How to Grow Horseradish
Growing Your Own Horseradish: A Rewarding Garden Adventure
Growing your own horseradish offers more than just a spicy root to enhance your meals. It’s a satisfying way to connect with your garden, add hardy greenery to your landscape, and enjoy the pride that comes with harvesting fresh horseradish you grew yourself.
Getting Started with Horseradish
Before planting horseradish, it’s important to plan carefully for the best results. Choose a location that gets full sun to partial shade and has rich, well-draining soil. Horseradish prefers loose, loamy soil but can adapt to various types if properly amended.
Space is another factor—horseradish spreads aggressively underground via its roots, so give each plant enough room (at least 18–24 inches apart) to grow without overcrowding. Because horseradish is typically grown from root cuttings (called “sets”) rather than seeds, pick healthy, disease-free roots for planting.
Caring for Your Horseradish Plants
After planting, consistent care helps your horseradish thrive. Water regularly to keep the soil evenly moist but not waterlogged, especially during dry spells. Mulching can help retain soil moisture and reduce weeds.
Fertilizing is beneficial, too—adding compost or a balanced fertilizer in early spring encourages vigorous growth. Horseradish is a tough perennial, but removing any damaged or weak foliage will help the plant focus energy on producing strong roots.
Keep an eye out for common pests like flea beetles or diseases such as fungal leaf spots. Early intervention and maintaining good garden hygiene will keep your plants healthy and productive.

Acclimating Horseradish Roots Before Planting
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Before your horseradish roots take their place in the soil, there’s an important step to help them settle in well: acclimation. This process gently prepares your horseradish root cuttings (also called “sets”) for the transition from storage or greenhouse conditions to the garden.
At 1st Choice Fertilizer, our horseradish root sets may come from cool storage or greenhouse environments where humidity, temperature, and light are controlled. These conditions are great for preserving roots but can leave them vulnerable when first exposed to outdoor elements.
Why Acclimation Matters
Fresh horseradish roots can be sensitive to sudden changes in temperature, sunlight, and moisture levels. Without a proper acclimation period, your root sets risk drying out, rotting, or developing stress that slows growth after planting.
Environmental factors that can harm unacclimated horseradish roots include:
-
Freezing or near-freezing temperatures
-
Intense direct sunlight
-
Dry, windy conditions
-
Excess moisture causing rot
These conditions are common in early spring or late fall—typical planting times for horseradish—and can shock new root sets.
How to Acclimate Horseradish Root Sets
If you’re planting roots fresh from storage:
-
Bring them out of cold storage a few days before planting.
-
Keep them in a cool, shaded, and well-ventilated area, avoiding direct sun or heat.
-
Check the roots daily to make sure they aren’t drying out or molding. Light misting can help maintain moisture without soaking.
If your roots come potted or bagged with some shoots:
-
Place them in a sheltered, partially shaded spot outdoors for 2–3 days.
-
Gradually increase sun exposure, moving from shade to dappled sun to morning sun.
-
Water lightly to keep soil moist but not soggy.
-
Protect from strong winds and frost, bringing indoors if temperatures dip below 40°F.
Timing Your Planting
Once your horseradish root sets have adjusted—usually within 2–4 days—and soil temperatures are steadily above 40°F, they’re ready for planting. Choose a cloudy day if possible to reduce transplant stress.
Additional Tips
-
Adapt to your climate: Colder regions may require longer acclimation indoors or in a protected area.
-
Avoid rushing: Even though horseradish is hardy, gentle preparation pays off in better root establishment and growth.
-
Storage check: Before planting, discard any root sets that feel mushy, dried out, or have visible mold.
Taking the time to acclimate your horseradish roots before planting helps ensure strong, healthy plants that will thrive and provide flavorful roots for years to come. With 1st Choice Fertilizer, you’re setting your garden up for success from the very start.
Choosing the Right Location to Plant Horseradish
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Great horseradish starts with choosing the perfect spot in your garden. Picking the right location will help your horseradish roots grow large, healthy, and flavorful—while making your growing experience easier and more rewarding.
