Broadleaf weeds, such as dandelions, spurge, or creeping Charlie may require the use of a broadleaf herbicide or plant killer. However, the first step in any lawn weed control program is to maintain a thick turf that can choke out most weed problems.
CausesIncreasing numbers of weeds are often the result of poor grass growth. Causes include:
Using herbicides to eliminate weeds without adjusting lawn care practices won't correct the problem.
Cultural ControlsIf only a few weedy plants are present, dig or cut them out. For example, continued removal of dandelion tops eventually reduces reserves in the taproot. The plant will no longer regrow.
If herbicide is needed, be sure the selected product is labeled for the weeds to be controlled. Follow the directions and heed statements about safety to grass, surrounding plants, your health and the environment.
