Contact Weed Killers
If you notice an invasive weed taking over your lawn, reach for a contact weed killer. We cannot recommend this type for gardens or on plants that you eat or touch because it remains in the environment for months or longer. Contact killers work faster than any other type of weed killer and can eliminate some plants in as little as 24 hours. There are selective types of contact weed killers you can buy that work on certain types of plants but not on others. When you want one that works on all the weeds in your lawn, you should look for a non-selective product.
Systematic Weed Killers
When you find yourself struggling with weeds that won’t stop growing, consider using a systematic weed killer. It’s designed to kill weeds from the inside out. The way it works is quite simple. You’ll spray or apply the substance on the leaves and any other spots that you can see. The leaves will then transport the liquid through the branches and into the roots, which will then carry it to all other parts of the plant. One of the issues of using a systematic killer is that it can spread to other plants.

Many customers have questions about the environmental impact of using herbicides and similar products to kill weeds. Any time that you use chemicals outside, you risk those chemicals reaching your water supply. The chemicals can even get inside cracks in your pipes and affect the water that your family drinks. There is a risk of the chemicals contaminating the groundwater and affecting those who live near you too. Herbicides can also make your pets and your children sick, especially if they play around or touch any of the products you use on your lawn while those chemicals are still wet.

Weed killers typically work in one of two ways. These products can kill the weeds growing above the ground and force liquids deep inside the weeds to kill the roots underground. Weed killing products can also seep through the ground to kill the weeds from the roots up. As you look at the top products for sale, you will find that companies use certain words to describe how those products work. Those words can include:
Before you apply weed killer, you need to make sure that you get to the root of the problem. You’ll want to identify the types of weeds growing in your lawn to ensure that you purchase a product that will work on those weeds. Our top weed killers 2020 choices work on hundreds of different weeds and will target growth in regions across the country. Use a gardening hoe or a similar tool to lift larger or heavier weeds to expose the stalks beneath. Though you can pull up those weeds by their roots, you can also use a product designed to penetrate their roots to save yourself some time.
Hold the sprayer as close as possible to the weeds as you spray. Depending on the type of sprayer you choose, you may need to pull the trigger multiple times to thoroughly coat the weeds with the liquid. When you use a professional or commercial sprayer, you can hold down on the trigger to release a steady stream of water.
If you have weeds that keep coming back, consider cover those areas with mulch. Mulch will actually suffocate the plants to keep them from growing.
Keeping your lawn at the proper height will reduce the risk of seeds that grow into weeds from thriving in your lawn.
The most common ingredient found in weed killers today is Glyphosate. Manufacturers use a different amount of concentration of this ingredient. As it kills on contact, it is common in spot treating products that you spray directly on an affected area of your lawn. Many companies use a combination of Trifluralin and Benefin on annual weeds, which are weeds that grow and die within a single year. Benefin works especially well on crab grass, which can thrive in almost any region of the United States.
Those searching for environmentally-friendly weed killers will want to look for products that use natural and organic plant oils. You may find products that have eugenol listed in their ingredients. Eugenol is another word for clove oil. It is the same ingredient used in many over the counter dental pain products. Clove oil comes from clove buds that companies harvest. It kills on contact and will also reach into the root system of most weeds. You can also look for environmentally-friendly weed killers that contain lemongrass oil. Lemongrass is very effective at killing weeds but will not harm the environment surrounding your home.
Some shoppers like the convenience that comes from a ready made product. They can grab the bottle and spray it anytime they see any weeds. Concentrated products come with a set amount of liquid that you mix with water and use inside a sprayer of your own. Once you look at the benefits of concentrated weed killers, you’ll find out why so many prefer these products over ready to use weed killers.
Don not water your lawn or any surrounding plants for at least 24 hours after applying a weed killer.
Top 3 Ways to Control Weeds
Properly fertilize your garden to prevent weeds from taking over.
Make sure that your lawn has all the water that it needs, even during drought season.
Use insecticides to kill insects and bugs living outside.
A common mistake that some gardeners make is that they look at the price of a weed killer and choose the cheapest one. It’s helpful to consider the price per ounce or how many uses you can get out of a single bottle. The cheapest weed killers may only provide one application. If you spend more on a larger container, you might get three or more applications out of the bottle. Roundup retails for around $22 per bottle and comes with 1.33 gallons. EcoSMART gives you 64 ounces of weed killer for a little more than $20, which makes it one of the more affordable options.
Ortho also gives you one gallon of weed killer and sells a product that retails for $32. The concentrated formula provides multiple applications and provides results that you’ll see in hours. Compare-N-Save retails for around $20 and gives you one gallon of the concentrated formula. Weed Stop is the most expensive product based on upfront costs as it sells for $41. You get six bottles of the concentrated formula though and 32 ounces of weed killer in each bottle. When you buy a concentrated formula, you’re also responsible for other costs, including the protective gear that you wear and the sprayer you use to apply the liquid.
A: The best time to use a weed killer is in the early autumn or the early spring. Treating your lawn in the early spring helps you kill new weeds. Waiting until the fall lets you kill weeds that would otherwise come back in the spring.
A: Some of the top products on the market will begin working in as little as three to five hours. If you spray in the morning, you’ll see results when you come home from work. Other products take 24 hours or more to begin working. It can take several weeks and multiple applications before you get the results that you need.
A: You can apply a weed killer without exposing the roots first. Many products will kill on contact and then move through the weed’s stalk to reach the roots. You can kill ground cover plants that work as part of a larger system without exposing the roots too. If you find that the plants keep returning, you can spray the product directly on the roots.
A: Weed killers can be toxic or poisonous to pets. If your dog or cat ingests or comes into contact with an herbicide, you might notice symptoms that include diarrhea, lethargy, problems breathing, weakness and vomiting. Some dogs may have chemical burns in their mouths or have problems standing and walking.
