The Best Crabgrass Killer Buying Guide

There are several factors on which the high-quality crabgrass killer that will be perfect for your need will depend. Your reason to purchase the crabgrass killer can be targeting different kinds of weeds or if you want to apply it during the dormant or growing season etc. 

Homeowners must be considering the fact if they are looking for something that will kill the crabgrass in the established lawn or the one that’s recently seeded. Here is the list of the options for making sure that you can narrow down your options with ease:

Nonselective or Selective?

All of the herbicides that you get in the market have a nonselective or selective formulation. The selective ones will be controlling specific categories of weed, for instance, “grassy weed”. The ingredients present in it will be safe for the non-targeting plants while they will be able to kill the target weed like crabgrass and dandelions. 

Make sure that you are reading the labels well over the selective herbicides for being sure that it is the right product for you. A product that has the label “Grass Weedkiller” might not be able to control the crabgrass. 

Then the non-selective herbicides will be killing all of the plants that it is sprayed on. This is mainly useful for places where there isn’t a need for plans at all, for example, driveway cracks. These are mainly used for helping the land to get prepared for renovation, like the creation of a flower bed. 

Will the product kill or prevent?

When you go through the crabgrass killers you will see that the product will be able to have two different working methods. You should also be able to understand how often the product has to be applied. In case you are in search of a product that prevents and also kills the crabgrass, you should know that this can be expensive and see the budget that you have in mind. 

The Vegetation Around

Some of the Best Crabgrass Killer Analysis that you see on the list give you the option to select a product that isn’t going to influence the edibles of the garden. However, a good idea can be to go for the herbal product so that in case there are any edible plants around, these don’t get affected at all. This will make sure that the crabgrass is killed while the edibles stay as it is. 

Cold or Warm Climate

A very important factor is temperature. Temperature does control the crabgrass and therefore also the weed killer’s effectiveness. Crabgrass is most susceptible to these herbicides while they are in the active growth stage. The seed of crabgrass germinates when the soil has reached a temperature of about 55 degrees and the season is spring. During the summer season, the plant is matured and also produces seeds till the winter weather arrives. 

When you are going for just one application of the crabgrass killer, it will be sufficient for eliminating any kind of crabgrass near areas with cold weather conditions. Then the warmer climate regions do need repeated applications in all growing seasons. This also requires spot treating for making sure that you have effective control over the crabgrass. 

See if the product is restricted

If you have been living in areas that are open or just in a big state, where there are open spaces, these products will be commonly seen. However, some of them can lead to allergic reactions in some people. So at times, these are banned in areas that are densely populated. Therefore before you think of buying crabgrass, you should be checking it specifically if it has been restricted in the area where you live. 

Crabgrass killer Brand

You should only be buying products that come from a reputed brand. There are many fake products in the market and this also makes it difficult to find one that’s of good quality. Therefore it’s recommended that you do your research well and go with reputed brands as these are more reliable. 

Extra Features

As we have already said earlier, a lot of the products available in the market will be offering you the capacity to kill several kinds of weeds. However, it’s not compulsory that you just focus on this. In case you have an issue with dandelion or crabgrass only, search for something versatile enough. 

Also, a good feature to see in the product is how weatherproof it is. Some products are rainproof for about 1 hour; it will make sure that the effectiveness of the product remains good during rains. There are certain parts of the world where rains are heavy even during summers, and this makes crabgrass prevention difficult.

Product Toxicity

Some crabgrass killers can be a bit toxic to other plants as well. So read the product label well. Also, make sure that the solution isn’t being used around children or pets. Also while you are spraying the product yourself, you mustn’t breathe it at any point. The good news is that crabgrass usually grows towards the lawn edges and therefore the spraying and removing process gets easier. If the product comes with a nozzle spray, the application becomes a lot safer. 


We are sure that you must have enjoyed reading the article. And if the answer is yes, you can consider any of the products mentioned in the analysis. Understand that taking care of your lawn is important. And when you have an understanding of the crabgrass killers, it will make sure that you have the right products for you.
