    Probably just there for belt and braces. The LD50 [**] on Glyphosate (if that is what your weedkiller is?) is , relatively speaking, very low. The Surfactant (i.e. soap) in the weedkiller which makes it stick to the plant is usually more toxic than the Glyphosate itself. So compared to, say, 2-4-D and whatever was in the old Weedol (something like Gramoxone I expect) you would be very unlucky to have a serious accident with Glyphosate. (Glyphosate IS toxic to Fish however)

    Having said that, getting into the habit of treating all such chemicals with respect means that when you do handle something more noxious (like 20% instead of 5% Vinegar for example ...) you will naturally be adopting "best practice" and more likely stay safe.

    [**] LD50 is the test to find how much of the substance is a Lethal Dose for 50% of the animals that are given it

    Getting back to the original question:- I'm sure that the answer you want is somewhere in ARMANDII's book. Either in the thread I posted above or still in his book. He's away fishing at the moment so he can't confirm this.

        Is it against EU to put my peelings in my compost bin? The food waste was no produced for the garden so I take it I'm breaking some law by doing this?

        I am totally fed up of the EU dictating to us *sigh*

          Well! Some of them. No, that's not quite correct!!! I think I'm mixing up the words 'some' and 'none' :scratch: - but I'm not sure :rolleyespink:

            coffee grounds do not work on the snails and slugs in Cambridge .... one of my clients got loads of coffee grounds for free from starbucks on a weekly basis, as she did not want to use slug pellets due to the bird feeders in her garden

            result .... all her hostas look like a sieve .... she said that next year she will use the pellets

            the coffee grounds also messes with the ph of the soil

            Perhaps it needs to be boiling hot and applied directly onto them?

                  How can they ban (or even prove that you've used) natural substances in your own personal garden? If I drop a pickle on my porch, will I be arrested? These laws are stark raving mad!
