Weeds sprouting between patio slabs can be a persistent nuisance for gardeners, but a cost-effective homemade solution might already be in your kitchen cupboards. As many households prepare to refresh their gardens ahead of summer, removing weeds that have emerged during damp winter months becomes a priority. Fortunately, a straightforward DIY weed killer requiring just three common household ingredients offers a way to clear these unsightly plants and prevent their return.
Social Media Gardening Tip Goes Viral
The advice originated from the Mrs Hinch Gardening Tips Facebook group, where one woman sought help for weeds in her block paving, expressing frustration at their rapid regrowth. Responses flooded in, with numerous members recommending a mixture of white vinegar, washing-up liquid, and salt to destroy weeds effectively.
User Testimonials and Recommendations
One commenter shared, "I use white vinegar, washing-up liquid and salt. It works fab; I swear by it." Another added, "Salt, vinegar, water and washing-up liquid mixed and sprayed on the area." A third contributor provided additional guidance, noting that replacing silicone sand in block paving can help prevent wind-borne weed seeds from taking root after treatment.
Expert-Backed Recipe for Weed Elimination
Wendy Graham, founder of the environmental blog Moral Fibres, advocates the same solution. She advises filling an empty spray bottle with one litre of white vinegar, three generous tablespoons of salt, and three teaspoons of washing-up liquid. This concoction can be applied directly onto weeds to destroy them and inhibit regrowth.
Affordable Ingredient Costs
The ingredients are remarkably inexpensive, making this a budget-friendly option. Table salt can be found for as little as 40p online through M&S, with supermarkets like Morrisons and Asda offering it for 65p and 70p respectively. White vinegar is most affordable at Tesco, priced at just 35p, while washing-up liquid costs 62p at Asda and Tesco. In total, acquiring everything needed for this tip can cost as little as £2.72, though prices may vary slightly.
Why This Method Works
The combination of white vinegar, salt, and washing-up liquid creates a potent weed killer. Vinegar acts as a natural herbicide due to its acetic acid content, which dries out weeds. Salt dehydrates plants and soil, preventing regrowth, while washing-up liquid helps the mixture adhere to weed surfaces for better penetration. This eco-friendly alternative avoids harsh chemicals, though users should apply it carefully to avoid damaging desired plants.
As gardening season approaches, this homemade spray offers a simple, low-cost way to tackle patio weeds, backed by both social media enthusiasts and horticultural experts. With ingredients readily available and easy to mix, it provides a practical solution for maintaining a weed-free outdoor space.
