my fellow Canuck, for your digging.
There are some good youtube vids that Ive been watching also.
The"Mandys NZ" horseradish link is a good local one but it appears to me that they add sweet mayonnaise which wimps it out.
I was at the CO-OP in Victoria BC last Aug. and got some Cedervale HORSERADICH-RAIFORT manufactured my hometown Toronto and brought some back to NZ, with genuine bilingual label!!
Its basically ground horseradish with vinigar and salt with a touch o`mustard seed.
All my friends love it as its all gone!
Down under, Kiwis are big meat eaters with that good old Beef Eater English tradition so its shocking that they dont have their horseradish act together.
Anyhoo, I think I will leave my plants alone and remain calm re :Plant flowering".
If anyone can add words of wisdom, please chime in.
