I have a half acre plot of Sweet Spot planted a year ago. Last Summer it established very well only to be invaded with Switchgrass the Roundup didn't take care of prior to planting. I mowed the plot in August and that took care of the problem (temporarily i'm guessing). The High Sugar Perennial Ryegrass came back strong as did the Winter White Clover. From the looks of this plot, i will need to mow again this summer to knock the Switchgrass and Foxtail down. When would be the best time to do that?
