If you have only one cooler, you may be tempted to store cut flowers and produce together. Often you can do so without problems, but you need to keep in mind two factors: best storage temperatures and ethylene sensitivity. Chain of Life Network offers these guidelines:
    Crops that store and ship best at 31-35°F include apple, cherry, grape, pear, strawberry, asparagus, cabbage, lettuce, carrot, rose, chrysanthemum, snapdragon, carnation, azalea, hydrangea, tulip, narcissus, alstroemeria, ageratum, marigold, cyclamen, delphinium, lily, gypsophila, and statice.
    Crops that store/ship best at 50-60°F (10-16C) include sweet potato, cucumber, eggplant, pepper, tomato, most foliage plants, African violet, gloxinia, poinsettia, anthurium, ginger, begonia, most orchids, and streptocarpus.
    The above information does not mean that all crops within one temperature compatibility group can be stored/shipped together, as there are ethylene sensitivity reasons that would preclude their mixing.  What these groupings do tell us is that crops that do best at 31-35F should never be held with crops that do best at 50-60F and vice versa.
    Crops that can produce high amounts of ethylene include apple, avocado, cantaloupe, ripe kiwifruit, papaya, green to pink tomato, passion fruit, nectarine, and just about any crop that is disease infested, depending on the pathogen.
    Crops that are sensitive to ethylene include carnation, kalanchoe, tomato, cantaloupe, avocado, lemon, orange, zygocactus, agapanthus, kiwifruit, snapdragon, delphinium, geranium, hibiscus, gypsophila, impatiens, lupine, phlox, salvia, and schefflera.
    Then there are crops that are not very sensitive to ethylene.They include chrysanthemum, gerbera, aster, marigold, ageratum, most cut greens as well as most (but not all) vegetables.
    Crops that produce very low amounts of ethylene include artichoke, asparagus, cauliflower, cherry, grape, strawberry, leafy vegetables like lettuce, potato, and most healthy floral crops. (www.chainoflifenetwork.org)
