In some United States regions where it doesn't rain very much, an organic weed killer is incredibly essential. Using chemicals such as roundup to destroy weeds all year long creates a chemical build-up that continues to develop until a good rainstorm eventually hits. Then all the chemical build-up from every yard instantly drains on its way to the ocean into the sewage system. In regions with low rainfall, beaches and coastlines are frequently polluted for days once it eventually rains, and beachgoers are advised not to swim. It's unfortunate if you ask me because there might be a lot of runoff from the waste.
That's why I looked instead at an organic weed killer. In a low rainfall area, I helped run a landscaping business and continuously had to fight between being successful and being environmentally friendly. In the end, our clients appreciated the fact that we took a little extra time and energy to help protect and be vigilant about the environment. There are a few household organic compounds that act as organic weed killers well. The good thing about these chemicals is that they're also inexpensive in general.
The underlying theory of why organic liquid fertilizers operate is that they are almost always some acid type. As with common plants, weeds dislike acid, but the odd thing is that not all plants dislike acid soil. In an acidic climate, some plants grow very well, but most weeds don't. So, for you, there's a little trick. If you want to plant a garden but don't want to grow a host of weeds, plant a few acid-loving plants and hold your soil with items such as coffee grounds and garden sulfur more on the acidic side. Acidic soil is why under those varieties of pine trees, which drop their needles, you hardly ever see anything rising. Pine needles cause the soil to become acidic, and you have a powerful weed barrier. When you combine it with the overshadowing tree, it takes up much of the sunshine.
Even more, are there. Not only are the plants beautiful, but they also like the kind of soil that weeds usually do not like. That's why if you're thinking of trying to give organic weed killer a try, plant some plants that are also acid-loving so that they can benefit from the vinegar spray and not be affected by the rise in the pH of the soil. It's a situation of winning. If you want to try an organic weed killer, you will have to be very careful not to use too much of it. The spray can alter the pH temporarily and damage the usual plants if any of the vinegar is washed into the soil. This pH shift is only temporary for most organic weed killers, though, and in the one, we're going to discuss next.
Here's a short description of what to use, now that you know the pros and cons of organic pesticide and the right setting to use it in. The most effective natural herbicide that I've found is acetic acid. What are you talking about acetic acid? From vinegar and 5% of acetic acid is the household white vinegar you buy in the supermarket. It is good at destroying weeds on its own, but you might need something with a little more of a punch for real results. It will do a lot better job as a herbicide if you come across distilled white vinegar that's 15 percent or even 30 percent power. In shops that offer tons of horticulture products, you can usually find more potent distilled vinegar.
Only spray it right onto the leaves of the weed to use vinegar properly as a herbicide spray. Do not brush the other plants with vinegar, even acid-loving ones. Just slightly acidic soil is enjoyed by acid-loving plants, not acid on their leaves. The vinegar is strong enough to destroy all of the leaves or foliage it touches. Vinegar spray temporarily increases the soil's acidity and will keep it elevated for around a week or so. Distilled vinegar with extra strength does work wonders and is very biodegradable. The organic group recognizes it as a perfect herbicide in most forms. I claim "most forms" because the use of harmful chemicals is needed by some processes of making and distilling vinegar, so these forms will not be considered entirely organic.
