The timing of rhizome excavation for these tropical-looking plants is crucial for successful overwintering in regions experiencing freezing temperatures. Leaving the rhizomes in the ground throughout winter in such climates often results in damage or death due to frost. Determining the precise moment for this task is influenced by the local climate and specific weather patterns.
Properly timed excavation ensures the viability of these plants for the subsequent growing season. Digging them up at the appropriate time prevents rot and protects against damaging cold. This practice allows gardeners in colder climates to enjoy these plants annually, treating them as seasonal rather than permanent fixtures in the landscape.
