I have this weed in my chile patch. It's shown up every year for quite a while and every year it's a little more invasive than the year before. I can cut it off pretty deep, several inches, and not hit its roots. I suspect there's a very deep runner or something and it sends up plants from there. Round-up (desperate here) seems to kill the particular plant but not the entire system and its mothership. It roughly radiates outward from a point slightly outside my property, on the other side of our fence.

I've never seen this before its first appearance in my garden. It's a toughie.

if you are going to use roundup/glyphosate on it you
want to use it when there are plenty of leaves and it
is actively growing.

if you don't want it to grow put a few layers of
cardboard over it and put down a nice layer of wood-
chips. not much can survive being smothered. if it
doesn't get it all the first time rake back the
woodchips and put down a few more layers of cardboard
and replace the woodchips.

can you approach the neighbor to see if you can
remove it from the other side of the fence too?
