Easy Homemade Weed Killer Recipe

Hey!  I’ve got an easy homemade weed killer recipe for you today!

Weed killer is one of those things that makes me feel a bit uneasy.  I don’t like to keep it in the house, and I don’t like to use it in the garden.  I’ve recently come up with my own eco-friendly homemade weed killer to tackle the persistent weeds that blight our yard, but is gentle on the wildlife that frequent it (like this little guy).

I mentioned the other week that I’ve been trying to turn our unloved yard into a cared for space that we enjoying using.  Along with a good clear out, a lick of paint, a few plants and hanging baskets, and this homemade weed killer recipe, I feel like I’m slowly getting somewhere with the yard.

This wildlife friendly weed killer contains just three common household ingredients that you’ll probably have to hand – white vinegar, salt and washing up liquid.  The vinegar and salt help to dry out the weeds, and the washing up liquid ensures the salty vinegar solution sticks to the leaves of the weed.

See the results for yourself!

Homemade Weed Killer Recipe

You Will Need:

1 litre white vinegar

3 large spoons of salt

3 large spoons of  washing up liquid / dish soap (Don’t worry if it’s a more environmentally friendly brand – I used Ecover and it did the job)

Spray bottle


Add your salt to your vinegar and stir until dissolved.

Once the salt is dissolved add your washing up liquid, and stir well.

To Use:

This homemade weed killer recipe works best on a sunny day.  I’d suggest applying at midday, or just before, when the sun is at it’s peak.

The weed killer works indiscriminately on all plant life, and can turn your soil acidic.  For this reason it’s best used to kill weeds that have appeared in the gaps between paving slabs or mono blocks, rather than to tackle the weeds in your lawn or flower bed.

For small weeds and younger dandelions spray the solution directly on to the leaves.

For larger, more well established weeds spray the leaves and also pour a good glug on to the plant.  It’s very effective – you should notice the weeds beginning to wilt within an hour.

This homemade weedkiller recipe probably won’t kill dandelion roots, but it’s a quick, easy and green way to deal with dandelions and other weeds as soon as they appear.

  1. I have found a quarter teaspoon of salt in the centre of a dandelion or similar rosetted weed will kill it root and all. It is best done when there will be no rain for 24 hours. Don’t get salt on other plants as it will kill these as well.

  2. Yes! Vingear is great. I’ve also had great luck with simple boiling water – it’s perfect for cracks between concrete, too. Same results and easy-peasy. :)

  3. You know, dandelion leaves are actually edible. Pick the leaves before the plant flowers and they make a lovely addition to salads. They also have a whole host of health benefits. Perhaps you could change the way you look at these plants- instead of persistent weeds, you could see them as bonus veges that have popped up in your yard. There’s nothing better than free vegetables that take no effort on your part!

  4. How does this solution affect the insects, does it kill them too ??? I don’t want to eradicate them as well. Cheers.

  5. Please don’t use BOILING WATER, it’ll kill every insect anywhere near which defeats the object of an eco-friendly weedkiller.

  6. Can i just ask about the products like vinegar. Are we using a product that is sustainable to produce? In using more natural products are we burdening the producers and the land.
    I know the whole subject is awash with complications but it is worth considering as we change are ways.

  7. It’s so good to consider alternatives to chemicals and I thankyou for your contributions towards a more considerate world. Ultimately I think the only way to get rid of weeds is a good tool to fit the dig with good old elbow grease. This way there is minimal harm and more benefited eg upper limb strength and no weeds. Also Dandelions are bee-friendly as well as make good tea and salad.
