Each weed killer is effective at targeting and controlling specific types of weeds.

Consider the ease of application when selecting a weed killer.

Some products are available to apply as a spray, while others are applied as granules.

Use sprayer, hose end sprayer for liquid herbicides or a broadcast spreader for granules.

Effectiveness of the Treatment:

Look for a product that’s proven to be effective with a good track record of systematically controlling weeds.

Professional strength products are usually more effective but have a smaller margin for error.

They must be applied to manufacturer’s instructions.

The products found at the home and garden stores like Lowe’s and Home Depot, often have similar ingredients as the professional options, just slightly diluted.

Cost and Availability:

You’ve done the research, and found a product; but can you find it in your area?

Often times, the products you want are not readily available.

Many manufacturers and retailers limit supplies based on regional distribution.

When you cannot locate lawn care locally, look online where you can order and get it delivered to your property location.



Pre-emergent vs. Post-emergent

Once you narrow down your choices, it’s time to decide if you want to simply kill existing weeds, or eliminate and prevent future weeds.

Lawn herbicides can be divided into two main categories: pre-emergent and post-emergent.


Pre-emergent weed killers stop weeds from growing by preventing them from germinating or killing them after they germinate.

They are most effective when applied before weeds start to grow.


Post-emergent weed killers kill existing weeds.

You can apply post emergents to get rid of the weeds that are already growing in your lawn.

Some common ingredients in weed killers include glyphosate, dicamba, and 2,4-D.

Dicamba is a selective herbicide that kills only broadleaf plants.

2,4-D is an herbicide that is effective at killing a wide variety of plants, making it a popular choice for lawn enthusiasts.

When using an herbicide that contains 2,4-D, be sure to read the instructions carefully and follow them closely, as it’s easy to apply incorrectly.


Avoid products with glyphosate. Glyphosate is a nonselective herbicide that kills both weeds and grass.

It is effective against a wide variety of plants, but it can also damage nearby plants if it is not used properly.

Weed killers are available as liquids, granules, or powders that each have specific steps for application.

Many professional service providers often use backpack sprayers and mechanical pump sprayers.

Make sure you measure properly.

Use the provided measuring devices, or buy your own measuring cups.

How To Apply Granules

Granules have to be applied with a broadcast spreader.

You’ll need a good broadcast spreader like the Scotts Spreader or Lesco Spreader.

Measure your yard to get the square footage, then apply based on the measurements.


Organic weed killer for lawns

Some herbicides use chemicals that can harm your plants and pets, so be sure to read the label before using.

There are many types of organic lawn weed killers on the market that are free from harmful chemicals, but which one is the best?

You can choose an all-natural product for your grass.

Organic weed killers work by breaking down the weeds’ cell walls, while others work by depriving the weeds of water.

Overall, the best lawn weed killer will depend on the type of plants you are fighting and your specific gardening or landscaping needs.



Do Not Use Glyphosate On Your Lawn Grass

One of the most important aspects of keeping a lawn healthy is ensuring that the grass is killed by the appropriate grass treatment.

There are a lot of plant products on the market, but not all of them work well on lawns.

The worst weed killer for lawns is glyphosate, which is found in Roundup.

Roundup kills almost all plants and grass by inhibiting photosynthesis, so the plant can’t produce energy and it dies.

It is non-selective, so it will kill any plant it comes into contact with.

That’s why you should always read the label before using any herbicide.


Update: There are now cultivars of St Augustine grass that can be sprayed with glyphosate to control weeds like Scott’s ProVista St Augustine. These new selected varieties of grass are not harmed by Roundup or other products.




There are several selective herbicides that can be effective in controlling many common lawn weeds.

The best herbicide for your situation will depend on the weed species you are targeting, as well as on the characteristics of your lawn.

Unfortunately, lawns can be tedious to maintain.

The right tools are important to have if you want to keep your lawn clean and free from infestation.

The best way to get rid of unwanted grass is with a selective herbicide.

A selective herbicide labeled safe for lawns will kill only the weeds and not the grass.
