The Best and Safest Way to Kill Weeds


Unless you spray your lawn with chemical poison regularly, you will have to fight the battle of keeping weeds from your lawn.

If you have children and pets who play on the lawn, you may be looking for a safer way to keep weeds out of your lawn.

1. Douse them with hot water, salt and/or vinegar

Pouring boiling water on any plant will wilt it and it will kill some, but not all. Most weeds have deep, vigorous roots that will put out more shoots even if the plant looks dead. If you use just hot water, you will kill more grass than weeds.

Use vinegar full strength or make it stronger by boiling it down a little. Hot vinegar works better than cold. Pour it directly on the weed, being careful to not get it grass or other plants you want to keep. It might take more than one application, but vinegar will kill a lot of weeds.

Salt is the most dangerous to your lawn or garden because it will kill almost anything for quite some time. There are very few plants that thrive on salt water. Salt or salt water is best used in an area where you don’t want anything at all to grow, like paths or fence lines.

Be aware that you must stay a few inches away from the edge of the area so the salt won’t wash into the lawn or garden when it rains.

2. Dig and pull

The safest way possible is to dig and pull weeds. The hardest part is that it seems like a never ending task.

At times, the roots will break off at ground level or below the surface and regrow. Some weeds have very deep roots which make it almost impossible to destroy them. If you keep chopping, digging and pulling, even the most tenacious weeds will eventually have to give up.

This is a very labor intensive way to deal with weeds, but if you enjoy gardening and want something inexpensive, this is a good choice.

3. Smother

This, too, is for an area where you don’t want anything to grow. It won’t kill plants in the long term like salt does, but it will clear an area of weeds and grass.


Put a layer of newspaper, cardboard or something similar, over the area, then cover it with black plastic. Weigh this down with a few rocks or pieces of wood and leave it. A full season is best, but if you start early in the season, a couple of months can make a big difference.

Being deprived of sunlight and air and subjected to the extreme temperatures of sun on black plastic is what does it.
