Whether you've just noticed that weeds are choking out your garden or you want to stop them from sprouting between the cracks in your driveway once and for all, there are plenty of options available that don't cost a fortune. If the solutions you've tried in the past have failed to work, keep reading below for some tried and true methods that are guaranteed to get rid of pesky weeds.
Bleach is a simple way to get rid of weeds that are growing in your driveway cracks. Pour some bleach along the cracks and then wait a few days for the bleach to act. Then pull the weeds out by hand, or better yet, scrape them out using a long, sharp tool such as a screwdriver. Be careful though that you don't accidentally pour any bleach on nearby grass or other plants that you actually want to keep healthy.
If you don't have any bleach on hand, don't worry. A bottle or two of apple cider vinegar will work just as well. As with bleach, pour the vinegar into the cracks of your driveway and wait a few days until you see results. That said, make sure that you do it during a week in which you know it won't rain. One light storm and you'll be forced to reapply the vinegar if you want to see good results.
If you've got some more ground to cover, there's nothing better than fire. Of course, this is a method that requires a little more caution than others, but as long as you aren't setting piles of dry grass on fire, you'll be just fine. For smaller weeds, a butane lighter will work effectively to remove all the moisture from the weeds and reduce them to withered stems within minutes. Larger weeds may require a weed burner (sometimes called a scorcher or torch). These utilize the same principle, but are powered by propane.
If you don't have a garden yet and are looking to plan ahead for the planting season, then purchase a large, thin plastic sheet that you can use to cover a garden bed. Dig a trench around the bed and bury the edges of the plastic sheet in the trench with a layer of topsoil. Assuming you've already cleared out the soil underneath, there's no hope of weeds sprouting up under the plastic and contaminating your new garden.
