Basic Knowledge You Need to Know About Lawn Weed Killer

The first thing that you need to learn about weed killers is that there are basically two main types depending on the emergence of weeds. These are:

Pre-emergent – This type of weed killer prevents weeds from germinating from seeds so as to keep the weeds from sprouting. If some of the weeds do manage to sprout, they will not take root.

Post-emergent – This kind of grass killer is best to control weeds that already broke through the ground. You do not have to spend the entire afternoon on your knees pulling out weeds. You just need to spend a couple of minutes spraying the annoying plants with weed killer for lawns and they would die on their own. The dead plants will also serve as a natural fertilizer for your grasses and your plants.

In addition to these two main types, weed killers are also grouped according to how they work, mainly:

Contact weed killers – This grass and weed killer will kill any and all plants that it touches. They are the most popular nowadays because you can see positive results within a span of just a couple of hours. The weeds will start to wilt and dry immediately.

Although these herbicides do act fast, they only affect the parts of the weeds that are above ground. They cannot remove the actual root system of the grass weed, which means it can and will sprout again. Contact weed killers are best for annual weeds (like bindweed, crabgrass, mallow, and nettle) as they spread via their seeds.

Systemic weed killers – Unlike contact weed killers, these herbicides are absorbed by the weeds’ foliage and then it would spread throughout the plant and through the root system. Systemic weed killers stop the growth of the weeds by inhibiting its ability to synthesize food from sunlight and get nutrients from the ground via their roots. This herbicide is best for common perennial weeds, like thistle, poison ivy, dandelion, and ragweed.

Other terms that you will see when you shop around for the perfect weed killer are selective and non-selective. Selective contact just means that it will not kill all kinds of vegetation that it touches. It might just kill the weeds and leave your established lawn and other plants alone (there is no guarantee that it will not kill some of your plants, so you better test a bit of it first).

On the other hand, non-selective weed killers can kill all kinds of vegetation, so you need to be careful when using them. The upside to using non-selective herbicide, though, is that they are more potent making them better when you want to control weed and grass growth.

To make things a bit more difficult, weed killers are not cheap. To ensure that you make the most economical and efficient choice of herbicide, you need to get up close and personal with the weeds that you actually wanted to get rid of by answering these simple questions.

What kinds of weeds do you have?

The most important thing that you need to know is what kinds of weeds are growing in your lawn and garden so that you can find the best weed killer for them. You need to examine the plants that are growing in your garden and find out what species they are.

Do you have a problem with annuals? These are the weeds that just live for one season, like foxtail and crabgrass. Or are perennial weeds invading your garden?

These plants are those that live all year round. These are the ones that are harder and harder to control as they regrow from the same root system. Perennial weeds include dandelions and nutsedge.

The great thing is that there are many free online sources that you can consult if you do not have any idea what these plants look like. For instance, the website of the University of Arizona has an extensive database of pictures of common weeds.

You can also just do a quick search on Google by typing in a short description of the plant in question.

If by some chance, you cannot find the information you need online, you can take samples of the plants to your local garden center and ask them to identify the plants for you. While you’re there, ask which weed killers are best for dealing with these pesky plants.

What is its intended purpose?

Are you just preventing weed growth? Or do you want to kill weeds that have already overgrown in your garden?

If you are looking for a weed prevention solution, then an application of pre-emergent herbicides during the spring will generally prevent them from sprouting up in your garden when their growing season comes.

The pre-emergent contact weed killer is quite an efficient crabgrass killer. You can also use it on other tough annual weeds.

If you observe that there are weeds that somehow grow at the same spot in your garden every year, their root system must still be in the ground in that area, and that is where you need to apply a liberal amount of pre-emergent weed killer.

On the other hand, if you want to control weeds that have already sprouted and are starting to spread through your garden, you need to use a post-emergent contact herbicide on them. When sprayed onto the invasive plants, post-emergent herbicides will seep into the plant and kill it quickly.

However, you need to be careful when buying post-emergent herbicides as they are usually non-selective, which means they will kill all kinds of plant life they come in contact with.

You will need to use a precision sprayer or a foam applicator so you can target only the plants that you want to get rid of. It is not advisable to use a wide spray as you might inadvertently apply herbicide onto your prized plants as well.

Post-emergent herbicides, though, are effective for places where you absolutely do not want anything to grow, like on your driveway, walkways, patios, around your fence posts, and other places.

How much herbicide do you need?

To figure out how much of the stuff you need to buy, you need to take the size of the affected area into consideration. If you are only thinking of doing a couple of spot treatments, like when you are just doing a bit of maintenance work on your otherwise pristine lawn, you can get a bottle or two of the “ready-to-use” weed killer.

These products are convenient because you just need to pop the lid off and pour the contents into your applicator of choice. There is no need for dilution.

On the other hand, if you will be treating a wide area, it is more economical to purchase the concentrated stuff. You need to be careful when handling herbicide concentrate though as they are very potent and fast-acting.

