You want your landscape to look lush and beautiful, but you don’t want to use harsh chemicals that may harm the environment. The good news? You may already have the solution in your home.

Here are some natural weed-killers:

If you only have a few weeds, try pouring boiling water over them. A mixture of one cup salt and two cups boiling water can also do the trick on tougher weeds.

Vinegar is an effective weed-killer. Heat it slightly before spraying onto weeds to make it work even better.

Sprinkle baking soda on your sidewalks and driveway, and then sweep into the cracks to prevent weeds from growing.

The solution that does it all, WD-40 also kills weeds.

To make sure you don’t kill nearby plants when spraying weeds in a garden, try this tip. Cut off the bottom half of a plastic 2-liter bottle and place the top half over the weed. Then spray directly into the opening on the top of the bottle.

Finally, weeds often prefer acidic soil. To keep dandelions from taking root, improve the quality of your soil with compost and mulch.
