How to Stop Weed Before They Grow

Before we mention the steps for weed removal, you can prevent them from growing in the first place.

  • First, you must ensure that the stones are correctly installed.
  • In order to do so, the foundation should be tightly packed.
  • Another thing to keep in mind is that don’t lay plastic underneath the pavers; the joints will keep wet, promoting weed growth.
  • Ensure the pavement is properly sloped to let the excess rainwater direct away; otherwise, stagnant water elevates moss and weed growth.
  • Regularly sweep the area to remove and prevent seed settling between the pavers.

What Are the Ways to Remove Weed?

  • Removing Weed Manually

First, you need to remove the current weed before thinking about the long-term solution. You can use the simplest way by stripping them out using a pair of gardening gloves.

  • While removing the weed, use a knee pad to rest
  • The best time to remove them by hand is after heavy rain.
  • And if you cannot wait till it rains, you can hose down the pavement and remove weeds easily after it lifts.
  • And for stubborn weeds, you can use a billhook.
  • Though this method seems tedious, it has long-lasting results.
  • Use Vinegar

Vinegar is the cheapest, most readily available and most potent weed killer. It is highly effective, especially for annual weeds.

  • For older weeds, use vinegar of higher concentration.
  • For young weeds, simple white vinegar will work.
  • To make a more effective solution, mix two tablespoons of dish soap with approximately 5 litres of vinegar.
  • You can measure and increase the quantity according to the pavement size.
  • Add the solution to a garden spray bottle and sprinkle it into the weeds.

Note: Soap helps the vinegar to stick better on the weeds. Moreover,

  • If you have a smaller area to cover, you can also use the vinegar bottle.
  • If you use a high concentration of vinegar instead of white vinegar, dilute it with water.
  • Ensure you apply vinegar on a sunny day to dry out the pesky weeds faster.
  • If it rains right after you have sprayed the vinegar, spray it again after it dries out.

Note:  Vinegar is the fastest and most effective way to kill weed due to the acitic acid. But safety should be a number priority; therefore, to keep yourself safe from toxic fumes, wear eye and face masks and gloves to prevent burns.
