Weeds are the perennial enemy of gardeners, whether they appear on your lawn, in a flower bed, in gravel areas, or the spaces between pavers in paved pathways.
They compete with desirable plants for sunlight, water, and nutrients, and they look messy in the yard and walkway. Certain types of weeds can even proliferate to the extent of upsetting natural environments.
By suppressing the invaders, weed killers can prevent them from taking over the garden, lawn, and surrounding area.
However, eliminating weeds need not be bad for the ecosystem. Many potent herbicides that are easy to use, inexpensive, and very effective for home use have been developed by generations of chemical researchers. Keep reading to know more.

How to Apply Weed Killer
The wrong application can lead to complications and render your efforts ineffective even if you choose the correct weed killer.
A lot of weed killers require diluting with water before placing them in a spray bottle. The amount of water and weed killer you need to mix will be specified on the product’s label.
On the other hand, some weed killers are granular. Spreaders are required for applying solid weed killers.
When using herbicide, timing is crucial. Weed killer should not be applied right away after lawn mowing because it may damage your delicate grass. This also applies to fertilizer. Wait a few days before using weed killer in both situations.
Before we go, it is important to know if you apply weed killer too soon before it rains, it may wash away before it has a chance to become absorbed, and applying it too hot can cause stress to your grass.
