Gladiolus are vibrant flowering plants that add a splash of color to gardens during the summer months. Properly lifting and storing their bulbs is essential for ensuring healthy growth in the following season. This guide provides expert advice on the best times to lift gladiolus bulbs based on seasonal changes and regional climates.
Understanding Gladiolus Growth Cycle
Gladiolus plants grow from corms, which are underground storage organs similar to bulbs. They typically bloom in mid to late summer, depending on the variety and planting time. After flowering, the plant’s energy moves back into the corms, making it the ideal time to lift and store them for winter.
When to Lift Gladiolus Bulbs
In Temperate Climates
In regions with cold winters, gladiolus bulbs should be lifted after the first frost has blackened the foliage. This usually occurs in late fall, around October or November. Waiting until the foliage has fully died back ensures the corms have stored enough energy for the next growing season.
In Warmer Climates
In areas with mild winters, gladiolus can sometimes stay in the ground year-round. However, for optimal health and to prevent disease, it is recommended to lift the corms in late fall, before the first frost, and store them indoors during winter.
How to Properly Lift and Store Gladiolus Bulbs
Careful handling during lifting and storage helps prevent rot and damage. Follow these steps for best results:
- Wait until the foliage has turned yellow and died back.
- Use a garden fork or shovel to gently lift the corms from the soil.
- Brush off excess soil and let the corms dry in a warm, airy place for a few days.
- Remove any old, damaged, or diseased corms.
- Store the healthy corms in a paper bag or mesh container in a cool, dark, and dry location.
Additional Tips for Gladiolus Care
Proper care extends beyond lifting. Consider the following tips:
- Plant new corms in well-draining soil with plenty of organic matter.
- Provide full sun for optimal flowering.
- Water regularly during the growing season, but avoid waterlogging.
- Apply a balanced fertilizer every few weeks to encourage healthy growth.
By following these seasonal guidelines, gardeners can enjoy vibrant gladiolus blooms year after year. Timing the lifting and storing of corms correctly ensures healthy plants and beautiful flowers in the seasons to come.
