We have removed as much as we could but it is growing and spreading anyway. Will roundup kill it? Thanks very much.

When we bought our current home there was a meter-square patch of horseradish. I hate the stuff and wanted to put something else there. I soon discovered how hearty it is. Our neighbour, a woman originally from rural Eastern Europe had a patch of a flowering plant I have come to know of as, 'Obedience Plant'. I didn't take notice of it. Resigning myself to a life of pulling horseradish leaves out I focused on pulling. Soon I noticed the obedience plant coming in and taking over. Now several years later, It is a full patch of obedience plant, only a few horseradish plants left. It seems when I pulled the leaves out it gave the obedience plant the opportunity to grow over the spot and suffocate the roots. The obedience plant has a shallow and slightly broad root-like a duck's foot. It offers a nice arrow shaped flower at the end of summer...but it does get rid of horseradish without glyphosate--which is very toxic.
Round Up will kill it but it is toxic so try dumping a gallon of vinegar with a bit of water over top and it is sure to die.
