Sounds pretty good. Even the four landscapers I contacted for suggestions to remove four hundred square feet of weeds suggested using Roundup. They said the product broke down quickly, so I could plant new grass ten days later.
Vinegar is an organic solution for getting rid of unwanted vegetation, but I was concerned that it would leave the soil’s pH too acidic for grass to grow. And Roundup seems pretty innocent according to the experts in my area and, of course, according to Monsanto. Then again, anything Monsanto says is worth looking into—to be fair, anything touted as truth from all sources is worth investigation.
Roundup
The main ingredients found in the herbicide Roundup are as follows:
- · Water
- · Glyphosate
- · Ethoxylated Tallow Amine Surfactant
Water is used to dilute the glyphosate—the substance responsible for killing the unwanted vegetation.
Glyphosate is a toxic substance, but according to several studies, only slightly. I was surprised to find research claiming glyphosate wasn’t all that bad. Sure it irritates the eyes, but it “produced no visible skin changes or sensitization” during human patch tests. And tests for chronic toxicity, such as nerve damage, blood chemistry changes, cellular harm, or organ dysfunction, found no negative impact from glyphosate.
This got me thinking, Roundup may have gotten some unwarranted bad press. That’s when I explored the surfactant being used and found the combination of both the glyphosate and the tallow amine surfactant causes more damage.
Upon further digging, I located recent research that directly contradicted previous studies. The latest news is that “Glyphosate is likely to be pervasive in our food supply, and, contrary to being essentially nontoxic, it may in fact be the most biologically disruptive chemical in our environment.”
One thing is for certain: this is a heated issue with science claiming to back both sides. With so much uncertainty, it’s worth taking a look at an organic route: vinegar.
Vinegar
Full strength vinegar pulls water from plants causing the leaves to shrivel up and die. But this organic gardening technique is not selective; it, like Roundup, can damage grass and flowers, along with the weeds. Unlike Roundup, vinegar affects the surface and doesn’t soak into the roots.
Due to vinegar’s acidic quality it may be used to condition an overly alkaline soil. Some organic gardeners apply a highly diluted solution to alter soil pH. The change, however, is only temporary.
Even with full-strength vinegar, the acid affects the soil for only a few days, making it possible to replant less than a week later. If you’re still hesitant, like me, just water the area thoroughly after the weeds have died back and then replant. This way any residual vinegar will be so diluted it won’t impact the soil pH.
Conclusion
If you’re looking for an environmentally friendly choice, vinegar is the way to go. It doesn’t, however, tackle the roots. Older plants may wither on the surface initially, only to re-sprout a week later.
Roundup works on the roots and kills the entire plant, but there are potential environmental and health concerns with this product.
You could take the approach of using vinegar on younger plants and reserve a stronger herbicide for tough jobs.
Ideally, we can tackle weeds while they’re young or learn to love them!