Here are five important factors to consider before planting horseradish:
-
Sunlight and Soil Quality
-
Space and Spread
-
Drainage and Moisture
-
Surroundings and Competition
-
Room for Future Harvests
1. Sunlight & Soil: Bright and Loose
Horseradish thrives best in full sun to partial shade, ideally receiving 4 to 6 hours of direct sunlight daily. While it tolerates some shade, more sun usually means stronger, thicker roots.
Good soil is just as crucial. Horseradish prefers well-drained, fertile, and loose soil with plenty of organic matter. Heavy clay soils can cause roots to become stunted or misshapen, while sandy soils may dry out too quickly. If your soil is compacted, loosen it with a garden fork or add compost and organic amendments like 1st Choice Fertilizer to improve texture and fertility.
2. Space & Spread: Room to Grow Wide
Horseradish roots can spread aggressively underground, so giving them plenty of space is essential to avoid overcrowding and competition. Ideally, plant root sets at least 18 to 24 inches apart in rows spaced about 24–30 inches wide.
Because horseradish can spread by root fragments, it’s a good idea to contain it in a dedicated bed or use barriers to keep it from invading neighboring plantings.
3. Drainage & Moisture: Avoid Standing Water
While horseradish likes consistent moisture, it doesn’t tolerate soggy soil or standing water well. Poor drainage can lead to root rot and other diseases.
Choose a planting site with good drainage and avoid low spots where water pools. If drainage is a concern, consider planting on a slight raised bed to help excess water flow away from the roots.
4. Surroundings & Competition: Keep It Friendly
Avoid planting horseradish near large trees or aggressive shrubs whose roots might compete for nutrients and water. Also, keep horseradish away from plants with shallow roots that could be disturbed by its spreading roots.
Since horseradish leaves can grow tall (up to 3 feet), make sure it won’t shade out smaller nearby plants or block pathways.
5. Room for Future Harvests: Plan for Success
Horseradish is a perennial crop that can come back year after year if well cared for. Plan your bed or garden area with future harvests in mind—leaving space to divide or expand your plants over time.
A dedicated horseradish patch makes it easier to manage and harvest robust roots season after season.
Ready to Plant?
Choosing the right spot will set your horseradish roots up for strong, vigorous growth and a bountiful harvest. With good sunlight, fertile soil, and plenty of room to spread, plus support from 1st Choice Fertilizer, you’re well on your way to growing flavorful horseradish right at home.
How to Plant Horseradish the Right Way
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Growing robust horseradish starts with planting it correctly. Though horseradish is generally hardy and low-maintenance, giving it a solid start in the right spot and with proper technique will pay off in big, flavorful roots year after year.
Getting Started: Prep Before You Plant
If you’re planting horseradish root cuttings, soak them in water for 1–2 hours before planting to help jumpstart root growth. Avoid letting the roots dry out or freeze before planting.
Step-by-Step Planting Guide
Dig Deep & Wide
Prepare a loose, deep bed or trench about 12–18 inches deep and wide enough to comfortably fit the root cuttings without crowding. Horseradish roots grow downward and spread laterally, so give them room to expand.
Enrich the Soil
Mix aged compost or well-rotted manure into your garden soil to provide nutrients and improve texture. Adding coir or peat moss (such as our Coco-Fiber Growing Medium) can also help retain moisture while maintaining good drainage.
Plant Root Cuttings
Plant horseradish root cuttings (also called sets) about 2–3 inches deep with the buds facing upward. Space them 18–24 inches apart to allow for healthy root spread.
Water Thoroughly
After planting, water deeply to settle the soil around the roots and provide initial moisture. Keep soil evenly moist—not soggy—throughout the growing season.
After Planting: Care and Maintenance
-
Mulch: Apply 2–3 inches of organic mulch like straw or wood chips to conserve moisture, suppress weeds, and regulate soil temperature.
-
Watering: Keep soil consistently moist, especially during dry spells, but avoid waterlogging.
-
Fertilizing: Feed your horseradish patch in early spring with a balanced fertilizer such as 1st Choice Fertilizer’s Veggie Booster to promote vigorous root growth.
-
Containment: Because horseradish can be invasive, consider using root barriers or planting in a dedicated bed to control spread.
