Do you really want to wait for the weekend so as to search for the labor who could pick the weed and uproot them with manual effort for which you would be paying huge amount of money as labor cost to them or else think about buying the best weed killer that would be most effective in its operation and would make the plants dry in just two hours. This type of weed is typically called as the contact weed killer and there are also killers of type systemic which would follow a process to kill the weeds in the natural process of reducing the chlorophyll that is very much required for any plant to grow in green color and survive for a very long time.
Though weeds do not produce any food for us to consume, still they need to produce food for their survival which is possible only with the chlorophyll that is present in it. Hence, it is required that you buy the systemic weed killer for lawns so that they do not spoil rest other plants or else the delicate grass which you have grown with lot of effort. You might have also hired the experts to help grow the grass evenly in the lawn. If you give up maintaining the lawn then it would eventually cost you the same amount of money that it costed for the first time set up as weeds would totally occupy the lawn area and would kill the grass and take over its place thus making the premises quite odd.
Since it is a known fact that growing the lawn grass from the beginning would be too costly, you should immediately react and buy the weed killer, apply it to the lawn and make it look green and attractive for the viewers visiting your premises.
