I was on The Brick House blog this morning and they were showing their green weed killer that cost about $11. Reminds me of the time last summer that I spent the day on yard maintenance- I mowed, worked on the garden, pulled weeds, swept the sidewalks, and everything was perfect. I had some Roundup weed killer in my storage area so I decided to spray the spots where I pulled the weeds so they wouldn't return. The next day, there were burnt grass spots all over the place- it looked terrible the rest of the summer. Lesson learned- no more toxic weed killer ever.
