Does room temperature or light affect my flowers?- Flowers 101

Absolutely, temperature and light will affect the amount of water your flowers drink. Setting your flowers in the sun or in a hot room with a ceiling fan or near a heat or air source will cause the flowers to evaporate water off the bloom faster and in some cases faster than they can suck it up their stems. Keeping flowers in a cool, shaded area away from breezes or drafts is best!

Light will help closed flowers open faster. The more they are exposed to light (even bright, indirect light helps) the faster they will open. To keep flowers closed, putting them in a dark, cool room (a basement) is helpful.
