These bulbs have a mechanism that helps to protect them during harsh weather. For example, when there is a drop in temperature, the plants will withdraw and the corms will act as food storage to help survive the dormancy stage. They adjust to temperature changes.
Adequate sunlight and warmth will facilitate growth and help bring the corms out of dormancy.
Soaking gladiolus bulbs can also help to speed up the germination rate which in most cases can save up to 14 or 21 days (2-3 weeks). However, soaking gladiolus bulbs before planting is not a requirement that you must do, it is meant to shorten the length of days it takes to sprout.

- Air temperature between 50 and 70 degrees
- Soaking bulbs (not necessary though)
- Some common varieties of gladiolus flower plants
