Although you can use some home remedies such as vinegar to kill the stubborn weed, the major downside of having quackgrass grow in your lawn is that it is very difficult to eliminate. As difficult as it may be, getting rid of it is not impossible.
Does vinegar kill quackgrass weed?Vinegar can get rid of crabgrass. A strong solution of vinegar, when mixed with orange oil, can kill weeds for good. However, this process has to be done in the correct manner lest the weeds sprout forth again. Most vinegar solutions are not effective in killing weeds because they are not appropriately prepared. While most blogs will give tutorials on how to make a vinegar weed killer, most of the content is laced with faulty information that does not yield any desirable result. This is because most of these tutorials only show vinegar with an acidity of 5% which does not help significantly. Household vinegar rarely kills weeds, though it may cause some of the weeds to shrivel and wilt a bit but not to die off completely. Noxious, hardcore weeds will need stronger agents for their complete eradication. To ensure that you achieve better results with your vinegar solution, you need to get vinegar with an acidity of at least 10%.
You should, however, be careful when handling vinegar with more than 10 percent acidity because it is very potent and dangerously corrosive. It can burn your skin and cause very painful wounds.
To keep yourself safe, wear goggles, long sleeves, rubber gloves and shoes when you are working with 10% to 20-% vinegar solutions. It is also important to apply vinegar mixed with orange oil.
How to use vinegar to get rid of quackgrassGenerally, the correct ratio for killing weeds with vinegar is 1 gallon of 10%-20% vinegar to one cup of orange oil.
Steps to follow:
Mix the combination well before applying it. If you have more weeds to take care of, use a type of sprayer that will cover a wide area.
This combination works best when applied at full strength in sunlight as the day gets heated up. To maintain its potency, you should not apply vinegar weed killer less than 24 hours after rains or when the forecast indicates an impending rain within the next 24 hours.This means that if the rains fell yesterday, you won’t be doing much if you apply the weed killer today. The optimum working conditions and maximum efficacy for vinegar weed killer averages at 70 degrees Fahrenheit.
Is it safe to apply vinegar on your lawn?The major downside of this brew of vinegar and orange oil is that it is not discriminative. It kills anything in its path. Therefore, you should be really careful when applying it to your lawn lest the entire lawn dries up. It kills plants, flowers, and grass just as effectively as it kills weeds. The best strategy to keep your flowers, plants, and grasses safe is by avoiding the use of vinegar weed killer on windy days. You can also use a paintbrush as an alternative for spray can to selectively eliminate quackgrass amidst other grasses in the lawn.
