Cultivation

Horseradish is widely distributed through the temperate zone, mainly as a result of cultivation, and can also be cultivated at elevations above 1,000 metres in the tropics. It grows best in areas where annual daytime temperatures are within the range 14 - 20°c, but can tolerate 6 - 28°c. When dormant, the plant can survive temperatures down to about -15°c, but young growth can be severely damaged at -1°c.
