KUSA - Despite the extreme cold, most trees, perennials and shrubs will make it through. Most of Colorado is considered Zone 5 by the USDA, with the foothills and mountains categorized as Zones 4 and 3. Reputable nurseries sell only plants suitable for the region that can withstand very low temperatures. In addition, snow acts as an insulator to protect plants.
Most evergreens withstand cold and snow beautifully. Use cut branches from your garden to create lovely "porch pots." Pine, spruce, cedar and juniper branches may be contrasted with bare branches, seed pods and ornamental grasses. Add silk flowers, berries and bows to finish the arrangement.
For best results, spray cut evergreens - including Christmas trees, wreaths and garland--with an anti-desiccant spray such as Wilt Pruf or Stop Wilt. This pine resin based spray seals in moisture and helps prevent needle drop. It works for both indoor and outdoor evergreen use and makes your holiday displays last well into next year.
