Gladiolus Flower Temperature. See your local frost dates here. They look spectacular in a vase and are suitable for growing in flower gardens container gardens and even vegetable gardens.
It is true that if the heat is excessive the flowers can last less time. Plant gladiolus only when the temperature is at least 13 degrees Celsius. I have found from experience that planting corms after March often leads to disappointment.
How Long Does it Take for Gladiolus to Bloom.
The foliage of glads will withstand late frosts. Enjoy continuous bloom throughout summer and early fall by planting gladiolus every 2 weeks from your last frost to early summer. Gladiolus prefers soil temperatures of at least 55 degrees Fahrenheit. Many people choose the vegetable bin in their fridge or an attached garage to store their gladiolus corms.
