Hand pulling or using an appropriate weeding tool are the primary means of mechanical weed control in lawns. This is a viable option at the beginning of an infestation and when weeds are young. Hand pulling when the soil is moist makes the task easier. Weeds with taproots like dandelions or have a basal rosette (leaves clustered close to the ground), like plantain, are easier to pull than weeds such as Bermudagrass (wiregrass) or creeping Charlie (ground ivy) that spread with stolons or creeping stems that root along the ground.
