Irish Moss vs. lawn grass along my water garden, near Seattle

July 4, 2009 - 12:32 am
  • I have lots of nice, pretty Irish Moss (Sagina Subulata) growing around my water garden but there is a bit of lawn grass sprouting in the moss. There's too much grass to pull by hand. I'm looking for some kind of effective process or chemical/grass killer that will kill the grass without harming the moss.


  • Greetings alias... I finally got hold of the very knowledgable staff at the local Green Thumb store. The gentleman I spoke with suggested a chemical I had found info on already. His suggestion was a confirmation of the herbicide: Fluazifop-P-Butyl [ http://tncweeds.ucdavis.edu/products/handbook/fluazif.pdf ] He said browning may occur with use. Test in a small inconspicuous area. It will spring back very readily though. It is best to spot apply to avoid any problems. You can apply by dripping on grassy outcroppings, spraying with a low mist sprayer or painting on the leaves with a brush. If you really must broadcast the herbicide, it might be prudent to dilute. -Search Techniques- Googled: annual perennial grass control postemergent [ ://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&q=annual+perennial+grass+control+postemergent ] Called: Green Thumb Nursuries Good luck with your Sagina Subulata ;o) -AI


  • Hi again alias... I thought I would add the common off the shelf names for this chemical. Fluazifop-p-Butyl can be found as Fertilome Over-the-Top Weed & Grass Killer, Fusilade DX , Fusion , and Tornado Here are some references: [ http://tncweeds.ucdavis.edu/products/handbook/htable.pdf ] [ http://www.conservation.state.mo.us/nathis/exotic/vegman/three.htm ] [ http://www.hcs.ohio-state.edu/hcs/webgarden/Land/LAND_Aug97 ] -AI
