Wasabi Japanese Horseradish roots (Holbeach St Marks PE12)

Plant from garden centre originally so not the same as hedgerow wild Horseradish. Now growing in ground.I can no.longer dig roots up to freeze to make sauce due to being ancient. Aso great to go with sushi. Or grow some yourself but in a pot! Oh yes...feel free to come and dig as much as you want.
