Pruning Iceberg Roses for a Dense Hedge: Hedge Trimmer Technique

To maintain an Iceberg rose hedge in Melbourne:

• Prune to 18 inches to thicken base.
• Keep base wider than top for light penetration.
• Use electric hedge trimmer—go slowly for clean cuts.
• Prune after first flush to remove stray canes.
• Disregard single-bush pruning rules; treat as one long plant.
• Mulch for cool roots.

First few years are critical for hedge structure.
