Video: Weed Control
Weeds on lawns are divided into two groups: weeds proper (annual and perennial dicotyledonous plants) and unwanted grains. When dealing with them, one should remember the main rule: the more friendly and numerous the family of "hosts", the more uncomfortable uninvited guests feel. Therefore, the first thing to do is to focus on creating dense grass. Regular balanced nutrition, frequent mowing if necessary, even 2-3 times a week). It is very important to keep the cutting height (at least 4 cm) and not to remove more than 30% of the total plant height at a time. Annual weeds disappear after a couple of months.
Of the perennials, plantain, dandelion, highlander, creeping buttercup, clover and some others remain. When the lawn grass is closed and is able to compete with weeds, chemical control agents can be used - selective herbicides that destroy dicotyledonous weeds, but are harmless to monocotyledonous plants. In no case should you stop intensive lawn care. The space freed from enemies must be quickly reclaimed by the lawn.
So called unwanted herbs can create a big problem. These "relatives" can settle on the lawn for a long time. Outwardly, they look like the owners and even at first do not spoil the general appearance too much, but their aggressive nature can lead to serious consequences. Plants such as bent grass and annual bluegrass (can behave like a perennial) are able to displace everything else that was on the lawn in a couple of seasons. The worst thing is that having driven out the "owners", they start to get sick themselves and die in whole clumps. Fighting such "impostors" is difficult.
The main thing is to strictly follow the care technology in accordance with the requirements of lawn grasses.Lawn varieties of perennial meadow bluegrass, in optimal conditions for them, displace other grasses due to dense tillering, resistance to diseases and the ability to recover at any age. However, in some cases, it takes years for lawn grasses to win a complete and convincing victory. More often than not, you have to put up with the presence of a small amount of wild grasses even on an ideal lawn.
