Maintaining a lawn might seem like a difficult task, especially when weeds sprout up and become a pesky problem. Weeds can be very difficult to get rid of because they need to be killed at the root and are easily propagated. While there are several ways you can kill weeds, a common and simple way to kill weeds is to use a weed killer spray. Today, we offer you a few options and reviews for the best weed killer spray on the market.
Weeds can wreak havoc on your manicured yard or lawn, as they are very difficult to get rid of once they have sprouted. They also spread very easily as their seeds are easily propagated, which can be a nightmare for any homeowner. Once weeds have emerged from the soil, they need to be killed at the root. While there are several ways to kill weeds, you should determine the type of weed you have and what kind of weed control you need to rid your lawn of unwanted weeds.
Weeds come in many different types, but all types can be very difficult to control. Dandelions and clovers are two very common types of weed and are classified as broadleaf weeds. A broadleaf weed is a perennial weed that typically emerges in early fall.
All weeds, including broadleaf weeds, can be killed and controlled in several ways including pulling weeds by the root, using an herbicide, or by using an organic weed killer, such as vinegar. Since pulling weeds is often very tedious and time consuming, a lot of people consider that using an herbicide or weed killer spray is the easiest method to kill weeds.

A simple way to control weeds is to use an herbicide that is specially formulated to kill specific plant species. However, not all types of weed killer sprays are the same. The two major types of weed killers are classified as either selective or non-selective, and are often sold as a weed killer concentrate. Let's take a look at four popular types of herbicides:
The oldest way to kill weeds is to use an organic weed killer like vinegar. Vinegar contains acetic acid, which acts as a natural herbicide and will kill weeds without using chemical additives, which is better for the environment and everyone's health.
Normally, the higher percentage of acetic acid means a stronger weed killer, meaning you can boil down the vinegar to yield a stronger weed killer, then simply spray it on the weeds leaves. This is also an easy solution since most people already have vinegar in their kitchen.

These are formulated to only kill certain types of weeds such as broadleaf weeds. These types of herbicides are a perfect solution if you are trying to figure out how to kill weeds but not grass and other vegetation, as selective weed killers only target specific types of weeds.
A major caveat of these types of herbicides is that they sometime kill certain types of grass such as St. Augustine grass, so it is important to always do a test patch on your lawn to determine if your selective weed killer is also a weed killer safe for grass.
Non-selective herbicides will kill everything that they come into contact with, so they are not suitable for lawns as they are both a weed and grass killer. However, determining what is the best type of weed killer is based on your yard’s need. Non-selective herbicides are also grass killer herbicides, so extra precautions should be taken if you want to preserve your grass.
Selective, non-selective and organic liquid weed killers all kill weeds by similar mechanisms as the herbicide is absorbed through the leaves. Dry weed control agents come in granules that contain weed control chemicals. Post-emergence granules are also absorbed through leaves and then travel down to the roots, where they kill the plant.
Most weed control granules are post-emergent weed killers, meaning they kill weeds after they sprout out of the soil. In order for granules to effectively eliminate weeds, one must first water the lawn, so as to allow the product to dissolve on the unwanted plants.
If you’re wondering the best time to apply weed control to your lawn, it is dependent on the type of weed killer. Pre-emergent weed killers are typically applied to lawn before watering, allowing the weed killers to travel down to the soil and prevent weeds from growing whereas post-emergent killers are usually applied after watering your lawn.
Another way to kill weeds is using weed killer granules, which are sold as a dry granule and are typically the best weed killer for grass. An alternative to liquid weed killers for lawns, these dry granules are typically applied to wet lawns as they then make their way down to the roots where the herbicide then kills the root. Glyphosate is a common active ingredient in many weed killers, especially in weed killer granules.
Overall, there are several types of weed killers. Choosing the best weed killer will depend on your type of weed and also your lawn’s needs. You should choose the weed killer that can best meet these needs.
