Hello, would you, please, tell me how to prepare Gladiolus for winter? I have them first year, they still have green leaves. Should I cut them? How much? Covered? I want to see them next year again. Thank you, Hana

Your gladiolus corms should overwinter without much trouble. Wait until frost kills the foliage, then cut it off at ground level. Mound 4-5 inches of organic matter over the top of the soil to help insulate the ground. You can use pine boughs, pine needles, straw, shredded leaves, or compost as a thick mulch. Brush or rake away the mulch in the early spring and your glads will send up new foliage and flowers. Good luck with your glads.
