Hi susan howard2 - there seem to be several postings at the moment about slugs and snails - the devastation they cause and their use as a food source for some birds, hedgehogs and other wildlife - mostly the former I think !!! They do seem to be thriving this year given the rain, rain and then more rain !!
We have a very varied wildlife environment in and around our garden but the natural predators seem to be unable to deal with the large slug/snail population of this year !!
It's very disheartening when established plants are eaten away and most of my annual seedlings have disappeared overnight this year - I almost lost 2 whole packets of delphinium seedlings before I could rescue them and move them indoors. My salad leaf crop is a midnight feast for the creatures !!
Anyway, enough of this rambling !!! Sorry to say that I do not have any perfect remedy for protecting seedlings/plants from attack - have tried several but none totally effective !!!! Sorry !!! Crushed eggshells, coffee grounds, pellets, vaseline around tops of plant pots, red leaved plants etc etc have not been effective. Have yet to try beer/cider traps, salt, bran etc.
But ... I have read a few articles recently about homemade garlic sprays for leaves which protect them from slugs/snails - I do intend trying this out as I've found that growing garlic around roses for the past 2 years seems to have prevented aphid attacks. In addition, the roses don't seem prone to viral infection. Although I do know that slugs/snails climb I'm also growing dahlias in hanging baskets so that at least I may see some flowers this year !!
Don'y know how helpful this posting is but like you I'll be interested in the experiences of other forumites.
Happy gardening !!!
