The truth is that few lawns are naturally perfect. While roughly five percent of lawns in the world might have lush grass and perfected conditioners which will prevent the growth of weeds the other ninety-five percent will not. In stances where a given individual’s lawn is not perfect by default a weed killing agent may be desired. The question is, “Which one?”
Weed killer comes in many forms. These forms also have two base types. The base types are spray and granular. The forms are non-selective, sege or grass-nut, grassy weed, and broad leaf weed killers. On a related note, some people enjoy Bermuda grass as a lawn type. However, other individuals will see it as a weed when it creeps into their rye, fescue, or bluegrass oriented lawn. Most weed killer types will not actively work on it without killing the rest of the grass as well.
The appropriate type of weed killer for lawns will be determined by the nature of the grass and the weeds involved. Individuals that do not wish to kill their grass while removing weeds will either need to pull them up by hand, or kill off the bread leaf weeds with the appropriate killing agent. Grassy weed killers and non-selective types will kill grass. Round-up is considered one of the best weed killers on the market but it can kill grass, for instance.
The best method is to use a preventative spray before weed season truly begins. This will kill off the weeds before they ever have a chance to grow.
Beyond choosing the appropriate poison there are a few tips for proper usage. Grass is one of the most resilient plants in the world. Very few other forms of plant life can handle the stress of being walked on, cut, ripped, and etc. However, certain actions can be deadly to it, even if it is resistant to the poison being used.
The most important tips are:
1. Do not spray in very hot weather. Any temperature above eighty degrees Fahrenheit is too hot. It will possibly overstress and kill the grass.
2. Do not apply chemicals around young grass. Just as a human infant cannot handle the rigors of an adult, neither can baby grass. Give new grass at least four or five months to build up its strength. If not, the chemicals will be likely to burn and kill it.
3. Do not apply weed killer after mowing the grass. The grass itself should be fine if you do. However, the poison must be absorbed through the leaves of the weed. If the leaves are cut off then little of the poison will get into its system. It is simply wasted effort to spray after cutting.
