    Buyer’s Guide – Deciding on the Best Crabgrass Killer

    You have read the reviews of the 10 best crabgrass killers and are probably left wondering which one would best suit your needs. In fact, you could quite possibly be thinking that many of them sound good and there isn’t a clear choice.  Well, let’s look a little deeper and see if we can eliminate a few from the list so your choice is more obvious.

    Organic vs. Inorganic

    Who would have guessed that there would be weed killers that are actually organic? The organic weed killers are made from corn gluten, which is nothing more than the residual from making cornstarch. When it is used to control crabgrass, the gluten will keep the seeds from germinating and therefore, rid the lawn overtime of the weed. Sometimes this type of weed killer contains a nitrogen base that will help to keep the lawn green and vibrant.

    Inorganic weed killers are sometimes referred to as herbicides, are chemical-based, and can be very selective as to which weed or weeds it is targeted to kill. They can even be systemic, meaning that they will kill to the root because the chemical has traveled through the entire plant. be sure to read the label on the bottle of your product to make sure that any of the chemicals are not harmful to kids or pets.

    Liquid vs. Granular

    Whether you choose a granular product or a liquid one is also an option for you. The liquid product is applied by using a sprayer of some kind, such as a tank sprayer. You can use the tank sprayer to spot spray specific weeds that you see on your lawn. The garden sprayer is one that is connected to your garden hose and mixes the solution of water and weed killer perfectly. This is a quick and easy way to apply the product.

    Granular products are spread over the lawn with a hand spreader or wheeled spreader. A wheeled spreader has a bowl or tank and you adjust the spreaders opening to the correct setting. As you push the spreader over the lawn, the product is dropped onto the lawn and spread evenly over the lawn. Many of the granular products also have a fertilizer in them to help green up, thicken, and/or strengthen the roots of the grass.

    preparing Spectracide HG-95703 Lawn Weed Killer

    Pre-emergent and Post-emergent

    If you are looking to kill crabgrass before it actually begins taking over your lawn, or if you are looking to treat your lawn at the beginning of the growing season, then you will be using a pre-emergent product. Usually, these are applied in the early spring when temperatures are still mild and the growing season for crabgrass and other weeds is just beginning.

    Using a post-emergent product means that you will be treating your lawn later in the year or the fall season. This is the time when the crabgrass has already taken root and you will be looking to kill more mature plants. The product used during these times of the year should have a systemic property that kills the weeds down to the root.

    Liquid Crabgrass Killer
    • Needs to be mixed or diluted
    • Various spray options
    • Kills on contact
    • Rainproof in less than an hour
    • Last longer
    Granular Crabgrass Killer
    • Need a spreader to cover lawn
    • Can be unsafe for pets
    • Longer rainproofing time
    • Can have fertilizer with it
    • Not cost-effective for large areas
