For this reason, many gardening experts recommend limiting salt-based treatments to places where vegetation is unwanted permanently.
Where This Spray Works Best

Ideal locations include:
• Driveway cracks
• Sidewalk edges
• Gravel paths
• Patio joints
• Walkways
These areas typically benefit from long-term weed suppression and are less likely to be used for future planting.
Where You Should Avoid Using It
Be cautious when using this mixture near:
• Vegetable gardens
• Flower beds
• Newly planted shrubs
• Lawn areas
• Tree root zones
In these locations, salt may negatively affect desirable plants and soil quality.
Tips for Better Results
Always spray directly onto the weed leaves rather than soaking the surrounding soil.
Treat weeds when they are actively growing and have plenty of leaf surface exposed.
Repeat applications may be necessary for particularly stubborn species.
Monitor treated areas regularly and remove dead plant material when appropriate.
The Bottom Line
This homemade weed-control mixture combines vinegar, salt, citric acid, and dish soap to create a powerful solution that can quickly damage unwanted weeds. It is affordable, easy to prepare, and especially useful for driveways, sidewalks, patios, and other hardscape areas.
