Crab grass makes your lawn look ugly and is one of the culprits that steals nutrients that should be for your lawn. Removing crab grass is an easy process if done correctly. But if these are left to its own devices, it can definitely threaten the health and beauty of your lawn.
Other than the usual weed control measures, there are varying methods of controlling crab grass, depending on the scope of its occurrence.
But first, what is Crab grass?
Crab grass is a variety of weed that grows and spreads rapidly throughout the US and some parts of Canada. In a warm season, it can spread over 100,000 seeds.
These weeds take away the nutrients needed by your turf grass and if left untreated, can ruin a lawn or garden resulting in bare patches and dead grass.
What’s the difference between Pre-Emergence and Post-Emergence Herbicides?
Herbicides is an effective method to removing crab grass. It’s purpose is to kill the crab grass without harming the plants on your lawn. Make sure that the herbicide that you will use is specifically formulated to kill crab grass. Using an all purpose herbicide may hurt other plants and your natural turf grass.
Pre-emergence herbicide is applied before the appearance of crab grass in the spring. Post-emergence should be used on already sprouted crab grass. Herbicides in liquid or granulated form are equally effective. Homeowners should refrain from applying pre-emergence herbicides after grass seeding.

Issues with herbicides
Possible side effect with herbicides is that an individual may notice their natural turf grass is turning brown. Cause of this issue is over application of herbicide. This can be fixed by frequent, deep watering of the lawn. This washes away herbicide residuals and cleanses the plant roots. Making sure that the herbicide to be used is specifically intended for crab grass reduces the risk of damaging the turf grass. It is preferred to use eco friendly herbicides for the safety of your family and pets.
Another method for killing crab grass.
If the infestation of crab grass is minimal, you may try to manually pull the existing crab grass and allow the roots to dry out. This will kill the crab grass and prevent it from producing seeds.
