Irrigation of horseradish

Horseradish is a plant that must be watered regularly. We can grow it in all regions of Italy but it is important to avoid letting it face long periods of drought. For a domestic cultivation we can wet by hand simply with the help of the watering can. For larger crops, instead, it will be necessary to install a fixed irrigation system that guarantees the right water supply. Respecting the seasonality we will progressively increase the interventions as the more intense heat arrives. In the spring, for example, it may be necessary to water 2 times a week and, if it rains often, sometimes it is not really necessary. The important thing is that the water is never missing and that the soil is always moist. Watering will be more intense and frequent if we put the horseradish plant in a sunny place.

How to cure the horseradish plant

Horseradish, if it can find the ideal habitat, is even a pest. In this case the treatments would be really reduced to the minimum being more than enough to remove the weeds from time to time and periodically refresh the soil with a superficial weeding. It does not need supports to grow and resists weathering quite well. Horseradish should be sown like the potato, buried for at least 8cm and spacing the plants by 35cm. We will be able to complete the horseradish cultivation evenly filling the garden areas, simply renewing the plants, picking up the old ones and obtaining new ones from the division of the tufts. They will sprout with ease and soon they will grow together with the others. In general, no special care is required.

Soil and fertilization

Horseradish loves damp and loose soils. If the roots can easily spread, the horseradish will also multiply spontaneously. It does not need a particularly rich soil but if we doubt that our garden is too dry, we can resort to preventive fertilization. We will prepare the earth with a dig, reaching at least 35cm in depth. Then we will proceed with enrichment with organic fertilizer or home compost. Then we will cover everything with earth or universal soil. Horseradish can be planted when the soil has absorbed nutrients. No further fertilization should be necessary, apart from some well-decomposed home compost that can be added periodically. Mulching can be useful for the development of the horseradish plant.

Horseradish: Exposure and climate

Horseradish is a fairly strong plant that tolerates a fairly rigid climate. It can be cultivated at hilly levels, preferring the fresh and above all an environment characterized by sufficient rainfall. It can also withstand short periods of fairly intense heat but in this case it is important to try not to vary the degree of humidity too much, perhaps by protecting the base of the plant with a mulch made of lawn or garden grass clippings and barks. It does not necessarily have to be put in full sun and can grow even in areas of partial shade. Like all plants it can be attacked by pathologies and parasites, although in general it is not necessary to use pesticides or chemical products that are better avoided. Herbal decoctions are more than enough to keep pests away.
