Hi, I sowed comfrey seeds in Feb in the pollytunnel, new compost covered them and left them to get on with it. in March seeds were still sitting there doing nothing so | sowed some more - still nothing, sowed some more the other day is there something I should be doing I was under the impression they were a weed. Should I bring them into the airing cupboard, I have wanted Comfrey for ages and it is impossible to get as plants - can anyone help?
