Best Crabgrass Killers – Buyer’s Guide
Have you ever used a weed killer before? If so, how familiar are you with general landscaping? Before you set off in your lawn and spray the crabgrass killers reviewed above, you should definitely do your homework.
To help you get started and end the weeding process on an outstanding note, read the following information below. By the time you’re done, you should also have a better idea on which products you think will perform best on your lawn.
The first step to getting rid of the crabgrasses in your lawn is to properly identify them. There are some grasses that resemble the weed at first glance, which is a common mistake that can be made that could end up with you missing spots during your spray. Crabgrass has a spade-like tip near the leafy portions of the weed, which grows at a horizontal angle that’s perpendicular to the ground.
In other words, sideways. If left untreated for a while, the stems will be easier to see. The stems will also meet up at the tip of the roots, close to where the undergrowth begins. If your lawn is mostly filled with ordinary grasses, they should be fairly easy to spot, since the weed hardly ever points in the same direction as the former.
Treating Your Lawn without Destroying It
Weed killers once had a reputation for being strong, yet destructive. Some formulas are mixed with ingredients that will virtually eliminate everything that it touches, while others rely on more natural killing methods. A good weed killer will eat away what you don’t want while preserving all seasonal growth.
When to Use Crabgrass Killers
Grasses are typically classified into three categories, which are annual, bi-annual, and yearly. Out of the three, the grasses that you would like to remain in your lawn should last through the entire year without dying off. They are also referred to as perennial. The other categories contain that weeds that you want to get rid of.
The key is to find the weed killer that will allow your perennial growth to remain in the ground without sacrificing it during your weeding. As such, you should use crabgrass killers the most when you see them growing immediately before springtime. April and May are the best times of the year to spray. Although the products above will work through each season, taking care of things before the ground temperature rises above 55 degrees (Fahrenheit) would be highly beneficial for preventing later weed growth.
How to Know When It’s Working
Crabgrass weed killers are a little odd in some ways. This is due to the varied length of time that some products will take before results are seen. With most, you should see the weeds dying within a two week period at the most. But others may take a little bit longer, such as four to five weeks. Still, there are a few that can work faster. After you’re done spraying, wait a day or two and observe your problem spots.
If you notice small strips of violet to purple-striped spots on the stems of the crabgrass, then your product is performing well. But regardless of the brand you do choose, heavily weeded spots might be better if you simply dig the weeds up from the ground, then re-seed. You might need to spray more than once a day with some products, but this is usually specified in the instructions when recommended.
Spraying in Wet Weather
With a low-quality weed killer, rainwater will quickly soak up the solution and render it useless. This may also negatively impact your perennial grasses. To help you avoid this problem, most of the weed killer evaluated above have a common feature. They stick to whatever it touches, which means you won’t have to worry about the chemicals going deeper into the soil, or running off the crabgrass.
However, you shouldn’t spray right before or during a rainstorm, so be patient and wait for things to dry up a little if you live in a region that receives a good amount of precipitation. If it’s still cold in your area, the low temperatures can actually help with your weeding. It’s a good time to get started before things heat up later.
Length of Time Until Results
For crabgrass killers, you might end up waiting a few days to a few weeks before the weeds begin to die off. But don’t panic if you haven’t seen anything keel over after a few weeks. If you need something that won’t take too long, brands with stronger formulas are good, or those that contain more solution.
More weed killer equals a higher amount that you can mix with water. Just be careful not to overdo it. And as mentioned previously, hitting the right season is key. Try to get things started before it gets toasty outside, and you’ll have fewer issues to deal with for the rest of the year.
Weed killers can be toxic to certain plants. But on a good note, most crabgrass killers won’t harm any of your other grasses. This could include some other weed species though, which might need to be treated with an alternative. Don’t use the solution around pets or small children, and avoid areas near gardens.
Most crabgrass grows on the edges of lawns, which makes it easy to spray and remove without getting exposed to other animals. Additionally, don’t breathe in the solution while you spray. This can happen if you’re not careful, particularly when used with a spray nozzle. The process is pretty easy, and most brands have comprehensive directions that’ll help this remain a non-issue.
