Horseradish is grown from root cuttings. If you know someone who has it in their garden, just one piece of root will start off for you.

Dig a deep hole and refill with compost as the horseradish has a long taproot. Plant it and then leave it alone. Apart from constant wet or cold, horseradish will grow in any part of the garden.

Horseradish is an aggressive grower and will quickly take over the garden. It will also grow well in a deep container or sink an old bucket in the ground to prevent spreading. Otherwise, remove all the plant when you harvest it and save one piece to replant.

Can be planted in early Autumn or Spring

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

To get the hottest flavor when preparing horseradish root: DO NOT add vinegar while grinding the root! If you're using a food processor, add water, just enough to get it to grind well. Once it is fully ground, let it sit for about 5 minutes. THEN add vinegar. During the 5 minutes, the horseradish (once ground) undergoes a chemical reaction that makes it much stronger. The reaction is (I believe) with water, triggered by breaking up the cells. Vinegar stops this reaction; if you do it too early, the heat never develops. But after a few minutes, without vinegar, the heat will start to fade, so you add vinegar
