Growing Horseradish: Tame Your Allergies And Harness Congestion

Horseradish is a perennial herb (it lasts for several years) originating from southeast Europe. Its tough twisted root is used in cooking to make horseradish sauce, a tangy and peppery sauce used to accompany fish and roast meat.

Horseradish is a voracious grower and has a tendency to take over the garden. It grows well in full sun or partial shade, and should be grown in a permanent spot. It will also grow well in a deep container (this can be advantage as it prevents the herb from spreading).

Growing Horseradish – Gardening Basics

Horseradish is best grown from a single piece of root. Plant the root in early spring or in autumn, in a well-prepared spot that’s free from weeds. Dig a hole 30cm deep and mix in some organic matter such as compost or well-rotted manure. Place the root at a 45-degree angle in the hole and cover with soil, watering well

After a few weeks, shoots and leaves will start to emerge from the soil. Keep the soil moist and free from weeds. Once the plant has developed large leaves it shouldn’t need much attention. The leaves will block light from weeds and suppress their growth; the root should be deep enough to absorb water from deep below the soil’s surface. However if conditions to get very dry, a good drink will promote strong growth.

To stop it getting out of hand (it can become invasive), you should lift all the plants in October after the first frost. You can store the roots in sand, using the larger ones in the kitchen, and replanting the smaller ones the following spring. Alternatively you can grow it in a deep container filled with John Innes No 2 compost.
