Frequently Asked Questions

Gladioli grow from corms rather than true bulbs. These corms store energy that helps the plant produce strong foliage and tall flower spikes during summer.
Once flowering has finished, leave the foliage in place until it naturally dies back. This allows the plant to feed the corm, improving blooms for the following year.
In milder areas with good drainage, gladioli can sometimes stay in the ground. In colder or wetter gardens, lifting and storing them in a frost-free place is recommended.
Plant gladioli corms in spring once the soil has warmed and the risk of frost has passed. This timing helps ensure strong summer flowering.
Gladioli are perennials when cared for correctly. With good drainage and winter protection, wide varieties will flower again in future seasons.
Yes, gladiolus flowers are excellent cut flowers with long stems and impressive blooms that last well in a vase when cut at the right stage.
