So you decide to buy flowers from Beyond Blossoms.  They arrive on your doorstep in a secure box. Now what? How do you care for the arrangement you have just received? Water is vitally important when it comes to caring for your flowers. The first thing you should do is get your flowers in water. Although flowers are usually kept in the latent phase, due to refrigeration at flowers shops, once warmed to room temperature the flowers require water. They are alive and need a drink as soon as possible. You should water your flowers everyday, no matter how they are stored.
