Where can I buy fresh horseradish? I bought several plants from my local nursery (wyee) but they are not ready for consuming for several months yet.

I'm from Centurion and had some horseradish plants. They died towards the end of 2015 in the drought but I managed to save a plant that is now doing well again. Make a note and contact me in August 2016 and I will give away some roots to start with in the new growing season. First-come-first-served. e-mail: [email protected]

I have been looking after a friends plants. One of them was a horseradish plant in a pot. Just one little frail leaf. It did not last. So will I be able to get a replacement now from a nursery? I live in inner city Sydney

I live in inner city Sydney and planted horseradish in potting mix in a pot at the back of the pot section on my west-facing balcony in about June (?). I've pretty much left it alone except for an occasional water if it's been particularly dry. The leaves have grown well - they were pretty lush before though I've noticed now that they're a bit torn - whether this is from an insect or from a few hailstorms I'm not sure. Thing is... I have no idea when to harvest them. How do I know if they're ready to be pulled up and used? And can I just pull up one leaf/plant and leave the rest in the pot? Also, I'm experimenting now but I really want to have some fresh root available in March/April next year. Do I have to replant at a particular time? Can I leave the current plants in the pot until then? etc

Hi Jackie, I know it was a long time ago, but do you still have any horseradish in Launceston ? I am in Beaconsfield and would love to grow some so I can make Fire Water with it. Donna.
