Fresh-cut stems are still alive. They respire, release moisture, and respond to ethylene until they are placed in a controlled environment. For florists and perishable-goods operators, cold storage is not simply about making a room cold. It is about controlling temperature, humidity, airflow, and product compatibility so that stems, foliage, and adjacent perishable inventory move through receiving, design, display, and delivery without losing salable value. Temperature and Humidity Control for Cut Stems Most general cut-flower handling guidance places storage between 33°F and 38°F, while tropical flowers often require warmer conditions depending on species [1][3]. The goal is to slow respiration without freezing delicate tissue or causing petal damage. In mixed-use areas where florals are held
