Freshly cut flowers will last longer if you add 1/4 teaspoon bleach per quart (1 liter) of vase water. Another popular recipe calls for 3 drops bleach and 1 teaspoon sugar in 1 quart (1 liter) water. This will also keep the water from getting cloudy and inhibit the growth of bacteria.

To store the flowers properly, fill a vase about ¾ full with water, and then put the flowers in the vase. Set your refrigerator's temperature to 40 F and remove all fruit from the refrigerator. (They give off gases that could decay the flowers.)

Any of the fungicide products (bleach, baking soda, vodka) combined with soda or sugar and some form of acid do a good job of keeping flowers fresh.

While the ingredients vary depending on the manufacturer, most contain sugar to feed the flowers, acid to maintain the pH levels of the water, and a bit of bleach to reduce the bacteria and fungi in the vase water. All three help extend the life of the flowers.

The vinegar helps inhibit the growth of bacteria and keeps your flowers fresher longer. If you don't have vinegar and/or sugar, lemon-lime soda mixed with the water will do the same thing.

Sugar increases fresh weight of the flowers and prolongs the vase life. Use 0.5 - 1% Floralife (concentration of sugar not specified). 2% sugar solution doubles the vase life of the cut inflorescence. Some sugar in the vase solution increases the number and size of open flowers as well as prolongs the vase life.

Keep flowers as cool as possible, but avoid putting them in your fridge, if you can. Florists' coolers range from 33° to 40°F, so your fridge likely won't be cool enough and any fruit or vegetables could emit ethylene gas, which shortens the life of cut flowers.

Both sugar and bleach help flowers stay fresh. Sugar gives them nutrients they need that aren't found in water, while bleach keeps the water clean and kills bacteria that causes flowers to wilt faster. However, too much of each can cause the flower to die faster than if you didn't add anything to the water.

Sugar increases fresh weight of the flowers and prolongs the vase life. Use 0.5 - 1% Floralife (concentration of sugar not specified). 2% sugar solution doubles the vase life of the cut inflorescence.
