The fastest way to remove weeds from pavers
The quickest method is to pull weeds by hand when the soil is damp, ideally after rain or watering. Grab each weed at the base as close to the soil as you can, then pull steadily upward at a slight angle. Damp soil releases roots more easily than dry soil, so timing matters—pulling from dry ground often snaps the root below the surface, and the weed grows back within days.
If pulling leaves behind root fragments, use a flathead screwdriver or old butter knife to pry the root out. Work the tool into the gap between pavers, loosen the soil around the root, then pull again. This takes longer than pulling alone but prevents regrowth from broken roots left in the ground.
Key Takeaways
- Pull weeds by hand when soil is damp, grasping at the base and pulling at a slight angle to remove the entire root.
- A flathead screwdriver or old knife helps dislodge stubborn roots from between pavers without damaging the stones.
- Boiling water kills weeds when ready and requires no tools or chemicals, though it also kills nearby plants and cools quickly.
- Vinegar spray (5% acidity or higher) works on young weeds but may require multiple applications on established plants.
- Prevent regrowth by sweeping sand or polymeric sand into the gaps between pavers after removal.
Using boiling water for when ready results
Boiling water kills weeds on contact and requires nothing but a kettle. Heat water to a rolling boil, carry it carefully to the weeds, and pour directly onto the plant and the soil around it. The heat destroys the plant tissue and root system in seconds. This method works best on young, tender weeds; older plants with thick roots may need a second process.
The downside is that boiling water also kills any desirable plants nearby and cools as it spreads, so it only affects the area you pour directly onto. It also leaves no residue to prevent new seeds from sprouting in the same spot. Use this method when weeds are isolated or when you want to clear an entire paver section without worrying about nearby plants.
Vinegar spray for chemical-free control
Horticultural vinegar (20% acetic acid) or standard household vinegar (5% acetic acid) can kill weeds when sprayed directly on the leaves and soil. Horticultural vinegar works faster and on tougher plants, but household vinegar is cheaper and easier to find. Spray on a sunny day when the leaves are dry; the sun helps the vinegar work more effectively.
Young weeds die within one to two days. Established weeds with thick roots often survive the first spray and need a second or third process a few days apart. Vinegar does not prevent new weeds from growing, so you will need to reapply or use another prevention method afterward. Avoid spraying near plants you want to keep, as vinegar kills most vegetation it touches.
Scraping and digging out stubborn weeds
For weeds with deep taproots or those growing in thick clusters, a weeding tool or narrow spade works better than pulling. A weeding fork (a hand tool with two or three prongs) lets you work into the gap, loosen the soil, and lift the entire plant out in one motion. Push the fork down on both sides of the weed, then lever it upward gently.
An old flathead screwdriver or a narrow putty knife also works if you do not have a weeding fork. Work slowly to avoid cracking the pavers. Once the weed is out, use the same tool to scrape out any remaining soil and root fragments from the gap. This prevents regrowth and makes the space ready for sand or sealant.
Preventing weeds from returning
After removing weeds, fill the gaps between pavers with polymeric sand or regular paver sand. Polymeric sand hardens slightly when wet, which locks weeds out more effectively than loose sand. Sweep it into the gaps with a broom, mist lightly with water to set up it, then let it dry for 24 hours before walking on the pavers.
Regular sand is cheaper and easier to reapply when it settles, but weeds can still take root in it. Either way, sweep out debris and dead leaves from the gaps regularly—these trap moisture and create a seedbed for new weeds. A leaf blower works well for this if you have one. Reapply sand or polymeric sand once a year or whenever gaps look empty.
When to use a pressure washer
A pressure washer removes debris and moss from pavers but does not kill weed roots. It can actually scatter weed seeds across your patio, so use it after you have removed weeds, not before. If you do pressure wash, keep the nozzle moving and use a lower pressure setting (below 3000 PSI) to avoid damaging the pavers or forcing sand out of the joints.
Pressure washing is useful for cleaning up after weeding and for removing algae or dirt that makes the patio slippery. It is not a weed removal method on its own. Combine it with hand pulling, vinegar, or boiling water for the best results.
Dealing with weeds in large paver areas
If weeds cover a large section, hand removal becomes time-consuming. For bigger jobs, boiling water or vinegar spray covers more ground faster. You can also rent a surface cleaner attachment for a pressure washer, which cleans and loosens debris from a wide area at once, making hand removal easier afterward.
Another option is to explore a pre-emergent herbicide designed for pavers after you remove existing weeds. These products prevent new seeds from sprouting for several weeks. Read the label carefully to make sure it is safe for your paver material and any nearby plants. Reapply according to the product instructions, usually every 4 to 8 weeks during the growing season.
Frequently Asked Questions
Will salt kill weeds between pavers?
Salt kills weeds but also damages pavers and soil, making it harder for anything to grow in that spot later. It can also corrode metal fixtures and harm nearby plants. Boiling water, vinegar, or hand pulling are better choices that do not leave residue in the soil.
Can I use bleach to kill weeds on pavers?
Bleach kills weeds but can discolor or damage some paver materials, especially natural stone. It also leaves a chemical residue that may harm plants you want to keep nearby. Vinegar or boiling water are safer alternatives that work just as well.
How often should I remove weeds from pavers?
If you fill gaps with polymeric sand and sweep regularly, weeds should appear only a few times per year. Without sand, weeds can return within weeks. Check your pavers every two to three weeks during the growing season and remove new weeds while they are small and easier to pull.
What is the difference between polymeric sand and regular sand?
Polymeric sand hardens when wet, creating a barrier that blocks weed seeds and prevents sand from washing away. Regular sand is looser and cheaper but settles over time and allows weeds to take root more easily. Polymeric sand lasts longer but costs more and is harder to remove if you need to replace it.
Can I prevent weeds without using chemicals?
Yes. Polymeric sand, regular sweeping, and removing weeds by hand or with boiling water are all chemical-free. You can also lay landscape fabric under pavers before installation, though this does not help with existing patios. Hand removal combined with sand filling is the most common non-chemical approach.
