Every gardener comes across difficulties such as removing weeds from their garden. Whether you fight weeds or allow them to visit your garden from time to time, weeds will definitely grow somewhere in the garden.
Where do weed seeds come from?
Some are spread by the wind, some are brought by birds, and others stay in the soil for a few years. While digging the garden soil over, the weed seeds are brought to the surface and begin to sprout. This is why fighting weeds is urgent.
Presence of weeds in the garden soil results in additional financial expenses, which can be avoided.
1. The consumption of natural moisture in the soil is lowered. A garden’s cultivated crops experience this lack and require additional watering.
2. Depletion of soil fertility occurs. Cultivated crops suffer from lack of nutrition. Additional fertilizer is needed.
3. Many weeds excrete harmful substances into the soil, and grow intensively which chokes up the cultivated crops.
4. Some pests and diseases appear on the weeds and are thentransmitted to the cultivated plants.
What’s the difference between weeds and cultivated plants?
1. High seed productivity.
2. Prolonged preservation in the soil.
3. Besides spreading with seeds, it can propagate with rhizomes.
4. It can spread in a vegetative way.
All this can be prevented if you destroy weeds systematically. There are weeds which grow and propagate actively during the cool season and there are others which activate themselves in summer. Many weeds in the north sprout in the spring but can grow well in the south during winter time.
Weed - quack grass. This is crabgrass that is hard to eradicate, which suppresses other plants with its secretions.
What should you know about quack grass
The weeds prefer light, moistened soils, rich in humus.
Crabgrass spreads out fast through them. The rainy autumn period and wet spring contribute to its development. In the summer, when the heat comes and there’s lack of precipitation, quack grass dies and waits for favorable conditions.
Rhizomes of quack grass go 1 2.5"(2-6сm) deep into the soil. With the soil compression, productivity of the crabgrass lessens and its rhizomes suffocate. If the soil remains compressed permanently, quack grass disappears gradually.
How to fight quack grass
1. In places with considerable conglomeration of quack grass, and especially if the the area affected is vast, you can use rye crops to combat it. If you sow the rye within 2 years, the soil will completely cleanse itself of the quack grass. Certainly, if there’s quack grass on the lawn, the lawn’s owner will not grow rye to combat quack grass.
2. If there are blank spots on the lawn, they are a favored place by weeds. That’s why when sowing the grass for the lawn, it’s important to stick to the planting density, and use only sowing material of high quality, free from weed admixture. You need to systematically combat quack grass.
3. There’s a method to combating quack grass in the lawn. Quack grass doesn’t tolerate systematic short mowing. Its rhizomes wear out and it disappears from the lawn little by little. But this fighting method requires systematic regularity. If crabgrass has grown 2 2.4"(5-6сm), you need to mow the lawn right away. Usually, the grass is mowed weekly.
4. An ecological method of combating crabgrass is by planting the plants that suppress quack grass. If crabgrass is found in the garden or flower-bed or in a group of perennials, it can be eradicated by planting dahlias. They are ornamental perennials with large flowers and thickened roots of a tuber kind. However, this method doesn’t always prove to besuccessful for the given weed.
5. In the spring, when young growth appears, it is actually the weed’s growth since it is more winter-resistant and starts its growth faster than cultivated plants. At this point, the quack grass grown from the seeds can be removed easily because its rhizome will only develop in 2-3 months. With the rhizome, it’s much harder to pull it out.
6. There are chemical ways of combating quack grass. For this purpose, various herbicides are applied, which can either affect a certain weed kind, and there are indiscriminate herbicides.
Herbicides with a base of glyphosate may be used. Glyphosate is a substance produced on the basis of glycerin amino acids, affecting chemical reactions in the weed. When the herbicide gets on the weed, the weed dies. You can apply Rang-Up, Raunder Pro with 41% Glyphosate, Finale on the basis of Glufosinate. Finale is used as a contact herbicide. It affects only above-the-ground part of the quack grass, without touching its roots.
Herbicides should be used during the period of active growth of crabgrass. Taking into account the fact that these are not selective herbicides, you need to use them very carefully in order to avoid harming the other cultivated plants. By systematically combating weeds, you can get rid of quack grass.
