Preventing weed growth under synthetic grass starts with proper installation and ongoing maintenance. One of the critical actions is ensuring a clean, level base before laying synthetic grass. Remove all existing vegetation, including deep-rooted perennials, to prevent future infestations. Use a landscaping fabric underneath the synthetic grass. This layer serves as an impenetrable layer that deprives weeds of the conditions they need to sprout. Ensure seams are overlapped by a minimum of 6 inches to prevent infiltration points.

Once laid, keep the surface clean by frequently grooming the blades to preserve natural texture and to prevent debris buildup. Leaves, dirt, and organic matter can collect and rot into nutrient-rich sludge, creating a nutrient-rich layer that encourages weeds to take root. Employ a power blower or firm-bristled brush to clean the surface consistently, especially in autumn season.

Minimize unnecessary irrigation. While synthetic grass doesn't need water to grow, standing water can form in uneven spots or seep through seams and permeable backing, creating moist environments that invite root invasion. Verify that the sub-base has adequate slope and drainage to stop pooling underneath the surface.

Should unwanted plants surface, refrain from yanking them out as this can tear the synthetic substrate or shift the infill material. Instead, spray a glyphosate-free, synthetic-safe formula that won’t degrade the fibers. Dab the solution onto the foliage with a small applicator to minimize overspray onto surrounding plants or soil. Vinegar solutions can also be effective for spot treatment though they may demand consistent reapplication.

Finally, inspect the edges of your synthetic lawn regularly—weeds often find their way in through gaps along borders or at junctions with pavers, 熊本 人工芝 業者 slabs, or earth. Seal these edges with landscape adhesive or add a rigid barrier such as aluminum, plastic, or stone to form an unbroken defense.

By combining good installation practices with consistent cleaning and targeted weed control, you can ensure your artificial turf remains beautiful and clean for many seasons.
