Reduce watering significantly during dormancy. Avoid disturbing rhizomes. Remove dead foliage after it dies back completely.
Emerging Growth
November-JanuaryNew shoots and narrow, sword-like foliage emerge from rhizomes in late fall or early winter
Begin moderate watering as temperatures cool. Ensure good drainage to prevent rot. Mulch lightly if temperatures drop significantly.

Keep plants well-lit. Do not remove flower stems unless dead or diseased. Avoid overhead watering to prevent flower damage.
