A Detailed Guide to Horseradish (Wasabi Radish) Cultivation Techniques

Horseradish is native to Europe. It is a raw material for seasoning and also a vegetable. In recent years it has gradually been cultivated domestically. Today, the editor will introduce horseradish cultivation techniques to everyone.

1. Seed and site selection

First, we must select good horseradish seeds without obvious wounds and free of pests and diseases, and choose high-lying, dry soil with high fertility as the planting site. Before planting, the land preparation work must be done well. First, plow the soil deeply to about 35 cm, form ridges and disinfect them, then apply sufficient base fertilizer. The base fertilizer is mainly farmyard manure, combined with a small amount of compound fertilizer, and then plant it on top of the ridges. The planting period for horseradish is relatively long. Generally, planting is carried out around the Beginning of Spring each year. When sowing, control the sowing density well and ensure sufficient soil moisture. After sowing, cover with about 4 cm of soil and cover well with plastic film.

2. Timely planting

The planting time for horseradish should be chosen in spring and autumn, because the temperatures in summer and winter are too extreme and not conducive to the growth of horseradish. Usually the best planting time is around Qingming Festival each year. Dig planting holes on top of the ridges, control the density and depth well, and keep the planting holes at an incline of about 45 degrees to the ground. After planting, cover with fine soil, smooth and refine the top of the ridges, spray an appropriate amount of herbicide, and cover well with plastic film. The plastic film must be firmly secured, pressed tight and compacted to prevent it from being blown away by the wind. If planting by sowing, small holes should be made in the plastic film, and then the small holes should be covered with soil, which is beneficial for seed germination and seedling emergence.

3. Thinning and filling in seedlings

If horseradish is sown and planted in spring, under normal management it will break through the soil in about one month. During the seedling stage, because the spicy taste of the roots has not yet fully developed, it is relatively vulnerable to pests and diseases. After seedling emergence, we should regularly observe the growth of the seedlings. If weak seedlings damaged by pests and diseases or dead seedlings are found, they should be removed in time, and then healthy horseradish seedlings should be replanted. When the seedlings grow to a certain height, the thinning work should be done well, and then the ridges can be closed and the seedlings fixed.

4. Fertilization management

Horseradish has a relatively large demand for fertilizer during growth. When the seedlings grow to about 12 cm, the first topdressing work needs to begin. At this stage, the fertilizer is mainly urea, with the purpose of promoting seedling growth and increasing the growth rate. Then comes early summer. Early summer is when horseradish has the strongest growth capacity and a very large demand for nutrients. At this time, nitrogen, phosphorus and potassium compound fertilizers such as urea and potassium sulfate should be applied as topdressing to promote plant leaf growth, strengthen photosynthesis, and increase nutrient accumulation.

The above is the horseradish cultivation techniques introduced to you by the editor. I hope it can help you!
