I too have been looking for horseradish. Isabel Sheppard sold me some when we lived on the Sunshine Coast but it died and anyway, you cannot bring plants to Tas.

Head to Chung Sing's vegetable wholesaler in Campbell St and you can buy some if in stock otherwise they can ring the supplier and order some in. Transplant that.

If it is celcius, then yes, otherwise, "Best planted at soil temperatures between 50°F and 77°F."

I have grown ordinary radishes, but one is very long, not round like t he ot hers. How do I know if t his is a horseradish please

Iris, horse radish is a completely different plant. It would be unusual if you had some seeds as they are usually grown from cuttings. What you might have is a daikon radish. They grow a long white root.

I have it growing out of control in SW Victoria

Ted, Would you be interested in selling some horseradish roots to me? If so, about how many could you supply and approximately at what price?Jan

Ted, with all these people wanting horseradish plants,you should consider filling this need with your 'out of control' supply. Plants will grow from apiece of root, so it shouldn't be difficult to send thru the post.Root cuttings are planted in early autumn.
