The following review will be useful if you seek natural weed killers that can cope with a weed problem without any chemical. After a few weeks of tests and consulting with professional gardeners, I’m ready to give a few tips for the buyers of environment-friendly weed killers.
How to pick natural weed killers in the U.S. market?
For instance, you may opt for harmless herbicides for both humans and soil – the use of a concentrated solution of ammonium nitrate: 6.5 lbs. of ammonium nitrate per 2.6 gallons of water. Such concentration will burn any weed. Most of the nitrates will be weathered into the atmosphere as ammonia in 2 days. Only a good fertilizer for useful plants will remain in the soil. The manufacturers of natural weed killers also use kerosene and solarium. But such solutions can only be used where the vegetation is not needed at all and you are going to grow nothing in the next few years.
Keep in mind that natural herbicides have disadvantages. Thus, they have no selective effect – they can destroy all the vegetation without distinguishing between useful crops and weeds, so their use in parks, gardens or beds is not appropriate.
At the same time, organic leftovers are rapidly destroyed without leaving any residual compounds, so such herbicides are good for use during the preparatory pre-seeding work for the complete weed control of areas. Organic herbicides are products based on fatty acids that kill weed crops, acetic acid (grape vinegar), essential oils (eugenol, clove oil, citrus oil, etc.).
A simple recipe for DIY natural weed killer
Weeds can be sprayed with 6% vinegar (4-5 glasses) in 0.5 gallons of water before sprouting. This solution is enough for a couple of acres. Try not to get it on vegetables and flowers – it will burn. It is harmless for the soil – this amount is not enough to change the acidity of the soil, and on southern, carbonate soils, even useful.
Of course, it doesn’t kill rhizomes. But it will allow vegetables to climb before the weeds are burned. And then you can walk with a hoe. Spray vinegar’s weeds behind the fence or on paths every 2-3 weeks, you get rid of the need to pull them, and the weeds like rhizomes will eventually die.
You can also add cooking salt to the vinegar. It is better to use this mix behind the fence or on driveways. But if the spring was late and saw thick thickets on the website, the vinegar-and-salt solution will not be superfluous. It burns out all unnecessary vegetation effectively and forever. But it’s the cheapest way.
