which all helps increase longevity of cut flowers when harvested. When flowers are harvested they are rapidly cooled and held at 33*. They are then treated with Siver Thiosulfate, which is a compound of silver, an antedote to Ethylene (an odorless gaseous hormone that stimulates aging and consequently premature wilting of fresh flowers). The harvesting process takes days to complete. Cut flowers are then shipped to suppliers all over the world where they then recut dry packed cut flowers and hydrate them with an acidifier that opens up the stem capillaries and aids in the immediate uptake of water and sucrose. After a few hours these specially treated flowers arrive at A&J's where each stem and bud is cleaned, recut under water, ( water quality influences flower quality. Flouride, salts, and alkalinity effect vase-life. FIltered or bottled water is best, softened water is detrimental. Tap water is okay) and rehydrated with high levels of  preservative. 

Fresh flowers are recut 1/2-1" off the bottom of stem on a slant so they do not adhere to the bottom of a vase as they heal (this should be done daily) Woody stemmed botanicals like lilac, cherry, forsythia, etc. should never be crushed, this inhibits water uptake. Removing bark to the green part of the stem is best. At this time a preservative is administered to all botanicals. It is a compound of sucrose to keep the flower fed, a biocide that kills bacteria to keep it healthy, and an acidifier that literally males water wetter so that the stem continues to provide water to the flower bud and promote opening. Fresh flowers are then held in refridgeration of 33-40* for optimum freshness. From Grower, to Supplier, to the Florist, the care and handling each is responsible for is imperative  in the chain of life of a cut flower and affects the vase-life or longevity. When treated properly all flowers should last at least a week, some varieties much longer.

When fresh flowers arrive to the consumer, they should continue the same processes that promote floral health. Recutting stems under water on a slant, using preservative as directed, and providing fresh water daily. Keep flowers cool.
