Crabgrass Prevention & Control

Crabgrass, sometimes confused with quack grass, is an undesirable, troublesome weed grass with a coarse texture and ugly, light green color. It can turn a homeowner’s thick, lush, green lawn into a thin, weak, patchy one if left untreated.

Is your lawn protected from a potential crabgrass invasion? Read on below for crabgrass identification and control tips.

Crabgrass Identification

Fast-moving crabgrass infests lawns across the country. Since there are many different weed grasses, it is critical that the undesirable grass be correctly identified. For example, if you see a coarse, ugly grass infesting your lawn as soon as the snow melts in early spring, it is not crabgrass.

Early and correct identification is important since the quicker you take action against crabgrass, the sooner you will be see favorable results and the greater your chances of preventing its spread. Your local Weed Man professional can help you properly identify what weed grass your lawn has and recommend a treatment and maintenance program.

Crabgrass Facts

The following are several facts homeowners should know about crabgrass, the conditions that cause it, and what can be done to help stem the tide if a crabgrass infestation occurs. It should be noted that control measures for annual and perennial weed grasses differ, and controlling crabgrass can take several seasons of work.
 
  • Crabgrass is an annual weed that is very difficult to identify early in spring since only plant skeletons are present at this time.
  • Crabgrass favors sandy, sunny locations in a weakened condition. Areas damaged by insects or along sidewalks and driveways are prime targets for crabgrass attack.
  • Crabgrass cannot be controlled with broadleaf weed control products.
  • Pre-emergent control applications are the most effective way to keep crabgrass from sprouting.
  • A strong, healthy, properly fertilized, mowed and watered lawn provides the best defense against crabgrass. Thick, lush, insect and weed-free lawns allow few open sites for crabgrass to establish.
Preventing & Controlling Crabgrass
 
  1. Use Pre-Emergent Control. Because germination occurs when soil temperatures reach about 55 degrees Fahrenheit, an application of crabgrass control material in the fall or very early spring before crabgrass seeds have had the chance to germinate is important. Weed Man’s pre-emergent control product forms a barrier to stop crabgrass seed roots from germinating. Keep in mind that this barrier must not be broken by raking or digging.                                                                
  2. Feed Your Lawn. Fertilizer will provide your lawn with the nutrients it needs to remain thick and healthy throughout the growing season. Regular applications will ensure a denser turf structure that can help keep undesirable growth at bay.                                                                                  
  3. Maintain the Health of Your Lawn. Ongoing proper maintenance is also an important step to help rid your lawn of crabgrass. One of the easiest maintenance steps is to remember not to mow your lawn too low. Taller grass will shade the soil and make it less hospitable for many weed seeds, like crabgrass, to develop. Most grasses do well at a mowing height of 2 inches to 3 inches, and some varieties even higher.                                                                                                                                     
The fight against crabgrass requires patience and a commitment to creating and maintaining a healthy lawn. It will take some hard work but a thick, dark green, crabgrass-free lawn is well worth the patience and special care.
