Water
Allow the soil to dry out completely between waterings. Yucca gloriosa is drought-tolerant once established. Overwatering is the most common cause of root rot.
In winter, reduce watering significantly to mimic its natural dormant period.

Watering, pruning, propagation, and repotting details from plant data
Allow the soil to dry out completely between waterings. Yucca gloriosa is drought-tolerant once established. Overwatering is the most common cause of root rot.
In winter, reduce watering significantly to mimic its natural dormant period.
Prune to remove dead or damaged leaves at any time. To control size or shape, cut back the main stem to the desired height in late winter or early spring. New growth will emerge from just below the cut.
Yucca gloriosa can be propagated from offsets or by planting sections of the stem. Allow cut surfaces to callus over for a few days before planting in well-draining soil. Rooting typically occurs within a few weeks.
Repot mature plants infrequently, only when they become severely root-bound, typically every 2-3 years. Use a well-draining potting mix.
Choose a pot only slightly larger than the current one to avoid excessive moisture retention.
