How to stop weeds growing back on patio

Salt is another natural product that you can use to kill weeds. Start by using a 3:1 mixture of water and salt and apply to the area very carefully. Keep in mind that saltwater will also kill other plants, so take care to apply it only to the weeds.

To prevent weeds from growing in your paving, you can pour baking soda all over the paved area and then sweep it into the cracks. You should re-apply every four to six weeks. This method works the fastest during spring and fall but can still work during summer.

While it’s hard to get rid of weeds on a patio once they’ve started to grow, you can set yourself up for success when you first install your pavers.

Method #3: Salt

Like the baking soda and vinegar methods, this is effective since salt dries out the plants to the roots and has a lasting effect.

To get rid of weeds with baking soda, moisten them with your garden hose and then sprinkle the soda on top of the entire weed.

Method #2: Vinegar

The high concentration of salt in this formula prevents them from growing back.

Because vinegar is harmful to all plants, it should be applied using a spray bottle ad overspray should be controlled. For longer-lasting results, mix 1 gallon of white vinegar, 2 cups of table salt, and 1 tsp of concentrated dish soap and spray on all the weeds and cracks in the patio.

Stone and brick patios make gorgeous additions to any home. That is, until they become infested with unsightly weeds. Unlike weeds in your garden that can easily be pulled out, the removal of patio weeds involves a bit more ingenuity. Although the process is a little different than weeding your garden, the most effective and long-lasting way to eradicate patio weeds is to remove them by hand. You can also kill patio weeds using products you might already have at home. Finally, once your weeds have been removed, you can take steps to prevent their return.
