Make Your Own Weed Killer

Pesticides used to control lawn weeds are being banned in Canada. Ontario has already banned the sale and use of any pesticides that contain 2,4-D, diazinon and amitrole with more provinces set to follow.

Pesticides are also expensive costing around $15 per application. There are alternatives to using commercial pesticides.

  • Weeds such as dandelions are especially hard to get rid of. On a dry day simply sprinkle salt right in the center of the plant. In a few days the plant will have shriveled up and died. You will be left with a small brown patch but this will return to normal in no time at all.

  • Spray vinegar directly onto weeds. Be careful not to spray on other plants as they too will die. As before do this on a dry day.

  • For extra strength you can also add some orange oil extract to the vinegar.
Stores are selling organic or environmentally friendly pesticides alternatives which is basically concentrated vinegar. At Home Depot at 4L jug costs $16 the same 4L jug of pickle vinegar at No Frills costs $5.

    So seawater will also do the trick?

    Seawater or salt water will kill the weeds but it will also kill all of your grass.

    Once salt gets in the soil it will take years to wash out. Meanwhile nothing will grow.

    Boiling White Vinegar! I tried everything on nutsedge, but because its root is a nodular tuber, they kept coming back - and spreading.

    I had heard about white vinegar, and I heard boiling water, so I thought: Aha! Boiling White Vinegar! (Great name for a rock band.) Filled the teakettle, waited for the whistle, got an oven mitt, and went to town. It was so satisfying - even better when husband expressed his amazement that they were gone - permanently! I use this trick now between flagstones, etc. - anywhere focused weed killing is in order.
