Gardening experts have unanimously recommended a homemade weed killer for patios and driveways this summer, offering a natural and budget-friendly alternative to chemical treatments.
As summer progresses, weeds are thriving alongside garden plants, appearing on lawns, patios, and driveways. While garden centres display a range of chemical weed-control products, experts suggest that simple household ingredients can be just as effective.
Expert-Backed Homemade Solution
When five gardening experts were asked about the best approach to driveway weeds, all recommended the same method: a mixture of white vinegar, washing-up liquid, and water. This solution should be sprayed directly onto weeds on a dry, sunny day for optimal results.
Luke Newnes, garden expert at Hillarys, explained: "Start with a good clear-out. I like to begin by pulling out any weeds that have already pushed through. If you can, get the whole root, especially with dandelions and plantain, because anything left behind tends to grow back stronger."
He added: "Use a natural weed killer you probably already own. One of my favourite tricks is a mix of white vinegar, a little washing-up liquid and water. Spray it directly onto weeds on a dry, sunny day. The sun helps it work faster, and you'll usually see them wilt within hours."
Alternative Methods and Precautions
Andy McLaughlin, sales and operations director at RF Paving, suggested a similar approach, starting with manual removal before treating with vinegar, boiling water, or salt. He recommended mixing vinegar with 5% to 20% acetic acid with washing-up liquid to help it adhere to weed roots.
For those without vinegar, boiling water poured directly onto weeds can provide a quick fix, though it may not eliminate the root system. Adding salt to the water can tackle more persistent weeds, but caution is advised as excessive salt can damage soil and paving.
Jessica Mercer, horticulturist at Plant Addicts, advised pulling small weeds after rain when roots slide out more easily. She noted that vinegar should be applied with eye protection and kept away from garden plants to avoid damage.
Preventing Weed Regrowth
To keep weeds from returning, regular sweeping and re-sanding driveway joints are recommended. Luke Newnes emphasised: "Weeds hate tight spaces, and fresh sand helps block the light that encourages new growth."
