Does any one know the best way to clear a well established horseradish bed?

Much as I like it on my Sunday roast I don’t’ really want it on my plot.
I have been trying for two years and it still keeps popping up. 

Its one of those plants where the slightest bit of root left in the ground will re-grow (imagine "couch grass on steroids")

Any ideas please?

Find some Czech neighbours, lend them some spades, and offer it to them for free!

I do like the way the use of the word 'arsenal' compels us to see horseradish as a weapon!

Digging up is the only way I'm afraid.
If you want to carry on growing a small amount, then pop some into a container to stop it spreading!

You may need to nuke it with herbicide when it's growing well.

remember the thread about the horseradish/rotovator disaster? The photos kept me awake at nights!

Unfortunately, as a Spurs fan, I do not have the "A"-word in my vocabulary.

I did try that originally but I think the plant actually ate what I sprayed on it. 

It's all died back at the mo but next year I will hit it when the young leaves come through see if that makes a difference.

Wait until it's actively growing in spring and zap it which a couple of applications of Glyphosate.

I have tried three times to grow Horseradish.........................and successfully killed it every time!!!!

Perhaps you'd like to go and give domw001 a hand

I pretty much got rid of a relatively small amount in my plot by digging out as much as I could, covering the area as much as possible to stop the plant getting new strength when leaves grew back, and glyphosating those leaves which did make it through the gaps in the brick layer!

I have also seen the picture of horseradish that had gone mad. It was the stuff of nightmares!

My suggestion would be to dig out what you can, sieve some of the soil into bags, cover the bed in a double thickness of decent quality weed fabric with the edges buried to exclude the light then plonk the bags of soil on top and use them to grow spuds or whatever you want in the spring. (you might need to add stuff to enrich them later on of course). By the time you have lifted the spuds you should be able to lift up the fabric and  see the stuff you missed trying to grow - you can now dig this out. Leave the fabric off and anything that comes up after that I would glyphosphate(or dig again!). You can tip the soil back into the bed at one end, refil the bags from the other cover again and repeat the process next year if need be.

two doses of "roundup" should do the trick....

Mixed at double strength. Be generous. 

I'm actually reasonably serious - there are times when you find that the roundup variations available to allotment holders are somewhat weaker than those available to professional growers (here speaks experience).
