    I've put it in the compost and it hasn't spread, it just rotted down. My comfrey bed is next to a lawn and mowing controls it.

  • I wish we just had a bed of it, but it is creeping everywhere, this year appearing in new parts of the lawn where it hadn't previously been.  I don't know if it seeds like mad or spreads underground.  I know it has a chunky root system but we now have new shoots coming up in the grass at least 10 feet from the next nearest clump, which suggests seeds or a motorway under the grass!

    The lawn gets mown regularly, including the rough bit where the comfrey is most virulent but it doesn't seem to put it off, hence assuming some sort of glyphosate would be needed, and on this one I'm happy to use something stronger to control it as at the moment it's more of a nuisance than an asset.

    No longer newish but can't think of a new name so will remain forever newish.  B)

    Comfrey is very high in vitamin B12. The leaves were used to make poultices for various ailments. if you don't have any it is often found on riverbanks. one of the good guys but can be a real royal pain in the wrong place.

    If you use glyphosate that will kill the grass too. You need a lawn weedkiller.

     That might explain why we have so much of it in the garden - the house used to be a watermill and we have a burn running around three sides of the garden, albeit the other side of a wall, which is clearly not high enough to stop the natural spread of seeds...

    I'd be happy with a small patch for things medicinal, but I could set up a fracture clinic with the amount we've got!

    Are you sure it's comfrey? Mine doesn't behave in the way yours does. I've just had a tiny patch in the lawn next to the bed. It did fill the bed, which isn't that big about 1m x 2m, but hasn't gone any further.

    Busy some types of Comfrey have different habits or perhaps it doesn't like where it is perhaps to dry for it? image
