Slugs and copper
Slugs are eating all my veg. The only thing that seems to work are copper rings, but they are expensive for whole rows, so I limit them to spot plants like courgettes, squash and toms
Has anyone tried fixing copper sheeting all the way around the top of raised beds? - mine are 3m x 1m. It wouldn't be cheap, (around £40 per bed) but assuming it lasts several years then after 2 years it would be cheaper than all the nematodes, wool pellets, etc that I have tried. I was thinking of using a band 0.7mm thick and 50mm across.
Has anyone tried anything similar, and does copper work on a large scale?
