Question: How do I overwinter gladiolus bulbs?
Answer: Carefully dig up the plants with a spade in late summer/early fall. Gently shake off the soil from the bulb-like corms. Then cut off the foliage 1 to 2 inches above the corms. Dry the corms for 2 to 3 weeks in a warm, dry, well-ventilated location.
Additionally, what to do with gladioli when finished flowering?
Cut off the flower stem at its base after all the buds have flowered and completed blooming.
Water the plants weekly after blooming.
Weed between the gladiolus weekly or as necessary to keep weeds from establishing in the bed.
