Weeds are nearly guaranteed in any garden. All that water and those nutrients are hard for them to pass up. You can’t blame them, but you don’t have to let them stay. Commercial weed killers are expensive and the harsh chemicals they use are not always your first choice. Here are eleven ways to kill weeds naturally that will save you some money and keep your garden chemical-free.

1. Starve Them of Sunlight

Plants need sunlight to photosynthesize and produce fuel. You can kill weeds in just a few days by starving them of sunlight by covering them with a newspapers or empty cans.


2. Boiling Water

Boiling water kills weeds by scalding them to death. Save water by recycling the leftover water from your cooking.

3. Alcohol

Spraying weeds with a 1–5 tablespoons and 4 cups of water mixture will poison them. Just be careful not to get it on other plants.

4. Shake Salt

The same salt you use on sidewalks and your driveway during winter also kills weeds. But be careful, it will also kill everything else. Sprinkle salt into crevices that don’t have any other plants in them.

5. Baking Soda

If your crevices do have plants you want to keep alive, but are also infested with weeds, you can use baking soda instead of shake salt. Apply it the same way, and you can also use it on individual weeds. Sprinkle 1 tablespoon of baking soda onto wet weeds and be sure to cover the whole plant.

6. Vinegar

Mix 1 part vinegar with 1 part water in a spray bottle and spray onto weeds. It works well on dandelions and your weeds will be dead in a few days.

7. Dish Soap

If you don’t like the smell of vinegar, use dish soap instead the same way you would vinegar.

8. Other Plants

Plants compete with each other for water and nutrients. By filling any empty space with more plants, there won’t be enough nutrients or space for weeds to come in.

9. Corn Meal Gluten

This method is good to prevent future weeds from growing, but not for killing current weeds. Sprinkle corn meal all over your garden, and as it breaks down, it becomes nitrogen to fertilize your soil.

10. DIY

Make your own weed killer cocktail with these natural ingredients: 1 gallon white vinegar, 1 tablespoon dish soap and 1 cup salt. Mix it all together and spray it on weeds for an effective but natural killer.

11. Weeding

You may not want to hear it, but it’s true. Getting down and dirty in the weeds is still one of the fastest and most effective way to eradicate them. For the best results, pull them when the ground is still damp so you get all the roots. If you need some help, use a trowel to make sure you get it all out.
