Horseradish
Armoracia rusticana
Horseradish is a cold-hardy perennial root vegetable suited to Zones 3-9, thriving in deep loamy soils with winter dormancy. It is propagated from root cuttings and requires minimal inputs once established, though its aggressive spreading habit requires careful management. Commercially viable as both fresh-market roots and processed condiments.

Overview
Horseradish is propagated vegetatively from root cuttings (sets) 6-8 inches long, planted at a 45-degree angle with the top 2 inches below the soil surface. Spacing is typically 24-30 inches within rows and 30-36 inches between rows (~8,700 sets/acre). The crop thrives in deep, rich, moist loamy soil and benefits from 100-200 lbs N/acre depending on soil type. "Lifting" (pulling plants partway out of the ground in midsummer to strip side roots) produces smoother, higher-quality roots. Harvest occurs after a hard frost when the top growth dies back; roots are dug with a subsoil plow. The plant is extremely persistent and difficult to eradicate once established — all root fragments can regenerate. Commercial plantings are often managed as annuals (replanted yearly) to maintain root quality, though the plant is a long-lived perennial.

Equipment Requirements
planting
Deep loosening to 8-10 in ahead of planting sets, incorporating organic matter.
Sets are planted at an angle 3-5 in deep; specialized set planters used on commercial acreage.
cultivation
Shallow cultivation for early-season weed control before canopy closes.
Roots are sometimes lifted and side-roots removed ("lifting") mid-season to grow a single straight main root.
irrigation
Supplemental water for root sizing in dry spells; drip preferred to keep foliage dry.
spraying
Foliar insecticide/fungicide applications for flea beetle and leaf spot control.
harvesting
Tops are mowed off before digging to allow mechanical lifting.
Undercutting root digger lifts the deep taproots at harvest.
post_harvest
Roots are washed to remove soil before grading and storage.
Roots stored near 0 C at high humidity to hold quality for processing.

Known Risks
pest
Flea beetles are a serious foliage pest, chewing shot-hole damage in leaves and reducing photosynthetic area on young plantings.
As a brassica, horseradish hosts caterpillar defoliators that skeletonize leaves in mid to late season.
Grub-like larvae tunnel into roots, causing forking and downgrading of marketable root quality and yield.
disease
Fungal leaf spots defoliate plants under prolonged wet foliage, cutting root sizing late in the season.
White pustules on the underside of leaves distort foliage and reduce vigor in humid conditions.
A phytoplasma/leafhopper-associated disorder causing internal root browning and brittleness that renders roots unmarketable.
Roots rot in saturated soils, especially on heavy or poorly drained ground.
weather
Alternate freeze-thaw can lift shallow sets and roots left for spring dig.
Roots are dug in late fall to early spring; a locked, deeply frozen soil profile can close the dig window.
market
Commercial demand is dominated by a small number of grated-root processors, limiting price competition for growers outside established supply chains.
regulatory
Horseradish spreads aggressively from root pieces left in soil and can become a persistent volunteer in rotation ground.
Nutritional Yield
Nutrition data pending.
Research agents will profile Horseradish against USDA FoodData Central on the next maintenance pass. Per-acre nutritional yield will appear here once the per-100g panel is recorded.
