Weeds are a real nuisance when it comes to the upkeep of your garden, unless you're into the look of the rewilding trend, and can be a reoccurring nightmare for years. This becomes especially irksome when they start growing between pavement flags and broken concrete. 

The hack, which originated on TikTok, was shared by Dr Janine Bowring and consisted of her making a saltwater solution with one part salt and two parts water. She is then seen stirring the mixture to pour it over the weeds growing through the driveway and pavement gaps to kill any vegetation.

Gardening expert at PriceYourJob, Harry Bodell has shared his professional thoughts on the hack and whether it works effectively. He says, "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." 

He goes on to explain that this salt solution will also prevent any further growth of weeds. Harry explains, "There are certain ions present in salt which can be toxic to plants when accumulated in high concentrations, it interferes with natural processes such as photosynthesis, leading to cell damage and dehydration of the plant." 

Although the TikTok video is no longer available, Harry shared his recommended method for using this natural solution. Using natural solutions such as this is a great sustainable garden idea as it reduces the amount of chemicals around your plants and of course around you too. 

"Once you’ve prepared your salt solution, lightly pour the solution over gaps in between paving slabs on garden paths, specifically concentrating on areas that have weeds currently growing through," Harry advises. "It’s important to do this on a dry day so humidity and rain don’t wash away the solution." 

Leaving the solution overnight will dry out the weeds to their roots, which makes removing the weeds the next day much easier. 

If you're worried about weeds growing in amongst your other plants use old towels in your garden as weed barriers, the salt solution will damage your other plants.
