Sudden Winter Snow on Uncovered Roses: Why Snow Is Actually Protective

Sudden Winter Snow on Uncovered Roses: Why Snow Is Actually Protective

Snow insulates roses. At snowfall, ground is warmer than air; roots keep growing at 40°F. Canes are at freezing, but roots are cozy. A thaw is a good time to add mulch if desired, but don't use soil from around the bush (it's protecting roots). The cold snap won't injure the roses.
