I've been offered a supply of well rotted horse manure for my veg garden. Having read several books and googled the subject I'm getting more and more confused. Some sources say don't use it on potatoes, while others say its great for spuds, same with tomatoes, some people say its great for them others say dont use it on your tomatoes. As I said at the beginning it is very well rotted, I originally planned to spread a good layer over the plot and dig it in, so what do people think, is it good/safe for spuds and tomatoes ?
