Frost resistance of Astilbe
Astilbe Buch.-Ham. ex D. Don
Astilbe exhibits high frost resistance, withstanding temperature drops down to -30...-35°C, which corresponds to USDA Hardiness Zone 4. The resilience of the plants directly depends on the state of the root system and requires agrotechnical monitoring.
In the reference 4 varieties crop False goat's beard, where this is mentioned in the description.
Most Astilbe varieties are capable of overwintering without special cover at temperatures down to -30...-35°C. The main indicators of frost resistance for the crop are temperature thresholds or USDA hardiness zones. Young plants that have been planted in their first year have lower winter hardiness and therefore require protective cover.
An important biological feature of Astilbe is the upward growth of the rhizome, which can result in buds being exposed on the soil surface and freezing. To maintain the frost resistance of mature specimens, hilling and regular division of the clump every 4–6 years are practiced. Planting times for the crop are scheduled for spring or early autumn to ensure the adaptation of the root system before the onset of persistent cold.