Special Note on Harvesting
Horseradish is typically ready for harvest in late fall or early spring after a full growing season. Dig carefully around the plant to lift the large, flavorful roots.
You’re Ready to Grow Strong Horseradish!

How to Prepare Soil for Planting Horseradish
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Before your horseradish roots go into the ground, proper soil preparation lays the foundation for healthy, vigorous growth. Rich, well-prepared soil encourages strong root development—which is essential for producing large, flavorful horseradish roots.
Whether planting in early spring or fall, preparing your soil ahead of time ensures your horseradish has the nutrients and structure it needs to thrive. Here’s what to keep in mind.
Why Soil Preparation Matters
Healthy soil helps your horseradish plants to:
-
Absorb essential nutrients for root growth
-
Maintain consistent moisture without waterlogging
-
Develop deep, robust roots for a strong harvest
-
Resist pests, diseases, and environmental stress
We recommend testing your soil before planting and again yearly. Use our 1st Choice Digital Soil Meter for quick checks or send a soil sample to your local Cooperative Extension for detailed analysis.
Understanding Soil Types
Knowing your soil type guides what amendments you’ll need:
-
Clay or Silt Soils
Dense and heavy, these soils hold moisture well but can become compacted, restricting root growth and air circulation. -
Loam Soils
The ideal choice for horseradish—loam is nutrient-rich, drains well, and holds moisture evenly. -
Sandy Soils
Fast-draining but poor at retaining water and nutrients, sandy soils require organic matter to improve moisture retention.
When to Prepare the Soil
Prepare your horseradish bed when the soil is workable—typically early spring or fall. Starting in the fall allows amendments to integrate into the soil before planting.
What to Add to Your Soil
Horseradish thrives in nutrient-rich, loose soil. Consider these amendments:
-
Compost: Boosts soil fertility and improves moisture retention.
-
Well-Rotted Manure: Adds nutrients and organic matter to feed your plants.
-
Coir or Peat Moss: Helps sandy soils retain moisture while improving texture.
-
Garden Lime: If your soil is too acidic (pH below 6.0), lime can help balance it.
-
Sand: Use sparingly to loosen compacted clay soils, combined with organic matter.
Pro Tip: Don’t overlook natural yard waste like shredded leaves, grass clippings, or kitchen scraps. These break down into valuable organic matter over time—start collecting in fall for spring use.
How Organic Matter Helps Different Soils
-
In sandy soils: Organic matter binds soil particles, improving water retention and nutrient availability.
-
In clay soils: It loosens heavy soil, enhancing drainage and root penetration.
-
In poor soils: Organic amendments restore microbial life, increasing nutrient uptake and soil health.
Your Soil, Your Success
Good soil prep is one of the best investments for a thriving horseradish patch. With nutrient-rich, well-structured soil, you’ll enjoy bigger roots, fewer problems, and a more satisfying harvest.

Fertilizing Horseradish for Healthy Growth and Robust Roots
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Fertilizing horseradish is one of the best ways to improve soil health and give your plants the nutrients they need for strong, vigorous root development—the part you’ll harvest and enjoy. Proper nutrition supports leafy growth while also encouraging large, pungent roots full of flavor.
But not all horseradish plants need the same amount or type of fertilizer. That’s why testing your soil before planting or fertilizing is key to applying the right balance for your garden’s unique conditions.
Why Fertilize Horseradish?
Fertilizer isn’t just “plant food”—it supplements your soil with essential nutrients that horseradish needs to thrive, including:
-
Nitrogen (N): Fuels lush leafy growth, which in turn helps the root grow strong
-
Phosphorus (P): Encourages healthy root development and overall plant vigor
-
Potassium (K): Improves disease resistance and root quality, enhancing flavor and storage life
You’ll find these as N-P-K on fertilizer labels, including our 1st Choice Premium Fertilizer blends—formulated for root crops like horseradish.
Always Test Before You Fertilize
Soil nutrient levels vary widely, and over-fertilizing can cause excessive leaf growth with poor root development or increase pest problems. We highly recommend testing your soil with a 1st Choice Digital Soil Meter or sending a sample to your local Extension office.
Once you understand your soil’s nutrient profile, you can select a fertilizer that delivers the right balance—whether a slow-release organic option or a water-soluble mix for quick uptake.
