How to Kill Weeds in Your lawn CHEAP

Dont fancy doing it by hand?

But also dont want to use a chemical weed killer in your garden?

Here are some natural methods that are easy to get started with:


Watering weeds with a salt solution is a cheap and effective to kill weeds in your yard.

It changes the balance of water in their cells, dehydrating them and leading to death.

So why isnt it more popular?

Well, theres just one problem: it doesnt only kill weeds. And if not applied carefully it also makes the soil unsuitable for anything else to grow.

This makes it a good choice for using on patios, driveways, and sidewalks any area where plant life is unwanted.

But not such a great choice for ornamental gardens and lawns.

If you do choose to try it in areas where youre growing other plants, try using a funnel to direct the saltwater onto the target weeds.

And make sure you use a weak solution with around a 3:1 ratio of water to salt to start with. Observe your results and increase the strength if necessary, being careful not to overapply to areas of soil.

Boiling Water

Another method is to douse the weeds in boiling water.

Needless to say, this will kill grass and everything else you pour it on. Making it okay to use on the cracks between patios and driveways. But a poor choice for using on your lawn.

Sometimes you might have to apply the water a number of times to kill particularly stubborn weeds.

    Its best not to jump the gun when using weed killers. Theres a lot of weeds in early spring that wont surface until later on in the year. Most weed killers are contact sprays: The treatment will only be effective if they make direct contact with the weeds. Youre better off waiting until May: By that time most of the weeds will have emerged, making them much easier to dispose of.

Ready to use products are more expensive to buy but are dont require mixing and may come in a container with an attached sprayer.

    Spot Treatment Is Better Than Broadcast Application

    Ortho® WeedClear Lawn Weed Killer Ready

    Its no surprise that manufacturers of lawn care products, many of which publish a lot of online advice articles, insist that applying lots of chemicals over the entire lawn is the best way to control weeds. Their advice begins with broadcast application of pre-emergent herbicides in the fall or early spring, and continues with at least one, and preferably multiple, widespread applications of post-emergent herbicides at different intervals through the spring.

    The advice becomes much different when you consult academic sources, such as the lawn-science departments at various universities. These scientific experts understand the dangers that over-application of herbicides, pesticides, and chemical fertilizers pose to water sources through run-off, and here the advice is always to treat weeds in the least toxic method possible, avoiding broad applications of chemicals whenever possible.

    Instead, they argue it is best to avoid chemical means if possible, and if they are unavoidable, to spot-treat individual weeds with a spot-targeted spray rather than to spray or spread a dense layer of chemical over the entire lawn. Spot-treating weeds may sound like a lot of work, but a homeowner soon finds that its not a great burden to follow weekly lawn-mowing chores by walking the lawn with a hand sprayer and applying a small dab of weed killer to the weeds that are spotted. Over time, as most of the weeds are killed, it becomes relatively quick work.

    Weed Identification And Herbicide Selection

    After these cultural problems have been addressed, the weeds of concern must be accurately identified so that the appropriate herbicide may be selected. Proper weed identification is very important because understanding the weeds life cycle is the key to weed management. Herbicides vary in their effectiveness in controlling specific weeds, and some may not provide any control against the targeted weed. Choosing the wrong herbicide due to a misidentified weed can easily result in large amounts of money spent with no control of the weed. Common Weeds and Wildflowers is a complete, up-to-date weed identification guide available from the Cooperative Extension Service. The local Cooperative Extension agent or the Home & Garden Information Center can also help with weed identification, and determine which herbicide will be most effective based on research data and herbicide label information. They can also point out possible concerns when using a specific herbicide. These may include wind drift to nearby plants, volatilization problems, spray water pH and water quality issues, potentially harmful application over root systems of nearby woody plants, and requirements to apply the herbicide during a specific growth stage of the turfgrass or the weed to be controlled.

    Types Of Different Weed Killers: How To Apply Them At The Proper Time

    Herbicides are recognized either as pre-emergent or post-emergent. Post-emergent herbicides, which may be systemic or non-systemic, are used to control existing weeds. Herbicides that pass through vegetation to the roots are known as systemic herbicides, and theyre most successful while the plants are actively developing.

    Plant tissues are damaged by non-systemic herbicides, which can be spread at any time of day. Pre-emergent herbicides may be used at any time of day and are still effective. This herbicide works by forming a chemical membrane in the topsoil that keeps weeds out.

    1) When to apply a systemic herbicide

    Systemic weed killers are most effective throughout the planting season, and they are ineffective after the weeds have finished growing and gone dormant. The efficacy of systemic herbicides is increased when they are applied at peak plant growth periods during the day. Plant development speeds up and reduces during the day, based on the amount of sun, temperature, and environment.

    In warmer climates, such as the U.S. Department of Agriculture plant hardiness zones 9 and higher, the safest hours to apply systemic herbicides in the summer are early morning and late afternoon. In the season, avoid using herbicides during midday or early afternoon. Plant development slows during the midday sun, and herbicides soon dry out on the plants, decreases the quantity of herbicide that weeds absorb.

    Strengthen Lawn For A Stronger Defense

    One major contributor to weed control is lawn care. Lawns that are healthier develop deep root systems and are better equipped to handle weeds on their own. What constitutes a healthy lawn, and how can you use this information to remove weeds permanently from your yard?

    Despite popular belief that a shorter yard is healthier, its essential to let your lawn grow in just above three inches, which is just enough length for the grass to soak in more sunlight and develop more extensive, healthier root systems. With one simple adjustment to your mower, youre already on the fast track to improving growing conditions.

    Mowing your lawn regularly is also an excellent weeding tool, as trimming the tops of many common weeds weakens the plant over time.Another critical factor to consider when handling weeds is to aerate the soil. Do not do this while you still have weeds, since this spreads the weed seeds to other parts of the lawn.

    However, this is an incredible preventative measure to take when improving the soil conditions by providing better airflow and more nutrients. A similar process also aids in duckweed removal in ponds by perforating the top of the water to prevent water from becoming stagnant.

    After the recent warm weather, I am beginning to see signs of life in my yard. I am also starting to get calls from homeowners with questions about weed and feed fertilizers, and when is the best time to apply them to the lawn. The answer depends upon the type of weed and feed fertilizer you get.

    Fertilizers that contain weed killers are divided into pre-emergent and post-emergent. Pre-emergent herbicides, as the name suggests, prevent weed seeds from germinating. With pre-emergent weed killers, it is critical that the material be applied prior to weed seed germination.

    Choosing The Right Pre

    Some of the best chemicals for pre-emergent weed control include trifluralin, bensulide, DCPA, dichlobenil, oryzalin, and simazine.

    These are the active compounds that lawn companies use to kill weeds before they germinate. They are marketed for controlling broadleaf weeds like clover and Black Medic as well as grasses, and they are commonly used around flower beds, trees, shrubs, and even crops.

    If you dont have access to a landscape supply company, then you can also look for these chemicals in the products available at your local hardware store, or .

    In agricultural applications, farmers can use pre-emergent herbicides such as Avadex Liquid EC, Fortress Microactiv, Edge Granula, or Valtera to prevent weeds from popping up in their crops. The selected chemical can depend on the type of crop being grown, and if youre interested in these products you may be able to find them at your local farming supply store.

    If youre hesitant to use harsh chemicals like this on your property, youre not alone. You can avoid these and still effectively prevent weeds by using corn gluten an effective natural pre-emergent herbicide. Espoma makes a good product, but like anything you have to get your application timing and distribution right to see good results.
