Regular sealing will keep those determined weed seeds from taking hold between your pavers.
Is there a way to prevent them from sprouting in the first place?
Which brings us to.
We have your weed-free answers, step by step.
Step 5: If You’re Planning A New Patio
Here at Outback Landscape, we have the skills, tools and knowledge to design and install patios that stand the test of time — and stand up to tenacious weeds.
That’s right. A flat-topped screwdriver works great to pop pesky weeds out by the roots. If you just grab a weed by the stem, you might get the top part of the weed, but the roots will remain. That weed will grow back faster than you can say “Roundup.”
This spray-on weed killer kills existing weeds and keeps new ones from sprouting for up to a year. It’s a great way to keep weeds from growing between pavers.
Step 1: Grab Your Screwdriver
We recommend sealing your paver patio at least every two or three years. Do it every year if you really want a nice, weed-free surface.
If weeds sneak through — and the pesky things do — we can remove them, so you can go back to enjoying your weed-free patio.
Pressure washing the whole patio is a dual-purpose solution. Not only will it remove the weeds from the spaces between the pavers, but it will also provide a deep cleaning to the pavers, making the whole area look like new again. If you are pressure washing, do not simply use a jet nozzle. The water pressure from the nozzle can wash away the sand between the grooves and etch the surface of the pavers themselves. Instead, use a rotating surface cleaner attachment in tandem with the pressure washer.
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.
Once you remove the weeds through one of the methods mentioned above, stabilizing sand can be used to help keep any roots from growing back. When adding sand, it is essential that the patio is dry and free of weeds. Some paver sands feature gel additives that react with water, filling in the space between the stones so weeds have nowhere to go. Some sands also feature a pH that inhibits weed growth by making it uninhabitable. The type of sand used will help to determine the proper installation method. Follow the instructions carefully to ensure the product is used properly.
Weeds thrive in cool, damp soil. When the deck or patio is properly sloped, water runs down the slope and doesn’t stay stagnant in the crevices between the pavers, helping to prevent the conditions weeds need to thrive. The slope of the paved area should always tilt away from the house.
An alternative to hand-pulling weeds is taking advantage of a mechanical removal solution. Crack scrapers are outfitted with L-shaped blades that pull a weed from the stem, removing the weed at the base of the stem. Normally, this method leaves behind the root, allowing for regrowth. As a result, mechanical removal is a way to temporarily restore the look of the deck or patio, but future mechanical removal sessions will be needed to remove regrowth.
Is It Too Late?
Most of the time, weeds to not sprout up from beneath the pavers. They actually start with seeds that settle between the cracks of the pavers on the surface. Seeds need to take root in order to grow. Sweeping your pavers regularly will disrupt the seeds prior to rooting, helping to inhibit weed growth. Sweeping also removes surface dirt and helps to enhance curb appeal by keeping your pavers looking clean.
