Turns out that vinegar is a jack-of-all-trades.  Not only can you cook with it, it's an effective window cleaner, disinfectant, stain remover and has the ability to help control weeds. Here's what you need to know to effectively use vinegar as a weed-killer in your yard. Typical white vinegar in the store is 5% vinegar (acetic acid) and 95% water, which works best on small, annual weeds that are less than two weeks old. You can up its efficacy by adding a cup of table salt and a tablespoon of liquid dish soap to a gallon of white vinegar. Usually, this mixture only kills the tops of the target weeds, leaving the roots that can regrow new shoots. And be aware that salt build-up in the soil from repeatedly using this homemade solution can mean nothing will grow in that area at all. To get rid of tough, perennial weeds, a 20% vinegar solution is best. This type of vinegar, sometimes called horticultural vinegar, can be found at garden centers, farm stores, or online. Vinegar is non-selective, meaning it will damage any plants and turf grass it touches, not just the weeds you are trying to kill. The safest places to use vinegar on weeds is in between concrete seams in sidewalks, mulch or gravel paths, and driveways. It's usually easy to spray the vinegar in these areas without getting it on other plants. As with any weed killer, select a day that is warm and sunny to apply it. Avoid days that are windy or rainy. Wind can carry the vinegar to places you don't want it. Rain weakens it, diluting its effectiveness. For a couple of days after applying the vinegar, you can expect the area to smell like a salad dressing exploded all over your yard. On the plus side, that powerful scent can persuade deer, rabbits, and other pesky critters to steer clear of your garden for a while. Wait at least two weeks before spraying again.
