purslane must die
The yard surrounding the house we bought was in pretty poor shape a few years ago. Pocked with dry spots, an irrigation system that needed attention, and weeds. Most annoyingly is purslane. With it's itty bitty seeds and ability to live in nearly every condition.
We spent the better part of a weekend pulling and filling the equivalent of 95 gallons of this cruel plant. I spent hours online trying to find an environmentally-friendly solution. I even called a Boulder County organic lawn service and asked them. They told me 'we'll get right back to you', but i didn't hear a thing.
I have found one product that kills purslane: Ortho® Weed-B-Gon MAX® Weed Killer For Lawns Concentrate. Having looked all over online, I came across a few research papers pointing to the active ingredient Dicamba.
Up next: Ortho has done it again, with Ortho® Grass-B-Gon® Garden Grass Killer. My lawn's Bermuda will soon become extinct.
UPDATE: Yes, a few of you are bright and tell me that these creatures can be eaten in a salad. Fine. Come and get yours. I'm not one to enjoy the bliss that is chemically treated gardens, but desperate times call for desperate measures.
