How to stop weeds growing back on patio

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.

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.

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.

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.

Installing pavers results in spaces between the bricks or stones. The first step in preventing weeds is ensuring proper installation. A sand bed tightly packed provides a level foundation for the deck or patio. Once all the pavers are in place, additional sands should be packed into the crevices. This sand ensures each paver stays in place and helps prevent weed growth.

When weeds are already present you have to go from prevention to finding effective remedies for the problem. There are a number of ways you can remove existing weeds from your paver area. A single weed-removal method may not be enough. It may be more effective to combine two or more of these strategies, depending on how severe the weed problem is. Once the problem has been rectified, go back to the prevention methods to keep them away.

Proper Installation

Instead of treating weeds with harsh chemicals, open the pantry and reach for the white vinegar. Pour the vinegar into an empty spray bottle and spray the cracks between the pavers, leaving it to sit and work its way into the sand. When a few hours have passed, rinse away the vinegar with a garden hose. This simple remedy will kill the weeds without damaging the pavers or damaging nearby plants. Vinegar should not discolor pavers but if you have any concerns, do the same process with an inconspicuous test spot before treating the entire area.

Is It Too Late?

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.

You want to make sure you sand isn’t overflowing or any higher than the joints themselves. Now with your broom, sweep any excess sand in the joints as this just gives an even spread and also helps with the clean-up.

After the sanding is complete, it is advised to seal on the same day, so the sand works alongside the joints as soon as possible.
