General comments on refrigeration of roses.
FW - Condition roses 15-30 minutes in water after cutting, then submerge vase in conditioned water and insert rose in vase and lift out of water, then refrigerate.
JH - In hot weather, cut the roses tighter. Cutting at a particular stage is more important than refrigeration. Put roses in preservatives for eight minutes and then refrigerate. Cut roses in the evening because there are more fluids in the plant and the plant itself is dryer. Use room temperature water.
JW - At what stage you cut the bloom is the most important, and this varies from spring to fall.
