I mean regular hogweed, not the giant variety thank goodness.

Over the last 20 years (there was none at all then) it has installed
itself in the fields and likes to come up in cleared areas around trees
and shrubs. I've not had much luck with glyphosate, the huge root seems
to laugh it off. I've tried cutting the flower heads off, on the theory
that since it's biennial (I think) it will go away, but the seeds seem to
set anyway.

Yesterday I dug a bunch of it up as best as possible, but of course there
was a lot of root left in ground. Is it likely to come back, or is this
a good method.

Lots of info on the giant variety but not so much on regular hogweed; it
has the same chemical that causes sunlight activated burns, just not so
much of it, and the flowering stems can get to about 6 ft.

Thanks for any tips,

Have you tried Pathclear yet? It should persist for longer than
straight Glyphosate and it inhibits germination of seeds.
