Weeds are a common garden nuisance, especially between patio slabs and paving stones. Hand-pulling is laborious, and chemical weed killers pose risks to other plants and wildlife. Seeking a better solution, a writer tested a homemade remedy using three kitchen staples: white vinegar, salt, and washing-up liquid.
Surprising Results Overnight
The mixture, applied with a spray bottle, was left on weeds overnight. By the next day, the weeds had withered and died, making removal much easier than dealing with living plants. The writer expressed genuine surprise at the effectiveness, given the number of weeds.
The recipe costs next to nothing, as all ingredients are common household items. It eliminates the need for harsh chemicals. The writer plans to make another batch once the current bottle runs out.
Application Tips
For best results, apply the mixture on a bright, sunny day to prevent rain from washing it away. Blogger Moral Fibres advises against using it on weeds in soil, as it can increase soil acidity, making it more suitable for patios and paved areas.
How to Make the Weed Killer
Ingredients:
- 500ml white vinegar (45p per litre at Sainsbury's)
- Two tablespoons salt (75p per 750g bottle)
- Two teaspoons washing-up liquid (62p per 500ml bottle at Asda)
- Spray bottle
Method:
- Pour vinegar and salt into the spray bottle or a jug, stirring until dissolved.
- Add washing-up liquid and stir well. If using a jug, transfer to the spray bottle.
- Remove any insects from the weed.
- Spray the mixture directly onto the weed's leaves, giving a good soak.
- For large weeds, pour some mixture onto the plant and spray the leaves.
Weeds begin to wilt within a few hours. After 24 hours, they fully died back.
