Horseradish belongs to perennial plants, but it can be grown in one place for no more than 3 years, because after this period the plant becomes stiff and not so tasty.
In spring, horseradish is more burning and bitter: there are more phytoncides and substances responsible for bitterness in the rhizomes. In September, October, November, the content of sugars and nutrients is maximum, but the severity decreases.
If you decide to dig horseradish in the fall, then the best time for this is the third decade of November.
Horseradish is quite picky about the soil. Best of all, it will grow on well-fertilized sandy and loamy soils with a neutral or slightly acidic reaction.
Lighting: bright sunlight. Soil: fertile loamy, sandy and chernozem soils. Watering: regularly, spending from 10 to 20 liters of water per 1 m² of beds. In a season with normal rainfall, horseradish can not be watered.
Cut off the top third or half of the root (sending the rest to the kitchen), and root the bottom part in the garden. To do this, loosen the soil to a depth of 30 cm and add a shovel of well-rotted compost. Now plant the root cutting at a 45 degree angle so that the top of the cutting is 2 inches below the soil line.
When growing horseradish, it is recommended to remove flower stalks so that the rhizomes are not woody. For decorative purposes, horseradish is grown specifically for the sake of flowers. White lush inflorescences rise to a height of one and a half meters and are quite suitable for the background of the flower bed.
