Weeds can overtake a patio in late summer, but there is a really simple way to kill them and stop them growing back using an everyday household object you likely have sitting in your kitchen.
Summer is gradually coming to a close, with many plants beginning to lose their vitality, yet weeds are doing precisely the opposite — thriving at this time of year. By late August, numerous green, leafy weeds will start appearing, and despite their diminutive size, they can prove difficult to eliminate due to their robust root systems.
Many prevalent varieties of weeds, such as dandelions, can establish their roots long before their foliage becomes visible, meaning that even if you spend an entire afternoon pulling at the leaves, they’re likely to reappear within just a few weeks. Patio weeds can be especially persistent, as the gaps between slabs are typically warm and moist enough for them to develop exceptionally long roots, rendering most natural remedies too feeble to make any impact.
Nobody wants to drench their garden in harsh chemicals that could damage wildlife, but fortunately, Sophie Webb, creator of What Sophie Does, has shared a straightforward method to eliminate patio weeds using just one item that everyone has in their kitchen.
Sophie said: “Boiling water is one of the simplest, cheapest and most effective ways to get rid of weeds growing through the cracks in your pavement or paths.
“Just pour it directly onto the weeds and the heat destroys the plant right down to the root with no harsh chemicals, no expensive products, and no harm to the environment. Perfect for driveways, patio edges and garden paths.”
It may sound almost too straightforward, but weeds will break down at temperatures around 100°C, meaning that filling a kettle and pouring boiling water directly over them is typically sufficient to do the job.
Boiling water effectively destroys the enzymes within the weed, rendering them unable to function.
Using a kettle to tackle weeds requires just 10 minutes of effort and, best of all, won’t cost you a single penny — making it well worth giving it a go to see whether it does the trick.
There are, however, a few drawbacks to this method: it can take a day or two to completely eliminate a weed, so a little patience may be required.
For particularly deep-rooted weeds embedded in your patio, a considerably greater volume of boiling water will be needed, and you may have to repeat the treatment several times before fully eradicating it.
That said, boiling water remains one of the most reliable methods for dealing with patio weeds, meaning there’s no need to resort to chemical products or less effective remedies such as vinegar, baking soda, or salt.
How to kill off patio weeds using just a kettle
Simply fill the kettle, allow it to boil, then carefully carry it outside to the patio.
Exercise particular caution when handling the boiling water, as this is the most hazardous stage of the process. Ensure your path is free from obstacles and keep children and pets well clear before lifting the kettle.
Upon reaching the weeds, position yourself steadily and pour the boiling water carefully and directly over them. Pour gradually to reduce splashing, and take care not to spill the water on yourself or surrounding plants, as boiling water can damage or destroy virtually any plant it touches.
The weeds should start to droop within a matter of minutes. After several hours, they ought to look wilted and brown; though especially resilient or deeply-rooted weeds may require longer to perish entirely.
Once the weeds have died off, simply brush away what remains with a broom and bin them. Your patio will appear considerably neater with minimal fuss and without requiring a chemical weed killer.
