A kitchen staple can kill patio weeds overnight, and it is completely natural. Weeds often invade patios, gravel paths, and lawns, but a gardening expert says one common ingredient can help eliminate them permanently.
Harry Bodell, a gardening expert at PriceYourJob, explained how to use salt to kill weeds effectively overnight. Saltwater acts as a natural remedy by dehydrating and damaging plant tissues. However, caution is necessary because saltwater can also harm soil and surrounding plants.
How Salt Kills Weeds
Harry explained: "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 added: "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, interfere with natural processes such as photosynthesis, leading to cell damage and dehydration of the plant."
How to Make and Apply the Solution
To prepare the solution, combine one cup of salt with two cups of water, using either rock salt or table salt. Lightly pour the solution over gaps between paving slabs on garden paths, focusing on areas where weeds are growing. Apply on a dry day to prevent rain or humidity from washing away the solution.
Harry said: "Overnight, the solution will work on drying out the plant to the root, making the weed easy to remove the next day."
Caution Advised
The gardening expert advises using the solution sparingly to avoid harming other plants. He warned: "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."
