how to get rid of weeds growing between concrete

If you have cracks or gaps that you can’t or don’t want to seal, you can go salted-earth on them – literally. Plants can’t tolerate salt well at all. That’s why “salting the earth” was an army tactic hundreds of years ago: it kept people from growing food on that land in the future.

Do you have some weeds that seem to come back no matter what? You might need to fight them with fire. A small propane torch can be effective at spot-removing weeds in stone patios, driveways, or sidewalks.

After all, weeds are only a problem because they’re so good at growing where they shouldn’t. They pop up in the most inconvenient places – the middle or your garden, throughout your yard, and worst of all, between slabs in your driveway or sidewalk.

You can use this to your advantage in your war on weeds. Make a hot salt-water solution of one part salt to nine parts water, and pour it into the cracks and gaps where weeds live. This will soak in and remove your weeds over time. Just make sure none of your salt water runs off into gardens or your lawn. It will harm those plants, too! That’s why it’s important to be careful salting your sidewalks in the winter.

If you have many weeds, or if you have garden tools on hand, using a V-notch weeder can make things easier. These tools use a special notched design to pull weeds more effectively.

Keeping your home looking well-groomed means getting rid of these problem plants. Luckily, there are strategies to help you remove weeds between slabs, as well as methods to keep them from growing back.

Finally, if nothing else has worked, you can use heavy-duty weed removers. There are several weed removers that linger for months or years where they’re sprayed. “Extended release” or “year-long” guarantees are a good clue that you have something that will stick around.

Successful weed control begins with knowing your foe's likes and dislikes and habits. In their own way, weeds are marvels of genetic evolution. s

You can stay on top of weed control by devoting a bit of time to the job each week. Many homeowners like to conclude weekly mowing or garden work with a few minutes spent plucking or killing the weeds sprouting out the pavement cracks around the landscape.

Before Getting Started

Grasses and weeds growing out of pavement cracks in sidewalks, driveways, and patios is a common annoyance. Sometimes it seems as though these unwanted plants grow even better in tiny pavement crevices than they do in the lawn and garden. This defies all logic since pavement surfaces are brutally hot and dry places where you might think that nothing could survive. But not only do these tenacious grasses and weeds survive, they alsoseem to positively thrive in this no man’s land of blistering hot pavement.

You will quickly recognize that various weeds have their favorite seasons, and are vulnerable to different control methods. The damp spring might be best suited to plucking weeds by hand, while during the dry months of late summer, chemical herbicides might be the better strategy.

Thanks to this genetic tenacity, grasses and broadleaf weeds that sprout up through the cracks in the pavement are very hard to control. It is easy enough to pluck the top off at pavement level or sever them with a string trimmer, but unless you extract or kill the entire root, the plant often simply sprouts up again.

In cold weather, a dark-colored asphalt driveway absorbs sunlight and keeps the soil beneath warmer than the surrounding landscape. Some grasses and weeds can easily tolerate the salts in ice-melt products. Fescue, for instance, is a cool-season grass that is somewhat salt-tolerant and might have a good chance of surviving through the winter in a driveway. Sedge is a grass relative that tends to stay green in winter. And then there are the cold-happy weeds such as chickweed that seem to scoff at temperatures at which other plants would have long disappeared.
