use if baking soda

Question

how often can I spray baking soda on balcony garden plants?

Answer 1

I would do this very sparingly, as sodium can be toxic to plants if used too often. Most of the time, neem oil is a better choice as this can solve many issues that sodium bicarbonate can be used for.
