Overwintering Potted Willows in Rocky Mountain Climate

One-gallon willows in Zone 4 (Glacier Park area) need winter protection. Don't plant now—keep potted until spring.

Winter Storage Protocol

Location: Unheated garage/shed (above freezing, below 40°F)
Water: Monthly—roots need moisture even dormant
No fertilizer until spring planting
Spring: Plant after ground thaws, hole 2x pot size

Why Not Plant Now

Fall planting risky in Zone 4—insufficient root establishment
Freeze-thaw cycles heave small root balls
Winter desiccation kills unestablished roots
Spring planting = full growing season to establish

Golden Weeping Willow Specifics

Fast-growing, water-loving. Plant near moisture source. Allow 50+ feet from structures/sewers—aggressive roots. Your trench location south of Glacier Park suggests adequate moisture.
