  • arrow-right
    Spread fast and grow faster than useful plants

    Produce numerous seeds
  • arrow-right

If your lawn is looking neglected because weeds have taken over and you can hardly see the beautiful grass you painstakingly planted then this is when to apply weed control to a lawn.

How Do I find the Best Commercial Weed Killer?

When you want to get rid of weeds quickly and permanently, you should not purchase a weed killer hastily. You should first take time to research and establish which one will give you value for your money. Here are the qualities that you should look for when buying a weed killer for your farm, garden or lawn:

  • User-Friendliness: The product you choose to buy should not stress you. It should be easy to prepare and use. It should have clear instructions.
  • Effectiveness: Before paying for any product, you should find out whether it is effective. There is no wisdom in spending your money on something that will not do the job that you intend it to do. What ingredients have been used to make it?

    Also, find out what people are saying about it in regards to its effectiveness. Too many complaints by past users should indicate that buying the product will be a waste of time and money and therefore you should steer clear of it.

  • Safety: Determine the safety of a weed killer before purchasing it. You have to ensure that you only buy safe products. Its ingredients should be irritant-free. Some weed killers are even eco-friendly, meaning they are much safer than chemical alternatives. 

Important Information About Weed Killers

For you to make the right decision when you are out shopping for weed killers, you need to know some basic information about them. Basically, there are two major types of weed killers; pre-emergent weed killers and post-emergent weed killers. The former prevents weeds from germinating while the latter eliminates weeds that have already germinated.

Weed killers work in different ways and can be defined in the following two categories depending on their way of functioning. These are:

  • Contact Weed Killers
  • Systemic Weed Killers

Contact Weed Killers

Contact weed killers deal with weeds that they comes into contact with. These weed killers are very common, and they show results in a matter of hours as the weeds start to wilt. 

Though they are fast, they only damage the part of the weed that is above the surface while the root system remains intact. This type of weed killer is effective for getting rid of annual weeds that spread through seeds. These weeds include nettle, crabgrass, and bindweed.

Systemic Weed Killers

On the other hand, systemic weed killers work in the exact opposite way as contact weed killers do. The product usually travels through the weed, percolates into the soil and destroys the root system. They make it difficult for the weed to grow and also prevent it from using sunlight to manufacture food. However, these weed killers take longer to show results, about three weeks.

These products are ideal for perennial weeds that multiply through roots and seeds because the weed killers will destroy even what is underground. Some of the weeds that require systemic weed killers include thistle, dandelion and poison ivy.

Some weed killers have both properties; hence, once you buy them, you will get to enjoy their combined benefits. This video will explain how to use a commercial weed killer

Sometimes, people categorize weed killers into selective and non-selective. Selective weed killers are the ones that only destroy weeds and leave the grass intact while the non-selective weed killers kill almost everything that they come into contact with such as flowers, vegetables, and grasses.

Some weed killers have the ability to remove weeds as well as feed the beneficial plants. They are popularly known as "weed-and-feed" liquid. They are quite useful because they not only help you get rid of the annoying weeds, but also assist you in taking care of the beneficial plants you want to protect and see them thrive. Liquid lawn weed-and-feed are some of the best weed killers to buy as you will be feeding two birds with one seed (yes, I evolved the saying).

Do take into account that it would be very wise to hire an expert to apply commercial-strength weed killers. A professional will own the right tools and know the right amount to use. It can also help you avoid accidents because some of these weed killers are quite toxic and require utmost care when applying. If this seems like a hassle to you, you can always opt for homemade weed killers. Some of the best homemade weed killers include cornmeal, mulch, and vinegar.

I hope that, with this info, you will know what type of weed killer to buy for your specific needs. For instance, selective weed killers are best for spraying on a lawn because your lawn will be left thriving while the weeds die out. A pre-emergent weed killer is preferred when you have areas where you do not want weeds to grow, such as edges, fences, paths and other hard landscape structures.

With that said, let's move on to the best commercial weed killer reviews of 2019!
