What does a crabgrass killer do?

Like a lot of other weed killers, crabgrass killers get rid of weeds and (depending on the formula) can also stunt their growth.

While these are particular herbicides are formulated to target crabgrass, the best crabgrass killers also have broader uses, with many having the capacity to kill 200 weeds or more.

Some of these herbicides work best on lawns, such as granules, and are specifically designed to suppress the growth grassy types of weeds. Since these products are “selective,” they can put an end to these weeds without killing the grass in your lawn, in essence, functioning as a kind of crabgrass control.

How does crabgrass killers work?

How a crabgrass killer works depends on the kind of formula used. Some post-emergent measures, actually create a chemical imbalance in the weed.

The herbicide acts like a chemical called Indole Acetic Acid (or IAA). Too much IAA actually forces the plant to rapidly grow (which explains why sometimes it can seem like the plant is still growing after application) until the plant literally gets too big for its own good, at which point it will die.

Other types of herbicides work by blocking photosynthesis, which not only blocks off the weeds energy supply but also leads to a build up of toxic chemicals inside the weed, which quickly kills it off.

Finally, natural herbicides, like citrus oil, work by stripping the weed of moisture, essentially dehydrating the weed to death.

How to apply crabgrass killer on your lawn?

Know that you’ve found the best crabgrass killer, you always want to follow the instructions that come with your particular product. Applications can vary depending on the kind of formula being used. For example, some products are concentrates, which need to be diluted with water and then applied directly to the plant in spray form.

Others are granules, which you simply spread on your lawn using a spreader. Since most granules act as pre-emergent solutions, you may have to apply it to wet grass in order for it to kill weeds, depending on the formula.

The most important thing to keep in mind when applying any herbicide, however, is to never over apply the treatment—especially on your lawn.

Make sure to carefully follow the instructions listed on your product, and wait for the suggested amount of time (anywhere between one week to 45 days) before applying the second application if it's needed.

How long does it take to effect?

Crabgrass killer can take anywhere between anywhere between 1 day to 10 days or more to work, depending on the product.

Since grassy weeds are typically tougher to kill because they spread faster, you may find it necessary to make several applications over a period of weeks or months.

Following the product instructions should give the best and fastest results.

What are the types of crabgrass killers?

If you’re not sure how to kill crabgrass, there are types of crabgrass killers: pre-emergent and post-emergent.

Pre-emergent killers prevent the growth of more weeds. Typically, they work by stopping the germination process of seeds. When seeds come into contact with this formula (usually in the form of granules) they become unable to germinate and therefore grow.

On the other hand, post-emergent solutions work to terminate weeds after they’ve already started growing.

Using these two types of treatments together can significantly reduce any weed problem over time.

How to use crabgrass killers without killing grass?

The big secret that most people want to know is how to kill crabgrass, without harming other plants.

The key to not destroying your lawn is to apply these products in moderation.

Although many crabgrass killers are selective, too much of these solutions can kill your lawn.

Additionally, carefully read the warnings that come with your product. Many herbicides of this nature cannot be used with particular grass types (such as St. Augustine).

If you’re not sure if a particular product will work for your lawn, try testing it out on a small patch and carefully monitor the effects. If, after a few days, you see no changes to the grass, continue using the product.

On the other hand, if the grass begins turning yellow, it’s a sign that you need a different product.

How frequently should you apply crabgrass killer on your lawn?

Remember, when it comes to herbicides moderation is key.

Ideally, you want to be applying both pre and post measures one every season. However, for really big weed issues this can be simply not enough.

In such cases, the best idea is to not apply more than once every 45 days. Applying prior to that time frame can actually lead to a build up of the herbicide on your lawn, which can kill your grass.

How long before pets can walk on the grass after applying crabgrass killer?

As with most herbicides, pets should be able to go out on the lawn after the product has dried.

Of course, this matter can be greatly dependent on the weather. On really hot days, herbicides can take as little as half an hour to an hour to dry. On cooler days this can take as much as 4-6 hours.

The best way to know if the lawn is safe for your pet is to simply test the grass before letting them out. If still seems damp, it’s probably a safer bet to wait for more time.

As a rule of thumb, it’s usually pretty safe to let pets out on the lawn 24 hours after application.

Conclusion

Crabgrass killers are a great solution to getting rid of a very stubborn weed. In fact, regular use of these products, such as once every season, can significantly reduce the weed’s numbers.

Keep in mind that preventative measures, such as pre-emergent treatments, are especially worth their weight in gold when it comes to battling weeds because it stops their growth.

Using a combination of these treatments can save you time, money, and a ton of frustration. It can also save you the effort of manually picking weeds.
