Put some roots in a plastic sandwich bag. Then post in a padded post bag. Mine are growing like crazy in big terracotta pots on a unit balcony. The cuttings arrived form the Bowral area very safely.

I bought my horseradish root through Greenharvest.They have a list of edible spring plants that they sell from July each year - They currently have no horseradish available, but they did say that this year the crop wasn't very good. Maybe try again next year if you haven't found some by then?....

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.
