Pruning garden gladiolus — FAQ
When should I prune garden gladiolus?
Deadhead after each flower spike finishes; cut back fully before lifting corms in autumn. Cut the spent flower stem at the base once all florets have faded. In autumn, cut remaining stems to a short stub before carefully lifting, cleaning, and storing corms in a cool dry location.
How often does garden gladiolus need pruning?
Once per season. Garden Gladiolus (Gladiolus ×hortulanus) benefits from deadheading spent flower spikes to keep displays tidy and focus energy on the corm. Once autumn frost blackens the foliage, cut stems to 2–3 inches before lifting corms for winter storage in colder climates. Never remove green leaves while they are still functioning — they fuel next year's bloom.
