For any green-fingered enthusiast, the untimely appearance of weeds can pose a tedious challenge, often stealing nutrients and greatly impacting the aesthetic of beloved garden spaces. These uninvited guests can come in various forms - paradoxically, even your perfectly manicured lawn could technically be categorised as a weed on some level - but it's those particularly irksome types that sprout stubbornly between patio slabs that really tend to vex us.

Aside from being quite the eyesore, they may also cause significant structural damage if left undeterred for lengthy periods. But how does one manage these rampant botanical invaders proficiently?

Over at the online community Mrs Hinch Gardening Tips, one user delineated her swift triumph over patio weeds deploying a simple, homemade mixture.

Sharing her garden miracle, Hannah Miller exclaimed: "Omg I have just sprayed my weeds on the patio with vinegar, salt and washing up liquid solution and within one hour they were dead. It's amazing, I can't believe it worked so fast. I'm absolutely delighted. I used just under four litres of water, a cup of salt and one tablespoon of washing-up liquid. I first heard about this on another gardening group, didn't expect results, but it worked so well."

The post sparked plenty of feedback, with group members sharing their own success stories. Catherine MacInnes noted: "I can totally agree. Tried this and worked within an hour. Amazing.", reports the Mirror.

Mary McClure Whelan shared her experience: "I used undiluted vinegar on the weeds that were popping up through my monoblock paving and it did the trick. They've not returned."

Adding to the chorus, Margaret Blair commented: "It works, I use it all the time." Julie Barnes chimed in with: "That's all I use."

So why does it work so well? Simply put, both vinegar and salt contain acetic acid which dehydrates plants, leading to their demise.

The added washing-up liquid acts as a surfactant helping the deadly mixture penetrate the leaf pores instead of just sitting on the surface. To achieve optimal results, thoroughly soak those annoying weeds with this homemade weed killer.

But be careful, as its indiscriminate - it wont differentiate between your unwanted weeds and your prized petunias. So if you're dealing with weeds close to plants youd like to keep, aim your spray with precision.
