What about these small packages of cellophane powders that come with flowers?
They contain a floral preservative which is a food agent, a moisturizing agent and an antibacterial treatment. When used properly, floral preservatives will considerably increase the life span of fresh cut flowers.
Food: The food provided by the preservative is a sugar. Plants produce sugar using photosynthesis from water, carbon dioxide and sunlight. When a flower is cut off from the plant, photosynthesis is no longer an option for sugar production. Sugar is needed to continue to develop the flower bud in a flower. With this sugar, the flower will have better results in terms of size, color and mud.
Hydration: Although cut flowers do not photosynthesize, they will sweat. This is to say that the water is still absorbed by the stems and discharged into the air through the stomata. A turgid flower is a hydrated flower. A wilted flower is one where the cells do not have their total amount of water. The outer ring of the stem of the flower, just under the bark, consists of tiny tubes or vessels. This group of vessels or vasculature is responsible for transporting water from roots, or vase in this situation, to leaves and flowers. The water sticks to itself and, in general, will tend to be stretched by the continuity of evaporation of water through the pores of the flower and leaves. However, when a flower has been dehydrated during the normal course of harvesting and shipping, the chemistry needs a boot. When the pH of a solution is more acidic, the molecules are more hydrophilic … or they tend to stay together. Thus, a good preservative includes an agent for lowering the pH of the solution, which promotes hydration. It is normally a mild acid such as citric acid.
Control bacteria: water in the vase or container can quickly become a bacterial soup. A few parasitic pieces of plant tissue and some latent bacteria are sufficient. Add preservative sugar and you have a recipe for cloudy and malodorous water. The problem is not only an aesthetic aspect. The bacteria in the water will form plugs in the stem of the flower, blocking the flow of water through the stem of the flower. A good floral preservative contains an antibacterial agent to prevent all this from happening.
Here's an ugly secret about these packages. Most packages are 5 gram packs that make a pint of solution. Most medium vases contain at least a quarter of water. If you do not follow the instructions to mix the vase solution and you get too weak a solution, you can provide enough sugar to develop bacteria while not supplying enough antibacterial agents to stop growth. This is a case where clear water with no preservative would be better than a poorly mixed solution. As soon as you notice that the water in your vase has begun to become cloudy, it is time to empty the water, rinse the stems, give them a clean cut and put them back into the vase cleaned with Of fresh water. This alone will double the life of your flowers.
Unfortunately, some flower distributors believe that the initial perception of the consumer is all that matters. They believe that the most important factor when choosing a preservative package to distribute with their flowers is the price. They will not spend the extra three to five cents to provide the 10gram package that should be provided. Instead, they believe that the consumer will be satisfied with any package as they know no better. This reduced sight vision means that the general perception of flowers by consumers is that they do not last as long as they should, and the water becomes dirty and smelly very quickly. In the long run, these consumers may turn to other gift ideas other than flowers, which harms the floral industry as a whole.
As a consumer, you must insist on the good conservative. This is worth the investment if you have to buy an extra package or two when you buy your flowers. You can double the life of your flowers!
