Could anyone describe what Round-up like conditions are? I did search
the archives but didn't find much. What about Subdue or Diuron use on iris?
Weeds and grasses seem like a terrible invasion of my iris beds until I read the
posts about borers! YUK! I've put in several new raised beds that are clean (so
far!) but the older established beds are a constant battle. Considering
chemicals and would like some ideas.
Thanks for any info.
