good afternoon,i heard of a slug deterrent using copper and was
wondering if anyone had any experience of it in use,evidently copper
tube is beaten flat,cut into sections and formed into collars which go
around the plant at soil level,all thoughts welcomed.

I used copper tape on my aubergine plant last year and they had no slugs at
all. Of course, no idea if they would have if it hadn't been there. :-)

My neighbour's husband made her hostas a copper slug defence using the
inside of old stripped wire. She swears by it.
