The main cane of a 26-year-old Cecile Brunner died suddenly after a heat wave; secondary canes are fine. Two nearby Bruners are healthy. Same care for all.
Harsh winters can damage canes internally. The cane survives on stored moisture until a heat wave pushes it over the edge, causing sudden collapse.
Cut the dead cane back to clean, green growth. The plant will rebound vigorously—Cecile Brunner is exceptionally tough.
