The nightmare of dandelions is the deep taproot (up to 15 feet long) and puffball seedhead, which disperses seeds on every breeze. The best defense against dandelions in the lawn is growing thick, healthy turf, which means mowing at the right height and fertilizing correctly. In planting beds and paths, these familiar weeds tend to show up in the worst places, such as rooted in the center of a perennial clump or tucked right in the edge row of paving stones. The best ways to get rid of dandelions? Spray them or dig them. When spraying, kick dandelions a bit first to scuff and wound the leaves—it helps the spray penetrate better. With digging, make sure you get at least 2 inches of taproot or they’ll return as two plants.
