Frequently Asked Questions (FAQs)
1. What month do you plant gladioli bulbs?
Planting gladioli Plant the corms every couple of weeks from March to May for a succession of flowers right through the summer and into autumn. They don't appreciate being planted too early in spring when the soil is too cold – when deciduous trees come into leaf is a good indicator to start planting.
2. Do gladioli come back every year?
Gladiolus come in a riot of colors and will re-bloom every year. Northern gardeners will need to lift the corms in fall and store them through the cold season to protect the gladiolus from freezing temperatures. It would be hard to pinpoint one single reason for a gladiolus to fail to flower.
3. Do gladioli bulbs multiply?
What are the ways Gladioli multiply? Gladiolus reproduces through corms, which are like bulbs. Also Known as cormels, these corms are flat in shape, covered with scale leaves, and can hold tiny corms inside. This smaller corm will grow without producing flowers in its first year when planted.
4. Can you leave gladioli bulbs in the ground over winter?
In warmer regions, gladiolus can remain in the ground through winter, provided a hard freeze (28°F or colder) isn't common in your area. In colder regions (Zone 7 or colder), dig up gladioli corms once the foliage has faded after the first fall frost. A light frost will kill the foliage, but not the rest of plant.
