Guide on Storing Gladiolus Bulbs for Vibrant Blossoms the Following Summer
Gladiolus, known for their vibrant and tall flowers, are a popular choice for gardens. Here's a step-by-step guide on how to harvest, cure, store, and replant gladiolus bulbs.
Harvesting Gladiolus Bulbs
The ideal time to harvest gladiolus bulbs is when the leaves turn yellow, typically around September or October. Use a garden fork or trowel to loosen the soil without damaging the corms. Do not rinse or wash the bulbs after harvesting.
Curing the Bulbs
After harvesting, place the bulbs in a well-circulated spot at 70 to 80°F (21 to 27°C) for 2 to 3 weeks. Turning the bulbs every few days during the drying process helps them dry evenly and prevents rot. After drying, brush off the dirt and choose the best corms to save, discarding any that are mushy or have pests.
Storing the Bulbs
Store the cured bulbs in a cool and dry place, around 35 to 45°F (2 to 7°C). Use old paper bags or mesh sacks to store the bulbs, as this allows them to breathe. It is essential to check the bulbs before replanting in spring, discarding any affected by mold or mush.
Preparing for Replanting
Before replanting, soak the stored bulbs in slightly warm water for a few hours to perk them up. Dust the bulbs with rooting powder to kickstart growth. Trim the stems to 1 inch above the corm, and ease them out gently to avoid damage.
Replanting Gladiolus
Plant the bulbs in sunny and well-drained soil for best results. In colder zones (7 and below), it is safer to pull up gladiolus bulbs in fall to lock in blooms next year. In warm zones (8 and up), gladiolus bulbs can be left in the ground if the soil drains well and a thick layer of mulch is applied.
Additional Tips
Avoid storing gladiolus bulbs near apples or pears as their gases will negatively affect the bulbs. When leaving bulbs in the ground in colder zones, mark the spot to avoid slicing them come spring. Planting gladioli in containers is a nice way to add vibrant color to your porch or patio.
By following these steps, you can ensure that your gladiolus bulbs are properly harvested, cured, stored, and replanted, ensuring a bountiful bloom next season.
