Ask a gardener of any skill level what the hardest part of having a garden is and they will all tell you the same thing – getting rid of weeds.

Invasive plants are everywhere and it’s no wonder why we have so many commercial weed killers on the market.

However, synthetic pesticides pose a threat to children and pets if swallowed.

Fortunately, there’s quite a lot of ways to get rid of weeds naturally. Some of these eco-friendly methods include…

Weeding By Hand

Weeding Hands

This is the most basic and easy way to dispose of the pesky plants growing in your garden.

Use a handy tool, such as a claw or trowel, to loosen the weed roots.

After that, pull the weed by the root.

Use gloves to avoid spreading seeds anywhere else.

Boiling Hot Water

Boiling Hot Water

Prepare a kettle of hot water and take it to your garden.

Make sure you aim around the crown of the undesired plant.

For some plant sorts it might take several tries, but it will kill them eventually and your garden will be once again weed-free.

This method is also good for spots you plan to replant, because it won’t damage the soil.


Cup of salt

Pure salt dehydrates plant leaves and sabotages the proper moisture intake of the weed’s root system.

You can mix it up with some water to make a potent solution.

Utilise this method carefully as water and salt solutions can be deadly for regular plants as much as for weeds.

It’s best to use it in small amounts as otherwise salt may permanently damage your soil.



Pure vinegar (white or cider), just like salt, causes dehydration to unwanted plants.

It also evaporates quickly after use, however you need to be very careful when using vinegar as it kills any plant it comes in contact with.

Luckily, you can find many useful recipes on what ingredients to mix with vinegar so it’s not as strong.


Mulch Wood Chips

Cover the soil with grass clippings, wood chips, sawdust, shredded bark, and other organic materials to stop sunlight from reaching the soil.

This, in turn, should kill the unwelcome plants.

Mulch also prevents new weed seeds from entering the soil.


Stack of Newspapers

Newspapers quickly go out of date, but fortunately they can still serve your garden well.

Use old newspapers to cover low-growing plants.

Make the cover at least four layers thick.

Eventually, the lack of sunlight will be the demise of your weeds and will stop weed seeds from developing.


Glass of Vodka

Mix this strong alcohol with some water and put your new organic herbicide in a spray bottle.

The vodka to water ratio depends on how stubborn your undesired plants are.

Spray the nasty weeds and watch as they dry out.

Be advised – this method works best on sun-loving invasive plants.

If you are dealing with another weed variety which you can’t recognise, you might want to book professional weed removal services instead.


Shirts Washed With Bleach

To get rid of weeds naturally with bleach, pour some of it on the pesky weeds growing between the cracks of your walkways.

In a couple of days, you should be able to remove the plants easily.

The bleach will also keep them from coming back.



A propane torch is probably the best natural herbicide you can get.

Do be careful with this method though as you don’t want to burn your “good” plants in the process.

Not really a weed killing method, but rather a weed prevention one.

No seeds will grow into plants when sprinkled with this meal ground.

Carpet Scraps

Rolled Carpet

Got an old carpet you no longer need?

Cut it up into scraps and use them as a weed barrier.

The old carpet pieces will stop invasive plants from growing and still allow water to drain.

Keep in mind that the scraps should not remain on the soil for more than a year.

Ground Cover Plants

Ground Cover Moss

Ground cover plants are great when you need to cover bare patches of soil and, wouldn’t you know it, they also compete with weeds.

In fact, they are so competitive that they will deprive the weeds from their much needed nutrients, water, and sunlight.

For more information on ground cover plant types, go to RHS.


Salad in Plate

Weeds are, after all, plants and some of them are perfectly edible. Some examples of weeds you can prepare for dinner include: curly dock, wild amaranth (pigweed), dandelion, red clover, watercress, and chickweed.

By the way, you can even make vodka out of Japanese knotweed!


WD-40 oil

The spray oil is popular for its wide range of uses and it is even good for killing off thistles.

Congratulations, you now discovered one extra use!

Just spray some on the invasive plants and watch them wither and perish.


So there you have it, your own guide to dealing with invasive plants in your garden. Natural methods are highly effective when combined together – choose several of the above methods for maximum effect.
