Growing Horseradish

Getting Started

Horseradish (Armoracia rusticana) is a hardy perennial plant known for its pungent roots. It thrives in USDA hardiness zones 3-9 and prefers well-drained soil with a pH of 6.0-7.5. Here’s how to get started:

1. Purchase Fresh Horseradish Root: In mid-winter to early spring, buy a fresh horseradish root from your local grocery store or a garden center.
2. Prepare the Planting Area: If planting in the ground, choose a location with plenty of space as horseradish can spread. Alternatively, use a tall pot filled with well-rotted compost. A section of drainage pipe can help encourage long, straight roots and prevent the plant from taking over your garden.
3. Planting: Cut the root into 2-inch sections and plant them horizontally about 2 inches deep. Water thoroughly after planting.
4. Care: Water the plant regularly, especially during dry spells. Horseradish prefers partial shade, so if you live in a hot climate, place the pot in a shaded area.

Maintenance

• Watering: Keep the soil consistently moist but not waterlogged.
• Fertilizing: Apply a balanced fertilizer in early spring to promote growth.
• Pest Control: Horseradish is generally pest-resistant, but watch out for flea beetles and aphids.

Harvesting

• Timing: Harvest horseradish in late autumn after the leaves have died back.
• Method: Dig up the roots carefully, reserving a few sections to replant for next year’s crop.

Preserving Horseradish

To enjoy horseradish year-round, preserving it is essential. Freshly harvested roots are easier to peel and grate.

Steps to Preserve

1. Scrub and Peel: Clean the roots thoroughly and peel them.
2. Grate: Finely grate the roots. Be cautious as the fumes can be quite strong and irritating to the eyes.
3. Mix with Vinegar, Salt, and Sugar: For every 3 tablespoons of grated horseradish, add 1 tablespoon of white wine vinegar, 1 teaspoon of sugar, and a pinch of salt.
4. Store: Transfer the mixture into sterilized jars, seal, and refrigerate.

Storage

• Shelf Life: Preserved horseradish can last up to six months in the refrigerator.
• Usage: Use it as is or mix with cream, mayonnaise, crème fraîche, or yogurt to create horseradish sauce.

Culinary Uses

Horseradish is not just for beef. It pairs well with:

• Oily Fish: Enhances the flavor of salmon and mackerel.
• Vegetables: Adds a kick to cabbage, potatoes, and coleslaw.
• Condiments: Mix into sauces and dressings for an extra zing.
