#Organic weed killer –

We have briefly discussed weeds in the paragraphs above and have stated ways to kill them. Some of the best weed killers are given above, but you might have noticed that most of them are chemical-based weed killers?

Chemical weed killers are indeed more potent than organic ones, but they do have a drawback too. Chemical-based weed killers might also affect the other desirable plants in your garden or lawn.

Harmful effects of chemical weed killers –

Buying chemical-based weed killers are indeed one of the fastest and best ways to get rid of weeds from your garden. But, of course, you might always want to rush to your closest gardening store and buy a bag of chemical-based weed killers.

These chemical-based weed killers are decisive and helpful, too, but generally, these are used by farmers or large plantation owners who need to maintain weed-free soil on a massive scale.

People in suburban areas who just want to get rid of weeds from their lawn, vegetable garden, or walkways and driveways don’t always need chemical weed killers. This is because chemical weed killers are hazardous to other plants and humans, and animals.

Considering this, there is undoubtedly a natural and organic way to get rid of weeds without using any chemicals and affecting the ecosystem of your soil and surroundings.

Prevent weeds from growing –

You may use chemical-based weed killers or organic weed killers, but the best way to get rid of weeds is not to let them grow in the first place. The best time to do so is just before planting your lawn or garden. This can be easily achieved by following these steps –

  1. Remove all the vegetation with the help of mechanical or handheld tools from the area where you want to plant your lawn.
  2. Cover the whole area with a transparent plastic sheet and leave it as it is for a few days under the sun.
  3. During this period, the sun will burn any remaining vegetation and dormant seeds present in the soil and make the whole area completely lifeless.
  4. Once this process finishes, you will have an area that is 100% free from any kind of weeds or vegetation. You can then plant any plant you want to without the fear of being infested with weeds.

But if you already have a well-grown lawn infested with weeds and need care and weed removal, you can always go for natural weed killers.

Natural weed killers for gardens –

Just like chemical-based weed killers, many organic weed killers are available in the market too. Primarily such organic weed killers are based on the natural weed-killing properties of corn gluten and citrus.

If you care about your environment and want a chemical-free way to get rid of weeds, this natural weed killer for the garden is probably the best choice for you.

# BioSafe weed control concentrate

Pros –

  • Organic in nature.
  • Do not harm humans or animals.
  • Replantation can be done after four days.
  • Do not leave any residue.


Organic weed killers are all good for the environment and people, but they do have a drawback. They work slowly and are much costlier than their chemical counterparts. If you still want to kill the weeds without using chemicals and want to save some money in the process, you can always try making your natural solution for the weeds.

Making your organic weed killer –

Organic weed killers do not contain chemicals, but they have some natural elements that help them achieve the same result as one would expect from a chemical-based weed killer. Certain natural ingredients have weed-killing properties in them. Citrus-based natural products are a good example.

Such products work by altering the soil’s acidity around the weed’s roots, which deprives the weeds of much-required nutrition. This results in the slow death of the weeds. Products containing citrus are organic, and thus the acidity caused by them in the soil slowly vanishes over time, so the ground becomes available for plantation again.

You can create a natural weed killer for gardens at your home using natural ingredients that have herbicidal properties.

Vinegar –

  • One more such ingredient is Vinegar. Like citrus-based products, Vinegar also alters the acidity of the soil, making it a perfect natural weed killer.
  • Lawns having a high density of grass can also be treated with the high-strength vinegar solution, while for fragile properties, you may need to dilute the vinegar a bit.

Corn Gluten –

Corn gluten works similar to Vinegar and Citrus fruits by increasing the acidity of the soil. One thing that can be considered as a drawback with natural weed killers is that they need to be applied multiple times to kill the weeds completely.

Since organic weed killers are made of natural ingredients, there is no problem applying the herbicides multiple times. Also, Make sure that you use these natural herbicides directly to the roots of the weeds, as the better, they reach the origins of the weeds, the better chance they have of killing them.
