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.

Hello Brian, I would say yes, as I have mine planted in a big 42 cm wide pot but did not move it into "winter quarters" as I do with my Kaffir Lime potted tree, it showed no damage over the years, Happy gardening Jen

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
