Weed from h#ll and how to best kill it
This weed has long horizontal roots and throw up spurs which form a climbing weed. If pulled, only the vertical spur breaks off.
Two of my raised beds have this growing in it and I have been unable to get ahead - the roots travel horizontally over several feet and go several feet down.
I'm about to douse the whole bed in Round-Up, but I don't think even that will be completely effective.
