In addition to biocides, the pH of the water should be acidified to 3.0 – 5.5 as researchers have demonstrated that flowers absorb more water in acidic solutions than those at higher pH levels. Assoc. Flower stems naturally bend away from gravity and this phenomenon is called geotropism. Hydrating solutions are used immediately after harvest and are usually used for a short time, for example four hours. we are dealing with the physiology of senescence and the post harvest handling of cut flowers. during welding. The next level of improving postharvest care would be to include a biocide such as a solution of 50 ppm bleach (mix three quarter teaspoon of bleach to 1 gallon of water) or preferable slow release chlorine tablets and an acidifier to acidify the water to pH 3.5 to 5.0. place the stems in warm water and allow the water to reach ambient temperature gradually.
