If you do not want to constantly dig up weeds between your pavers, it is important to treat the area with a weed killer that prevents weeds from growing back. To do this, you don't have to go to the store. Instead, you can use ordinary salt to prevent weeds from growing among your pavers. However, you should exercise caution when applying the salt if you have plants you do not want to kill living near your pavers. Using too much salt can kill plants surrounding the pavers.
Target and kill specific weeds if you have plant life surrounding your pavers that you do not want to kill. To do this, simply drop a pinch of salt at the base of each weed. Once the salt absorbs into the ground, it prevents the weeds from being able to absorb water through their roots. Because of this, the weeds eventually dry up and die.
Spread salt across the surface area of widely spaced pavers among which weeds are growing. Anything more than a pinch of salt per weed prevents additional weeds, and other plant life, from growing back in the area. The more salt you use, the longer it will be before plants are able to grow back around the stone or bricks. However, the more salt you use, the greater potential that the salt will negatively affect plant growth surrounding your pavers.
Mix 1 cup of salt with 2 cups of hot water and pour it over areas, such as narrow cracks between pavers, that are hard to get to.
