Winter Pruning of Rose Trees in the East Bay: Timing and Technique

In San Francisco East Bay (38°F mornings), winter pruning is safe until sustained freezing. For tree roses (hybrid tea or floribunda on a stem):

• Cut main canes to 10 inches (HT) or 12 inches (Fl).
• Cut laterals to 4 inches (HT) or 6 inches (Fl).
• Remove dead, crossing, thin canes.
• Shape top round.
• Stake securely: ties at top, middle, base.
• Mulch base.

Prune now—tree roses bloom on new growth.
