Why Grow Horseradish?

Horseradish packs a punch—it's that unexpected, fiery zing we love. Once you’ve tasted fresh horseradish, store-bought pales in comparison.

It's a hardy perennial, which means it comes back year after year. Low maintenance for such high rewards!

According to the USDA, horseradish can grow in a wide range of zones, typically 3-9.

Starting with the Roots

Begin with root cuttings, called sets. You can find them at nurseries or even online.

Make sure your sets are healthy, about six inches long, and as thick as a pencil.

Pro Tip: Plant the sets at a 45-degree angle in well-drained soil to prevent waterlogging.

Planting Time

Sow in early spring, once the soil is workable. Horseradish loves cool weather to start.

Space sets about 18 inches apart to give them room to spread. They grow large!

Soil and Sun Requirements

I find that horseradish does best in rich, loamy soil with a neutral pH. Add compost if your soil needs a boost.

Full sun is preferred, but a little shade won’t hurt. Too much shade, though, will result in less pungent roots.

A study from the University of Illinois says full sun encourages more volatile oils—what gives horseradish its kick.

Watering Strategies

Keep the soil evenly moist but not soggy. Let the top inch of soil dry out between waterings.

Once established, horseradish is fairly drought-resistant, but don’t let it wilt excessively.

Managing Pests and Diseases

Horseradish is generally pest-resistant. However, watch out for white rust and cabbage worms. Remove infected leaves to control spread.

  1. Prune off any yellowing leaves to maintain plant health.
  2. Use organic insecticidal soap if pests become problematic.
In my experience, companion planting with garlic deters most pests.

Harvesting Your Zesty Bounty

The roots are ready to harvest after the first frost in the fall. Grab a digging fork and lift them gently.

Harvest only a portion, leaving some root pieces to regenerate for next year. This way, you’ll always have a fresh supply.

Clean the roots thoroughly, then store them in a cool, dark place. They can last for months!

Preparing Your Fresh Harvest

Peel and grate the roots as needed. Grating releases the volatile oils for a fresh, zesty experience.

To preserve, mix with vinegar immediately. The longer it sits, the hotter it gets!

I learned quickly: use a well-ventilated space when grating. The fumes are no joke.

Enjoy your homegrown horseradish in sauces, spreads, or even cocktails. It’s worth every bit of effort!
