How do you harvest gladioli bulbs?

To harvest gladiolus bulbs, wait until the foliage turns yellow and begins to die back, indicating that the bulbs are mature. Carefully dig them up using a garden fork or spade, taking care not to damage the bulbs. Shake off excess soil and allow them to dry in a shaded, well-ventilated area. Once dry, trim the foliage and store the bulbs in a cool, dry place until replanting time.
