What Should You Know Before Buying a Weed Killer?

Before investing in the best herbicides or weed killers, it’s essential to become familiar about its different types first. Note that there are two common types of weed killer – the pre-emergent and the post-emergent. Understanding how each of these types of weed killer works can help you pick the most suitable one for your specific needs.

Pre-emergent Herbicide

It is crucial to note that this type of weed killer is incapable of stopping the whole weed germination process. What it does is that it interrupts the process prior to causing a sprout to push through a soil. One example of this type is a crabgrass killer and preventer, which works by preventing the seeds of crabgrass from growing new plants. If you’re planning to use this type then it’s advisable to treat the whole lawn area. Note that missing a spot might only cause weeds to sprout there.

Post-emergent Herbicide

You may also use the post-emergent herbicide if you’re planning to handle annual broadleaf and perennial weeds. These refer to weeds shaped like leaves but don’t resemble grasses. This type can also control weed and grass. You can pick the post-emergent type if you wish to control and kill the weeds in your lawn. It is also an effective choice during the start of the spring season when plants already begun to grow. Note that once plants begun growing, it’s a bit too late to prevent germination using the pre-emergent type, so it would be best to go for the post-emergent weed killer.

Aside from learning the two mentioned types, take note that weed killers also work based on two ways – the contact and systemic application.

  • Systemic – A weed killer for lawns that works using the systemic application tend to be brought by the foliage. It is then transported to the remaining plants, including the roots. The systemic lawn weed killer can be expected to inhibit the growth of weeds in a hormonal manner by minimizing the amount of chlorophyll and protein present in the plant. It often takes around two weeks for this type to eradicate the plants completely and produce visible results.
  • Contact – If you want to know how to get rid of weeds forever in a specific area then the contact weed killer is probably the best solution for you. It attacks a specific weed or some weeds that thrive in a specific area. It works by killing the plants only or their parts. It is also known to be fast-acting. It is appropriate for annual weeds. While it is incapable of killing the roots, it is effective in weakening the plants through repeated applications.

When trying to get to know more about weed killers, you may also come across the terms selective and non-selective. A selective weed killer won’t be able to kill all vegetation it comes in contact with. It tends to kill the weeds only while leaving the remaining grasses in your lawn. With that, it’s an ideal choice for you if you have an established loan. The non-selective type, on the other hand, tends to kill almost all that it touches. These include flowers, veggies, and grasses. This makes this type ideal if you want to clear some areas of your ground or lawn.

Factors to Consider when Buying a Weed Killer

Choose the Best Weed Killer

Managing weeds is actually a tough and challenging task for a lot of people because of several reasons. One reason is that these weeds tend to grow faster in comparison to beneficial plants. You can also expect them to survive in most soils and environmental conditions while starving your lawn of nutrients, causing the stunted growth of your plants.

If you want to find the most appropriate weed killer for your needs then this buyer’s guide will be of help to you. With this buying guide, you’ll definitely know the different factors that will contribute a lot in choosing the best liquid weed killer for lawns or the perfect herbicide for your unique requirements:

Targeted weeds

The first factor you have to consider is the specific type of weed you wish to target. Note that the best herbicide for you is that which is capable of killing the specific weed species that are thriving and invading your home and lawn. Before making your purchase, spend time examining the unwanted weeds and invaders that grow in your lawn or in any other areas of your home.

Among the weeds that you may have to deal with are annuals, such as foxtail and crabgrass. Your lawn may also have perennial weeds, such as dandelions, plantain, and nutsedge – all of which are more difficult to control when compared to the annuals. Research about the specific weed that you’re dealing with. That way, you can find an herbicide, which is really effective in doing complete weed kills and control.

Effectiveness

Another factor that you have to consider is the effectiveness of the product. Prior to buying, you have to conduct an extensive research about its effectiveness in killing weeds in your lawn. You will also learn about the effectiveness of the product by studying its main ingredients as well as reading legitimate customer reviews. The best product continues to receive positive reviews from its users.

Type

It is also crucial for you to decide on the type of weed killer that you have to use. Will it be the contact weed killer, which kills only those plants and weeds that come in contact with it? Or will you choose the systemic weed killer? You can actually make your choice between these two types by figuring out the majority of weeds and grasses that are presently thriving and invading your space.

