How to Grow Gladiolus Bulbs
Select a sunny site or container with good drainage protected from wind. Feed gladiolus bulbs regularly during the summer. In the fall, before frost, move indoors, stop watering and store dry at room temperature. When dormant under these conditions, the leaves will die down and no light is required. The following spring, repot and divide if necessary. Plant bulbs 3-5", spaced 6" apart.
