PROBLEM TO BE SOLVED: To provide a method for processing a cut flower, by which the preservability of the cut flower can be enhanced and the flower portion and stem portion of the cut flower can be dyed in natural colors, respectively, without using a solvent harmful to human bodies. SOLUTION: This method for processing the cut flower to dye the flower portion and stem portion of the cut flower into different colors, respectively, is characterized by comprising a stem portion-dyeing process for making the stem portion 12 to absorb a preservation solution 21 containing a dye G approximate to the color of the stem from the lower cut face 13 of the stem portion 12 of the cut power 1, a flower portion-dyeing process for making the flower portion 11 to absorb a preservation solution 22 containing a dye F approximate to the color of the flower from the surface of the flower portion 11, and a separation process for performing a treatment for blocking out a conduction between the flower portion 11 and stem portion 12 of the cut flower, before these dyeing processes are performed. The preservation solution 21 and the preservation solution 22 each comprises at least glycerol, a surfactant and a colorant, consisting mainly of a polyhydric alcohol, does not contain methanol and acetone harmful to human bodies, and is adjusted in response to the characteristics of a plant to be a processing target.
