Carefully release flowers from the water bag above the sink. Remove all the packaging and fill a vase with clear cold water. Add flower food and stir until completely dissolved. Cut the bottoms of all the stems at a 45-degree angle and put the bouquet in the vase with water and flower food. The flowers can stay in this water for 3-4 days. After that, the water has to be changed to fresh with flower food added.
For Dragonfly Floristic's 100roses bouquet, a large heavy vase with wide bottom or wide cylinder vase is the best. Do not squeeze the bottom of the bouquet, it will affect the shape of the bouquet in a bad way.
