Hi alp and the rest of the manure loving gardeners,
Did you know one of the best ways to be kind and kill slugs is to fill a small bowl of Bear /Ale and place a few inches from the plants the slugs love it and enjoy a good night out and then drown
( What a way to go)
another tried and tested solution to slug/snail problems is a bit more time used making the solution is Garlic liquid, Just boil 1x full garlic and then when boiled for a few minutes until softer rather than harder crush all the Garlic and let it stand in the water for a while and then sieve through a strainer, use two table spoons per pint of this watered solution and pour a little of this around each plant "not to much and not to close to the plants stems, Keep a top on the bottle and store for further use, it keeps for ages,
The slugs/snails can't stand the smell,
The crushed garlic need'nt go to waste wipe it around the outsides of plant pots you intend to leave outside, again slugs etc wont climb up the pots trying to get inside and eat the young plants,
