I love growing in my raised bed veggie gardens and sometimes the slugs love my veggies too. The smaller the starts, the easier they are to be destroyed. So last fall I found some copper tape on clearance and figured out that the roll contained just enough to encircle two plastic “flower boxes” and enough to surround the drainage holes on the bottom. This has been very successful! I have basil and a few lettuce plants that are growing in this prime real estate. When I want a few lettuce leaves to put on a sandwich, I do not want Swiss cheese lettuce.
