Hi Keven, If we are talking gladiolus callianthus. I have planted & lifted mine for 6/7 years now. The last two years, they have been very unproductive. This year though, I have a fair number of blooms. I think it is that the bulb has to be the right size/age, the size of a hazelnut. Too old & they're bloomed out, too small & they are immature.
Regardless of whether yours have bloomed this year, after first frost lift them & store in a cool dry spot for the winter. There should also be a lot of little pea sized bulbs you should save too. About 1/2 of these should survive to be planted next spring.

Leaves yes, flowers no. Why don't my irises bloom? I have planted well over 35 bulbs in the last few years.
