We have a fair amount of comfrey on the allotment, which is starting to take over the universe: I know this makes an excellent plant feed, but I'm confused by conflicting advice: some folk say that I should cover the leaves with water (as for nettle feed), and others say that the leaves should under no circumstances be covered in water.
So: water or no water? Or doesn't it really matter?
