How to make weed killer with two kitchen ingredients you already have at home

It can be hard to find a good and safe weed killer to tackle your garden.

But the most effective one may already be sitting in your kitchen.

Expert Michael Griffiths, known as The Mediterranean Gardener, has shared a simple recipe using two common ingredients to eradicate pesky weeds.

"The first ingredient to use is distilled vinegar," he said in his video, adding that it acts as a herbicide which means it kills weeds.

The next ingredient is bicarbonate of soda, but you have to be careful adding this in, Griffiths warns.

"Don't add too much of it at once [to the vinegar] or it will fizz everywhere. Instead, add it slowly mixing it as you go."

In the captioned he said you must mix it together until the solution is completely clear, otherwise it will clog your spray bottle.

He assured his followers that this recipe – which calls for two parts vinegar to one part bicarbonate of soda – will be a "more effective weed destroyer

"Give the weed a good soaking and it will be finished before you know it," he said.

Commenters shared their own concoctions, with one saying, "I use vinegar and salt plus put in a splash of washing up liquid. So the mixture sticks to the plants. Works wonders."

Another said, "Boiling water straight out of the kettle works best."

Some followers believed that this recipe could be replaced by simply using salt, but Griffiths disputed this in a comment.

"If you're going to say mixing the two neutralises itself.

"This is a Gardener's World recipe who are saying councils are trailing this as a weed killer - the only reason I can think of is this. The outcome of a 1:1 mix would create a neutralised solution. Becoming sodium acetate, Co2 and water.

"I imagine a 2:1 mix means you're left with a distilled vinegar, sodium acetate and water mix. Sodium acetate has a much lower impact on soil than sodium chloride. It has a minimal impact on soil structure and degrades in the soil quickly.

"So what you have is a salty, acidic mixture that doesn't have long term effects on the soil as if you were using vinegar and sodium chloride (edible salt)."
