I'm planting horseradish, what plants should not be planted next too it?
There's no plant that I know of that will suffer being planted next to Horseradish but you will need to give your Horseradish plenty of space as it will grow large,spread above ground and also root extensively below ground.


I would therefore plant any other perennial herbs next to it since you will not be disturbing the plant when pulling out annuals at the end of the growing/flowering season.
Reply:I think it would depend on "HOW" you are planting the horseradish. There is an extensive thread on horseradish on davesgarden.com. We are planting it for the first time this year also, and are ful of questions. They talk about planting it in PVC pide to prevent excessive spread and to promote single large roots. Check it out and good luck.
Reply:PVC doesn't work. I tried. The roots went to the bottom, curled up, and surfaced. I just rototill what I don't want. Still, some comes back, but I cook with the leaves to kill THAT root. I looked for 3 years to find good stock. You will love it. They also are planted next to wild onions. They grow on the surface and never get disturbed.
Reply:Bearbrain has the size issue right but I wouldn't worry about their roots being disturbed, that's the point, those hot delicious roots to be dug after the first hard freeze. I also grow them as ornamentals for the texture and size of there leaves. For maximum leaf and root size remove the nondescript flower heads before they bloom. They are voracious eaters so feed, feed and feed. They are also flea beetle magnets so even if you don't like horseradish plant a few to take the pressure off other susceptible plants until your garden acquires the necessary predators or spray, spray and spray with the pollutant of your choice. Be careful not to get them too close to perennials who's roots might be disturbed during harvest and remember all the little root pieces (pips) will produce new plants in the spring. I'm sure there are "companion planting" guidelines out there but I'm not up to 'speed' on them. RScott
