Most weed killers out there contain glyphosate. Although the FDA considers the glyphosate as safe when used as directed, there’s a growing concern about the possible harm it can cause to the environment. If you’d like to try some safer alternatives, then below are a few of the many options.
An excellent alternative to a commercial weed killer if the weed problem is not too severe is a good old vinegar. However, your household vinegar isn’t usually enough to kill the tough types of weed. What you can do is add a bit of salt to increase its potency. Also, adding a drop of liquid soap allows it to the leaves and stems so that it won’t wash away easily.
If you want more potent, then you can try an industrial or horticultural vinegar. A lot of gardeners will swear by its effectiveness as it contains more acetic acid — around 20% – 30% more compared to the household vinegar.
Certain essential oils like citronella pine and peppermint can cause a burn to the weed’s foliage. However, it’s usually not enough to kill the roots. On the upside, it’s definitely safer compared to glyphosate.
If you have pets in the house, keep in mind that some types of essential oils can cause health problems. Hence, be sure to check if the essential oil you plan on using is safe for your specific pet.
Corn Gluten is a by-product when you process corn. It’s dry and powdery. It’s perfectly safe for the environment, pets, and humans. It does a terrific job of slowing down the growth of weeds. On the downside, it can’t do much for weeds that are already fully grown.
Although the commercial weed killer is excellent at killing weeds, still there is a sustainable weed control at Contact Organics and there is a growing concern about how it affects the environment. If you want to do your part in keeping the world a “greener” place, then you might want to try some safer alternatives like vinegar, essential oils or corn gluten.
