When can you split gladiolus bulbs?
Splitting gladiolus bulbs, also known as corms, is usually done in autumn. This is the time when the gladioli have finished flowering and the foliage begins to die back. By lifting and dividing the bulbs at this time, you can ensure their continued vitality and prevent overcrowding.
One of the signs that gladioli bulbs need to be split is when they become congested. Over time, the corms multiply and start to cluster together in a tight mass. This can lead to competition for nutrients and space, resulting in smaller and weaker flowers. By splitting the bulbs, you can give each corm more room to grow and thrive.
To split gladiolus bulbs, start by carefully lifting the clumps from the ground or containers. Gently shake off any excess soil and separate the individual corms. You may notice that some of the corms have developed small offsets or daughter corms. These can be detached and replanted separately as well.
When replanting the larger corms, it is important to give them enough space to grow. Gladioli should be planted at a wider spacing to allow for better air circulation and to prevent the spread of diseases. A spacing of 6-8 inches (15-20 cm) between corms is usually recommended.
Before replanting, it is a good idea to inspect the corms for any signs of damage or disease. Remove any soft or rotting parts and dust the corms with a fungicide to prevent fungal infections. This will help ensure the health and vigor of the newly planted bulbs.
In addition to splitting gladiolus bulbs, autumn is also a good time to carry out other maintenance tasks for these beautiful flowers. This includes removing any remaining foliage and stems, as well as cutting back any spent flower spikes. These measures help to tidy up the plants and reduce the risk of disease.
Splitting gladiolus bulbs in autumn not only rejuvenates the plants but also provides an opportunity to propagate them. By dividing the bulbs, you can increase your stock of gladioli and create new plantings in different areas of your garden. This can add variety and color to your landscape.
Splitting gladiolus bulbs is best done in autumn when the plants have finished flowering and the foliage begins to die back. By lifting and dividing the bulbs at this time, you can prevent overcrowding, improve plant health, and create new plantings. It is important to provide enough spacing between the replanted corms and to inspect them for any signs of damage or disease. With proper care, your gladioli will continue to delight you with their vibrant blooms year after year.
