21 July 2008 (Re-started December 2007)
Plot D was first dominated by white sweet clover with patches of wild radish. By May white sweet clover was mostly gone and ragweed was dominant. By mid June patches of lamb's-quarters were taller than the ragweed, but by the time these pictures were taken the ragweed had equaled or overtopped the lamb's-quarters and the plot looked like a nearly pure stand of ragweed.
