This is always a hard one isn’t it. It depends on what weeds,how fit & healthy you are, how many of you there are,how much time you have,how you feel about organic, personally I have sprayed in the past, but I don’t now & wont be doing again. I now realise that I value my soil so much more, but then I’ve stopped digging for that reason. I’ve just visited Charles Dowding’s no dig garden Homeacres& it was a true inspiration.
