Can vinegar be used in combination with salt to kill weeds? Yes, vinegar and salt can be effectively combined to kill weeds. This natural weed killer works by dehydrating and disrupting the growth of unwanted plants. It’s an eco-friendly alternative to chemical herbicides, ideal for small-scale use in gardens and driveways.
How Does Vinegar and Salt Kill Weeds?
Vinegar contains acetic acid, which is effective in breaking down plant cell membranes. When applied to weeds, it causes them to dehydrate and die. Adding salt enhances this effect by further dehydrating the plants and preventing them from absorbing water. This combination is particularly useful for killing annual weeds and grasses.
What Types of Vinegar and Salt Should You Use?
Using the right types of vinegar and salt is crucial for the effectiveness of this natural herbicide.
- Vinegar: Household vinegar with 5% acetic acid works for young, tender weeds. For tougher weeds, horticultural vinegar with up to 20% acetic acid is more effective.
- Salt: Table salt or rock salt can be used. Ensure it dissolves well in the solution for even application.
