The trick is to use some salt, water and mix them both together before pouring the liquid over the weeds. 

He said: “This method works by ultimately dehydrating weeds. Salt interferes with the weed’s ability to absorb essential nutrients such as potassium, magnesium and calcium. 

“The disruption in nutrient uptake weakens the plant’s overall health, causing it to dry out from dehydration and die.

“The salt method prevents further growth of weeds. 

"There are certain ions present in salt which can be toxic to plants when accumulated in high concentrations, interferes with natural processes such as photosynthesis, leading to cell damage and dehydration of the plant.” 

Harry goes on to explain how to use the salt water solution to kill weeds effectively overnight.

He said: “Once you’ve prepared your salt solution, lightly pour the solution over gaps in between paving slabs on garden paths, specifically concentrating over areas that have weeds currently growing through.

“It’s important to do this on a particularly dry day so humidity and rain doesn’t wash away the solution.

“Overnight, the solution will work on drying out the plant to the root, making the weed easy to remove the next day.”

However, Bodell also recommends using the solution sparingly to avoid it affecting other plants.

He said: “While salt can effectively kill weeds, it can also accumulate in sand and soil and affect the growth of other plants. 

“Use it sparingly and only on areas you wish to have no plants growing through, as it could impact future growth of other plants.”
