9 Natural Weed Killers That Won’t Murder Flowers

Sea salt and water on weeds.

Finally, it’s time to trash the tarps and bust out your gardening supplies once again! Spring has (just about) sprung and everyone with a green thumb is undoubtedly ready to get back to it. But while gardening comes with many wonderful, relaxing benefits, it isn’t without some annoying aspects, too. For instance, finding a way to destroy weeds without killing your beautiful flowers in the process.

Your best bet for eliminating weeds and not your blooms are all-natural solutions. These nine weed-killing alternatives are professional gardener-approved and are made with products you might have in your cabinets at this exact moment. Check out these all-natural solutions to pesky garden weeds.

1. White Vinegar

One quick way to get rid of weeds? Pouring or spraying a little white vinegar on the offending weeds. This acidic masterpiece is perfect for shriveling weeds, just be careful of your flowers. A little excess spray won’t hurt them, but accidentally pouring the same amount of vinegar on your flowers as your weeds could kill them.

2. Cornmeal

Want to stop weeds before they even start? The proteins in cornmeal – or specially-processed corn gluten meal – stop any seed from germinating and growing. You can also sprinkle cornmeal on grown weeds, it’ll kill them just as well as it’ll stop them from growing.

3. Newspaper

This technique is called “smothering”, and it’s the process of literally weighing down weeds so they have no light, air, or room to grow. Wet some of those grocery store fliers and lay them on top of your weeds. You’ll get rid of your junk mail AND destroy gardens weeds, all at once!

4. Boiling Water

Perhaps the easiest and cheapest method on this list, using boiling water. Heat up a kettle of water and (carefully!) pour it directly on your weeds for a quick, chemical-free way to purge your garden.

5. Borax

You might not have thought of using this kitchen must-have in your garden, but it’s very helpful for killing unwanted weeds. All you have to do is add 10 ounces to 2 ½ gallons of water, mix thoroughly, and spray onto the weeds thoroughly. Watching them wither away smugly, optional.

6. Homemade Herbicide

Store-bought herbicides have been killing weeds since they were mass-produced in the 1970s, but the insane amount of chemicals found in most of these products is a big turn off for some gardeners. A great option is to make your own homemade herbicide! Just as effective with little to no chemicals involved.

In a bucket, combine equal parts vinegar, table salt, and dish soap for a weed killing solution that can’t be stopped. Put it in a cheap spray bottle for easy use.

7. Mulch

The most common way to smother is to lay down a nice layer of mulch in your garden. Although mulch won’t hurt the plants you love and tend to, it will cover and kill the lower weeds. Best of all, the thick layer of mulch hides the weeds even after they’re dead, something that can really ruin the aesthetic of a garden.

8. Baking Soda

You can apply baking soda to unwanted weeds any time of the year at the rate of 1 teaspoon per weed plant. The baking soda must coat the entire plant, including its foliage, with the bulk of the baking soda covering the weed’s stem. This technique works best on patios, walkways, and driveways.

It can also be used as a preventative measure by sweeping baking soda into the cracks (or sprinkling it onto the areas) in which weeds grow.

9. Table Salt

One of the most popular methods for killing weeds and saving plants is table salt. You can sprinkle salt directly on the weeds or even create a salt water mixture to be sprayed, which will help assure that your garden plants are safe. To make sure your other flowers don’t get hurt with this method, make sure to sprinkle a little salt at the base of each weed.
