Mechanical Damage

Avoid bruising and breaking cut flowers which reduces their aesthetic value and, thus, their wholesale/retail value. Pathogens (disease organisms) may gain access through wounded areas and, thus, further decrease their value. Ethylene production and respiration are both natural wound responses. These two reactions greatly accelerate in response to mechanical damage and, thus, shorten postharvest life.

 Diseases

Flowers and foliage packed moist after harvest are very susceptible to a number of disease organisms. Condensation of water on the flowers or foliage encourages diseases. Avoid moving flowers directly from cool to warm rooms which results in water droplets forming. Botrytis (gray mold) is the most common disease wherever excessive moisture occurs.
Although botrytis can be controlled by fungicides, proper environmental management is the best method. Reduce excessive humidity and do not allow water to sit on the flowers and foliage.

Insects

Insect damage is rarely encountered as long as refrigeration is provided. However, insect damage during production reduces quality and provides entry points for diseases. Cut Flower Storage/Display Facilities A number of quality flower coolers are commercially available today. Choose a model that fits your needs and also controls critical environmental factors, mentioned earlier, as closely as possible.
When choosing a cooler look for one that not only will provide proper environmental needs, but also will help market the flowers. In other words, purchase a cooler that is functional and attractive. One major purchase decision is whether to buy an enclosed or open-air flower cooler. An enclosed cooler controls temperature and humidity to near ideal conditions, allowing for prolonged cut flower storage. An open-air cooler will not maintain the favorable conditions as well as an enclosed cooler but is preferred for customer convenience.
Open air coolers tend to be more inviting for customers to visit, and are especially appropriate in businesses with rapid turnover of floral stock. When feasible, choose a triple pane glass or heated glass floral cooler. During hot and humid weather in Oklahoma, condensation can form easily on cool, thin glass, thus blocking  the consumers’ view of flowers. Insulation of three to four inches is also advisable for energy efficient use. Avoid placing the cooler in direct sunlight, for further energy savings.
Newer models control ethylene with filters that can be placed inside. One additional feature to consider is the dual temperature controls, for allowing storage of temperate and tropical flowers at the same time.
Growers/marketers should contact their local cooler manufacturer for assistance in building a cooler. Not only will suppliers be eager to sell parts and offer maintenance, but some can assist with engineering skills and advice in the construction of the cooler.
