Is this young Horseradish growing on waste land?

I remember reading the thongs ( roots) can go down 10ft plus so if you plant it some where make sure your not going to move it again.

It'll take several years to get to that depth. My strategy is to lift it every year, and start again from thongs somewhere else. That way it can't develop into a jungle.

defiantly grow in a container. i cut back and remove most roots each year and it always comes back.

I have loads of the stuff growing on the wild part of my allotment.    I wait for the leaves to grow, then chop them off and use them for compost fodder.    I do the same with comfrey.

It does seem to form a clump but the clump in our plot has stayed at about 2.5 foot square forever so its not like it will take over.

Same with ours.

But does this answer the initial question? I don't believe that it was h/r??

I actually went down today and dug a bit and it was definitely horseradish after all.
