Weeds have long been a persistent problem for gardeners, thriving in almost any conditions and often appearing in large numbers after periods of sunshine and rainfall. This pattern has been particularly noticeable in the UK recently.
Rachel Roberts, a member of the Gardening UK Facebook group, recently asked if boiling water could be an effective alternative to white vinegar, salt, or harmful chemicals for killing weeds in patio crevices. She inquired: “To those of you who use boiling water to kill the weeds growing in the patio, how often and for how long do you do it to see a difference?”
Group members responded with their experiences. Helen Brooks said: “I have found it depends on the weed – most of my patio weeds reacted pretty quickly. I use boiling water on my driveway.”
Rachelle Breakspear shared: “Poured hot water on the weeds and next day they were burnt to a crisp, then I pulled them out and not seen any since.”
Sandra Lovett advised: “As soon as you notice the weeds put boiling water on it. I go round every week with the kettle my drives weed-free.”
Annie Searle offered her routine: “I check on mine once a week. Each time they regrow the weeds seem to be weaker and take longer to come back.”
John Gardner suggested: “When you see green shoots. Do a weekly ‘patrol’ during the growing season. They’ll die the same day and shrivelled to nothing in a couple more days if you use this. It’s an amazing water method.”
Gardening enthusiast Jazz Bah shared her positive experience, stating: “I saw a notable difference the next day. I did mine about a month ago and have not done it since. Dog friendly and I’m not averse to weeds as such, just not on my path.”
While boiling water can be effective in killing weeds, caution is advised due to its potential to harm desirable plants. Using a tea kettle with a precise spout and an insulated handle is recommended for this weed management technique.
The design of the spout ensures targeted application of the boiling water on undesirable plants, as the kettle cleverly maintains the water temperature. Care should be taken to pour judiciously to avoid collateral damage to adjacent lawn or ornamental flora.
For those pursuing even superior results, horticulturists may opt to trim back most of the unwanted vegetation before applying the scalding treatment directly to the roots within their gardens.
