Question:

When should I cut gladiolus flowers for indoor use?

Answer:

Gladiolus for decorative indoor use should be cut as soon as the bottom flower on the spike has opened.  Most of the remaining blooms will open when the spike is brought indoors and placed in water.  When cutting gladiolus flowers, leave at least 3 or 4 leaves at the base of the plant.  Early morning is the best time to cut gladiolus flowers.
