Use drip irrigation or a soaker hose to water nearby plants. This keeps the water near the plants you want to keep and away from potential weeds in the block paving. Without adequate water, the weeds are less likely to grow.

Spray a chemical herbicide on persistent weeds that regrow. Direct the chemicals to the weeds on a calm day so the herbicide doesn’t blow to other nearby plants. Organic herbicides offer an option with fewer harsh chemicals for less potential environmental impact.

Place landscape fabric underneath the pavers. Cut the fabric to size with scissors and hold it in place with U-shaped pins. Layer the sand bed over the fabric and install the block paving as you normally would.

Remove any existing weeds before installing the block paving. Dig up the roots using a spade or garden trowel. Move the weeds away from the area so they can’t grow again.

Fill the joints between the block paving with polymeric sand, a special sand product that turns into a solid that still allows flexibility once it is misted with water. The solid joints won’t allow weeds to grow up in the cracks.

Block paving offers an affordable way to create pathways or patios in your landscaping, but the individual blocks provide an opportunity for weeds to squeeze in through the cracks. Not only do the weeds look unattractive, they could cause shifting or damage to the pavers. Stopping weeds in paver areas starts with the installation of the walkway or patio. Continued maintenance to control weeds as soon as they appear prevents the unwanted greenery from taking over your block pavers.

Pull any weeds that grow up through the block paving by hand. A putty knife or special weeding knife helps reach weeds that are in the cracks. Remove as much of the weed and root system as possible and dispose of them so they don’t take root again.
