Horseradish is a very popular seasoning in Russian cuisine. It is used both in cooking and in folk healing, since the leaves and horseradish root can cure many ailments. But the decision to grow this extremely useful vegetable on your personal plot often leads to an extremely unpleasant situation - it grows and fills with itself those places where it is completely unnecessary. In this article, we will find out why horseradish can grow so much, why you need to deal with it and what difficulties may arise in the process, how to get rid of horseradish in the garden once and for all, as well as about preventive actions aimed at avoiding problems with the plant in the future.
Why is it growing so much?
Horseradish rhizomes go both deep and sideways in several directions. The root system is very powerful, filled with a huge number of dormant buds. Cutting a piece of root with a shovel or digging up the soil, it is easy to transfer part of the shoots to another corner of the site. The next year we get several bushes - a new one will grow from each cut. In width, the horseradish root system extends up to seven meters - and it is very tenacious, easily tolerates both frost and drought.
Why do you need to remove from the site?
If the overgrown bushes are not removed in time, and even more so to allow the flowering and spread of seeds, horseradish literally fills the whole garden, displacing all other crops. Its large, wide leaves create extensive shade, and a powerful root system sucks out all nutrients from the soil, giving no chance to less tenacious neighbors in the area. For several years wild horseradish is able to destroy almost everything that grew in the garden.
Reasons for possible difficulties in the struggle
It's hard to get rid of horseradish with simple digging and weeding - standard weed control methods. Even in a two-year-old plant, the root system spreads very deeply and widely. It is almost impossible to dig up the entire root. There will definitely be at least one shoot, from which a new bush will subsequently grow. It is very tenacious - even after using chemistry, it often survives and continues to spread throughout the garden.
Horseradish is frost-hardy, shade-tolerant, unpretentious to soils - grows on almost any. But there are methods that allow you to get rid of a vegetable that has turned into a malicious weed forever.
Step-by-step instructions on how to get rid of a plant
How to fight by digging?
Digging is effective only in the first two years after horseradish planting. If you dig up the rhizomes at this time - digging the soil around at least two meters and a meter deep - you can get rid of the vegetable forever.
If horseradish grows in one place for more than two years, its roots become thin, very branched, go deep into the ground to a great depth and are very difficult to remove. Digging becomes too laborious and ineffective in weed control.
Important! Do not dig up the root and chop it into small pieces with a shovel. Horseradish is like a hydra: a new bush will grow from each small root. The roots released during digging must be dried and burned, if they are not planned to be eaten.
Blackout is considered by most gardeners to be the most effective method of fighting horseradish. The procedure is carried out in early spring, when the first shoots begin to appear. This way to remove horseradish is very simple - the place of growth of the vegetable must be closed with any dense darkening material. Will fit:
- slate sheet;
- dark opaque film;
- a piece of roofing material;
- a sheet of plywood or metal.
Like any plant, horseradish dies without light... For prevention, it is recommended to leave the darkening material for at least two years to avoid regrowth from the remaining roots.
What to use from herbicides and how exactly?
If the darkening does not help or you need to remove the weed already in the current season, you can use herbicides.
The most effective:
- Tornado - the agent that is applied to the leaves of the plant, it penetrates through the stem to the root system, destroying horseradish very effectively. Spray greens very carefully, in dry, calm weather, so as not to damage the surrounding crops.
- Roundup, unlike other herbicides - effective, but quite safe for the surrounding plants. Roundup destroys the top of the vegetable without affecting the root. Immediately after its application, it is necessary to plant other cultivated plants next to the etched horseradish.
You can use ammonium nitrate to control weeds.
For maximum effect it is necessary:
- Cut the leaves as low as possible to the ground, expose the roots and stick small plastic tubes into them.
- Ammonium nitrate is poured into the tubes.
The chemical enters the root system and destroys it. The procedure must be repeated at least twice a season, and in the fall the site must be dug deeply, choosing the roots.
You can also use ordinary store-bought fertilizer nitrate. It is necessary to bring it under the horseradish root several times throughout the season, until the very frost. Saltpeter will constantly stimulate the growth of the plant, preventing it from preparing for wintering, and the root will freeze out.
Depletion of the root system
If you have time and patience - you can get rid of horseradish in several seasons by depleting its root system... For this:
- the bush is cut off several times per season;
- the roots are dug around and chosen as deep as possible;
- a perennial is sown in place of the bush - for example, clover.
So the horseradish root system will gradually deplete and the plant will die.
How to remove quickly and permanently?
If you need to get rid of horseradish as quickly as possible, you need to use an integrated approach.
- Cut the plant at the root, use a syringe to inject a herbicide into the roots - for example, "Tornado".
- After the complete death of the plant, carefully dig up the soil, choosing even the smallest roots, and plant a clover or any other densely growing perennial in place of the dead horseradish.
With this approach, even accidentally surviving roots, without receiving light, will gradually die.
So that horseradish does not grow throughout the garden, its root system must be limited in advance to a small space. To do this, the vegetable is planted in:
- metal buckets;
- dense boxes;
- old barrels.
Reference! The metal is impervious to roots, and there will be no problems with overgrowth.
Thus, in order to get rid of horseradish, or rather its distribution over the land, it is necessary to act in an integrated manner. That is, you need to simultaneously use several methods of struggle. In the fall, it may seem that they managed to get rid of horseradish, but even the tiny surviving roots are capable of sprouting abundantly in the spring. You have to start all over again. Therefore, in order not to complicate your life, it is necessary to prevent the growth of horseradish even at the planting stage.
