From the lovely but now retired blog of Beth Evans Ramos. This was a picture she snapped on the Georgetown Garden Walk in 2011. These are tincan lids used as siding on a chicken coop! She has a new website, Mama Knows Her Cocktails and she is also now on Pinterst!
Baking soda neutralizes the ph in the soil and nothing will grow there. I use baking soda in a 6" wide area around all of the edges of my flower beds to keep the grass and weeds from growing into my beds. Just sprinkle it onto the soil so that it covers it lightly. I usually have to do this twice a year - spring and fall.
