I’ve tried so many various methods to weed my drive (Picture: Steffan Rhys) This text accommodates affiliate hyperlinks, we’ll obtain a fee on any gross sales we generate from it. Be taught extra
The weeds on my driveway are a continuing supply of stress. I’ve a block paving driveway made up of hundreds of particular person bricks — and for a minimum of a part of yearly each single one in all them is surrounded by a hideous mixture of weeds, grass and moss.
When the driveway is freed from weeds (normally after hours of back-breaking laborious work) it appears vivid and wonderful. However when the weeds have taken over, it appears terrible and I am embarrassed to indicate my face on the road. One neighbour even spent days clearing it of weeds for me — however they rapidly got here again to the devastation of us each.
I’ve tried every thing from painstakingly scrubbing round a number of thousand bricks with a wire brush (which had my again begging for mercy) to filling within the gaps between the blocks with kiln-dried sand. I additionally tried vinegar and got here shut to purchasing a elaborate gadget which might have burned them away — till I realised how lengthy it will take to individually burn hundreds of weeds.
However I lastly discovered the strategy that was more practical than every other. Not solely did it take far much less time than every other however, weeks after doing it, solely a tiny variety of weeds had cropped again up. Beforehand they normally returned even worse than earlier than. It has been some time now so my driveway does want weeding once more and it is unquestionably the strategy I will use once more. Firstly, listed below are the strategies I attempted to rid my driveway of weeds earlier than discovering the one that really labored.
Scrubbing with wire brush

A superb high quality weed wire brush did a terrific job of getting in between each nook and cranny and shredding the weeds inside, which got here away pretty simply. Nonetheless, it was in a short time obvious that I used to be not killing the weeds at their roots and that they’d quickly develop again. It was additionally back-breaking work which took hours. I persevered and scrubbed each inch of my driveway, which regarded unbelievable — for a couple of week. My again hadn’t even recovered by the point the weeds reappeared.
The wire brush methodology taught me that I wanted to stop weeds from having the ability to develop within the gaps between the bricks — so I attempted setting sand. That is sand that you just brush into the cracks then flippantly water in order that it turns laborious like cement and would not enable weeds to develop by way of. It sounded nice in concept.
But it surely did not work out in observe. It grew to become rapidly clear that I would wish an enormous quantity of it to cowl even my modest driveway. However a lot worse than that was that after I sprinkled water over a small check space of about ten sq. ft, it additionally set over the bricks themselves, giving them a hideous uninteresting gray hue. They regarded filthy and horrible.
I additionally used kiln-dried sand, a tremendous, dry sand that fills the joints and is supposed to create a robust, interlocking construction that resists weed progress, even with out water. It regarded much better than the setting sand I might used, but it surely did not cease the weeds getting by way of.
Weed killer

