RAW flowers are carried with a biodegradable cloth to keep them hydrated. As soon as you receive them, some stems may be dehydrated (you can recognize it by the soft stem), cut the stems by 2/3 cm, choose a clean vase, fill it with fresh water [in summer it is better to put a little water, 3/4 fingers and change it every day] and eliminate the leaves that could come into contact with water to fight the proliferation of bacteria. To give the flowers room to shine, untie the bouquet.
