Killing Giant Horsetail – My Giant Nightmare

May 27, 2009

I am posting this entry out of pure selfishness. I am hoping that someone can help. We installed new landscape a few years ago. A designer from a local nursery recommended giant horsetail for one area of my yard. She swore up and down that the expensive chemical Bio Barrier would keep it from spreading into the rest of my yard. WRONG!!! It’s everywhere. I was just too naive at the time to question her. It was my first ever experience with a yard full of real live plants.

I can’t keep it under control. I’ve tried RoundUp, digging it up, Remuda, Brush B Gone and a few other things and it’s not helping. I’ve read about liming but the San Diego City Weed Expert (I can’t remember his real title) said there is already a lot of lime in our water and that I shouldn’t do that. His answer was to cut off the top of each new stalk, and shoot a syringe full of Brush B Gone down the center of it. Well, I’d be out there every day for multiple hours if I followed his advice. I did try it but with no success.

Any ideas?
