To control clover which has already established itself in your lawn, a post-emergent herbicide that is specifically designed to handle broadleaf weeds like clover is essential. Examples include formulations containing chemicals such as 2,4-D, dicamba, MCPP, or triclopyr. Always follow the label directions for the best outcome.

Here’s a natural weed killer recipe many gardeners find effective: Mix vinegar with a small amount of dish soap, put the mixture in a spray bottle, and spot treat clover clumps. Just take care to avoid surrounding plants.
