the hedge would be yours then , the farmer could only cut upto the fence in that case. I think by law he would even be obliged to give you back any trimmings

? I don't know all or even most laws on spraying , but I know that there are new EU laws that state that for certain sprays the sprayer MUST have a licence to spray the chemical , he must be trained to spray it and he must use the correct sprayer and on suitable days. I know some farmers that have to wear complete chemical proof suits when spraying now, where only a few years ago they could just spray how they wanted!!! I thank god that my neighbour just spreads slurry onto the fields next to mine, mind you thats bad enough in summer with no wind to blow the smell away, my land is in a valley and the smell can hang around for days .... The only thing I can suggest is that you phone up defra and just ask what the laws on spraying are , or where to look for the appropriate regulations on their web site? There are most likely different rules for different sprays too , so unless you know what your neighbour is spraying , it may be very vague? I am sorry for your friend too, I hate to think what I have been sprayed with over the years

? I have been covered maybe a dozen times , doesn't bear thinking about !!!! My neighbour wanted to cut my hedge back with one of those b**tard flail things ....( there were other things he was going on about too) , well , I was in a foul mood that day so told him to ****ff and if he did cut it, I would kick the crap out of him !!!! The hedge has remained uncut (so far ) . He is one of those people that if you gave an inch he would take a mile , he even just stole two fields from another neighbour ,nearly 12 acres. The other chap is old and doesn't want to kick up a fuss , well the first one knows this and took advantage of it ... let him try it with me ......suffice to say I haven't always been as I am now !!!! These things are a real minefield though , and my reaction to it would be different to yours . You could maybe try scare tactics? ask him what he is spraying ? as you are severely allergic to many chemicals and could die if exposed to them !!! So if he could let you know what he is spraying and when,you could make a point of being out when he does spray. At least that way you would know what is being sprayed ? , and he may think twice about using it even ? As they say , many ways to skin a cat .....