It was apparent in a short time that this methodology can be extremely inefficient, time-consuming and finally pointless. After shopping for a bottle of weed killer and beginning to spray every particular person weed by hand, I realised that I would wish a number of bottles and hours of time to get it completed. And I additionally knew that given it will solely kill the weeds at the moment there, it will do nothing in any respect to stop new weeds rising. The spray did kill the weeds it touched, but it surely was not the precise answer for my drawback.
Bleach
The web is filled with warnings about utilizing bleach as a weed killer, primarily for its adversarial results on any soil close by. This was not a difficulty for me as I used to be utilizing it on a driveway with no soil wherever close to it however I nonetheless did not just like the considered pouring gallons of bleach all around the flooring. However one other key cause for this was its effectivity. I would wish an enormous quantity of bleach to cowl the world. I additionally anxious about how I might wash the bleach off when it had killed the weeds. And, because the recommendation from gardeners on-line was that bleach does kill weeds on the floor however doesn’t kill the roots, it appeared like it will be largely wasted effort anyway.
Vinegar, lemon juice and boiling water
I didn’t attempt these strategies as a result of my colleagues had completed the work for me. They examined 4 pure methods of killing weeds: Phoebe Cornish utilized vinegar to weeds and stated “the weeds regarded colourless and shrivelled inside a couple of hours of soaking them within the vinegar answer”.
She added: “And after I checked again the next morning, I used to be really impressed with the effectiveness of this gardening hack. It’s an effective way to flatten and weaken weeds earlier than pulling them out of the bottom, but it surely doesn’t exchange the necessity to dig out the roots to stop them from rising again.”
One other used lemon juice however discovered it usless, saying: “If something, the weeds appeared to have grown 24 hours later.” And I can not even start to think about I might get sufficient lemon juice to kill weeds over a big space. I might want my very own lemon farm.
One other methodology tried was boiling water and, though she instantly “noticed the dandelion leaves and flower wilt dramatically”, the weed nonetheless remained 24 hours later as a result of the basis was not destroyed.
The profitable methodology: salt
Rock salt labored the perfect for me (Picture: Getty)
I had heard about salt being good for killing weeds however I used to be spurred into motion by my neighbour saying she had seen extraordinary outcomes from utilizing it. Not solely did it kill weeds — it additionally stopped them rising again, she stated. As a gardener with a beautifully-presented home back and front, she was somebody I knew I ought to hearken to.
She wasn’t the one one singing the praises of salt: “Salt actually does make a terrific weed killer as it’s going to kill absolutely anything that grows,” Nationwide Backyard Bureau member and Laidback Gardener, Larry Hodgson, informed Houses and Gardens, although he added: “However [it’s] so poisonous it merely cannot be really helpful in most backyard settings.”
Not solely does salt kill the leaves if utilized by spraying but additionally the roots if watered in, individuals stated. On some web sites, individuals stated salt “primarily sterilises” the soil “stopping vegetative re-growth”. On one other, somebody wrote: “When you salt the soil, no plant will ever develop there once more.”
Methods to use salt to kill weeds

All this reward for salt sounded promising so I purchased 20kg of rock salt from Amazon (which turned out to be an terrible lot of salt — you should purchase it right here). I already owned a strain sprayer with a big capability of a minimum of 10 litres (you’ll be able to see an instance right here).
The primary methodology I used was so as to add a big quantity of the rock salt to the sprayer then I added a number of litres of heat water. I stirred with a big plank of wooden to dissolve the salt as a lot as I might then I started to spray the weeds. As with a number of of the strategies above, I realised this was going to take me a very long time (although it was far faster than individually spraying weeds with weed killer from a hand-held bottle).
So, to hurry issues up a bit, I made a decision I’d simply take the lid off the strain sprayer and tipped the salt water combination out over as extensive an space as I might. With just some refills of my giant strain sprayer, I used to be in a position to cowl your entire drive pretty rapidly. I added extra clumps of rock salt to particulalry weed-ridden areas across the fringe of the drive, the place a number of filth and sand had accrued through the years and the weeds had been at their worst.
The outcomes
Inside a couple of hours the weeds had been shrivelled and regarded very useless certainly. Admittedly, giant elements of my drive had been now lined in piles of rock salt and white resin left behind by the salt water. However I merely washed this off a couple of days later with an influence washer (a hosepipe would work simply as nicely).
Most significantly, the weeds had been unquestionably useless. And a number of other weeks later, whereas some new weeds had begun to develop, they appeared at nothing just like the fast fee at which that they had beforehand returned. So it seems there’s reality to the declare that salt makes the soil inhospitable to crops rising there.
You clearly would not wish to use this methodology in a backyard the place you wish to kill weeds however hold different crops and flowers, because the salt would wipe out every thing. However for a patio or driveway, it simply is perhaps the answer you’re searching for.
My colleague, Angela, had the identical outcomes. When she examined salt as a weed killer, she stated: “9 hours later, the weeds had been fully useless, so I used to be simply in a position to dig them out. I did not use a elaborate software for this; an everyday screwdriver sufficed. Curious as as to if the weeds would reappear, I checked again in on the world over the following two weeks, and no weeds appeared to have grown again.”
