Killing dandelions and other weeds — If you had dandelions, chickweed, clover and/or henbit go to seed in your yard earlier this year, chances are new plants will be germinating from the seeds this fall. Now into early November is the best time to control such broadleaf weeds. The plants will probably continue to germinate into early November, so waiting as long as you can will help you kill more of the weeds, extension agent Rebecca McMahon said. But you also have to keep an eye on the weather, because it has to be warm enough for the plants to take the poison to the roots. And you have to treat on a day that is above 50 degrees. Use an herbicide such as 2,4-D or combination products Trimec, Weed-B-Gon and Weed-Out that contain 2,4-D, MCPP and Dicamba. If the temperature is on the colder side when you treat, Weed Free Zone (also sold under the name of Speed Zone) will work better.
