Gladiolus, with their tall spikes of vibrant flowers, are a popular choice for summer gardens. Many gardeners wonder if fall is the right time to divide these beautiful plants to ensure healthy growth and abundant blooms in the next season.
Understanding Gladiolus Growth
Gladiolus grow from underground corms, which store energy for the plant’s growth and flowering. Over time, these corms can become crowded, leading to fewer flowers and weaker plants. Dividing the corms helps rejuvenate the plants and promotes better flowering.
Is Fall the Right Time to Divide Gladiolus?
The ideal time to divide gladiolus is typically in the early spring before new growth begins. However, some gardeners opt to divide in the fall, especially if the plants have become overcrowded or if they want to prepare the corms for winter storage.
Pros of Dividing in Fall
- Allows for early replanting in spring.
- Gives the gardener time to inspect and clean the corms.
- Prevents overcrowding and encourages healthy growth.
Cons of Dividing in Fall
- Risk of exposure to winter cold if not stored properly.
- Potential for damage if the corms are not handled carefully.
- Less time for the corms to establish before winter dormancy.
How to Divide Gladiolus in Fall
If you decide to divide gladiolus in fall, follow these steps to ensure success:
- Wait until the foliage has died back naturally.
- Carefully dig around the clump to avoid damaging the corms.
- Gently separate the corms, discarding any damaged or diseased ones.
- Trim the foliage and allow the corms to dry in a cool, dry place.
- Store the corms in a paper bag filled with peat moss or vermiculite during winter.
- Replant in spring after the danger of frost has passed.
Conclusion
While spring is generally the preferred time for dividing gladiolus, fall can be a suitable alternative if proper precautions are taken. Ensuring the corms are stored correctly and planting them early in the spring can lead to healthy, vigorous plants and vibrant blooms in the upcoming season.
