Moles are on the rampage across the allotments and they're becoming a PITA.
There's a very effective remedy called SORK, which are organic bulbs, grown
in Sweden, the smell of which, deters the pests.
They're hellish expensive at £13 for 10 bulbs. They do last for 2 years,
which suggests that they are sterilised before sale. It would also
discourage folk from raising there own seed.
Does anyone know what's the plants name? I'd like to get hold of some seed,
but googling hasn't helped.
