Hi Jan, Try www.theseedvault.co.za. They sell horseradish rhizomes (pack of 3 for R60). I bought some recently and they were excellent quality.

Can grow in partial shade but most plants need sunlight. A good watering once a week will probably do, Doesn't like too wet.

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
