Adding sugar to your flower water is not the best practice for most household flowers. Instead, a pinch of sugar can sometimes be beneficial as it feeds the bacteria in the water, but doing so without balancing with an acidic agent like lemon juice or an aspirin to prevent bacterial growth could do more harm than good. For best results, use preservatives designed for cut flowers or simple, clean water changed every two days.