Intended purpose

Before you make your purchase, it is also advisable for you to determine the specific purpose you wish the herbicide to fulfill. Is it going to be to prevent the emergence of weeds? Or is it to get rid of the already growing ones? In this case, you have a choice between the post-emergent and the pre-emergent herbicides.

If your goal is to prevent weeds then go for the pre-emergent type. However, if you want to target those grasses and weeds that are already thriving and growing then the post-emergent weed killer is right for you.

The amount of herbicide or weed killer required

It is also crucial to decide based on the specific amount of herbicide or weed killer you need. If you wish to treat a small area only then it would be more convenient for you to use a ready-to-use herbicide, which you no longer have to dilute with water. However, if you’re planning to treat a wider area with plenty of weeds then it’s advisable to pick a concentrated product, which is known to be more economical.

Avoid buying an herbicide without calculating the area you’re planning to treat first. This will give you an idea about the size or weight of herbicide or weed killer you specifically need. It also ensures that you won’t be storing too many herbicides in your home that you no longer need.

Ease of use

Another important consideration is how easy it is to use the weed killer. Avoid buying one, which requires complex steps when it comes to its use and application. You should have an easier time preparing it. Furthermore, it should have a straightforward application. That way, you can use it to manage weeds in your lawn and garden with ease.

Level of safety

Another thing that you have to do prior to buying is to check the formula and components used in the herbicide. It should have a high level of safety. It should be non-toxic and should contain non-irritating ingredients. If possible, go for a natural one, which is not harmful to the environment as well as to the people around your home and your pets.

Once you have made your choice, do not forget to read the instructions indicated on its pack carefully. Note that each product requires you to follow a different formula for blending water and ingredients so you really have to dedicate some time reading its instructions. You need to follow all the instructions precisely to guarantee a more successful experience when controlling and managing weeds.

DIY Weed Killer: Pros and Cons

As the name suggests, a homemade weed killer is a solution that you can prepare at the comforts of your own home using certain ingredients. Fortunately, it is not that hard to do considering the many DIY weed killer recipes that are now introduced on various sources, like in the internet. The majority of these recipes actually make use of certain ingredients that you can find at home, including salt, vinegar, and soap.

So what are the most commonly used weed killers that you can make at home? What are their pros and cons? Here they are:

Vinegar

One option for the best DIY weed killer that you can use is household vinegar, which has around 5% acetic acid concentration. What’s good about acetic acid is that it’s a desiccant, which means that spraying it on a plant’s surface will draw out the moisture from its leaves, thereby killing its top growth.

It’s actually effective if you’re dealing with invasive plants, like Canada thistle, and some weed species, especially young ones. However, it’s not that effective when used on more mature weeds and perennials with more developed and robust root systems because it only works in killing the topmost part of the plant.

Salt

Just like vinegar, you can also expect salt or sodium chloride to work as a desiccant. You can add this in a DIY herbicide recipe because of its ability to deal with those unwanted plants that vinegar can’t seem to kill. Salt is really potent and powerful in the sense that it works effectively in killing and getting rid of unwanted plants, grasses, and weeds.

However, it also has a disadvantage as it has a long-term negative impact on the soil. It also tends to negatively affect the roots of those plants that are close to the ones you’re targeting.

Citrus Oil

Citrus oil works as a DIY weed killer because of its ability to strip the waxy coating from weeds, causing them to get dry. It also contains d-limonene, an active ingredient, which tends to result from squeezing oranges right after removing the juice. It is beneficial, especially when used on pathways.

Another advantage of citrus oil is that it is easy to use and spray. It’s also safe to use around kids and pets. One problem with citrus oil is that it is not as strong compared to commercial weed killers. You might also need to use several doses of this solution just to produce your desired results in terms of killing weeds.

How to Use Weed Killer Safely and Successfully?

Once you have chosen the appropriate type of weed killer designed for the purpose you have in mind, it is time to start the task of controlling and killing weeds. But how can you do this task safely and successfully? Here are some tips designed to help you take control over your lawn through effective, safe, and successful weed control and management:

Read the label

Prior to applying your chosen weed killer or herbicide, it’s essential that you carefully read its label. The label will give you information about the specific purpose of the product, safety information, instructions on proper usage, disposal and storage, as well as its level of toxicity. It will also give you a clear idea about the protective equipment and clothing that you need to apply the weed killer. Make sure to stick to what’s instructed in the label to guarantee your safety.

