Keep soil consistently moist during the growing season, especially when flower spikes are developing. Reduce watering as foliage begins to yellow and die back in autumn.
Avoid waterlogged conditions, which can lead to corm rot.

Watering, pruning, propagation, and repotting details from plant data
Keep soil consistently moist during the growing season, especially when flower spikes are developing. Reduce watering as foliage begins to yellow and die back in autumn.
Avoid waterlogged conditions, which can lead to corm rot.
Remove spent flower spikes promptly to prevent seed formation and encourage the plant to put energy into corm development. Cut back the dead foliage at the end of the growing season, once it has yellowed and withered completely.
Propagate Gladiolus dalenii by separating offsets (cormels) from the parent corms during the dormant season. Replant the cormels in well-draining soil, and they should establish and grow over a few seasons.
Gladiolus dalenii are typically grown from corms and do not require frequent repotting. Corms can be lifted and stored after the foliage dies back, and replanted in fresh soil in spring.
If grown in containers, repot every 2-3 years.
