what do in need to do with glads in zone 9 when are done blooming, Can the bulbs be saved ?
Yes, the bulbs can be saved. In your warm region, the bulbs can be left in the ground although gladiolus experts often choose to lift their bulbs at the end of the season.
Allow the plants to stay in the garden until the foliage yellows. During this period the bulbs are gathering strength for next year's show. Then lift, trim and store in a dry, non-freezing location.
