Growing horseradish is easy – the tricky bit is stopping it taking over your garden.
In the UK, it grows wild and is easily confused with dock.
Look closely at the photo here on the right.
Horseradish leaves are not as wide as dock leaves and their edges are a bit wavy - so be cautious if you think you have it growing in your garden already.
It is very versatile – not just as a sauce with beef, but it goes well with smoked mackerel, sausages, ham, trout, eggs and avocado. It 'cuts through' oiliness which is why it goes so well with what is considered 'fatty' food.
It also has diuretic and digestive uses and is a natural antibiotic.
If you’re on a low salt diet, then it is really useful as a seasoning.
Horseradish will grow anywhere – and that’s part of the problem;-)
Plant in early spring for harvest that year or autumn for harvest the following year.
Dig out a trench at least 2 feet (60cm) deep – horseradish has extremely long tap roots.
Replace about 15 inches (40cm) of topsoil and then add some compost .
Lay the roots of horseradish on this about 12 inches (30cm) apart and then cover with more soil. Firm in with your heel.
Seed can be sown in early spring – thin plants to 12 inches (30cm) apart.
Keep well watered.
It's not a suitable plant for growing indoors, and there really is no need to do so. You can make horseradish sauce out of the roots to last you through the winter. You can dry the roots and keep them in an airtight jar in a dark cupboard if you want to use them medicinally.
By mid fall (autumn) the roots should be ready to harvest.
Dig up all the plants.
Use the larger roots to make horseradish sauce and store the smaller ones in sand for replanting next year - the size of the smaller roots would be about the thickness of a pencil.
By digging up all the plants, you’ll prevent the horseradish from growing out of control and taking over your garden.
Rescue Remedy for Horseradish
Well, if you’re sure you’ve got horseradish and not dock, then you’ll have to be ruthless and dig up what you don’t need.
You’ll probably have to do that more than once as well the following year – it grows like a weed once it’s established.
Use the larger roots and store the thinner ones in sand for replanting.
You could plant some of the smaller shoots in pots – either give them away or sell them once they start into growth.
