Using Natural and Organic Herbicides

Using Natural and Organic Herbicides Information

By Josie Borlongan, Garden Guides Contributor Chemical herbicides had been found to alter the soil compound and harm not only the weeds but the surrounding vegetations as well. Because of this and other negative effects of chemical herbicides and weed killers in our environment, researchers had been able to find ways and develop natural and organic herbicides that are more eco-friendly.

There are a few organically approved herbicides that are available in the market for farmers and gardeners. These include acetic acid (distilled vinegar), which can be used on its own or in combination with citric acid; products that contain clove oil, soap-based herbicides (non-detergent); some corn gluten meal products and hot or boiling water. These herbicides are reported to work best on young weeds and not as effective on established weeds.


Assorted natural or organic herbicides:
* Acetic Acid
* Soap-based herbicide
* Corn gluten meal herbicides
* Boiling water


* Use pre-emergent herbicides to attack annual weedy plants at the source which is while they are seeds. These herbicides act to inhibit seed germination before weeds have the chance to sprout. A good example of a pre-emergent herbicide that doesn't use any chemicals is corn gluten. Keep in mind that corn gluten will inhibit the seed of good crops or plants from germinating, too. Avoid using it in planting beds where you're starting plants from seed.
* Another type of organic herbicide is the post-emergent herbicide which is used only after the weeds have appeared on stage. A good example of this is using vinegar as the weed killer. If you only have young weeds to deal with in your planting bed, a common cooking or household vinegar can be used. The acetic acid in vinegar gives it the herbicidal abilities. When the percentage of acetic acid in the vinegar is high, it is more effective. If you are using culinary or cooking vinegar which is low (5 percent) in acetic acid try boiling it down to increase its strength. There are also buy super-strength vinegar available in stores that can be used for bigger areas.
* Practice caution when using vinegar as a herbicide, and apply it only directly onto weeds. Vinegar can negatively affect good crops or plants which will also die when exposed to this herbicide. This is why vinegar is not a good choice for battling lawn weeds because it will damage to your grass.
* Boil or hot water can be used to kill weeds by pouring them carefully dousing both the weeds and the soul immediately surrounding them.
* A strong dose of soap can kill weeds by burning their leaves and roots. Mix 5 tbsp. of natural liquid soap with 1 quart of water into a pump spray. Spray leaves and the root area of weeds during the hottest time of day. Check in 24 hours. The weed should appear burned and nearly dead. If not double the concentration and spray again. Different weeds require different strengths of soap. You will have to experiment to see how tough the weeds are.

These techniques can be used for a wide range of weeds.
