"Weird but clever uses of white vinegar:
Extending the life of cut flowers

While white vinegar is a great w**d killer, it can also extend the life of cut flowers as it lowers the pH of the water.
The lower pH helps the flower absorb more water and creates a hostile environment for microbes.
Microbes, which are fed by decaying plant material and any added sugars, cut the life expectancy of flowers.
Sugar is important for any plants, as it’s high in carbs and continues to feed the flowers after they’re cut, helping unopened buds to open while extending the life and vitality of the open flowers.
Use equal parts of dissolved sugar and white vinegar to supply an adequate level of sucrose and acidify the water.
For a quart vase, use two tablespoons of each dissolved white sugar and white vinegar."
