10 Best Crabgrass Killer For Won’t Kill Grass [Reviews in 2022]

Everyone who owns a lawn knows that generation of crabgrass is one of the most annoying problems and it should be taken care of as soon as possible. Crabgrass is also a type of plant that grows on your lawn. But unlike the plants and grass that you would want in your lawn, crabgrass is actually very bad for the overall health of your lawn. It has multiple stems and leaves, thus the name ‘crabgrass’.

This is a procumbent type of plant and easily grows on any surface whether it is a lawn, driveway, or a simple crack in the sidewalk. If you don’t take care of crabgrass in time, it will soon take over your lawn and remove all nutrients from the soil that are necessary for plants. In order to remove and prevent crabgrass, you will have to invest in a decent crabgrass killer. But before that, make sure you acknowledge some important factors of a crabgrass killer.

  • Shelf Life: When you buy a crabgrass killer, you won’t definitely know exactly how much you will have to use to cover your lawn. In most cases, there will be a significant amount of solution left in the container. If you don’t want to invest in yet another container after a year, you should prefer the one that has a long shelf life. This way, you can keep some spare crabgrass killer in your house and use it in the future if required.
  • Quantity: Crabgrass killers are available in both, small containers, as well as, large packages. The difference in quantity is provided so that you can select the one that is perfect for your lawn size. If you buy a smaller canister of the crabgrass killer which does not cover your lawn completely, the procedure will be ineffective since it won’t remove the crabgrass completely from your lawn.
  • Effectiveness of the Compound: Crabgrass killers are basically chemical compounds designed to target and destroy crabgrass and other similar anomalies that usually appear in a lawn. But before you buy a crabgrass killer, you need to make sure what other elements it can remove from your lawn. For that, you can simply check the active ingredient in the compound.

2. Application Method

Herbicides are definitely one of the best compounds you can use to take care of your lawn.

3. Shelf Life

The shelf life is yet another important factor when it comes to chemical and essential compounds, especially in the case of gardening related peripherals.

A lot of manufacturers also mention the approximate coverage area along with the product that gives you a fairly clear idea about the applicability of the product for your lawn. Even if you are buying a larger option just to be on the safe side, just make sure that it has a long shelf life so that you will be able to use it multiple times over the span of a couple of years.
