You can make an effective DIY weed killer for weeds growing between paving stones using common household items. These methods work best on small, visible weeds (they don’t fully prevent regrowth long-term).
🌿 DIY Weed Killer (Household Method)
🧴 Option 1: Vinegar + Salt + Dish Soap (most effective)
Ingredients:
- 1 liter white vinegar
- 2–3 tbsp salt
- 1 tsp dishwashing liquid
How it works:
- Vinegar burns plant leaves
- Salt dehydrates the roots
- Soap helps it stick to the weeds
Method:
- Mix everything in a spray bottle
- Spray directly onto weeds (avoid nearby plants)
- Apply on a hot, sunny day for best results
- Weeds usually wilt within 24–48 hours
🔥 Option 2: Boiling Water (simplest)
Method:
- Boil water
- Carefully pour directly onto weeds between stones
- Repeat after a few days if needed
👉 Works well for young weeds and moss
🍋 Option 3: Vinegar only (safer for surrounding area)
- Spray undiluted white vinegar
- Best for small, new weeds
⚠️ Important warnings
- ❌ Salt can damage soil long-term (avoid using near garden beds or lawns)
- ❌ Don’t spray on plants you want to keep
- ❌ Vinegar can stain some stone types over time
- ⚠️ Wear gloves and avoid inhaling spray mist
🧠 Best practice (for long-term control)
DIY sprays kill visible weeds, but to reduce regrowth:
- Pull weeds after rain (easier roots removal)
- Fill gaps with sand or polymeric sand
- Sweep regularly to prevent seed buildup
If you want, I can give you a non-chemical permanent solution for paving gaps or a pet-safe weed killer
