To get a nice clean clover plot this fall, you need to maintain it during the summer. One step is to spray a grass selective herbicide if the grass competion is strong. You should mow it in late spring to control broadleaf weeds.

Hi Bill,  When starting a plow down clover or any clover plot when and with what herbicides should I spray out competing grasses and broad leaves? I’ve got really good germination I’m just noticing since we’ve got several days of rain that the grasses are starting to make a big jump as well can I spray now while the clovers are coming up or wait until they get a couple inches tall?

Bill responds,

Generally, you want the weeds to be growing very quickly when you spray so that you get a good kill. If the soil temperature is a bit cold, the weeds will slow down their growth and that will reduce the quality of your kill. With that in mind, you should probably wait just a bit longer, maybe two more weeks. Clethodim is best for killing grass in clover and alfalfa, comes in many brand names like Arrow 2EC and Dakota.

You can normally wait until late spring to mow it to remove broadleaf weeds from clover. Unless they are really bad, you generally don’t have to spray them. If that is the case then Imox is a good option.  Good luck
