How to Grow Weed-Free Lawn Grass?
Ways to destroy weeds
The most effective weed control measure in small lawn areas is weeding. The first time this can be done two weeks after sowing the lawn, when the root system of weeds is poorly developed. When weeds of perennials (sow thistle, dandelion, buttercup, plantain), they are pulled out with a rhizome. The roots of perennials sitting deep in the ground are removed from the ground using a special narrow, long shovel. Removing weeds by hand is difficult, but often the most effective. At the end of weed removal, the damaged area is well compacted, if the bald spot in the lawn is large, the seeds of the lawn grass are sown.
Regular mowing of the lawn can also effectively control weeds. Weed grass, which is pruned many times, grows poorly and soon dies, not being able to develop normally.
The use of systemic herbicides and their mechanism of action
Recent advances make it possible to answer the question of how to deal with weeds on the lawn using systemic herbicides. These chemicals eliminate the heavy physical labor of weeding. They, miraculously recognizing weeds and destroying them, do not affect the lawn grass. A herbicide such as Lontrell 300 destroys the green parts and roots of weeds.
The mechanism of action of a particular drug depends on the dose of the active substance and the sensitivity of the treated plants.
Weeds absorb the herbicide through foliage and root systems. It moves through plant cells along with nutrient components, accumulates in young plant tissues. As a result, the aerial part and the root system of the weeds are destroyed two weeks after treatment.
Conditions for successful weed control on the lawn after sowing
The first ingredient for success in lawn weed control is preparing the site for sowing. Small weeds can be destroyed on the lawn without causing much harm, but the abundance of weeds will prevent the lawn from growing.
There are several options for how to clear the area of weeds so that they do not interfere with the shoots of lawn grass:
- dig up the area, select all the roots of the weed, level and tamp with a roller;
- remove the top layer of soil, level the area, put fresh soil with a layer of at least 15 cm;
- treat the area with continuous herbicides, for example, Valsaglif.
After sowing lawn grass, it is necessary to regularly clean the lawn by weeding or applying systemic herbicides. It is possible to apply the herbicide not to the entire lawn, but directly to the weedy perennial, by injecting it into the trunk with a syringe or by treating the plant with a spray bottle.
A very important measure in the destruction of weeds is mowing the lawn grass, which prevents the development of annual weeds, and is useful for the lawn.
Another factor that you need to pay attention to is the cleanliness of the surrounding area. The lawn takes a long time to form, over two or three years. Weed seeds are carried onto the young lawn by the wind.If the site is surrounded by unkempt land with a lot of weeds, it will be difficult to grow a level, clean lawn. In this case, it is advisable to fence off the lawn area to reduce the likelihood of weed seeds entering.
Good luck in growing beautiful lawns!
