What Are Crabgrasses?

Crabgrasses are one of the peskiest type of grass that you don’t want to encounter in your lawn or garden. It features finger-like leaves that are long and dark green in color. These grasses grow in bunches over the soil in your lawns and have roots that can be very difficult to pull out since they are buried inches within the soil.

It is a tropical type of grass which grows in warm regions and is considered as weed because of its ability to grow and multiply at an alarming rate. During summer, it dies out and can become very unsightly in a garden.

It’s an annual plant and it flourishes only for a couple of months but the effect that it leaves on the garden’s aesthetics as well to the soil can be quite alarming and can last a whole a year. This is the reason why garden owners deal with the problem of crabgrasses at the first signs of it.

Considerations To Make When Purchasing The Crabgrass Killers

Weeds are a persistent foe in the garden. Whatever you do to kill them, they always keep coming back. While there is still no definite way to eliminate the problem of weeds in the garden permanently, there are surely a few ways on how you can keep them from coming back any time soon.

To ensure that they don’t come back right away, we use crabgrass killers. This solution is proven and tested to deliver the weed extermination that you need for your garden.

Finding one that suits your needs however can be quite a challenge since there are lot of crabgrass killers in the market to choose from. So, to help you with that, we’ve came with a few considerations to make.

These considerations will help you make a better decision on the best option that matches your requirements and your budget.

1. Pre-Emergent And Post Emergent Herbicides

Crabgrass killers will be mostly about herbicides and there are a lot of herbicide varieties to choose from. The first variety is the emergent herbicides which are covered by pre and post emergent herbicides.

The pre-emergent herbicide functions by blocking the enzymes in a grass in its seed germination. This results in stopping the grass or weed from growing. This can only be an effective herbicide to use when applied during summer or when the temperatures are high.

The post-emergent herbicide on the other hand is used after the weed has already grown and flourished in the garden. This type of crabgrass solution could be a good choice after using the pre-emergent herbicide and still left with a few stubborn weeds.

Although the latter herbicide is not very effective against thick and established crabgrasses, it can be used for the rest of the seasons for longer effect.

2. Contact And Systemic Herbicide

Contact herbicides are all about poising the plant when they contact each other. As soon as the plant contacts another, it breaks down the photosynthesis process as well as chlorophyll which starves the plant and causes it to die.

Furthermore, it causes abnormal growth as well as unproportioned distribution of nutrients in its system causing it to strangle itself. If you’re looking for a quick herbicide then you can choose contact herbicides.

Systematic herbicides on the other hand is the method that takes more time among the two. However, although doesn’t work as quickly as contact herbicides it leaves a lasting effect on the plants.

3. Selective And Non-Selective Herbicides

Selective herbicides as its name suggest are specific types of herbicides that only work on eliminating selected plants. This is an excellent solution especially if you’re only looking to eliminate grass around a flower or a plant.

Non-selective herbicides on the other hand is the general kind of grass or plant killer which kills almost any kind of plants. This is a rather risky herbicide to choose since it can kill all nearby plants and vegetation in a garden or lawn. The non-selective herbicide would be an excellent option if you’re looking to work your garden from scratch.

4. Environment-Friendly Options

You can choose from an organic crabgrass killer and the natural crabgrass killer. While both options are environment-friendly and doesn’t use chemicals, they can use other non-natural tools and accessories to be effective.

One of which is the black plastic mulch with organic crabgrass killers use – these are non-natural and may leave less-impressive results than natural crabgrass killers.

5. Safety Measures

  • A specific mix and measurement of ingredients prior to use
  • Product expiration and where to store the product
  • Proper use and maintenance

I appreciate the insight of this article. However I don’t see how you can rate the Scotts the best since you have to till the topsoil to get the best seepage. I don’t want to destroy my grass as I’m trying to get rid of the weeds.
