Cut flowers should be plunked immediately into water until they can be arranged. Then consider these tips, though not scientific, from several flower arrangers.
The Two Main Causes for Cut Flowers Wilting
Air bubbles in the stem’s transport tubules, and fungi and bacteria in the water. Change the water every few days and recut the stems under water. Remove leaves which will be under water helps prevent mushy, smelly decay. A few drops of chloral may retard fungus. Floralite (a product available from many florists) has some of these and plant hormones that also may help.
A bit of sugar added to the water supposedly helps the buds open and may provide an energy source for the flowers. Keep flowers away from heat sources (like on top of the TV), out of direct sunlight and also prevent them from freezing. Most last longer in a cool place. Some flowers are programmed genetically to last longer than others. Among the longest lasting ones are miniature carnations and chrysanthemums.
Much has been written about these because they wilt so quickly and the buds fail to open. For best results with roses, plunge them into water as soon as possible. To arrange them, make a new cut in the stem at an angle, ideally under water to prevent air getting into the fresh cut. Use lukewarm water immediately after making the fresh cut. When the roses stiffen up, change to cool water. Floralite is recommended. With luck …
