Horseradish be-gone!

Hello there,
Any advice for removing horseradish from our plot? We took on a little allotment plot back in September last year and after some hard slog we’ve got great produce growing ...apart from where we inherited some rampant horseradish. I love horseradish but not grown directly in the ground as it’s a monster and we want the space for other things. We’ve dug deep around the shoots and roots, removed every last little bit we can find, cleaned the tools thoroughly afterwards only to find it creeping back up again. I did my 5th dig yesterday and have come to the conclusion that I would much prefer to be spending my time tending to other things. Any advice would be really appreciated :smile:

    I find a thick layer of cardboard covered in mulch of some sort for a few seasons gets rid of most everything, except the worst of offenders.  Never dealt with horseradish, so hopefully someone has some good advice.  

    Maybe cover it in a thick layer of cardboard mulched with well rotted manure, grass clippings, or whatever you have to hand now.. and leave it until next spring?

    Either that or spray it with glyphosate now that you've weakened it by digging most out.  Sometimes it's just about picking your battles.. and I feel a bit of spray occasionally here or there with difficult 'weeds' can bring the pleasure back into gardening for some individuals.

    We found that digging it out thoroughly was the best way ... but you do need to go down for a couple of spits depth  ... leaves from a few little bits of root that we’d missed popped up occasionally for the next couple of years or so  ... but they were easily recognised and dug out ... just don’t put any permanent planting such as fruit bushes in that area until you’ve got rid of it and been clear of ‘pop ups’  for 18 months.

    We had a nightmare with one plant, when we used to have our veggie patch at home.  We dug down about 1 metre.  We put Roundup or stump killer on the stump, covered it in a bucket (or plastic pot), and then covered back up with soil.

    We never otherwise have used weedkiller in the garden, but we couldn't continue to dig down any further.  It didn't come back.  Wouldn't grow it again.
