Answer: Here's a technique and two recipes to try: cut your flowers early in the morning when they're freshest and put them into a container of water immediately after cutting. When you get inside, mix 1 teaspoon of chlorine bleach and 2 tablespoons of sugar into one gallon of water. Use this water in your vase, and change the water every three days. The acid slows bacterial growth and the sugar provides nutrients. Or, you can mix 1 cup of clear lemon-lime soda (like 7-Up) into one-half gallon of water and use it to fill your vase. Either of these techniques works well. If you re-cut the stems every time you change the water, you'll prolong the bloom even more.
