A weed-free lawn is the ultimate wish of every homeowner. There are things you need to know in choosing the best weed killer to kill those unwanted plants.
You’ve spent days, weeks and even months nurturing your lawn then out of nowhere lawn weeds start sprouting out. What a disappointment! Any plant that is an unwanted growth in your lawn is a weed which is rooted in the soil. Weeds can also get planted in your lawn by the birds, the wind and even from your feet! When you are tending a lawn, you will definitely have to deal with weeds and the only question left unanswered is when these weeds will start to appear.
There are a lot of products available you can use to kill all those weeds in your lawn. Before choosing any product, read on and learn everything you need about lawn weeds and how to effectively deal with them. As with anything that you buy, nothing beats an intelligent choice. A well-manicured and weed-free lawn is always a sight to behold.
Why Weeds Still Grow Even After All the Cleaning
No matter how meticulously you tend to your lawn, you will surely need to deal with lawn weeds. There are no ways to stop weeds from growing in your lawn. Weeds grow whenever they find a space for their roots to grow. They thrive on soil that provides the best environment where they can germinate:
- Compacted soil due to over-tilling.
- Hard soil such as clay.
- Wet soil.
- Sun-drenched areas.
- Shaded areas.
- Thinning grass due to disease or insect infection.
- Wrong mowing, irrigation and fertilization methods.
Different types of weeds grow in a different environment. You can try to pull weeds out, but they will keep on coming back. You can lessen the growth of weeds though. You can even get rid of them for good. Well at least for the meantime. A thorough understanding of weeds will help you in choosing the best ways to attack them.
Identifying the Type of Weeds That You See In Your Lawn
The thing with lawn weeds is they are at first invisible. By the time you notice their appearance they have already matured and are ready to reproduce! Most lawn weeds grow from their seeds, stems or underground tubers. To effectively combat lawn weeds, you need to know the types of weeds you are dealing with. Correctly identifying the type of weeds in your garden will be a big help in choosing the right weed killer product to use.
- Broadleaf Weeds: They are easy to identify because they do not look like grass. They stick out in your lawn like a sore thumb. They are feisty and strong. They thrive on lawns that have compacted soil and lack nitrogen fertility. (e.g. Dandelions,White Clover, Ground Ivy, Yellow woodsorrel, Spotted Spurge).
- Grassy Weeds:They look exactly like grass but do not contribute to the quality and good appearance of the lawn. Although they are weeds, they are maintained in some lawns. Bermuda grass is a weed when it grows in a fescue lawn, but there are some who use Bermuda grass on their lawns. Each year they grow from seeds and eventually die when their growing season ends. (e.g., Crabgrass)
- Nutgrass / Sedges.:They somewhat look like grass but are troublesome weeds. They are tubers that resemble nuts. They thrive on wet lawns and are one of the most irritating weeds that may grow in your lawn. (e.g., Yellow Nutsedge)
There are weed killers that can eliminate each of these types of weeds. Some weed killers attack a variety of weeds while some are specific to a particular weed type.
Harmful Effects of Weeds That You Need To Know
Weeds make lawns unattractive. However, there is more to weeds than just being unsightly.
- Weeds absorb water, nutrients, and sunlight that are intended for grass. Since they grow in astounding proportions, they often take in more potassium, nitrogen and phosphorous. Lack of these nutrients will make grass susceptible to insect infiltration and diseases.
- Weeds steal space otherwise intended for grass to grow. They are deadlier than insects and diseases.
You need to control the growth of weeds before they can create havoc in your lawn.
Winning Over the Uncontrollable Growth of Lawn Weeds
Winning over lawn weeds can be a daunting task. It is, you may think, impossible to stop a Dandelion from infiltrating your lawn when one of them can produce about 15,000 seeds which can survive for at least six years. To add to that, every Dandelion that matures can again produce 15,000 more seeds each!
When you decide to have a lawn, you must know that you have to deal with weeds. While weeds can cause you so much stress, there are surefire ways to win over them.
- Use the right amount of fertilizer. Weeds are more aggressive than grass. Too much fertilizer will nurture the growth of certain weeds. Too little fertilizer will make grass loose over weeds. Follow the instructions on the fertilizer boxes to ensure that your lawn gets more fertilizer than weeds.
- Water your lawn less but deeply. Sprinkle grass with about one inch of water each week. Watering too little but frequently will allow weeds to germinate more.
- Mow your lawn at a height that is best for your grass type – between two and four inches is the most ideal. Mowing too low allows light to penetrate the surface of the soil easily. This condition is best for weeds to grow.
- Hand-weed your lawn all the way down to the roots. It may be tedious but it works best when soil is moist.
