There are several spreaders in the market that you can choose for your lawn. But you need one that will cover the entire lawn.

What to look for in a good crabgrass killer
Method of application
Crabgrass killing herbicides come in two primary forms. They could be granular or liquid. When choosing your herbicide, you need to think about the best form and method for application which depends on the size of your lawn. For instance, get the herbicide in the form of granules if you have a lawn spreader for a more effective and time-conscious application.
On the other hand, liquid herbicides work well when broadcasting a large garden or lawn using a horse spray. For a smaller area, you can use a tank sprayer instead. Liquid herbicides are sometimes sold as concentrates with instructions on diluting before use, or the herbicide will be ready to use.
The ingredients of your crabgrass killer make it work uniquely. You need to read the label carefully before using one herbicide over the other. For instance, selective herbicides contain ingredients that target a specific plant, such as crabgrass. Therefore, it is safe to spray it even if it gets to contact with the grass on your lawn.
But, you might opt for the non-selective herbicide that eliminates all plants. It is a good choice if you want to start over and do not mind losing your good grass. Therefore, the choice of a crab killer is heavily determined by the type of crabgrass killer, which also depends on the ingredients.
Period of application
You can use a crabgrass killer before the crabgrass sprouts for best results. However, if you forget to do this, you can still use it after the weed emerges. The decision to use pre-emergent or post-emergent herbicide lies in the application period.
Since the weed grows best during warm weather, use an herbicide before spring. But, if you want to spray the plant itself, you need a post-emergent killer that you should use after the weed sprouts during winter.
Aside from killing crabgrass, you should pick a crabgrass killer who goes the extra mile instead of killing crabgrass. For instance, it can also eliminate other weeds from your lawn. The more weeds it kills, the more valuable your crabgrass killer will be. It will also save money since you will not need to buy other herbicides for other weeds.
Similarly, some crabgrass killers are harmless to your grass and other plants. For more benefit, you should pick one that doubles up as fertilizer to rejuvenate the plants you want to grow, even as it kills the harmful ones.
No product is worth buying if it is too expensive. While high prices often mean better quality, this is not always the case. You should aim at getting an effective crabgrass killer at an affordable price. The best way to measure the value of a crabgrass killer is to compare it to the benefits expected. The best-priced one is the one that gives more service than what it costs.
Is it better to uproot or to spray crabgrass?
You can get rid of crabgrass by uprooting or spraying it with a herbicide. However, uprooting is exhausting if you have a large garden or lawn. Besides, there is the risk of pulling your grass along the crabgrass. You also need to be careful when uprooting the crabgrass not to leave seeds behind.
Will rainwater wash away pre-emergent herbicides?
You do not have to worry about the rain after spraying a pre-emergent herbicide. Even though rain will wash the herbicide off the plant, it will slip into the soil, and this is good as it will be more effective. Also, do not uproot crabgrass post spraying, as this will reduce the effectiveness of the herbicide.
Can crabgrass die naturally on its own?
Crabgrass is a seasonal plant. It only grows once a year, during spring, then dies after seeding or when it gets colder. While this means they die naturally, not treating the lawn will lead to more crabgrass growth the following year and the year after since the seeds left behind will sprout in a warm climate.
The disappointment that comes with the emergence of crabgrass on your lawn is troubling enough for one person. However, it gets a little more heartbreaking to learn that there are many crabgrasses killer options to choose from, and you need to do your research before finding the best one for you. Besides, it will add to your lawn expenses. If you feel like this might be overwhelming, do not despair. The benefits from the result will outweigh all the trouble. It will eventually be worth it! I hope this list makes the whole crabgrass killer hunting easier as it will help point you in the right direction. I also hope it comes in handy and that you put the trouble that this weed causes every year as a thing of the past.
