Updated on September 13, 2014

How to Make Homemade Weed Killers

Homemade weed killers are a cheap alternative to using store bought weed killers. Using homemade weedkillers is also safer for your family and pets.

You can make your own weed killers at home using everyday household items that you may have never known would work. Keep in mind that with any weed killer, these homemade weed killers will also kill grass and plants if it comes in contact with them. Be sure to apply them sunny days when the weather is calm.

Nearly every one of these weed killers are immediately safe for children and pets so there is no need to worry about harmful chemicals.

Lemon Juice As An Easy Homemade Weed Killer

When Life Gives You Lemons... Make a Weed Killer

Lemon juice can also be used as a homemade weed killer. Using store bought lemon juice or juice from fresh squeezed lemons, apply to weeds as needed. Lemon juice can be expensive but works well if you have old lemons or lemon juice about to expire. Use lemon juice at full strength.

Kill Weeds Using Salt

Salt is another 'homemade' weed killer. It can be applied using 1 part salt to 2 parts water or sprinkled directly on the plant. Keep in mind that high salt content can damage soil and should not be used around plants, trees or shrubs that you want to keep. It is best used around driveways, sidewalks, buildings and cracks.

Vinegar as a Homemade Weed Killer

Kill Weeds Using Vinegar

Vinegar is a homemade weed killer that is used for killing grass and weeds. It even kills dandelions! Spray solution directly on the weeds using a solution that is half water and half vinegar. Use spray bottle to apply the solution until they are covered thoroughly. Allow the weeds to dry and within a day or so you should notice the weeds dying off.

Some caution should be used when using vinegar as a homemade weed killer. Household vinegar contains 5% acid and pickling vinegar contains 9%. Such high acid rates can not only kill plants but also destroy beneficial organisms in the soil so avoid spraying the soil. Do not plant anything near the area anytime soon. < a href= "#" id="broken_link_47102297" style="color:#333; text-decoration:line-through" oncontextmenu="return showBrokenLink(47102297, false);" onclick="return showBrokenLink(47102297, false)">Image Source

Bleach as a Homemade Weed Killer?

Bleach Not Only Cleans Your Home But Also Your Flowerbeds

Yes, bleach can be used as a homemade weed killer and can be used on areas that will be planted in just a few days. Since bleach is evaporated by the sun the soil is safe for planting in a few days. Another advantage to using bleach is that if you get it on your plants you can quickly rinse it off without damaging the plant or the soil. Image Source

Kill Weeds with Boiling Water

Scald Weeds With Boiling Water

I'm not sure that boiling water is considered homemade but it can kill weeds. If you think a hot summer day can parch a plant you should see how fast boiling water can kill a weed…and any other vegetation as well. Just remember that anytime you are using hot water be sure to use caution so that you don't get burned. Use a safe kettle, pot or metal watering can. Do not use a plastic watering can as it can melt causing you to get burned. Image Source

Corn Gluten Meal as a Natural Weed and Feed

Weed and Feed with Corn Gluten mean

Corn Gluten Meal can be found at local feed and grain stores and work well as a natural weed killer. It doesn't actually kill weeds that are already growing but will kill weed seeds and prevent them from growing. It's the most natural weed pre-emergent you can buy.

Broadcast corn gluten meal during early spring, though out your garden and flower beds and anywhere else you want to prevent new weeds from popping up. It can be used during the growing season periodically to prevent new weeds from sprouting.

DO NOT broadcast corn gluten meal over a freshly planted garden or flowerbed that has been planted with seeds. Bulbs and other root plants are safe but and can be scattered with the corn gluten meal. Onions and some bulbs actually benefit from the nutrients found in the gluten meal.

      Useful information on killing weeds. I wouldn't use the boiling water though. I boiled a pan of water to take outside on my steps to kill ants and I dumped the boiling water on my leg accidentally. Ouch! Did that hurt. It looked really bad and I thought that I would have scars, but I lucked out. and didn't have any scars.

      Vinegar is effective on many types of weeds and grasses, especially when the weed is in direct sun. Spray on the vinegar, and the weeds start to shrivel in the sun.

      I just tried an experiment with salt and vinegar on two separate weeds to see which worked. It is thistle I am trying to kill. Horrible weed! Anyway they both dried up but it seemed the vinegar worked better. The weed with the salt had new sprouts emerge but the vinegar one did not. I will try some of these other solutions. Since, I have been trying to find something organic for my weeds which would not hurt my puppy. My other dog died of a heart tumor which may have been caused by pesticides used in lawns. :( I have stopped using them completely and now have dandelions which is okay to me. Since my puppy is healthy and happy. :) Great lens which I will reference a lot. Thanks!

      This is an awesome lens, thanks for writing it! I have not used any of these home-made weed killers, but like the salt, and boiling water ideas. I wonder if you can combine those two together? Also, do any of these weed killers keep the weeds from coming back (aside from the corn gluten one)? Our lawn is awful every year...first come dandelions, then those white, puffy weeds with all the seeds that blow around, and finally comes the white clover. They are all over the yard, and it drives me nuts waiting for them all to die off naturally. Although I don't think I should spray the whole yard with salt! I'll just use that along the edges and in the cracks.
