How do I keep online delivered flowers fresh longer? To keep delivered flowers fresh for longer, cut the bottom of the stems at a 45-degree angle under water and put them in clean water. Sai Flower says keeping flowers away from direct sunlight, cold air from air conditioners, and ripening fruits can make them stay fresh for up to seven days.
