When you receive your floral arrangement, it is important to keep it away from direct sun and heat.. Add warm water daily to keep green foam moist, or if stems of flowers are in water in a vase... add warm water to the vase. It is not necessary to pour the water out and add all new. Your florist has added a solution to the water to keep your arrangement fresh and help extend the life of your flowers, so you might enjoy them for at least 7 days. Extreme heat or cold is an enemy to your flowers! Enjoy the feeling a gift of flowers can bring!!!!!!!
