Answer: Once cut, flowers can't handle being in sun, prefering dispersed light, preferably in a cool location. Here are a few pointers for cut flower preservation:
1. Harvest just before the flower peaks.
2. Harvest in the morning, if possible.
3. Use a sharp tool to make a clean, slanted cut.
4. Immediately place stems in water.
5. Recut stems under water just before you arrange them in a vase.
6. Keep flowers in a cool area, but not in drafts.
7. Use a floral preservative, or make your own with 1 pint of regular 7-Up or Sprite (not diet) mixed with an equal volume of water with a teaspoon of household bleach, OR 1 quart of water with 2 tablespoons of fresh lemon or lime juice, 1 tablespoon of sugar and one tablespoon of household bleach.
8. Use warm water in the vase.
I hope this info helps!
