Are dandelions sprouting up in the cracks of your driveway or along the fringes of your patio? Make them disappear for good by spraying them with full-strength white or apple cider vinegar. Early in the season, give each plant a single spritz of vinegar in its midsection, or in the middle of the flower before the plants go to seed. Aim another shot near the stem at ground level so the vinegar can soak down to the roots. Keep an eye on the weather, though; if it rains the next day, you’ll need to give the weeds another spraying.
