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.

Selective herbicides can be applied to your whole patio because they target just weeds while having little to no effect on the surrounding grass. Non-selective herbicides will kill every type of plant that they touch, so you should only use them in the middle of your paved area.

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

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.

The goal is to remove debris and sand from the joints while not disturbing the bedding layer that the pavers are resting on. You’ll need to continue to do this regularly to keep the weeds at bay.

Weeds can grow in even the smallest cracks in a patio if you don’t take precautions to prevent them. When you properly install pavers, weeds have a difficult time growing up through the spaces between them.

Preventing Weeds From Growing on a Paver Patio

Let’s look at a couple of ways to prevent and get rid of weeds on a 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.

Prevention is one of the best methods of weed control. With a little regular maintenance, weeds can be avoided in the first place.

Regular Sweeping

Pulling weeds is a classic method of removal but it is only effective if the entire plant is removed, root and all. To do this, reach for the lowest point of the stem and carefully pull the weed. Any roots that don’t come with the plant will grow back. This often results in multiple hand-pulling sessions before the problem is remedied. Hands-on removal is possible at the onset of a weed problem, when only a few weeds are present, but it can become a very labor-intensive and less effective method when there is a severe weed problem.
