Paving stones serve as the foundation for many landscaping paths, patios and other installations, and different installers and homeowners desire different looks from their applications. Some people enjoy the visual combining of paving stones and grass, while others find grass inching its way between the stones to be a hassle and an eyesore. One way to stop this grass from growing is to kill it and add a layer of stone or gravel beneath your pavers to make sure no other grass can grow through.

Things you need
- Dishwashing soap
- White vinegar
- Pump sprayer
- Landscape fabric
- Sand or gravel
Mix 29.6ml. liquid dishwashing soap into 1 gallon of undiluted white vinegar. Pour the mixture into a pump sprayer and stir well. The soap will help the vinegar stick better to the grass.
Spray the grass between your pavers thoroughly, coating all of the grass with vinegar. The vinegar will dry out the grass and kill it.
Reapply vinegar every two to three days as needed until all grass is dead. If you do not want any plants to grow in this area, you can also saturate the soil to ensure that nothing grows between the pavers.
Remove the pavers, one at a time or all at once, to expose the soil beneath. Cover the soil with a layer of landscape fabric. This fabric will allow for water to drain during rain, but will prevent any grass from below to grow between the pavers.
Cover the landscape fabric with a 1- to 2-inch layer of sand or gravel. Like the fabric, this material will stop the grass from growing through to the surface, but still allow for safe drainage.
Lay the paver stones back into position. Use a level to ensure that each stone sits flat in the gravel or sand surface. If necessary, add more material to bring a piece up or use a rubber mallet to a position a piece down into place. Make sure the stones are flat across and that they also line up level with each other.
Tips and warnings
- If you need more or less white vinegar you can change the recipe, but keep the ratio of vinegar to dish soap the same. If the vinegar does not appear to work, some professional companies make grass killer.
- Homemade and professional grass killers will kill other plants as well. Never spray on a windy day and keep the spray away from desirable plants.
