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.
Vertical gardening - it maximizes your harvest, makes the most of limited space, doesn't require lots of bending, and keeps your veggies away from pests and rot. This easy-to-assemble kit lets you grow vertically vining plants either against a wall, or as a free-standing unit using your own posts. Takes up just four square feet of growing space but produces more vegetation than a 24 square foot plot! Perfect for tomatoes, pole beans, cucumbers, or any vining plants.
