Buying Guide for the Best Weed Killer
There are some important things that you need to know before buying the best weed killer in 2020. If you don't have enough knowledge about the weed killers, then you must read our buying guide. This guide will help you save a lot of money by investing in the right natural and organic weed killer. So let's have a look at those essential factors.
Let us tell you that there are two types of weed killers. One is pre-emergent, and the other is a post-emergent weed killer.

- Post-emergent weed killers target weeds that already have sprouted above the soil.
This is the main factor to consider before buying the accurate weed killer for your soil.
Other than that, there are two ways in which most of the weed killers work.
Contact Weed Killers
As the name suggests, this weed killer kills only the plants with which it comes into contact with. Moreover, these are very common, as you'll see the results in a few hours only. Although, contact weed killers, is quicker than other types of weed killers. Also, they will destroy the part of the plant above the soil. So if you are applying this type of weed killer, you need to be careful.
Generally, weed killers are great for dealing with annual weeds, which spread through seeds. You want to know why? Because the seeds are above the soil, meaning that you can directly spray on that area.
Other than that, common annual weeds include the bindweed, crabgrass, mallow, and nettle. So these all weeds can vanish easily via contact weed killer.
Systemic Weed Killers
Now comes those systemic weed killers. They work by absorbing the foliage and then travel through the weed to the root system. As they prevent the weed from growing and inhibiting its ability to produce food from the sunlight. Although: this weed killer is slower than the contact weed killer. But it can give the best results from 1 to 3 weeks.
Similarly, this weed killer is good for perennial weeds that spread through roots and seeds. As this herbicide will kill the weed below the soil. For example, common perennial weeds are bindweed, ragweed, poison ivy, and dandelion.
Other than these two categories of weed killers, some of the weed killers are systemic and contact. It is the best category of weed killers because it works with both of the functions in one product.
Also, you will hear selective and non-selective weed killers, so let us give some brief information about them too.
Selective Weed Killer

And selective weed killers are perfect for the established lawns. Further, you shall ensure to read the labels carefully before applying a selective herbicide. Because some of the selective herbicides destroy grasses such as St. Augustine grass.
Non-Selective Weed Killer
On the other hand, non-selective weed killers will kill everything that it touches. For example, it will destroy the grass, flowers, and vegetables. So you need to be careful while applying non-selective weed killers. Also, you may read the instruction to prevent any mistakes.
Combining It Altogether!
Some scenarios may suit one weed killer over the other.
So if your lawn is completely out of control! And you want to get rid of everything, and you should consider NON-SELECTIVE weed killer. But if you have weeds growing among the vegetables and flowers, then you must consider SELECTIVE weed killer. Plus, it won't damage flowers and vegetables. Consequently, non-selective weed killers are best because they don't harm the grass. And they are pretty easy to apply.
For having the best results, make sure to follow the instructions carefully. If you use the weed killers incorrectly, it can spell disaster!
