    Default nematodes

    Slugs are really bad in this area, so the only way forward is to attack on all fronts at the same time. In my experience (which isn't vast) Nematodes are the best thing. They seem to make the biggest single difference,both straight away, and by vastly reducing the population of bigger slugs the following year. I also tried Victoriana's 'Vanish' this year, which certainly shrivelled them up for a few weeks, but it didn't seem to last. Maybe there's too much rain here in North Wales, so it got washed away, but it was supposed to last 'up to a year'. Comparatively, Nematodes are cheap, as they do the job.

    Good luck fellow assassins!

    What on earth is Victoriana's 'Vanish' - sounds very interesting. I've never heard of it - what do you do with it? And what does it do? And if it's good where do you get it from?

    Default nematodes

    We bought in a huge batch of nematodes last year which were very expensive and found quite a few large slugs (10cm +)amongst the potatoes and tomatoes at the end of the season -though very few smaller ones.Only a few eggs were found on the autumn dig. I hope this means next year will mean a reduced number of slugs. Time will tell. We grow on Peat so the moisture is very attractive to slugs. The rest of the crop seemed to be less munched by the beasts!. May try again next year to diminish their numbers further but we do have toads so we need to consider their needs too.

    Default Vanish

    Victoriana is a nursery advertised in GYO, and they sell some mineral salts called vanish, which is supposed to form an impenetrable barrier to slugs. As I said, it worked for a while for me, but not as effectively as nematodes. They say it's compatable with organic methods. You can also find Victoriana on the web.

    Default Nematodes and keeled slugs

    My understanding is that nematodes don't work on keeled slugs, or on snails. I've found that what works for me is to leave an old bit of wood on a patch and systematically kill every slug we find under it every time we go back to our plot.

    I also have a partially broken upturned flowerpot in a shady damp spot (by the waterbutts) that attracts snails. They congregate under it and I kill them. Sounds grim, but it's them or our lettuces.

    I have a similar problem with slugs and potatoes, in fact growing all crops because the place is infested, last autumn I put a couple of wheelbarrow loads of soiled straw from the chook house on 2 of the raised beds, left it a couple of months then when the weather wasn't too bad went and checked under the straw and the little darlings were all sitting there nice and snug in amongst the straw. I have just been out again to check and there are not nearly so many so I will be doing it again next autumn

    Default Slug traps

    We once tried beer traps but the buggers kept nipping out for a pee before they drowned ! Must be the northern bitter !

    Whilst slugs are a problem, I've found that Red potatoes suffer less damage than White ones. I purchase my seed potatoes from Thompson & Morgan and
    find that their notes on each variety i.e. resistance to slugs and disease very helpful.

    This year I intend to try Nematodes as well as I am fed up with slug damaged potatoes
