You can use chemical herbicides to treat weeds on pavers as well, and there are two general types: pre-emergent and post-emergent. Pre-emergent herbicides work on plant seeds and seedlings, and they form a barrier to prevent germination.
Vinegar, like baking soda, is a natural household product that is safe to use as a weed killer. Vinegar has acetic acid, which draws the moisture out of plants causing them to die. Vinegar is extremely fast-acting and will result in brown, withered weeds within 24 hours.
Post-emergent herbicides work on actively growing weeds and are divided into two categories: selective and non-selective.
Method #4: Pressure Washing
Simple household baking soda may be all you need for your weed problems, especially if you want to kill weeds growing near decorative plants you’d like to keep. Baking soda is a natural product that will not contaminate your property or landscaping and is safe for the environment.
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.
Polymeric sand also improves the durability of your patio, locking pavers together so that weeds can’t find a place to grow. Because it’s bonded to itself and the pavers, polymeric sand resists erosion, protecting not only the pavers but also the base materials.
Method #2: Vinegar
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.
