Long Island contractors and homeowners alike often face a persistent issue with weeds between pavers, whether on patios, walkways, or driveways. Weed growth between pavers not only disrupts the clean lines of a hardscape but can also compromise its structure over time.
This guide outlines the best methods for removing and preventing weeds between pavers, from manual removal techniques to professional-grade chemical and natural solutions, all using masonry supplies from our Long Island masonry yard. Whether you’re managing a commercial paver installation or maintaining a backyard patio, these tips will help you keep a clean, safe, and weed-free surface year-round.
Why Weeds Grow Between Pavers (The Problem)
Weeds thrive in paver joints due to the buildup of soil, dust, and organic debris that create mini planters for seeds. Windblown seeds land in these cracks, finding moisture and decaying material perfect for germination. Improper paver base installation or lack of joint filler can further enable weed intrusion. Over time, weeds can widen joints, shift pavers, and present safety hazards, not to mention they look terrible! For commercial properties, visible weeds may signal poor maintenance. The key to a weed-free surface is to block these opportunistic plants from taking hold in the first place.
Manual and Mechanical Weed Removal Methods
Manual and mechanical removal methods are effective for small to medium weed issues and those avoiding chemicals. Techniques include:
- Hand Pulling & Weeding Tools: Best done when the soil is moist; use crack weeders or wire brushes for deeper root removal.
- Power Washing: Ideal for large areas; clears weeds and debris but requires refilling joints with sand afterward.
- Flame Weeding: Propane torches can singe weeds quickly, so safety precautions and care around paver surfaces are crucial. Avoid relying solely on string trimmers, which only cut tops off weeds, leaving roots intact.
Natural Weed Control Solutions
Natural weedkillers provide eco-conscious alternatives for smaller paver areas:
- Boiling Water: Effective on young weeds; pour slowly to avoid scalding and sand erosion.
- Vinegar Spray: White or horticultural vinegar desiccates weeds. Add dish soap for adherence and avoid contact with stone surfaces.
- Salt & Baking Soda: Dried applications can inhibit growth but must be used sparingly to avoid soil and concrete damage.
- Corn Gluten Meal: A natural pre-emergent that blocks seed germination; ideal after initial weed removal. Natural methods are safest for pets and children, though they may require repeated applications.
Chemical Weedkillers for Paver Joints
For persistent or widespread weeds, chemical solutions offer powerful control:
- Post-Emergent Herbicides: Products like Roundup kill existing weeds to the root. Use on calm, dry days and follow safety instructions.
- Pre-Emergent Herbicides: Create a barrier to prevent seed germination. Apply in early spring and reapply as needed.
- Long-Lasting Formulas: Brands like Ortho GroundClear keep joints weed-free for up to 12 months. Ideal for commercial walkways and driveways. Use chemical herbicides with caution near lawns and gardens, and always adhere to label guidelines.
Artificial Turf
For those seeking a green look without the maintenance, artificial turf is another long-term solution. When professionally installed with proper edging and base prep, it offers the visual appeal of grass while completely eliminating weed issues between joints or seams. Explore how to use artificial turf in landscaping to see if it’s right for your project.
Installation: Preventing the Problem Before It Starts
The best defense against weeds is a proactive approach during installation. A well-built foundation and the right joint materials will drastically reduce weed growth:
- Proper Base Installation: A deep, compacted gravel base resists weed infiltration from below.
- Weed Barrier Fabric: Adds an extra layer of protection under the base layer.
- Polymeric Sand: Hardens after water activation, forming a weed-resistant joint filler. Can be used to retrofit older patios.
- Resin-Based Joint Compounds: More durable and permeable, suited for larger joints or upscale installations.
Maintenance: Keeping Weeds Out for the Long Haul
Even with perfect installation, ongoing care keeps your pavers looking their best:
- Paver Sealing: Locks in joint sand, repels debris, and enhances aesthetics. Apply a few months after installation, then reapply every 2–5 years for best results.
- Regular Upkeep: Sweep often, remove new sprouts immediately, and reapply joint sand as needed to maintain a clean look and strong weed barrier.
