Do brown sugar and baking soda really help plants grow?
Solution: A mix of brown sugar and baking soda provides quick energy to soil microbes and balances soil pH, helping plants absorb nutrients better. Brown sugar is sometimes used to supplement soil microbe health. Vinegar can be useful to amend water pH if its too high, but could cause toxicity if the soil is high in elemental aluminium.
Do sugar and vinegar help plants?
The sugar helps feed the flowers the right nutrients to survive longer even after they are cut. The vinegar keeps the pH of the flowers balanced, preserving and prolonging their lifespan. In this sense, sugar within the water can temporarily help the plant keep growing, like to unfold a tight flower bud, but it’s usually only enough food to finish blooming before the flower starts to decay.
