Hi Stephen, Sorry to see the slugs are beating you to the produce after all your work. So hope some of this is helpful.
I use epsom salts (much safer and gentler on soil than salt) to get rid of them. It penetrates slug skin and dehydrates them meaning they also can't breed more either. It is Magnesium sulfate so a natural mineral in soils.
I also scatter broken eggshells around the actual plants quite thickly, they don't like crawling over rough surfaces it and it benefits things like the cucurbits, squash and tomatoes from blossom end rot.
Stale beer in easy to climb into containers also attracts snails and slugs from the malt smell, they climb in and drown, it needs to be close to the plant needing help.
Bird baths work well as birds are natural predators so having them throughout the garden helps.
Human hair clipping work well if you can get enough
boots to donate :-) They simply won't go on it, added bonus is it adds nitrogen to the soil as it decomposes.
Diatomaceous Earth 4 tablespoons to a gallon of water, also works wonders but is a bit expensive so I tend to use the first 2 options. Amazing that there are so many cucumbers on such as small plant, always surprises me when you show the latest
gardening offers :-) Fantastic work.
