Weed-free lawns are the stuff of dreams and championship golf courses. In fact, when you consider the tenacity of weeds, it's a wonder any of us win the pitched battles we wage with these pesky invaders. Just one dandelion plant makes up to 15,000 seeds, each of which can survive six years in the soil—creating 15,000 more seeds when it sprouts and matures.
The best way to control dandelions and other weeds in your yard is to grow a thick, vigorous lawn. Dense grass crowds out weeds and blocks the sunlight their seeds need to germinate. If only a few weeds dot your lawn, changing your maintenance tactics might be all it takes to get rid of them. And if your efforts at hand-to-hand combat haven't worked, take heart. There really is a way to pull out even stubborn dandelions so they don't come back.
