Overwintering Container Perennials in Colorado

Winter Protection for Potted Perennials

Colorado gardeners can successfully overwinter containerized perennials (Echinacea, catnip, yarrow, lamb's ear, iris, and even young aspen trees) using simple, effective methods.

Recommended Storage Locations

• Unheated basement, garage, or shed: Ideal after plants go dormant; water weekly
• Protected outdoor location: Against a wall or barrier blocking north winds

Critical Care Points

Wait until plants are fully dormant before moving. Water sparingly—just enough to prevent complete desiccation. The key is protecting roots from freeze-thaw cycles and desiccating winds while maintaining dormancy until spring planting.
