Post-emergent herbicides work on actively growing weeds and are divided into two categories: selective and non-selective.
You can also use polymeric sand to fill the joints between pavers to lock the joint together and prevent weed growth. Polymeric sand is not ordinary sand, it is a super-fine sand with additives like silica that form a binding agent when mixed with water to better seal cracks between pavers.
When installing or refreshing pavers, weed growth is something to think about. Getting rid of weeds on your patio can seem like a pain because they are experts at finding places to grow.
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.
Method #5: Chemical Treatments
Baking soda, or sodium bicarbonate, works by overloading the weed with salt, causing it to dry out all the way to the roots and die.
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.
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.
Preventing Weeds From Growing on a Paver Patio
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.
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.

For the best results, spray any weeds at noon, when the sun is at its highest.
Pulling weeds can be a time consuming and highly physical task, with kneeling down taking its toll on backs, necks and knees.
Adding in salt and washing up liquid will tackle the weeds quickly, with results potentially seen within an hour.
All you need to do is generously sprinkle baking soda over the paving stones which have the offending weeds.
You will need to have household ingredients like white vinegar, table salt, washing up liquid and a spray bottle for this method.

You don’t need to purchase a high-strength white vinegar to tackle weeds, household five percent white vinegar will do the job.
White vinegar’s high acidity is ideal for targeting weeds and removing them for good.
So I turned the tables and rather than recommend methods of getting rid of weeds between pavers without trying them, I rejected certain methods without trying them. You’ll see my logic in a minute.
