5. Discourage Weed Growth


No one enjoys battling weeds in their garden. Weeds suck vital nutrients from your plants, or they can make your landscape look like a jungle. Try pouring baking soda into the cracks in your sidewalk or patio. Apply baking soda in your garden to those pesky weeds. Doing so will kill off weeds and stop others from growing.

6. Sweeten Up Your Tomatoes


A creative way to use baking soda is to use it to sweeten up your tomatoes if you prefer sweet tomatoes. All you need to do is sprinkle baking soda on the soil around your plants. Make sure you aren’t sprinkling the baking soda on the actual plants. It works by lowering the acidity level of the soil, which will lower the acid in the actual tomato fruits.
