Organic weed control for dandelions

Spring and summer often find homeowners out in their yards, busily attempting to control the onslaught of dandelions in a quest for green, weed-free lawns. Responding to criticism that synthetic herbicides can be harmful to the environment, researchers around the world are experimenting with organically derived weed control methods. Researchers recently studied the effectiveness of pesticide-free mulched maple and oak leaves on common dandelions in established Kentucky bluegrass comparable to residential lawns.
