Overgrown broad leaf weeds in the yard.

When is the best time to treat broadleaf weeds?

Controlling broadleaf weeds such as ground ivy, dandelion and white clover weeds in the lawn is best done in October.

 

Fall is the ideal time because unlike the summer when weeds are focusing on top-growth, in the fall weeds are storing energy in their root system and are more susceptible to herbicide applications, it’ll make a difference in what you battle next year.

 

Michigan State University Extension recommends applying the herbicides on a sunny day when rain is not in the forecast for 24 hours, so the herbicides dry on the leaf surfaces and not washed off.

There are many different herbicides that could be used including the most common three-way broadleaf weed control mixtures. Just follow the manufacturer’s instructions.
