Features Of Weed Killers
It may seem like a weed killer is a fairly straightforward product. They are cocktails of chemicals that are meant to kill the plethora of weeds that can affect your lawn without affect the grass itself. However, there are many different products out there.
The best defense against weeds is having a healthy, water, nutrient-rich lawn. Weeds tend to grow well in nutrient-poor, under watered soils that your grass does poorly in. Because there are so many species of plant pests, there are weed killers with a variety of active ingredients. Some types of weeds are better controlled by certain chemicals, and other types are better controlled by other chemicals.
Here is a helpful YouTube video that will show you the basics of weed control. In it, the importance of using weed killer in an environmentally friendly way is discussed, as well as how to decide which type of weed killer you need for your lawn.

Ortho Weed B Gon kills clover, dandelions, and over 250 other broadleaf weeds. When used correctly, its guaranteed not to harm your grass and can be used on many northern and southern lawns.
Unlike some other weed killers that can take weeks to see results, this product delivers results in hours, depending on the weed. Dandelions, for example, are gone within a few hours though some weeds may require an additional application. Plus, it kills weeds to the root which means theyre unlikely to return.
This 32-ounce bottle covers up to 16,000 square feet. Its perfect for spot treatments, too. Spray what you want, when you want, and save the rest for later. For best results, attach the sprayer directly to your garden hose and apply during periods of active growth. Its rainproof after one hour.

For spot-treating weeds, this 20% natural vinegar weed killer is one of the most effective organic solutions to single instances of weeds. It acts as a post-emergent, so do not expect it to act as a weed preventer.
What I like more about it is that it will get rid of both grassy weeds as well as broad-leaf plants.
Be careful when using this organic weed solution because it can easily destroy any plant it comes into contact with.
If your home has pets and kids that play in the yard, using this vinegar recipe to kill weeds is one of the best ways to guarantee their safety.

Best Ways To Kill Weeds In Flower Beds
Some weed killing methods such as Borax, lemon juice, vodka, and vinegar work best in areas where no other vegetation is around. The acetic acid found in vinegar provides vinegar with its unique taste but also kills most plants it comes into contact with.
Use vinegar and other techniques for killing weeds in sidewalk cracks or driveways. Its an excellent alternative to chemical weed control.
For flower beds and vegetable gardens, control broadleaf weeds with organic herbicides or other natural weed control methods. Applying a generous layer of mulch to garden beds is as effective as most organic weed killers in large areas. The best part about mulch and other natural methods is you wont have to deal with any toxic chemicals.
Best Weed Killer For Clover Dandelion
For weeds such as Creeping Oxalis, Bindii, Catsear, Clovers and Dandelion, a selective herbicide is the best choice.
The Amgrow Bin-Die weed killer is a great choice as it has been specially formulated for use on Buffalo lawns such as DNA Certified Sir Walter Grass.
However, if you need a stronger weed killer for weeds such as Wintergrass or Onionweed, a non-selective weed killer such as Yates Zeroaqua is the best liquid weed killer for lawns.
As it is non-selective, youll need to be very careful while applying it and ensure that it isnt going to rain in the next couple of days.

Understanding How Weed & Feed Products Work
Lawn and garden products known as “weed & feeds” get their name from two main components: herbicides that kill existing lawn weeds and fertilizers that feed lawn grass. Unlike crabgrass preventers, which contain “pre-emergent” herbicides that work against germinating weed seeds, most weed & feed products contain “post-emergent” herbicides, which focus on weeds that are actively growing in established lawns.
Weed & feeds vary in the common lawn weeds they target and the herbicides and plant nutrients they include, so it’s important to read your product label thoroughly. Common weed & feed products generally rely on “selective” herbicides that target specific broadleaf weeds, so lawn grasses stay unharmed. Some weed & feed products are most effective on weed parts above ground. Others kill top growth and roots, so weeds can’t spring back and repopulate your turf.
How To Apply Weed Killer To Lawns
Much like stump killer, improper application of weed killer can cause major complications to your lawn.
Proper application of weed killer to your lawn can make or break its effectiveness. There are several different application methods, and also several different considerations to make before you spray these chemicals in your yard.
First, the most common way of spraying weed killer is by putting it in a spray bottle and diluting the product with water. This both increases the longevity of your weed killer and also makes the product easier on the environment. Spray bottles are inexpensive and can be purchased at any home improvement store or online.
There are also several climate conditions that need to be right before you spray your yard. First, avoid using weed killers during drought conditions, as the chemicals in the weed killer can harm your lawn if its too dry. You should also only use weed killer when there is no rain expected for at least six hours, as the chemicals need time to be absorbed by the weeds.
Some weed killers are meant to be applied with a push spreader, as they are in solid form. Similar to how you would spread fertilizer, these solid weed killers are little pellets of chemicals that can be spread throughout your yard. You will need to buy a spreader for this, however.
