Homemade Weed Killers

Herbicides, also commonly known as weed killers, are used to kill unwanted plants. Selective herbicides are used in garden beds and lawns that kill specific unwanted plants (weeds), while leaving the desired plants unharmed. Non selective herbicides are used to kill all plants with which they come into contact to clear pathways and grounds.

We usually use glyphosate based herbicides like Roundup to get rid of weeds in pathways. I was looking for an organic, homemade weed and grass killer that is cheap and easy to apply.

My aim of looking for a homemade weed killer was not only for the high cost of Roundup, but a recent research has revealed that Roundup has potential of carcinogenic and tumor, skin cells even exposed to extremely low concentrations of this herbicide.

After trying a couple of easily available ingredients at home, now I don't need to resort to Roundup to keep my pathways and driveways clean.

You can make a number of environmental friendly, safe, cost-effective, less toxic, fast acting and easy-to-use homemade organic sprays using inexpensive ingredients you already have in your house.

There are several options that you can try to keep your garden and home clean this season. Some young weeds will die in a day while some weeds may need to be treated more than once.

So far I needed only one application to get rid of even the most harmful weeds like Dandelion.

No matter which homemade weed killer you use, always apply when the weather is warm, probably during mid day. No weed killer is suitable for all seasons. Spray on the weeds so that they are completely wet. The weed killers given below are non-selective so don't spray on grass and other plants.
