Overall, baking soda on plants had a beneficial effect in reducing the fungal spores.

2. Baking Soda Cleans Plant Leaves

You can do this by lightly wiping them with a sponge or cloth that is dampened with a diluted solution of water and baking soda. Add a half a teaspoon of baking soda to a liter of filtered water to make this gentle cleaning product.

3. Baking Soda is an excellent Weed Killer

To get in between the sidewalk cracks and spaces between pavers, use a whisk broom to sweep the powder into these hard to reach areas.

While baking soda can be a handy tool for natural gardening, you don’t want to rely upon it entirely. Like with any other natural ingredient, if it is overused, it will lose its efficiency. This is why you need to establish a schedule for sound garden management.
