Yeah, we tried with our own slips the next year, but that didn't go
anywhere. I can't remember if we messed them up or if they didn't work.

and, as I said, full of slug holes. Eventually we just decided they were
only an interesting gardening experiment and gave up with them.
Lots of space, water and feed needed too.

*nod* Nick thought we should try again and make sure we water them more
this time. I don't think we got much slug damage at all, but he did
nematodify the whole place, so that will have helped.
