Aspirin doesn't work.


"Experimentation shows this method doesn't work well."

Aspirin, in fact, had an adverse affect. The flowers appeared unhealthy, were wilted, brownish, and very dry.The aspirin solution may have been pulling the water from the cells of the plant. Since we observed the stems of the Aspirin group becoming brown, it is possible that the cells were drying out and dying.

Keep your arrangement out of the sun.


It'll last longer if not overheated, away from bright lights, %26amp; out of drafts. A cooler area is better.Keep the water clean by changing it every couple of days so bacteria doesn't make it rot. Remove any lower leaves that would otherwise be immersed under water as they will rot and shorten the life of your flowers


Some people even add a drop of bleach to the water.





"Suggestions range from adding a few drops of bleach to each pint of vase water to keep bacteria from growing to using a solution made with lemon-lime soda, one part soda to two parts water. The sugar in the soda is said to feed the flowers and help buds continue to open, and acidity inhibits bacterial growth."

Michael Skaff, a floral specialist for ftd.com recommends: "Under running tap water, quickly cut the bottom of the stems on an angle and remove foliage that will be lower than the water level in the vase. Then add two to three drops of bleach to the vase to prevent bacteria buildup. "

BTW, The ingredients in commercial flower food which keeps flowers fresh for at least a full week helps reduce the concentration of bacteria in the water, keep the water acidic, and supplies the flowers with sugar.





Good luck! Hope this helps.
