How do I keep grass from growing between paver stones?

Paver stones are a popular choice for walkways in a garden. While they add a quaint beauty to the landscape, grass growing between them can be a problem. To keep grass from growing between paver stones, be sure to install them on a thick base of tamped down sand and fine pebbles. This bit of extra work in installation will prevent a lot of work killing grass later. If grass is growing between the pavers, you can purchase grass killer that will kill grass and prevent its regrowth for up to a year. Apply this to growing grass in small amounts, and then pull it up when it turns brown.
