What is the flower saver powder made of ?
Short answer: Bactericide, acidic additive and sugar



Long answer:

The function of a floral preservative is to lengthen the life of a cut flower. There are many commercially prepared floral preservatives such as Floralife, Bloomlife, Petallife, Roselife, Everbloom and S-O Preservative. Floral preservatives generally contain a sugar, a bactericide, and something to make the water acidic. They usually come as a measured amount of powder in a small packet, designed to put into a quart of water.



Sugar is included to provide a good energy source for the flower. The final sugar concentration in the water mixed with the floral preservative is usually in the range of 1/2 to 2%.



Unfortunately, sugar is also a good energy source for undesirable bacteria and fungi to grow in the water. These can build up in the water and clog the water-conducting vessels in the flower, which shortens its life. For this reason a bactericide must be included in a floral preservative. One of the more common bactericides is called 8-HQS although a chlorine compound may also work well. It is important to use a substance that prevents the growth of bacteria but is not toxic to the plant.



Floral preservatives also include something that will make the water more acidic. Acidic water discourages the growth of microorganisms and helps to increase the life of the flowers.
