Hi Lori. from my experience with horseradish you certainly can grow H. from a root cutting. Beware horseradish can become invasive so plant in a large pot and bury in the garden. this should contain the roots. I am having trouble removing horseradish from a large garden bed. every time the bed is dug a piece breaks off and away goes the h.radish again!!! good luck.

I am also interested also in how to grow it and how to obtain it.

Gail I purchased a plant at flowerpower a few years ago and planted it in the ground and left it alone until about may- I then pulled it out and cut the root into small pieces about 5cm each and put it back into the ground. It grew and the plant has large green leaves - you can begin to use it in the second year. I pull one out - grate what I need and put it back into the ground. I am sure you will be able to buy it on eBay as well.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
