ABSTRACT:
A flower stem cutter for an individual flower includes a liquid filled jar having a cover releasably attached. The liquid includes any antibacterial agent and feed. A flower stem guide is secured to a diametrical slot in the cover and projects inwardly into the liquid. The guide is triangular U-shaped unit defining a base wall in spaced relation to the opposite jar wall. The vertical edge of the guide sidewall projects inwardly. A guillotine cutting unit includes a cutting support blade secured to the lower inner end of the guide and a guillotine blade secured to a shaft journaled in the cover, with the guillotine blade abutting the edges of the U-shaped guide. The guillotine blade is resiliently supported on a shaft journaled in the cover for movement past the support blade to sever the stem under the protective liquid. The shaft is manually operated or connected to a small solenoid on the top of the cover. If solenoid operated, the stem may strike a lever in the jar at the appropriate location to energize the solenoid and sever the stem.
