Best Natural Weed Killer

[sherrardk]

I have googled this, but what is the most effective natural weed killer (I’m not going to use chemicals even though the weeds are driving me barmy). Thank you :)

Where are the weeds?

[Canary42]

Manual removal.

[sherrardk]

The weeds are in the cracks of a patio.

Boiling water then. About as natural as you can get.

Heat gun..either using flame or (better still) electricity.

[Chipchopper]

Regular use of a hoe.
I've had some success with a strimmer on block paving.

There's no natural liquid that you can use to kill weeds (unless you can get hold of a lot of cat pee, that is - it kills everything in sight!). However there are non-chemical ways of controlling weeds, which are listed on the RHS website:

Ive heard that white vinegar mixed with water will do it, though I havent tried it yet. I think it will kill any plant or grass so be careful.

Cat pee, vinegar, salt, are all chemicals.

Read Kipling's The Glory of the Garden"

Our England is a garden, and such gardens are not made
By singing:-" Oh, how beautiful," and sitting in the shade
While better men than we go out and start their working lives
At grubbing weeds from gravel-paths with broken dinner-knives.

Broken dinner knives! That's the way to do it!

[smurfchops]

Boiling water every time.

Brilliant, I love it :-D

The best answer is to weed them by hand, pull the roots out. Some people use boiling water on them, but a bit of the roots are still there.
