Hemlock control

Not I'll, dead.

The roots are more poisonous than the leaves.

It likes the same wet spots and comes back. Individual plants are biennials.

Two tips:
- Make sure there is good water supply so cattle don't treat the roots up when going into ditches/streams/rivers to drink.

- Where practical, fence cattle off it (e.g. a strand of high tensile wire a metre or two away from the ditch where the hemlock grows).

EDIT: we refer to it locally as Water Dropwort
This is a different species to the hemlock that many of us have been talking about (with the purple spots, which has no preference for water).

It loves bare ground and recent road widening or similar is one way that is spreads rapidly, seeds get wafted along the bare earth verges by passing traffic and from there can easily seed into the bottom of the farm hedges and into the fields.

There's Hemlock water dropwart (Oenanthe crocata) which is the UK's most toxic plant, and grows in rivers and damp areas, and there's common hemlock (Conium maculatum) which grows everywhere basically.
 
If you dig up that plant in the photo you should see roots that look like dead mans fingers. Go careful touching it with bare skin mind- it causes terrible blistering.

This case history from the BMJ sounds terrible! Collected the roots and thought they were water parsnips!

Was it Socrates who chose hemlock as his choice for the death penalty. Dad used to tell the tale when we saw it growing in the brook. Cows used to graze the leaf , but it’s the white roots which are poisonous.

I've pretty much got rid of it around the yard with round up in late feb/early march.

Where did it all come from all of a sudden, never used to see it, now it's all over the place?

Yes. All of a sudden. Perhaps wetter & warmer weather has helped.
I have read that death by hemlock is a good death. Perhaps better than lying drooling in an old peoples home that smells of wee and your lights are on but no one is home🥲

Dead man's fingers is the roots of hemlock water dropwort, which is what this article describes. The photo I posted is poison hemlock, which is also mentioned, (C. maculatum).

Biennial, so spraying late fall so the first year rosettes don't survive the winter is best here. Then keep any that get missed from going to seed. 24D, remedy, crossbow etc. will kill better than roundup, and allow the grass to compete as well.
