Courgettes don't trail, but most squashes and pumpkins do. I usually grow mine in a polytunnel and tie them in to strings then up onto the crop bars. The fruits then hang down and look good, apart from when I get hit on the head

You can grow them up any structure from decorative to purely functional and it certainly keeps the leaves, stems and fruit up out of harms way - and you way too. You do need to tie them in though, just about every day, and with heavy fruit you may need to support them with tights, or nets or something. Another good place to grow them is on a dung heap or compost heap. For slug pellets, you can now get Organic approved ones, which don't affect any other creatures, the corpses aren't left lying around for birds to eat and the pellets break down into innocuous naturally occurring compounds. The only drawback I have found with them is that the mice love them to line their nests, so if I sprinkle some round my lettuces in the evening, by morning they will all be gone. Later on when the dogs find the mouse nest it will be beautifully lined with blue

Usually I restrict my use of the organic pellets to underneath weed suppressing fabric, as they then are most effective, not being carried off by the mice nor breaking down in rain, but they are right there where the slugs tend to lurk. There are lots of other ways to trap slugs if you prefer not to try the organic pellets - lamping at night, picking up from around your plants, beer traps and so on.
