Our Comprehensive Buying Guide
We know that a beautiful lawn can really make a difference, as it makes the house look beautiful and well maintained, and you can also enjoy some peace of mind and tranquillity by spending time in the garden. However, we also know that keeping everything weeds-free is not an easy task, as these pesky plants seem to be growing pretty much everywhere.
Therefore, you are probably looking for the most effective way to keep them under control. There are several ways to do this, including removing them by hand. However, the most time-efficient alternative is finding the right solution. Depending on the area you need to cover, you might want to look for the best weed killer spray for lawns that is already pre-mixed.
There are the concentrated alternatives as well, some of them specially designed for certain areas, so you are not wrong if you are looking for something in particular, such as the best weed killer for southern lawns. We know that there are plenty of products in this category so, in the next lines, we’re going to take a look at how to choose the right one for your lawn.
Is it necessary to remove weeds?
This is a question that some of you might have, and the answer is “Yes!” if you want to have a well-kept lawn. Weeds are those unwanted plants that always seem to make their way into a garden or lawn, and are very difficult to remove. While it’s true that they are part of the natural habitat, they can pose some problems, so it’s better if they are dealt with right away.
The first thing you want to keep in mind is that weeds need nutrients, light, and water as well in order to thrive. The thing that makes them special is that they are going to do everything they can to get these essential elements, which means that they can end up hurting the lawn. They are aggressive and usually expand faster than other plants.
If they are not kept under control, they can compromise an entire lawn rather quickly, as the grass doesn’t receive the necessary nutrients. Moreover, given that weeds grow very fast, they can actually suffocate the grass and other plants. If this isn’t risky enough, some of them can also be poisonous to other plants.
Another aspect worth considering is that they can also have secretions that can be harmful to crops, flowers, and lawns. So if you’ve invested in high-quality grass, you probably don’t want it to die away in one season.
What you should look for in a lawn killer
Before actually buying a weed killer there are several factors that you need to take into consideration. The product needs to be suitable for your lawn’s needs, as otherwise, it can end up damaging it even more, or not being effective at all. You also need to know what type of weeds you are dealing with to get exactly the product that can get the job done in no time.
The first aspect you should look at is coverage, given that various products can be used in different concentrations. Take a look at the information provided by the manufacturer, as you may have to adapt the water-to-substance ratio depending on the type of weeds you are dealing with as well.
With this being said, think about the surface that you need to cover, and see how much water is necessary to create the right mix. This way, you will ensure that you have enough for the entire lawn. If you simply need to spray a bit around plants, you can always choose a pre-mixed spray that will make the entire process easier.
Selectivity & effects
Of course, you should always choose a selective product, since you are going to spray it over the lawn. This means that only the weeds are going to be affected, while the grass remains unharmed. However, you need to know what type of grass you have on your property, and then check the instructions to make sure that the formula is safe for it.
Furthermore, if you need to deal with perennial weeds, other plants might be impacted as well, so you want to take a look at this aspect as well. In terms of effects, if the herbicide you choose is right for your lawn’s needs, you shouldn’t see any negative impact. However, do keep in mind that any chemical that you use over and over again can eventually decrease the soil’s quality.
For this reason, you can also look for the best organic weed killer for lawns, as these products might be safer in the long run. In the end, it all depends on what you need to keep under control and how often.
Last, but not least, you should also think about the areas that you need to cover, and by this, we mean the type of green space. If it’s around the edges and the weeds have shallow roots you can use one product, while weeds that are at the heart of the patio or lawn are certainly stronger, so you may have to use a more potent weed killer.
Frequently Asked Questions
Q: How do I use a weed killer for lawns?
The answer, in this case, depends on the type of product you want to buy and on the area you need to cover. If we’re talking about small spaces around your home, then you can simply buy a suitable premixed spray and apply the treatment locally.
However, if you need to keep large areas free from weeds, then you should buy a weed killer that can be mixed with water and then applied using a garden hose with a fan nozzle.
Furthermore, you also need to make sure that the substance you are going to apply won’t damage the lawn, as there are some of the options on the market are selective, and also that it’s suitable for the type of weeds you are trying to get rid of. For this reason, if you are not sure what product you should get, you can always contact the manufacturer for further information.
Q: Are all weed killers safe?
No, not all weed killers are safe for any lawn. Some of them contain chemicals that can affect certain types of grass, so it’s very important to carefully read the label before applying the product. Moreover, if you are still not sure whether the product will damage the lawn as well or not, you should look for all the necessary information before applying it.
With this being said, it’s also important to mention that you should use any weed killer with caution if you have kids and pets in your home. Another option, in this case, is finding a very good organic weed killer.
This way, you know for sure that you can deal with the weeds without exposing your family to harsh chemicals. However, these options might be a bit pricier or less effective on very tough weeds, so it also depends on what you need to deal with.
Q: What’s the difference between weed killers?
There are several types of weed killers that you can go for. The first one you might want to take a look at is the post-emergence product. These substances are generally used when the weeds have already grown too much and they need to be sprayed on. The way they work is by infiltrating the weeds and killing them from within.
Another type of weed killer consists of contact substances. Just as the name suggests, these work by coming in direct contact with the weeds. The only downside is that they don’t deal with the roots as well, so it’s best to use such substances combined with more permanent treatments.
The in-depth weed control solutions are pretty much the exact opposite of contact ones. The way they work is by entering the soil and killing the weeds from the roots. It’s true that they take a longer time to work, but the results they ensure are more permanent.
