Weeds can grow in even the smallest cracks in a patio if you don’t take precautions to prevent them. When you properly install pavers, weeds have a difficult time growing up through the spaces between them.
How to Get Rid of Weeds on a Paver Patio
Polymeric sand also improves the durability of your patio, locking pavers together so that weeds can’t find a place to grow. Because it’s bonded to itself and the pavers, polymeric sand resists erosion, protecting not only the pavers but also the base materials.
Preventing Weeds From Growing on a Paver Patio
The high concentration of salt in this formula prevents them from growing back.
Getting rid of weeds can seem like a never-ending chore. They’re not just garden pests; they’re also an eyesore when they gather between the brick pavers that are usually so attractive. This is especially a problem if there are gaps between the pavers rather than those that are interlocking. To keep weeds at bay in those spaces, adopt one or more control techniques, some of which are put in place before laying the bricks.
Dig into the soil between the pavers and plant a groundcover that is hardy in your area and is tolerant of the sunlight conditions where the pavers are located. Plant individual plants as deep as the nursery containers, and at the closest recommended spacing for quick coverage. For example, blue star creeper (Isotoma fluviatilis) — which is hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9 — makes an excellent groundcover for such purpose. In mild Mediterranean climates, you could also plant Bowles’ common periwinkle (Vinca minor “Bowles”) in USDA zones 4 to 9.
Lay a landscape or geotextile fabric before laying new pavers. After installation, fill the gaps between the pavers with stones to further inhibit weed growth. Note, however, that landscape fabric can inhibit water drainage, so ensure that the soil is well-draining by amending it with organic matter before application. Also, regularly remove debris that accumulates between the pavers.
Before applying sealant, you need to re-fill the spaces between pavers with sand.
The polymer sand is too hard and won’t allow the sealant to penetrate.
Step 3: Chemical-Free Options
Here at Outback, we recommend sealing your patio. You can choose a matte finish sealer or a glossy variety that will look shiny and wet.
Now it’s a jungle out there, with weeds and grass sprouting between the pavers like a primeval forest.
Step 5: If You’re Planning A New Patio
You can choose to fill the cracks between pavers with a polymer sand. This filler, once wet with a hose, turns hard, almost like mortar. It will make it tougher for weeds to take root.
