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.
Don’t worry about the grass and weeds growing into your beds.
This is a very old gardening trick that my grandmother taught me when we moved to our new house. Since she was born in 1917, you know it has been around for quite a while!
The baking soda will actually burn many of the weeds and grasses (including crabgrass) so they won’t even come back..
It can also help keep ants out of planters since they don’t like soil with high ph…sprinkle some baking soda around the base of planters to discourage them from coming up through the drainage holes..
Place a layer of mulch on top or sprinkle more baking powder if necessary after rain and watering
Just wanted to share this information with you all. It is very old and has been around for many years .
