Baking soda (sodium bicarbonate) is a surprisingly powerful ally in the garden. While commonly used in baking and cleaning, this humble white powder offers a wide range of gardening benefits—from enhancing blooms to deterring pests and preventing disease. Affordable, non-toxic, and effective, baking soda is a smart choice for gardeners looking for a natural approach to plant care.
How Baking Soda Supports Plant Blooming
Baking soda can affect blooming by adjusting soil pH. Many flowering plants prefer slightly alkaline conditions, and baking soda helps reduce soil acidity, improving nutrient absorption. This leads to more vibrant, healthy blooms. It can also serve as a gentle fungicide, protecting plants from diseases that might inhibit flowering.
