I've researched the various barrier/bait options and have a question about maintaining a copper barrier. At $.79 per linear foot, this would be an expensive option, but I'd be willing to do it if I would get a low-maintenance solution that would last for years. My question is whether it is still effective once the copper tarnishes and once installed, how long it would last. I'd appreciate your feedback. Thanks.