- Use a weed killer (Herbicide). Depending on the state of the weeds in your lawn, you can choose between Pre-emergence Herbicides (weed seeds have not yet sprouted) and Post-emergence Herbicides (weeds are actively germinating).
Learn the Different Types of Weed Killer That You Can Use
Taking good care of your lawn can be an exhausting task. However, it is important that you do it to eliminate unwanted growth that could otherwise ruin your lawn’s aesthetic beauty. Not to mention the fact that the uncontrolled growth of weeds can ruin soil quality.
A weed killer is a chemical or non-chemical based product that works to kill weeds or control its growth. Choosing the right weed killer to work with is the hardest part when you are embarking on a weed-killing project. Choosing the first weed killer, you set your eyes on will not make the job any easier. There are certain things you need to know before you are finally able to choose the best weed killer.
Identify the type of weeds in your lawn.
Weed killer products are extremely useful because they are made to suit different situations. There are weed killers that can attack all types of weeds and there are some that are only for a particular kind of weed. To avoid disappointments, it is important to identify the type of weed growing in your lawn first and then choose the best brand of weed killer to deal with them. Read the labels carefully. Some attack only grassy weeds while some only work effectively with broadleaf weeds.
Assess the extent of the weed problem.
Does your lawn have small areas with weeds or have the weeds taken over almost your entire lawn? Small areas with weeds may only require a non-selective spray weed killer (suitable for all types of weeds). Make sure though that while spraying you protect the good grass. If your lawn has been totally won over by weeds, the strongest weed killer is your best remedy. Be aware though since those strong weed killers will cause the areas to be bare once you remove the dead weeds.
Understand how does weed killer work
It is important that you are familiar with the active ingredients in weed killers. This knowledge will help you know the effectiveness of each chemical as well as the level of toxicity. It will also help you be aware of what to expect when using weed killers with such ingredients. Here are a few of the common chemicals found in weed killers: 2, 4-D. This comes in acid, ester or salt chemical forms. The toxicity level of this chemical depends on what form it comes in. This chemical is often used in big lawns.
- Clopyralid. It’s a common chemical for killing broadleaf weeds, as well as turf plants.
- Corn Gluten Meal. This chemical is used for pre-emergent weeds and is only for light applications.
- Dichlobenil. A toxic chemical used during post-emergence in small lawns.
Study each weed killer brand.
Not all weed killer brands are made the same. If there are effective brands, there are also those that are not. Reading the labels are sometimes not enough. A little research would go a long way. Read some testimonials and product reviews.

Kill the weeds while being mindful of the environment. Organic weed killers may be slightly more expensive than those that are chemical based, however they are the safest to use.
Heard of 2, 4-D Weed Killer? And How It Works?
Well, this chemical is actually one of the most common chemicals found in weed killers. This works by stopping the growth of weeds which would eventually lead to their death, that simple. But you do not need to worry about its toxicity level because the toxicity depends on what form it comes, like in an acid, ester or salt form. That is why this chemical is often used in big lawns.
However, 2, 4-D is not the only chemical that will kill weeds. You will also be able to find other useful chemicals such as Clopyralid which is common for killing broadleaf weeds, as well as turf plants; Corn Gluten Meal that is used for pre-emergent weeds and is only for light applications; and Dichlobenil which is used during post-emergence in small lawns.
How a Weed Killer Spray Works
There is no best time to kill weeds. Any time of the year is the best time. Weed killers work best though when weeds are actively growing in your lawn. This is the time when weed killers work the fastest. The day should be calm and not windy when you are working with weed killer sprays. This will avoid or minimize the solution from hitting good grass.
Most weed killers need to be diluted after which they can be loaded into hand sprays, pressure sprayers or a watering can. Then, always read the label, to ensure that you are using the right tools (sprayer or watering can).
Be Mindful of the Environment – Go Organic
There are numerous organic substitutes for chemical-based weed killers. Organic weed killer sprays though can cost more than chemical weed killer sprays. But if you have kids and or pets at home or you’re very conscious of doing your share in protecting the Earth’s ozone layer, then you won’t mind shelling out a few extra dollars for an organic weed killer spray. Most organic weed killers are non-selective and are for broadleaf and grass weeds. The beauty of organic weed killers is that they only attack the object that it is directly sprayed on.
If you are going organic with your lawn weeds, you have two options. First, you can choose between citrus oil, herbicidal soaps (more refined than dish soaps) or vinegar-based organic weed killers. Organic weed killers attack the protective layers of the weeds causing them to dehydrate and eventually die. Second is, you can hand-weed your lawn! Pull them out with your hands or with a weeding tool.
