Pruning common gladiolus — FAQ
When should I prune common gladiolus?
Remove spent flower spikes after all florets fade (mid to late summer); cut foliage to ground after yellowing in autumn. Cut the spent flower spike back to just above the top leaf, leaving all green foliage standing. Once foliage naturally yellows, cut to ground level and carefully lift corms, cure, and store in a cool, dry, frost-free place.
How often does common gladiolus need pruning?
Once per spike after flowering; annual corm lift and foliage cut-back in autumn. Common gladiolus needs minimal pruning during the season. Remove spent flower spikes once all florets have faded by cutting the spike back to just above the uppermost healthy leaf — leave all foliage intact so corms can rebuild energy. Once leaves yellow in late summer or autumn, cut to ground and lift corms for winter storage in frost-prone areas.
