Baking soda neutralizes the ph in the soil and nothing will grow there. use baking soda around all of the edges of flower beds to keep the grass and weeds from growing into beds. Just sprinkle it onto the soil so that it covers it lightly. Do this twice a year - spring and fall.
Was Glad to find this. I had previously pinned one that used a lot of bleach and wanted to avoid that. Here's a great one that only uses vinegar and baking soda. My washer is now nice and clean! Altho it was no where near as dirty as the one shown in the blog.
