I have got a huge bunch of horseradish roots that desperately need to get planted pronto. Ditto a huge amount of potatoes that have already been chitted. I read that horseradish supposedly helps protect from potato blight. Anybody had any experience planting them in close proximity? I have some 4-square raised beds that are ready to plant and the height of the horseradish at the back of the beds would make (maybe) and interesting "hedge" of sorts. Also would be easier to keep them from invading other areas if planted in these particular beds. What say you guys? Catharine/Atlanta, zone 7b
