Seeking horseradish seeds looked up EBay and sent away for Russian variety Has stronger flavour and pest resistance is higher. The seeds arrived via Air mail in sealed pack. Be ware the pack of seeds can cover 4m square Each plant can yield 4kg horseradish!! Happy growing!

When to harvest horseradish

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