Fertilizing Young Horseradish Plants
If you’re planting horseradish in well-prepared soil rich in organic matter, you may not need additional fertilizer immediately. But if you notice slow growth or pale leaves, a nitrogen-rich boost in early spring can help.
Our 1st Choice Root Crop Starter formula is an excellent water-soluble fertilizer that promotes healthy leaf and root development in young horseradish plants.
Fertilizing Established Horseradish
As horseradish plants mature and the roots begin to bulk up (usually the second growing season), they benefit from balanced feeding with slightly higher phosphorus and potassium to support root size and quality.
Apply a balanced fertilizer like 1st Choice Root & Vegetable Granules around the plants in early spring and again mid-season for best results.
When to Fertilize Horseradish
-
First application: Early spring, when growth begins
-
Second application: Mid-season (about 6–8 weeks later)
-
Avoid late fertilizing: Stop fertilizing at least 6 weeks before harvest to encourage root maturity
Important Fertilizing Tips for Horseradish
-
Avoid too much nitrogen late in the season, which encourages leafy growth at the expense of root size.
-
Incorporate organic matter such as compost or well-rotted manure before planting for long-lasting fertility.
-
Keep soil moist but well-drained to maximize nutrient uptake.
Micronutrients Matter
In addition to N-P-K, micronutrients like magnesium, calcium, and iron are important for horseradish leaf health and root quality. Deficiencies may show as yellowing or spotting on leaves.
If needed, supplement with products like 1st Choice Earth-Care Micro Mix to maintain balanced nutrition.

Watering Horseradish
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
Horseradish is a hardy root crop that generally adapts well to a variety of soil conditions. However, consistent and appropriate watering is essential—especially during establishment and root development—to produce vigorous, pungent roots.
Watering Needs for Horseradish
If your horseradish is planted in garden beds with typical soil moisture levels and moderate rainfall, supplemental irrigation may not be necessary after the first season. But for young plants or in dry climates, maintaining adequate soil moisture is critical.
Using a product like 1st Choice Fertilizer can improve soil health and moisture retention, helping roots access water longer and reducing the frequency of irrigation.
Watering Tips for New Horseradish Plants
During the first growing season, aim to keep the soil evenly moist but not waterlogged around the root zone. Horseradish roots grow best when soil moisture is consistent but drains well.
-
If your region receives about 1 inch of rain every 7–10 days, natural rainfall usually suffices.
-
In drier conditions, provide a deep, slow watering every week or 10 days to encourage roots to grow downward.
-
Using soaker hoses or drip irrigation near the base allows water to penetrate deeply with minimal runoff or evaporation.
-
Avoid frequent shallow watering which encourages surface root growth and can stress the plant.
Important Considerations
-
Horseradish prefers well-drained soils; excessive watering or poor drainage can cause root rot or other fungal issues.
-
In cooler climates or heavier clay soils, watering every 10–14 days may be enough.
-
If you create a shallow basin around your plants to help capture water, level it out before frost to avoid ice buildup and potential crown damage.
-
Observe your soil moisture regularly by feeling the soil a few inches down—adjust watering frequency as needed to keep the root zone moist but not soggy.
Water Use and Local Restrictions
Be mindful of any local water-use regulations, especially during drought or dry seasons. Following regional restrictions ensures sustainable gardening practices and helps conserve water resources.
By balancing adequate moisture with good drainage, your horseradish plants will develop strong roots and healthy foliage, setting the stage for a flavorful harvest.
Enjoying the Fruits of Your Labor: Horseradish Harvest and Storage
(From the “How to Grow Horseradish” Series by 1st Choice Fertilizer)
After months of nurturing your horseradish plants, the time comes to reap the rewards—harvest! With proper timing and handling, you can enjoy fresh horseradish root or store it for months of flavorful use.
When Will My Horseradish Be Ready to Harvest?
Horseradish typically takes about 1 to 2 full growing seasons to develop mature roots, depending on your climate and care. Most gardeners harvest in late fall, after the first frost, which helps sweeten and mellow the root’s pungency.
Recognizing Mature Horseradish Roots
