Recently, there have been huge thickets of hogweed. This plant carries danger not just as a weed grass, but also as a poisonous crop. Therefore, we get rid of the hogweed on the site as soon as we notice its appearance.
To successfully combat weed, it is necessary to study its characteristics well. This will help create unbearable conditions for the development of the hogweed, and he will leave the favorite site.
The plant prefers dry soil with a good drainage layer. In a marshland, it does not grow. Hogweed will not develop in the lowlands, where moisture often stagnates after heavy rainfall.
Needs a weed in good lighting. It does not grow in shade and partial shade. The roots near the grass do not go deep into the soil and reach a maximum of 30 cm.
Hogweed is propagated by seed, not rhizome. In this case, the flower does not need pollination. Even after cutting the plants, the seeds retain their ripening ability. Therefore, if there is a peduncle, it must be packaged in a large plastic bag, then burned.
If the seeds still hit the soil, you should not hope that low temperatures will destroy them in the winter. Frost contributes to the hardening of the seed, and not its destruction.
Germination of seeds persists for about 10 years, so without mulching the soil can not do.
If you simply cut down the stem without digging out the roots, new shoots will appear from the root buds. In the future, the plant will begin to actively develop, crowding out other weeds.
It dies only after flowering and seed maturation is completed, so annual mowing does not bring the desired result.
Phased Weed Disposal
The struggle with the plant is carried out in stages and takes not a single season, since the cow parsnip is quite strong. Protective clothing is used for the duration of the work. Hands, feet, torso, head and face should be carefully covered. This will not allow poisonous juice to fall on a person and subsequently burns will not occur.
If the juice still penetrates the skin, it should immediately be washed off with warm water and soap. If there is no way to immediately wash, you can not allow sunlight to hit these parts of the body. Before water procedures, undressing is recommended in the shade.
Stage 1 consists of the direct destruction of the weed. The stem must be chopped with an ax and chopped. Then burn it. The remains of the cow parsnip should not be left on the site or sent to the compost pit, otherwise you can never get rid of it.
If you carry out the manipulation in the last decade of May or in early June, when the stem did not have time to lignify, even a well-ground shovel will help to cope with the plant.
You need to chop the stem below the basal neck. In this case, the weed will not release lateral shoots.
Now you need to do the rhizome. The root system is dug at a depth of 30-40 cm around the entire perimeter of the crown of the weed. Then everything is chopped and burned.
After you need to do the soil. It is covered with a thick layer of mulch. Even if hogweed seeds remain in the soil, the shelter will not allow them to germinate. As mulch, it is not recommended to use sawdust, hay, straw or compost, because the seeds retain their germination for a long time. As a covering material, it is best to use a dense black plastic film.
After rolling over the topsoil, the mulch is pressed with old boards or bricks to eliminate the gap. If you leave a gap between the film and the ground, then the cow parsnip will sprout again and damage the covering material.
The very next year after mulching, an empty area can be sown with lawn grass.
If there is a large amount of lignified hogweed on the plot, you need to purchase “Roundup” in the agricultural store, and a large syringe at the pharmacy. Then put on a protective suit and give each plant an injection. Subsequently, all weeds will die along with the root.
