There is another web site that has been running an

slows them down )

I remember watching a slug slither its way happily over the
copper tape I had put on a large plantpot. :-(

The results of this study will be interesting

Pity they aren't including wood ash in the trial. When we had a
woodstove I used to put a circle of the fine ash round individual
brassicas and in rows between the strawberries, which seemed to work
well.

Woodash is quite caustic so I am not surprised the slugs didn't like it.
Potash was the old name for it. Nice source of potassium.
