Factors to Consider When Getting the Best Weed Killers

1. Location of Weeds

The location of the weeds plays an important role when you are choosing which weed killers to go for. For example, non-selective weed killers often target any plant that they land on. Therefore, these non-selective weed killers are great for dealing with weeds that are along your fences, in sidewalks and driveway cracks, and around raised bushes.

If you can exercise extreme caution while applying the treatment, you could also use the non-selective weed killer on weeds that are in between your crops or grass. Nonetheless, all the options above are safe to use on grass. Therefore, you don't have to worry about wiping out your lawn.

On the other hand, selective weed killers are designed to target weeds. Therefore, you don't have to be extremely careful when dealing with these types of weed killers. However, non-selective weed killers are more effective than their selective counterparts.

2. Stage of Growth

Before you settle on one of our best weed killers that won't kill your grass, we suggest that you take some time to analyze the stage that your weeds are at. This will allow you to select the most effective post-emergent weed killer or pre-emergent weed killer.

Some weed killers are designed to attack the weeds in the seedline stage, while others can only kill the weeds once they have sprouted their first leaves. Therefore, knowing which stage your weeds are at will allow you to achieve the best results when carrying out your lawn care.

Another thing to ensure when you want to control weeds is that the model you choose has the right chemical composition to deal with the stage at which your weeds are.

3. Reaction Time

As we've seen above, different weed killers take different times to work on the weeds. Therefore, take into account the time you'll need to wait before you see your desired results. If you want immediate results, choose our second or third picks above.

These options that work almost immediately often offer a contact burn that gets the weeds right away. They work with sunlight to burn the plant tissue of the targeted weeds.

If you aren't in a rush to kills the weeds, you can choose a systemic weed killer that works by gradually releasing chemical agents. This best weed killer that won't kill grass works great in warm and cold weather, making it perfect for year-round use.

4. Types of Weed Killers

You can either choose liquid weed killers or granular weed killers.

a). Liquid weed killers

These are the most common and give you more flexibility when applying them. You can either get a weedkiller concentrate or spot spray weedkillers. The concentrate requires you to add a few gallons of water to dilute it.

You can then apply it using a knapsack sprayer or a watering can. Some require you to add a gallon of water and some a bit more or less. If you want to treat your entire lawn, getting this type will be best for visible results. These weed killers are also great for use in the spring or autumn seasons and if you have a few weeds on your lawn. You can only apply this weed preventer or killer once a year.

The spot spray weed killers don't require any mixing. You purchase the ready-to-use spray bottle and get to work immediately. This type is great for targeting individual weeds. If you have one or two on your lawns, use this type.

b). Granular Weed Killers

These are not as common as the liquid types. Our first pick is a great example of a granular best option that won't kill grass. These options come ready to use and are safe to use on your lawn. They are also rarely used as a stand-alone option.

If you don't have that many weeds in your lawn and prefer to use feed and weed products, this type is perfect for you. However, if your beautiful lawn is infested with many weeds, this type might not be of great use to you. It would be better to use the weed killer concentrate.
