Winter perils for trees and shrubs


Winter can be tough on Iowa's trees and shrubs. Low temperatures, rapid temperature changes, winter desiccation, and the weight of ice and snow can damage vulnerable trees and shrubs.

Iowa is located in USDA Hardiness Zones 4 and 5. The average annual minimum temperature in Zone 5 is -10 to -20 F. The average annual minimum temperature in Zone 4 is -20 to -30 F. The dividing line between Zones 4 and 5 lies roughly from Shenandoah to Ames to Dubuque.
