Pruning Roses: Timing, Techniques, and Regional Adjustments

When to Prune

• Repeat-blooming roses: Late winter/early spring, just before dormancy ends.
• Once-blooming roses: Right after bloom period ends; new growth bears next spring's flowers.

Pruning Intensity by Type

• Old garden & modern shrub roses: Minimal—remove dead/damaged wood, lightly shape.
• Hybrid teas & grandifloras: More extensive—shorten previous year's growth, remove weak/old wood for larger blooms on stronger stems.

Pruning Steps

1. Remove weakened or winter-damaged stems.
2. Cut out stems growing at odd angles.
3. Reduce remaining stem length:
   • Mild-winter regions: cut back by 1/3 to 1/2.
   • Cold-winter regions: remove dead/damaged stems after winter protection removal; final size depends on winter severity.
