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.
Magic #Oven Cleaning Method - If I had known it was this easy to get my disgusting dirty oven clean so fast and easy I would have cleaned it much sooner! I would also clean it every couple of months! Do your 5 minute prep the night before, wake up the next morning, wipe it clean and you are done! AWESOME!!
