Age old problem, I've tried to grow lettuce in the ground but they get hammered by slugs. The lettuce grow well but when I pick they are riddled with masses of little black slugs, which isn't appetising. I won't use pellets and don't have access to barriers of coffee grinds or eggshells. I have raised beds with wood sides so I think this is a perfect environment for them, the slugs not the lettuce that is. Last year I tried some lettuce in a 1/2 barrel, still got lots of slugs. This year I'm thinking of trying hanging basket lettuce but I know that will give me watering issues let alone finding places to hang them. I do grow cut and come again in trays in the greenhouse successfully but would like to grow a beautiful row of whole lettuce if possible. Anyone have successful methods or maybe resistant varieties? they'd like to share.

Nematodes. Brilliant, and don’t harm anything else. But not cheap. -
I pick the slugs off in the evenings and that does seem to reduce numbers of the tiny (baby?) ones too eventually. But of a faff but the most effective way I’ve found in the long runAll at once I hear your voice
And time just slips away

Thanks SP, not sure if there are other producers but the major one I can find looks to sell a 40 sqm pack for £14 and it says 6 weeks cover, so that would be very expensive to keep applying over a 6 month or so growing period, in your experience is that how it works?. I also only need about 7 sqm for 1 bed of lettuce so will maybe see if I can find smaller packs elsewhere.Comment

Just been reading the homemade nematode thread on here. Not a good read just after breakfast

Have used them, fairly sure you could split the pack for several applications. Just mix up what you need as you need it.Originally posted by mcdood View PostComment

Thanks Logunner. From what I've read they say they won't live long enough to keep reapplying, have you tried in practice?.Comment

I "think" I've read that red lettuce are less attractive to slugs than green.
You could try a packet of mixed lettuces and see which fares better.Comment

Not tried, but i remember the pack had to be stored in the fridge. Not sure on how long they advised before using, but I’m sure there will be a wide margin built in... not that a commercial enterprise will ever admit to that.Originally posted by mcdood View Post
Did read some time ago about the homemade stuff, wonder if the commercial ones can survive in a waterbutt for several months?Comment

slug traps do reduce the numbers quite well, I find..

Glad to see that chap's not wasting beer.Originally posted by Thelma Sanders View Post
I like the idea of using a lidded trap. It might prevent pets and wildlife from consuming the contents.
I remember a few years ago rescuing a baby hedgehog that was staggering around someone's garden. It looked pretty ill, so I took it to a local animal charity to see if it could be saved. It was pretty sorry for itself but made a full recovery.
it turns out that the owner of the garden had put out beer traps for the slugs. Slugs are something of a delicacy in the hedgehog world and young Spiky had been feasting on beer-marinaded slugs that night and was as drunk as a skunk.Comment

I have some bullet shaped beer traps that work well, easy to insert in the ground. They have a roof on stalks that can be tilted sideways to remove the inner sleeve which has a hole in to let the beer out but keep the slugs in and can be easily emptied. This needs to be done fairly often as the drowned slugs stink.Comment

I can absolutely recommend Nemaslug - I've used it for years. When I first moved in here, I couldn't even leave dog food out in a bowl - it would get invaded by thousands of slugs over night.
Nemaslug brought it right down to more manageable levels, and in conjuntion with evening slug pickings and hungry chickens, I can grow most things in my garden now.
You can get it online for 12, 13 quid maybe in their smallest packs. I tend to only apply once a year, and buy enough to do both my back garden and my plot. Now I have two plots, but not getting any slug damage on my no dig beds, so maybe that could be part of your answer too - to go no-dig?Comment

The traps are called slug inn and are 6 fo a tennerComment

Thanks all. Sariss I am no-dig so it isn't that though I think my raised beds with wood sides do provide a good hiding place for the slugs. I know Charles Dowding has beds without sides and I always get salad leaves envy watching his vids so maybe I need to experiment and remove the sides on a couple of beds and see if that helps. I will also give nematodes a shot this year.Comment
