  • Getting Rid of Crabgrass in Your Los Angeles Lawn

    Getting Rid of Crabgrass in Your Los Angeles LawnCrabgrass is a coarse, low-growing weed that is prevalent in many regions of North America. Here in Southern California, smooth crabgrass is the most common variety. Crabgrass thrives in adverse conditions, particularly intense heat and drought. If left unchecked the plant can spread quickly, leaving unsightly patches of weeds growing in your lawn.

    Because crabgrass grows fastest in unfavorable conditions, the best defense against the weed is a strong, vigorous lawn. By promoting healthy grass growth, you can give your lawn a leg-up on crabgrass and eliminate this troublesome weed.

    Mow Higher

    You can start by raising your mower deck so that the grass in your lawn is able to grow to about 3-4 inches high. This will allow your lawn’s roots to grow deeper and starve budding crabgrass plants of the sunlight they need to grow.

    Water Wisely

    Once again, the goal here is to promote healthy grass growth to combat the spread of crabgrass. To achieve this goal, apply about ½ an inch of water to your lawn twice a week in the cool early morning hours. Watering deeply and infrequently allows water to penetrate the soil more thoroughly, giving your lawn’s root systems the extra boost they need to combat weed invasions.

    Apply Pre-Emergent Herbicide

    If crabgrass has already taken hold in your lawn, you can apply a pre-emergent herbicide in the spring to eliminate it before it spreads in the summer. Just be careful not to apply herbicide to fresh sod, as this can do more harm than good.

  • Employing Pre-Emergent Herbicides

    A pre-emergent is an herbicide that works to eliminate weeds before they emerge into your lawn. When a pre-emergent is used correctly, they will get rid of weeds before you even see them pop up through your grass. It is important to remember that you cannot simply rely on only a pre-emergent to control any weed problems you may have. Maintaining your lawn will not only help a pre-emergent to work better, but you will also have to use less of it. Establishing a healthy lawn from the start is the first step. Before laying your sod, be sure to eliminate any weeds that are in your soil. Starting with a clean lawn will help minimize any weed problems you may have down the road. Additionally, you will want to keep up on all other lawn care maintenance practices like fertilizing, watering, and keeping your grass at a proper height. All these practices create a strong and healthy turf that is able to combat the weeds that attempt to become established.

    Timing is important when applying your pre-emergent. It needs to be applied just before the seeds of the weed germinate, which is usually in the spring time, but the soil can't be too cold. It is best to test the soil temperature, keeping in mind that most weed seeds don't germinate until the soil temperature is close to 50 degrees. It is important to get your pre-emergent down at the right time, before the seed germinates, because of how the pre-emergent works. It works by forming a carpet like barrier under the soil that the weed is unable to penetrate once it has germinated. While it is important to apply pre-emergent before the seed germinates, you actually want the seed to germinate so that it can be exposed to the herbicide and be killed. If it does not germinate it will wait for another chance to germinate when your pre-emergent has worn off. After you apply your pre-emergent, applying the right amount of moisture is crucial. Water is needed to activate the herbicide, but too much water will water down the pre-emergent and it will lose its activity.

    When using a pre-emergent year after year, it is important to remember that using one type will not kill all of your weeds. There is not one specific herbicide that will destroy every type of weed and the labels on your pre-emergent will list the weeds it kills. If you have spent several years using the same pre-emergent, you will most likely have a weed or two that continue to return because your specific herbicide does not contain the chemical needed to kill it. You may want to use a few different pre-emergents in order to solve this problem, but using them at the same time may be too much for your lawn to handle. Additionally, weeds can easily develop a resistance to herbicides, so the same herbicide year after year may eventually prove to be ineffective. To solve these problems, you want to first continue to maintain your healthy lawn (mowing at a proper height, fertilizing, irrigating, etc.), along with changing up the type of herbicide you use. Changing the types of herbicide you use so that you are using different chemicals to combat different weeds is important. Different pre-emergents also work to kill weeds in different ways, such as by interfering with the metabolism of the weed's cells or inhibiting a weed's growth by blocking the division of the weed's cells. So you not only want to pick a new pre-emergent with a different chemical makeup, but you also want to choose one that has a different "mode of action", or way in which the chemical actually kills the weeds.

    Starting with a clean and prepared ground, combined with proper maintenance of your grass and applying the right type of pre-emergent, you will be left with a strong and healthy weed free lawn.
