Protecting Roses from Late Frost

Simple Frost Protection for Rose Gardens

In North Carolina, a late frost warning doesn't have to mean disaster for your roses. Light frosts (above 28°F) rarely harm dormant or semi-dormant roses; it's hard freezes (below 25°F for several hours) that damage canes and buds.

Effective Covering Methods

• Fabric covers – Old sheets, frost cloth, or burlap draped over plants and secured at the base.
• Damp newspaper – 5–6 layers wetted and laid over small bushes; the water releases latent heat as it freezes.
• Mulch mounds – Pile 8–12 inches of straw, leaves, or compost around the base to protect the crown and lower canes.

Key Principles

1. Cover before sunset to trap soil heat.
2. Remove covers next morning once temperatures rise above freezing.
3. Don't use plastic directly on foliage—it transfers cold and causes more damage.

If buds are already swelling, they're more vulnerable. Prioritize covering those plants. Established roses usually recover from minor tip damage by pushing new growth from lower buds.
