Due to the many requests I have received for horseradish, I can no longer supply any more just yet as I am still trying to get most of my young plants established. Many thanks

Most European/Italian greengrocers will have it just now.Bought 100gm Tues.@$39.00 p kg. Most to grow in old holey buckets, H/radish can dry out quite quickly if not mulched. Keep eyes on leaqves, some pest find them quite yummy. Keep healthy.

Yes, ours certainly seems to be stronger after a second year but the roots are very spindly and they are not easy to peel. Any tips on growing a thicker root? However, to make the sauce and not being too keen on hand grating, I first grated the root with the food processor. This gave thin matchsticks but also lots of lumps, then I added some vinegar and used the chopper to cut it finer and it worked well. I also added some hot mustard to give it a bit more zing.

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
