Lawn Weed Control

Posted on: August 20, 2011

A little lawn weed control as summer nears will provide you, your family, and friends a beautiful place for a party or any type of gathering. Having a little weed control you will be able to relax knowing you have a place for everyone to have a good time.

Knotweed, path rush, and goosegrass are some weeds that are caused by the soil compacting. If your soil has poor drainage it can bring an invasion of sedges, rushes, or Virginia buttonweed. The roots of turf grass need plenty of oxygen and if the soil is saturated with water oxygen has no way of getting through. If your soil has a low level of nitrogen, white clover can appear. You will need to correct these problems before you start using an herbicide. The first thing we should do is test the soil pH level. In order to grow a decent lawn the level should read between 6.5 and 7.0.  If your soil has too much acid sprinkle on some lime to bring the acid level down; if it does not have enough acid add sulfur to raise the level. A lawn will grow very well in a loamy soil with silt, clay, and sand mixed in. Too much clay will cause soil compaction.


The more natural lawn care that you give to your yard the better the lawn will be. Grasses are classified as to the type of shade they need, their climate, wear and tear ability and the quantities of nutrients and water they need. Your local garden nursery or home and garden center should be able to tell you which grasses will work well in your area and which ones work best for how you want to use it,  

Mowing your lawn often is not only good for your lawn but is also a method of weed control. In order for the grass to remain healthy the length should be between 2 1/2 and 3 1/2 inches tall. If you mow it shorter than that you could expose the surface roots, the aeration of the surface will be lowered and the soil dries out quicker.    

Watering thoroughly will motivate the lawn to expand to a deeper root system which creates better drought resistance and it becomes hardier. If you water more often and lighter the roots will remain very shallow and you will end up with more weeds. Early morning is the best time for watering the lawn; evaporation becomes much slower and the foliage will have the entire day to dry.

The bare areas of the lawn should be patched up as soon as you see them; this prevents an invasion of weeds. Bermuda grass or St. Augustine grass fills the areas quite well. If you decide to re-seed the areas you need to hand pick the weeds when they appear.  

Weed control without the use of chemicals is the better way to get rid of weeds in the lawn or garden. A natural weed killer of ordinary household vinegar is not recommended for your lawn because the acetic acid in it will harm the lawn. Vinegar as an herbicide is best used in a planting bed of young weeds when you can aim the spray right onto the weeds.
