Alongside the whole length of our third garden (of the cottage we are soon moving to, not there yet) is a horse paddock. It is owned and maintained (quite nicely actually :d) by a house that is a bit up the road. Between the post and rail of their paddock and our garden is about a metre of ground which will belong to us. At the moment our boundaries are marked by a few trees, hawthorn, greengage trees, a walnut tree, weeds, nettles and unidentified plants. (see pic) We will put in fencing as soon as we can afford it but my problem is that as the horses are eating their paddock they are also stretching under their post and rail and eating whats in the gap and the tips of the trees that they can reach that are in our garden. (it also means that if any horse was to try and jump the post and rail at the end of their paddock,they would end up in our garden!) I am obviously concerned (as any horse lover would be) that they might be eating something that is poisonous to them as the owner of our soon to be cottage has not done anything at all to this part of the garden. So until it all comes into flower we cant be sure that this part of the garden is not full of ragwort So one of our first jobs we have to do when we move in, is walk that part of the boundary and remove any thing that would do them any harm. The present owner of our cottage did say to us in all seriousness, 'I did ask the horse owners if they wanted the grass clippings, after all the horses eat grass all the time, but they didnt want them, perhaps you should ask them again when you move in' .....eeerrr no Has anyone got a definitive list of what is harmful to horses? I know about Ragwort and Rhododendron, but what else? Heres a pic, this post and rail goes down the whole side of our third garden, its about 100feet long.
