Best Time to Spray Weed and Grass Killer
If your garden or lawn has been overrun with weed invasions, you are likely trying to find the best product to use to kill them. However, the weed killer you choose is only part of the equation. You also have to determine when it is best to spray the product on the weeds.
There are two primary types of weed killers. These include pre- and post-emergence products. The pre-emergence items are designed to disrupt the lifecycle of the weed.
Often, it includes the ingredients benefin and dithiopyr. This prevents the seeds of the weeds from germinating. It is best to use this type of product in early spring and reapply it about eight weeks after the first spray.
Post-emergency herbicides often include glyphosate, which is a strong chemical and kills weeds on contact. It works by being absorbed into the tissues of the plant. Generally, you should spray it on young, new weeds.
You also have to focus on weather timing. All of the products we reviewed were rainproof in as little as 15 minutes or up to two hours. This means that you don’t have to necessarily wait for good weather.
Still, you want to make sure that you have more than enough time to spray the entire yard or area with the weeds. This can take an hour or more on its own. Then, you have to give the product enough time to work, set, and dry.
When focused on when to spray, it’s also important to think about the wind. If it is a very windy day, the spray is likely to coat things you don’t want it to cover. These can include your flowers, trees, and shrubs.
All of the products we reviewed are designed to start working immediately or within a few hours. You can see the total annihilation of your weeds and unwanted grasses between 12 and 24 hours after application. Therefore, you’re not going to have to wait days or weeks to see results.
How to Use Weed and Grass Killer?
The way to use weed and grass killer can vary, depending on whether you have chosen a ready-to-spray product or one that is concentrated. If yours is a ready-to-spray version, all you have to do is hook the sprayer to the container’s opening.
You may need to spray it a few times to prime it. Then, you spray it directly onto the leaves and roots of the weeds and grasses you want to kill. It’s best to be thorough and careful so that you don’t miss any weeds or kill plants you want to keep.
If you have purchased a concentrated version, you are going to need to dilute it. Read the instructions on the container to find out how much product to use and how much water. Then, make sure that you follow the direction to the letter.
Once it is mixed and ready to go, you need to put the liquid into a sprayer. Tank sprayers are often recommended. They often look like squares and stand upright, but they can be on wheels and be more rounded.
Generally, they feature a primer/pump at the top, as well as an elongated spray head. This allows for more precision. You can also use other sprayer types, as long as they are designed to hold chemicals.
If you choose an all-natural or organic weed killer, you should still make sure that the sprayer is suitable for weed killer products. Consider labeling it, as well, so that you don’t forget and use it as a water sprayer later.
With so many products listed, it can be tough to determine a winner. When we focused on the best weed and grass killer, we had a few things in mind. For example, we wanted a natural and organic product because people are likely to spray them around pets and children.
This narrowed down the search, but it wasn’t enough. Then, we looked at how soon it started working and how long it took to achieve full removal of the weeds.
With that in mind, we chose the Green Gobbler brand with its vinegar weed killer because it had everything we wanted and more.
