Here are a few simple homemade weed-killer solutions commonly used for weeds growing between patio pavers. These are non-selective, meaning they can kill any plant they touch.
🌿 1. Vinegar spray (most common)
Ingredients:
- White vinegar (5–10% acidity; stronger works faster)
- Spray bottle
How to use:
- Spray directly onto weed leaves on a hot, sunny day
- Avoid nearby plants you want to keep
How it works:
- The acid dries out the plant, causing it to wither
🧂 2. Vinegar + salt solution (stronger, but use carefully)
Ingredients:
- 1 liter white vinegar
- 2–3 tablespoons salt
- A few drops dish soap
How to use:
- Mix and spray directly on weeds
- Best for cracks between pavers
⚠️ Warning:
- Salt can damage soil and prevent future plant growth in that area
- Use only on hard surfaces like stone or concrete
🧼 3. Boiling water (simplest method)
How to use:
- Pour boiling water directly onto weeds
- Repeat if needed
Pros:
- No chemicals
- Very cheap and safe
Cons:
- May require multiple applications for deep roots
🫧 4. Vinegar + dish soap (better sticking power)
Ingredients:
- Vinegar
- A few drops dish soap
How it works:
- Soap helps vinegar stick to leaves longer, improving effectiveness
🌞 Best time to apply
- Hot, dry, sunny days
- When weeds are actively growing
- Avoid rain within 24 hours
⚠️ Important notes
- These methods are non-selective (they kill all plants they touch)
- May not kill deep roots permanently—repeat treatments may be needed
- For tough weeds, pulling roots after treatment is most effective
🟡 Simple summary
Best homemade weed killers for pavers:
- Vinegar spray = safest and most common
- Vinegar + salt = strongest but can damage soil
- Boiling water = chemical-free option
