10 Best Weed Killer Reviews For 2019

You might already know it, but a great-looking lawn is not just the result of home-owner vanity. It actually has functional and economic value. In terms of function, the lawn helps lower the ambient temperature of the property. This results in lower electricity usage in hot summers. Additionally, a healthy lawn contributes to the stability of the property, protecting it against eroding. In terms of property value, lawns increase curb appeal, helping toward faster sales. Finally, in terms of emotional well-being, a healthy, green lawn is known to help reduce stress.

That said, weeds exist.

The sole purpose of weeds is the same as any other thing: to proliferate. This goal is something weeds are very good at achieving. Within any season, a healthy lawn can be overrun by weeds. If the weeds are not removed, they can result in a patchy lawn that looks horrible. However, if they are allowed to take over, they will out-compete the lawn for nourishment, resulting in increased expenses and efforts to repair. However, when it is time to get rid of weeds, buying the best weed killer can be one of the most complicated requirements known to lawn-loving humankind.

Categories of weed killer

When it comes to types, there are two general types of weed killer. The first is contact, which kills weeds on contact. The second is systemic, which penetrates the weeds, typically through the root system, and kills the weeds from within.

Chemical versus all-natural

Within these two broad categories of weed killers, there are two additional categories: chemical and all-natural. Both are intended to contain substances harmful to weeds and less harmful to people, animals, and lawn.

In terms of weed killers, many chemical-based, however, are made of so many different chemicals, you must know your main ingredient to make an informed choice. The main ingredients are the chemicals known to kill weeds.

All natural weed killers create an environment hostile to weeds. For instance, increasing the salt or ammonia levels in the lawn can kill weeds and leave the lawn standing.

Application

For smaller areas, weed killers can be manually sprayed via a spray bottle. However, for larger areas, it is best to find a weed killer that comes in a hose-connector-equipped bottle. These types of bottles allow you to hook up a hose channel water through the bottle where it mixes with weed killer. This mixture then sprays out of the bottle. Powered by the force of your water hose, these bottles can fan weed killer out over a large area.

IMPORTANT: commercial tips for the average home user

You might wonder why landscapers are able to apply weed killer via one of those commercial-grade metal canisters to achieve lush, green lawns. The secret is not what is in the canister. Instead, the secret is the mix.

Weed killer is regulated. Commercial landscapers do not use stronger poison. That is illegal. Commercial landscapers use a cocktail, consisting of two or more readily available weed killers. Combined, this cocktail of mixed, active ingredients obliterates all the weeds in one pass.

The key, of course, is to purchase two types of weed killer, each with a different active ingredient. Unless you have a container that you can mix them in, you will have to apply the weed killer in two passes. This extra effort notwithstanding, the result is a lawn you can enjoy for the rest of the season.