Do not spray during an extremely hot weather

Again, check the label of the product to determine the best time and temperature to apply it. Follow it to avoid amplifying the stress experienced by your beneficial plants and grasses. Spray during wind-free days, too. Do not forget to wear gloves during the application as the chemicals in the herbicide might cause eye and skin irritation.

Carefully target the weeds

Do that, especially if you are planning to use a broad-spectrum weed killer, like those containing glyphosate. Since this type of herbicide has the tendency of killing the majority of plants it comes in contact with, you have to be really careful when targeting those that you want to get rid of. One way to handle this is to utilize a weed wand. You may also soak a cloth or sponge into the solution and paint the weeds with it instead of spraying. Such ensures that it will hit its target.

There should be no irrigation or rain within 24 hours after application

Twenty-four hours is usually the standard period of waiting before you can let the treated area get exposed to rainfall or irrigation. It is because most herbicides are designed to stay in the foliage for that period to work.

Before applying, check whether no rain or irrigation will happen so you can spray accordingly. During a hot weather, it would be best to water your lawn one day before the application of the weed killer as this will provide the area with more resilience.

Avoid mowing the lawn for 2-3 days prior to applying the weed killer

Note that this product needs to be absorbed by the weed’s leaves. If the weeds are short because of mowing then there’s a great possibility that it will only absorb less chemicals. If you need to mow the lawn then wait for a few days first after that before you start spraying.

With these tips, you have a higher chance of killing all the weeds in a safe and successful manner. Make it a point to attack them as early as possible so you will have an easier time fully eliminating them.

This action will show that the weed killer is affecting the plant. And then within two weeks, the plants’ color will change and start fading. After, they will die.

For the best results, you should try spraying enough amount of herbicide on the leaves and roots. The latter is going to absorb the concentrate and begin dying.

Now if you’re going to use a weed killer gel, it will stick to the unwanted plants, which will turn brownish, before dying within 48 hours.

How long does weed killer take?

It will depend on the strength or potency of the weed killer. If you’re going to use a stronger concentrate, you will notice it will work faster than a less potent one.

In addition, you can make use of a gel herbicide if you want it to work faster, too. It can stick with the plant and eventually kill it fast. Overall, the time it will take for the weed killer to work will depend on the potency and type of herbicide you’re using.

But for safety, you might want to take a look and compare your options on the choices we have listed earlier. Any of them is a great choice for a weed killer that works effectively and safely.

How to apply weed killer?

It is another common question among those interested to apply a weed control by themselves. First of all, take note of the types of herbicides. One is the pre-emergence types.

They are commonly used in established lawns in order to disrupt the life cycle of the weeds especially among summer weeds, some of the most stubborn. At the very least, pre-emergence weed killers stop the seeds from germinating.

But for the best results, you should time the application by spraying before the seeds start germinating commonly in the early spring. You can also reapply the weed control about eight weeks following the first spraying in order to help with the invasive weeds like crabgrass.

On the other hand, there are post-emergence weed killers that kill the weeds upon contact. They are absorbed by the plants, which eventually die. But for the best results, the weed killer will work best if applied to young weeds.

However, if you’re going to deal with established weeds, like woody shrubs, you can get a better result if you would cut the weed to the ground, and then wait for new shoots and leaves to appear.

When should you apply the weed killer? You might want to apply it during the dry weather. If not, the herbicide will be rinsed off by the rainwater from the surface for treatment. Also, some of the remaining effects will also be diluted, making it less efficient.

You should also think about a weather-timing situation, so you have to think about wind particularly if you’re going to apply nonselective herbicides or glyphosate, which can kill all the plants, such as flowers and vegetables.

On the other hand, a windy condition can create an herbicide drift, distributing the chemicals onto different areas and killing even the desirable plant.

Other things to remember to apply a weed killer:

Applying a weed killer must be based on a timeline. For example, you have to remember that some product will work within days but others within a weeks or even longer. In this case, you should consider your timeline when thinking about applying an herbicide.

What are your needs? For example, if you have to replant within a period of time for concerns like temperature changes, you should think about applying a weed killer earlier.

Also, you have to remember that some herbicides will leave residue, which might remain toxic to the plants for a couple of months. So before selecting a weed killer, you must check and read the label to find out the time it will take to work and the time it will stay in the garden.

When to apply pre-emergent weed killer?

It is important to take note when to apply a pre-emergent that gardeners usually apply in an already established garden or lawn. They are applied with one goal in mind – to disrupt weed life cycle.