Also, you need to be precise with your measurements because if you dilute them too much, they will lose a lot of their effectiveness.

Once you have answered all of the questions above, you will know what kind of herbicide you will need, as well as an accurate estimate of how much of it you should get. You are now ready to face those pesky weeds that dared to invade your lawn and garden.

Homemade Weed Killer for Lawns

As mentioned earlier, some herbicides do not only kill the weeds in your garden, they also harm the plants growing beside the weeds.

In addition, they contain harmful chemicals in their formula that can harm the surrounding environment if they are not stored or disposed of correctly. Fortunately, you can actually make your own weed preventer concoctions using stuff you already have around your home.

Corn Gluten Meal

Before you apply the corn gluten meal, you need to pull out all of the weeds beforehand because this method will not have any effect on already grown weeds.

Once you have pulled out all the weeds in your garden, sprinkle a liberal amount of cornmeal over the areas affected by weed growth. This will suppress the development of the small feeder roots of weeds, thus preventing them from spreading further.

You can use corn gluten meal for almost all kinds of invasive plants like crabgrass, knotweed, dandelions, and others.

In addition, you can use corn gluten meal all over your garden because it does not affect the growth and health of already established plants, which means you can safely use it on your vegetable patches and your flowers.

Liquid Dish Soap

Combine 1 part liquid dishwashing detergent to 10 parts water in a clean plastic spray bottle. Give the troublesome weeds a couple of spritzes.

This technique works best during noon, especially on the hottest part of the day because dishwashing liquid tends to get sticky when it starts to dry up.  Moreover, it dehydrates the parts that it comes in contact with, which immediately kills the weed.

Vinegar

This method is quite simple. Just pour ordinary vinegar, any kind will do, into a plastic spray bottle, and spray it directly on the leaves of the weeds. The acid in the vinegar will dry out the leaves of the weed, which will cause the plant to wither up and die.

Some gardening experts still debate to this day if vinegar can actually kill the roots of the weeds as well, so just to be sure, just pull out the weeds once the vinegar wilts their leaves. It is a bad idea to directly spray vinegar into the ground as it can quickly change the pH level of the soil.

Salt and Vinegar

Combine 1-1/4 cup of salt with a gallon of white vinegar, and pour some of it into a plastic spray bottle. Adjust the spray nozzle to a tight stream.

Point the nozzle of the spray bottle on the heads of the dandelions then press the trigger. This will be enough to kill the plant. Be careful not to get any of this solution on the grass and the ground as this will kill the grass and render the ground acidic for years.

Of course, these homemade weed killers are not as efficient as the commercially-available stuff, but then again, if your weed problem is not that serious, you need not spend a lot of money on weed killers.

Weed Control for Lawns: Using Herbicides Safely

Herbicides may be designed specifically to attack weeds and other invasive plant matter, but that does not mean that they cannot do you harm. You need to be careful when handling all kinds of poison, herbicides included. So, before you use herbicides to get rid of the unwanted plant visitors in your lawn and garden, here are some tips on how to use them safely.

  1. Always read the label – You need to read the label of the herbicide completely before you even open the container. There are times when the included safety information and instructions are so long that there is a brochure that comes with the product. No matter how long it might be, you need to read and understand everything (maybe excluding the ingredient list). You might miss critical information if you skip reading the label.
  2. Use the necessary personal protection equipment Before you start, you need to make sure that you have all of the personal protection equipment mentioned in the label of the herbicide. For instance, you will need breathing protection when preparing the chemicals. Also, you might need to wear protective goggles to keep you safe from the fumes. You will find the complete list of PPE you will need to safely handle the herbicide on the label of the container.
  3. Do not use the measuring cups and other kitchen implements for preparing the herbicide Any household item that you use for the preparation of herbicides should never be used again for preparing food. Either you throw them out or relegate them strictly for herbicide use only.
  4. When diluting concentrates, do not add more than the recommended amount – Some herbicides have concentrated active ingredients and need to be diluted with another liquid, which is usually gallons of water before you can use them. However, you should not add more than the maximum amount of pesticide allowed on the label. Using more concentrated herbicide will not be better, and in some cases, it is illegal to do so as it can harm the environment. On the other hand, do not dilute it too much just because you want to save money. The gallons of water will dilute the effectiveness of the herbicide.
  5. Mix/Purchase the right amount of herbicide that you will be using – Do not prepare more herbicide than what you actually need. You need to estimate the amount of herbicide to use judging by the area affected by the weeds. If there is excess herbicide left in your pressure sprayer after you are done with the coverage area, do not just dump it down the drain. Put it in a canister and dispose of it properly. If you need to clean the sprayer, use a mixture of ammonia and water. The ammonia will neutralize the chemicals left in the sprayer.
  6. Remember that even “organic” herbicides are unsafe Even if an herbicide has the “organic” label, that does not mean you are allowed to be lax when using it. Organic herbicides are still poisons, which is why you should be very careful when handling them. Again, you should carefully read the label on the container for detailed instructions for use.
