‘Effective’ 70p method naturally kills weeds on patios by ‘dehydrating’ them

Patios and driveways with slabs and pavers can quickly become overrun with weeds.

Regular maintenance of patios, driveways and paving areas can prevent weeds from growing in the first place.

However, if you’ve already got patio weeds, gardening expert Harry Bodell at PriceYourJob, has shared exactly how to get rid of them using a natural method – salt.

Harry has shared exactly how the simple gardening hack works. 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.”

Salt can be bought online and from most local supermarkets. Essential Table Salt costs 70p from Waitrose, Saxa Table Salt costs £1.75 from Iceland and Cook With M&S Table Salt costs 40p from Ocado.

Harry also shared how to use the salt water solution to kill weeds effectively overnight.

He said: “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, and interfere with natural processes such as photosynthesis, leading to cell damage and dehydration of the plant.

“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, the gardening expert also warned gardeners to use the solution sparingly to avoid it affecting other plants.

He added: “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 the future growth of other plants.”

Other methods for banishing weeds include using white vinegar, boiling water, lemon juice and chemical herbicides.