At the very least, weed killers are stopping the weeds from germinating. However, you should time the application in order for the weed killer to work. For example, you should time its application before the seeds germinate like in the early part of spring.

In general, gardeners reapply it two months following an initial spraying in order to kill crabgrass and other stubborn weeds.

How long after weed killer can I plant grass seed?                                                 

Depending on the type of weed killer, you should know how long or when you could start planting grass seeds.

For example, the pre-emergence herbicides can target the weeds before they germinate, while post-emergence weed killers can target developed plants.

Before seeding, you must use a non-selective and post-emergent herbicide that will control any weed in places to be seeded. Many of these weed killers can be sprayed or applied for up to two weeks before seeding begin in order to control current weeds.

On the other hand, you should not use herbicides after the seeding, not until the young seedlings have become established. You can do spot treatments and mowing to control the weeds after the seeded areas is growing actively and only needs maintenance watering. Take note that the establishment times will vary based on the seed type and the weather conditions.

Why should you wait before seeding? Feed and weed products can prevent germination or get rid of a living plant, so you should take note that it can have a similar effect on the desirable plants.

On the other hand, there is a pre-emergent herbicide siduron that can help in germinating. But when using one that doesn’t have siduron, you should wait for at least two months before replanting or seeding.

But then, if you’re going to use a weed killer for broadleaf weeds, you should read and understand the label carefully because its active ingredient might need a longer waiting period.

In some cases, you can start seeding in as little as a month following an application if using a weed control with 2,4-D, but up to six months if using products with atrazine.

When to put weed killer on lawn?

You can put weed killer on the lawn depending on several factors, such as climate, temperature and landscaper timeline as mentioned earlier.

For example, the weed control might work slowly if you’re applying the moist or cold atmosphere. It might also damage vegetation if you spray during this time, too.

For the best results, you might want to spray in a sunny and warm day when the weeds are going to absorb the weed control faster and easier while the remaining concentrate will evaporate.

Applying weed killer won’t also harm the desirable plants and flowers during this time. It will also work more effectively than spraying or applying a weed killer in a cold or moist day.

Is weed killer dangerous to dogs?

It will take about 48 hour before it is absorbed into the soil and grass. For this reason, their chemicals, if you’re not using a natural and organic, can be toxic for the pets that can be playing, walking and eating in the grass, which they tend to lick, too.

In some cases, pets also have their water bowls, which can be placed outdoors potentially in or near the grass. Thus, they can be exposed to the toxic chemicals.

And again, if not using organic weed killers, the chemicals from those treated lawns can be transferred to the untreated lawns. As a result, they can also contaminate the pets, which will pass through or nearby the treated yard. In addition, the chemicals can also be transferred to other pets or to people.

To protect your dog, you should keep him away from the treated lawn or garden if it is treated with chemicals until the weed killer has been fully absorbed.

You should also wash your pet’s lower body, including the legs and belly area, assuming they contacted the treated lawn. Put the water and food bowls and the toys away from the treated area.

You should also avoid weed killers with carcinogenic and toxic chemicals in them.

Finally, you can use alternatives in treating the lawn. For example, you can increase the grass’ growth wit organic and slow-release fertilizers. You might also want to use chemical-free and organic ways in treating the garden in the summer.

Why can salt be used as a weed killer?

For centuries, salt has been used as a plant killer. Today, it is still used as a weed killer but in a smaller quantity. Some people use and mix a bit of it with water to make a solution. Then, they apply it to the base of the undesirable plant, which will die in a few days but without harming the plants.

Salt can kill weeds by drying out the cells of the plants because it can suck water out of the roots, resulting to the wilting and dying of the plant in a day or two. When the rain comes, though, the salt will be diluted and safe for the remaining plants. It should harmlessly be dispersed.

Using it once or twice is okay, but not if too much of it is used. It will eventually harm the soil that won’t also be good for plants. In addition, too much salinity will stunt and weaken the plants in your garden; thus, they can be prone to acquiring various diseases.

Where to buy weed killers?

There are many places to buy weed killers. It can be in the local gardening and landscaping stores, The Home Depot, Lowe’s and Walmart. But then, if you want convenience and a wide range of choices, you might want to go for online marketplaces.

So far, the best among them is Amazon where to find the best deals and buy safe, effective and eco-friendly weed controls from the manufacturers themselves. It is also the best online marketplace to search for great brands and buy at affordable prices.
